The general histological structure is fundamentally similar to that of the skin of frog (Pl. Ⅰ, Fig. 1). In the superficial layer of the dermis there are large and conspicuous round masses, which are akin to the sieve layer (Siebschicht of Kastschenko) both in appearance and in staining reaction (Pl. Ⅰ, Fig. 1; Pl. Ⅳ, Fig. 6).

The general histological structure is fundamentally similar to that of the skin of frog (Pl. Ⅰ, Fig. 1). In the superficial layer of the dermis there are large and conspicuous round masses, which are akin to the sieve layer (Siebschicht of Kastschenko) both in appearance and in staining reaction (Pl. Ⅰ, Fig. 1; Pl. Ⅳ, Fig. 6). To our knowledge, the origin and function of these masses as well as the sieve layer are still obscure.According to the living habit, the life of the toad during the year can be divided into three seasons: namely, the hibernating, the breeding and the post-breeding season.In the hibernating season the epidermis reaches its maximal thickness due to increase in cell layer as well as in cell size. Cell division is rare in this season. The superficial layer is evenly cornified and the intensity of comification is intermediate, being stronger than that in the breeding season but less than that in the post-breeding season. This horny layer is connected intimately with the layer below and shows no sign of moulting (Pl.Ⅰ, Fig. 1; Pl. Ⅱ, Fig. 1). The flask-cells of Pfitzner (nucous cells of Legdig or goblet cells of Schultze) are very rare and when present, they are not fully differentiated from the ordinary epidermal cells. Melanophores are greatly expanded both in the epidermis and in the dermis (Pl.Ⅳ, Figs. 4, 3). Dermal papillae are tall and prominent (Pl. Ⅱ, Fig. 1).In the breeding season the epidermis is much thinner than that in the hibernating season. Moulting of skin goes on continuously. In association with moulting the flask-cells increase in number and show vigorous activity in secretion (Pl. Ⅱ, Fig, 2). Numerous amitoses are present in the middle and lower layer of the epidermis. At the initiation of the amitotic division a furrow appears at one side of the nucleus, which deepens and finally cuts the nucleus into two. Sometimes two furrows are formed, causing one nucleus to break up into three. A furrow may start at one end of the long diameter of the elliptical nucleus, causing it to split longitudinally into two daughter nuclei (Pl. Ⅰ, Fig, 2). We call this mode of amitosis furrowing amitosis. The usual mode of amitosis in which the nucleus divides by a central constriction could be found also, but cases are very rare. Mitotic figures are very rare. Melanophores are more or less contracted in the epidermis as well as in the dermis (Pl. Ⅱ, Fig. 2).In the post-breeding season the epidermis is intermediate in thickness between those of hibernating and breeding seasons. Due to the dryness on land the certification of the superficial layer is intense. Sometimes there are three layers of highly cornified cells, while in the other seasons this layer is always simple (Pl. Ⅱ, Figs. 3, 4, 5). Both mitosis and amitosis are present (Pl. Ⅱ, Figs. 6, 7). The former is much more in number than the latter. Wandering cells in the dermis penetrate into the epidermis and become epidermal cells (Pl. Ⅲ, Figs. 1, 2, 3). Flask-cells are fewer in number and less in activity than in the breeding season, hence the moulting of skin goes on slowly. All the melanophores are contracted in the form of a black spot (Pl. Ⅱ, Figs. 3, 4, 5). The blood vessels in the epidermis are greatly expanded, and are therefore easily seen (Pl.Ⅳ, Fig. 6).The nuclei of certain epidermal cells send out processes, which penetrate through the cell membrane and move along the intercellular spaces (Pl. Ⅲ, Figs. 4, 6). Sometimes these processes get into the neighboring cells (Pl. Ⅲ, Figs. 7, 8). In still other cases nuclei sued out coarse processes which come into contact with identical processes sent out by nuclei of neighboring cells (Pl. Ⅲ, Fig. 5). So far as we know, such intercellular activity of nuclei of the epidermal cells has not been heretofore repoifted. Its significance probably lies in the transportation of certain substances such as DNA. Nuclei showing this activity stain more intensively with Feulgen.The above description applies to the typical structures in each season. It is found that at the time between two se

Consideration on various grounds has led to the inclusion of three new species ofladybeetles in the Coccinellidae fascicle of the Economic Series of the Chinese InsectFauna, now going to the press. To make available the species names proposed and tofacilitate future reference, new species descriptions are herewith published in advance inthis journal. In the course of the present study, the external genitalia of both the male andfemale sex have proved, as of wont, exceedingly helpful in species discrimination. Es-pecially worth mentioning is a hitherto neglected structure--the basal "handle"-like por-tion of the genital plate or the "Stiel" in Verhoeff's terminology, which has shown pos-sibilities of being more widely made use of in future investigations of Coccinellid taxo-nomy. It first attracted attention in the comparative study of the female genital platesof Coccinella undecimpunctata and C. geminopunctata(a new species to be describedpresently), two forms closely resembling each other in point of elytral pattern but differ-ing widely if genitalia are taken into account. This basal portion of the genital plateof C. 11-punctata is short and bluntly rounded at the end, whereas that of C. gemino-punctata is long and crenate at the corresponding point. Again in the three species ofBallia studied, B. obscurosignata sp. n. has a hooked end, while in B. korschefskyi andB. didnae, the end is branched though in quite different manners (fig. 3, A & B). Forthe sake of easier reference, the term capulus (Lat., a handle) has been proposed. The three new species described in this paper are: Coccinella geminopunctata, C.longifasciata and Ballia obscurosignata. Coccinella geminopunctata resembles closely C. undecimpunctata in having an identicalnumber of black spots (11 altogether) and in their general disposition on the elytra, butmay be readily distinguished by its two apical spots being at one level in contrast to thefore-and-aft placement in the Linnaean species. Their genitalia are evidently of verydifferent types. The penis in the new species has a wedge-shaped cleft at about themiddle on each side, while the 11-punctata penis has the sides entire. But the greatestdifference is shown in the capulus as discussed in the paragraph immediately preceding.In point of general form of the penis, C. geminopunctata shows similarity to C. trans-versoguttata, a species with totally different elytral pattern. The new species can more-over be distinguished at sight by its larger body size. Coccinella longifasciata distinguishes itself by having a longitudinal black stripe onthe elytral disc, besides one on the suture. The elytral stripe, by virtue of its obliqueposition, offers a clue to its having possibly been derived from the basic pattern ofDobzhansky (1926) (fig.4), with the extension and confluence of spots 1, 3, 5 and theoblitration of the two lateral spots. So far as the writer is aware, this type of patternis quite rare, if not unique, in the genus Coccinella. In the male genitalia structures, C.longifasciata shows some resemblance to C. trifasciata in the shape of the penis but differsin having the basal portion narrowed, whereas in the other it is wide throughout. It isalso obvious that the coalescence of the spots is longitudinal in one and transverse in theother. Ballia obscurosignata is characterized by the peculiarity shown in the indistinctnessof the white-colored pattern, which, moreover, is quite variable. The genitalia conformto the type of the genus but in the capulus it shows an individuality not approached bythe two congenric species (B. korschefskyi and dianae) currently investigated. This specieswas found on pine trees both in the north and the south, and is evidently an aphidfeeder. As an adjunct to this study and a continuation of a previous effort (Liu, 1950),proposals have been advanced to revise and supplement the Chinese terminology of thegenitalia structures of the Coccinellidae.

由于不同的原因,弯斑瓢虫(Coccinella geminopunctata),纵条瓢虫(C.longifasciata)和隐斑瓢虫(Ballia obscurosignata)三个新种被认为应当包括在即将付印的《中国经济昆虫志:瓢虫科》一书中。为了便于使用新种的学名,更为便于日后的查考,特先在学报发表该三种的记述。 就如在其他分类工作中一样,雌雄两性的外生殖器对种的辨识起了很大作用。在这次工作中,发现雌瓢虫的生殖片基部柄形部分在各种中有相当的差异,可能发展为有用的特征,因此命名为“基柄”(ca-pulus)。 继1950年的尝试,本文对瓢虫外生殖器的汉文名词做了一次增补与修订。
