In this paper the general synthesis problem of optimal control systems with the criterion of transient responses as a positive integral functional (3) is discussed.In the first part it is assumed that the motion of controlled object is described by a system of ordinary differential equations and that the final states of the system form a bounded and closed convex region in n-dimentional euclidian phase space. A method is proposed for finding all optimal control functions which lead any starting state into the given final region of states. Some conclusions are obtained from the maximum principle by using transversal conditions of optimal trajectories in terminal points, and the particular properties of the stated problem are pointed out. The case of linear dif-ferential equations with integral quadratic functional criterion is investigated in detail.Further, in the second part the fundamental properties of isoloss regions, the rela-tions between the isoloss region and optimal control functions are indicated. As a direct result a partial differential equation determining the optimal loss-function J (x) is found and the connection between function J (x)and optimal vector control function u (x) is also stated. The methods proposed are practically the extension of the me-thods used by us for designing time optimal control systems as seen in [5, 6 ,7].Finally, an example is illustrated with optimal trajectories shown in phase plane.The necessary numerical data is calculated by an analog computer with high accuracy.

The present paper gives a report on the observations of the citrus psylla, Diaphorina citri Kuwayama, found in Focchow and Changchow of Fukien Province. The insect has been reported as an important citrus pest in south-eastern Asia, and is heretofore recorded from Kwangtung by Hoffmann (1936) and from Taiwan by Shiraki (1934). The citrus psylla attacks l3 species of plants of the family Rutaceae. Eggs are laid on the leaves of the young growth. The feeding of both the nymphs and adults on foliage of the new terminal growth results in the leaves, becoming thick and leathery. The leaves and the young shoots are usually distorted, dwarfed, or in severe cases, even dried. The annual life cycle of the insect in Fukien Province has not been investigated thoroughly. However, preliminary observations made during the year of 1952 show that different developmental tsages of citrus psylla could be found all the year round. There is no marked phenomenon of hibernation. Concentration of a number of adults on the same leaf usually occurs during the winter months. Both nymphs and adults become very abundant in April when dam- ages are most severe. Sixteen days are required for the insect to complete a generation in August. The number of individuals de- creases after September. The nymphs are attacked heavily by three species of chalcid parasites of the family Encyrtidae. Morphological descriptions of the different stages of the insect are also given in this paper.

柑桔木虫分布于亚洲东南的热带和亚热带地区,为害芸香科植物,是柑桔类主要害虫之一。国内除台湾、广东外,其他各地尚无报告。现知福建的福州、漳州也都有,本文系在福州观察的记述。成虫栖息取食常在芽和叶里的叶脉上。产卵于嫩芽,若虫孵化后就在新梢为害。被害叶芽枯干,枝梢萎缩,新叶畸形卷曲。生活史尚待详细研究,但根据一年来的初步观察,一年到头都可以找到各个虫期;自四月以后为害渐见严重,至九、十月则逐渐减少。夏季完成一个世代约需十六天。冬季多以成虫密集叶里,但无休眠迹象。育得跳小蜂科寄生蜂三种,九月至十一月若虫被寄生者甚多。本文对于柑桔木虫各期形态有简略的叙述。

A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn with this phenomenon. From a study of the variation in a large number of specimens of B. gowkongensis sp. nov., the author considers B. opsariichthydis Yamaguti, 1934 a synonym of B. achilognathi Yamaguti, 1934.SPECIFIC DIAGNOSIS: Bothriocephalus Rudolphi, 1808 emended Lühe, 1899, with generic characters. About 35-80 mm. in length and 0.5-1.2 mm. in width. Segments with or without distinct segmentation. Slight indications of secondary segmentation might occur in all segments. Immature segments broader than long, mature segments square and gravid segments longer than broad. Scolex large, fleshy, heart-shaped with distinct terminal disc and well-developed fleshy bothria. Inner longitudinal muscle bundles extremely weak and sparsely scattered. 50-90 testes. Cirrus immediately in front of vagina. Cirro-vaginal aperture median or slightly lateral between mid-line and posterior third of segment. Ovary near posterior of proglottid. Uterus convoluted, voluminous, and confined to median field. Uterine sac-may encroach on posterior border of preceeding segment or be placed some distance away. Vitellaria in complete circle in cortex. Like the testes, they are continuous from segment to segment. Eggs thin-shelled, operculated, fully embryonated when laid, measuring 33-38 53-54μType host: Ctenopharyngodon idellus.Habitat: Intestine.Type: To be deposited with the Department of Parasitology, Hun-Nan Medical College, Canton, China.Co-types: In author's collection, and to be deposited with the Depertment of Biology, Chung-Shan University, Canton, China.

1.文中记载草鱼腸中新种絛蟲B. gowkongensisn. sp. 是由广东九江採得的。 2.本蟲促使宿主的死亡率,使淡水渔业受到很大的损失。 3.由头槽絛蟲生活史的初步观察,发现它的卵排出时,已有发育完全的胚胎。 4.从研究大量新种标本的变化中,作者认为B. opsariichthydis Yamaguti, 1934是B. achilognathi Yamaguti, 1934的同种异名。
