1. The conformity of the pattern of Cicindela anchoralis to what has been considered typical of the genus becomes in- telligible if the middle band, which is undoubtedly the most variable of the markings of this species, is assumed to have shifted forward and to have developed extensions both cephaled and caudad along the lateral margin and on the disc of the eIytron.2. The variation of the pattern is of the continuous type and proceeds in one principal direction. As expected, some in- dividuals depart from this main series, in one way or another and ten such sub-types have been recognized in this study. The range of variation is very considerable.3. The male sex is found to have a greater tendency to lose its pigmentation, and this fact is interpreted as indicating its having a more variable middle band.4. Mating between the different types is entirely at random, the frequency of any given combination is apparently a function of the abundance of the individuals in a given class.5. In describing the elytral pattern of this species, Chevrolat (1845) used these words: "vitta anchorali, cum lienola pone humerum (femina amplioribus); cupreis". He evidently had regarded as typical the pattern showing fullest pigmentation. The present study shows, on the other hand, that such a pat- tern, while most primitive, is not the most representative. The typical pattern is to be sought in Class Ⅳ, the model class. This last remark certainly has wider application and merits the consideration of taxonomists describing highly variable forms.

斑蝥科甲虫翅鞘色型之差異,在一部份種類中,極为顯著。本篇所論,根據中國种錨紋斑蝥,於廿二年夏採於厦門北岸,計雌雄共九百餘個,內有交配者六十二對,所得結論如下: (一)本種色型,甚为異特。若以美人薛福特氏所立之本屬理想模式色型推解,則其中間淡色横斑,較为移前,其左右則向上下分枝成H形。 (二)此種色型之變異為連續式仝趨一主要方向,但依其變異之分岐,可别为十種副式色型,詳情已於西文中加以討論。 (三)雄虫翅鞘之中間淡色横斑變異較大,其深色紋斑之傾向於縮小亦因之較雌性为甚。 (四)兩性交配,与色型之差異,全無關係。 (五)大部份個數皆呈現中間色型。其趨向於兩極端者(深色或淡色特别發達者)乃屬少数。因此分類學者於記述变異極大之種類時,應发中間色型者為代表。

Although most higher plants are hermophroditic, monoecious or dioeoious plants are not infrequently met with in nature. In some cases, plants or organs of one sex possess greater economic value than those of the other sex. Therefore, to change the sex of plants or vary the numbar of either male or female flowers (usually toward the direction of femaleness) is of both theoretical and practical significance.It has long been observed that the sexuality of plants changes with a change of environmental factors. But those -observed facts received little attention in the past, since they could not be reconciled with the then-prevalent chromosome theory of sex determination. Biologists of the Michurin school believe .that sexuality of plants is but one of the characteristics that the plant exhibits under certain environmental conditions. Thus, like any other characteristic, it is determined by the metabolic conditions of the plants themselves. We are convinced that by changing one or more of the environmental factors, thereby altering the metabolic pattern of the plants, we can successfully control the sexuality of plants for the banefit of mankind.Minina in her monograph has comprehensively reviewed the literature pertinent to the change of sexuality in the plant world under changed enviromental conditions. It has been shown that either treatment with CO, or an alteration of the nutritional status of plants can affect the sex expression of plants.The present investigation purposes to study in greater detail the principles governing the formation of male and female flowers in the cucumber plants.Treatment of the 24-day-old cucumber seedlings with CO gas (at 1%, 0.5% and 0.3%) for 161 hours has remarkably altered the order in which the mala and .female flowers appear. The numbar of female flowers greatly increases, whereas the male flowers do not appear until much later. Marked morphological changes have also been noticed. Physiologically, treated young plants decrease their respiratory activity by 50-70%, as measured at the close of the experimental period. The activity of catalasa has had corresponding changes.When plants are given ample phcspliorus fertilizer successively at the 3-leaf stage, the. stage of bud appearance, and the stage of opening of the female flowers, they bear much more female flowers, whereas the number of male flowers remains unchanged. Plants thus treated also show lower calalase activity hi their leaves.Higher water content of the soil has favored the formation of female flowers. Plants grown under such condition absorb more nitrogen than control plants. This is in line with what is reported in the literature to the effect that high nitrogen is favorable for the development of femaleness.The increase of the number of female flowers is not necessarily connected with the state of the growth of plants. This has led us to believe that it is not the general nutritional status of plants, i.e., the abundance or deficiency of fertilizer, that determines sexuality,The present investigation has clearly demonstrated the possibility that different environmental factors which showed their effect on sex expression may have performed their functions through the same or similar mechanism.The effects of some respiratory inhibitors, including NaN3, malonate, fluoride, etc. are being examined. Investgations are also being undertaken to elucidate the possibility of treatment of seeds with various substances to change the sex ratio of the flowers in the cucumber plants.

在自然界中不少植物是雌雄异株或雌雄同株而异花的。不同性别的植株或花的经济价值不同,因此,定向改变植物性别的问题就不仅仅具有理论上的意义,而且也有着实践上的意义。很早就有人观察到植物性别可随环境而发生改变的事实;但是这些事实没有受到足够的重视,因为它们与性别决定的染色体学说是不相容的。米丘林生物学者认为植物性别的形成和发展也是植物有机体在一定环境条件下所表现的发育特性之一,是决定于植物体内的新陈代谢的。因此,我们深信,通过环境条件的改变,改变植物体内的新陈代谢过程,从而定向地控制植物的性别是完全可能的。 曾详尽而全面地介绍了定向改变植物性别方面的文献。本文目的在于进一步探讨环境条件对于黄瓜雌雄花出现的规律性的影响以及这些影响的生理实质。 在黄瓜幼苗期间用CO(浓度为1%,0.5%,0.3%)处理植株161小时显著地改变了雌、雄花出现的顺序,增加了雌花的数目,降低了雄花的数目。提高了果实的产量。在外部形态方面亦发生了显著的改变。在生理方面,遭受气体处理的植物在处理结束后呼吸强度降低50—70%,过氧化氢酶的活性也有相应的改变。 在植株三叶期、现蕾期、雌花开放期均施以充足的磷肥,这种处理选择性地增加了雌花的数目,而...

1. This paper describes the structures of the tympanal and sound-producing organs of acicada, Cryptompanal pustulata Fabr. It is commonly found in Peking and its vicinities insummer days. 2. The main parts of the tympanal organ of this species of cicada are the following: the tym-panal membrane, the tympanal scoloparium and the tympanal nerve. The full realization of thesense of hearing is assumed to be dependent upon a series of devices: the tympanal membranereceives the sound waves from the exterior, the accessory chitinous structures (tympanal ridge andspatula) transmit the sound vibrations to the scoloparium, the latter gives rise to the nerves im-pulses in its nerve cells and, by way of the tympanal nerves, this kind of impulses proceeds tothe central nervous system. 3. The tympanal organs in the male cicada are fundamentally the same in structural plan asin the female, only the form and size of their corresponding parts differ slightly. Furthermore,the female cicadas have no sound-producing organs, hence the morphology of certain of theirabdominal segments is correspondingly different. 4. In the male sound-producing organs the author discovered one muscle (auxilliary muscle)and two sense organs (scaloparium of sound-producing membrane and scoloparium of foldedmembrane); all of them were not found to have been described in the past-day literature. Theauthor not only described these structures morphologically in detail but also made some preliminarysuggestions for their functions.

1.本丈研究蚱蝉的听器和发声器的构造,所用材料为北京近郊夏季常见的一种蚱蝉Cryptotympana pustulata Fabr. 2.蝉的听器主要分为听膜、听觉剑鞘器和听神经三部分。听膜承受外界声波,它又倚靠附属的几丁构造(听脊和铲状片)而把振动传给听觉剑鞘器,后者引起神经冲动的产生,再由听神经将这种冲动传到中枢。 3.雄蝉和雌蝉听器的构造基本上是相同的,只是相应部分在形态上和大小上有些差异。此外,雌蝉没有发声器,因此腹部形态也有些不同。 4.作者在雄蝉发声器上发现一条肌肉(协作肌)和两个感官(声膜剑鞘器和褶膜剑鞘器),是过去文献中没有记述过的,本文不仅详细描述了这些构造,并且也初步推测它们的机能。
