Ericerus pela Chavannes, the insect producing white wax,belongs to Coccidae,Homoptera. The female adult lays eggs while the male larva produces wax, whichis a well-known product from Southwest China. The wax secreted by the malelarvae may be boiled and extracted to result in something known as white wax.Its boiling point reaches above 82-83℃. It has manifold uses. Before WorldWar Ⅱ, besides the consumption at home, th greater part of this product wasexported abroad. The supply of the female adults of this wax insect in the wax-producing districtusually appears short annually, due to a peculiarity in the growth of this creature;and therefore naturally exist two correlative districts, that is a district of adultproduction and one of wax production. As these two.districts are located morethan 500 kilometres apart,every year the female adults ready to be transplantedon he feeding trees in the district of wax production have to be supplied bythe district of adult production, and they must be carried over a long distance.The carriage of the female adults of the wax insect from one place to theother has been practiced for about five hundred years by the people engaged inwax production. This article reports on a test of transportation of the female adults of the wax insect from Paikuowan (白菓湾) in Hweili County (会理县), formerly of SikangProvince to Huhtaokou (核桃沟) in Omei County (峨眉县), Szechwan Province.Investigations in this connection were made from the April 30 to May 13, 1941. It has long been the aim of the growers to produce the female adults of theinsect and the wax in the same locality. With this realized, the area of wax pro-duction would be enlarged, and the quantity of wax increased. However, as the female adults of the insect in the distr .ct of wax produc-tion are subject to such natural adversities as geographical features, temperatureand humidity, parasitic enemies etc., up to the present they cannot be raised andsapplied insufficient quantity in this district. For this reason, to in prove themethod of transporting the adults female insects to the wax-producing district, toShorten the time on the way,and to increase the vitality of the male larvae-all these have become the crucial questions in the promotion of wax production. The principal explanation, knowh for centuries, with regard to the impossi-bility to raise the female adults of the insects in the district of wax productionhas been the peculiar fact that the female larvae could not be carried in quickorder to a place over 500 kilometres apart. The present test has proved that al-though the female larvae were, in the greater part, hatched out on the way, therewere still a part of them reaching the destination in safety. Valuable informat-ion was also obtained on the hatching rate of the male and female larvae on theway, the influence of environmental factors on the sex ratio, the different speciesof parasitic enemies, etc.. It is hoped thet the facts thus ascertained will be ofservice to improving the methods of wax production.

白蜡虫是我国的特产,古代农民远在元朝已有饲养。在过去全国的白蜡年产量约在五万至十万担间,据1918年重庆海关报告有一万一千余担,值银七十七万余海 关两。解放前一、二十年来,由于国民党反动派的不重视和摧残,已逐渐衰落。白蜡是化学工业上的重要原料,用途很广,饲养蜡虫又是西南各省农民的主要副业,而且农民群众已积累了非常丰富的传统经验。因此,为了总结群众经验,发扬科学遗产,改进饲养技术,振兴蜡业,我们希望能引起有关方面的注意和进一步研究,除研究改进白蜡虫的经管技术外,又须注意白蜡在工业上的用途。 白蜡虫的种蜡异地繁荣,在目前已成为自然的形势,而蜡种虫不能自给,是白蜡业发展上的基本障碍。我们通过本次测验之后,认为我国适于蜡虫(雄虫)繁育的地方很多,如四川、湖南、浙江、安徽、福建、江西、江苏等丘陵地带都可扑虫产蜡,关键问题在于改善运种方法。在目前我国交通运输业已有普遍发展的基础上,只要用航空运种即可在短时间内将种虫运送至全国蜡。扩大蜡,增加农民副业收入,发扬我国科学遗产,为国家创造财富,利用益虫为生产服务,在目前已完全有实现的可能。

1. In South Sinkiang, eggs deposited by the migratory locust, Locusta migra-toria migratoria L., in Aug. 1952 hatched ih the latter part of April, and adultsemerged on June 6 the following year. This species has only one generation ayean and the eggs remain underground for a period of 8 months. 2. Calliptamus italicus L. can be easily identified by the presence of a longprosternal spine between the fore coxae. The distal portion of the cercus inthe male individual is divided into three lobes, the middle one being shorterthan the upper one. 3. Heavy damage was done to pasture land by Gomphocerus sibericus L.. Thisspecies is characterized by the swellen terminal segments of the antennae. Inthe male individuals, the tibiae of the fore legs are also enlarged. 4. Dociostaurus kraussi Ing. may be identified by the presence of an X-shaped marking on the pronotum and the much eniarged markings on themetazone. 5. Ramburiella turcomana F-W. has a slant face Which meets the vertexat an acute angle. Besides the X-shaped marking on the pronotum, there isanother broad line running along the median ridge. 6. The distinguishing Character of the grasshopper Oedaleus decorus Germ.is the blackish band that runs across the hing wings. The pronotal medianridge is high, with a very promineat X-shaped marking on its sides. 7. In Sphingonatus salinus (Pall) the small prozone with a high median ridge,and the two bands across the hind wings are quite characteristic. 8. In this paper distributions of the above-mentioned species are listed. Des-criptions of the egg capsules and the sculpturing on the egg shells have beenmade for the purpose of facilitating specific identification in the field.

A pigmented mass, dendritic in shape, showing on each lateral lobe Surrounding respiratory area, non-pigmented. Posterior sinus trapezoidal Diameter of sucking disk about 1/6 width of carapace, chitinized rods in sucking disk 43-49 in number. Abdomen 0.63-1.13 mm in length and 0.36-0.94 in width longer than broad. Anal papillae basal. Anal sinus about 1/2 length of abdomen.Male: Generally smaller than female, 3.00-4.32 mm in total length. Carapace 1.93-3.48 mm in length, and 1.98-3.18 mm in width. Abdomen, 0.68-1.01 mm in length, and 0.57-0.93 mm in width. Second pereiopod possessing a mitral-shaped process on posterior edge of coxal segment. Third pereiopod possessing a semicircular-shaped posterior capsule on posterior edge both of coxal and basal segments. Fourth pereiopod possessing a projected peg on top of basal segment.The first maxillipeds of three different stages of the larvae in metamorphosis are described. By basing upon the fact shown in the metamorphosis of the first maxilliped of the larval stages, the genus Huargulus seems to be one of the larval stages of the genus Argulus. So the genus Huargulus becomes invalid.This new species was secured from, the lateral line, the surface of abdomen, the gills, and the mucous membrane of the oral cavity of the yellow-barbeled catfish. The last-named location of the parasite is for the first time recorded.
