 complete on the left aide; but on the right side, in addition to the + parts being cora- 

 plete, some ,' parts also seem to be represented. The genitalia are illustrated in the 

 plates, together with those of normal rj" and i for comparison. H. Scott (Cambridge).

 indigenous African silkworm {Anaphe infracta Wlsm.) in Uganda. 

 In: Bull. Ent. Research, Bd. III, Heft 3, S. 269—274, 2 Textfig., 1912. 



The most numerous silkworms in Uganda are 3 spp. of Anaphe (Farn. Eu- 

 pterotidae). 2 others, Mimopacha gerstacdxcri Dew. and Hypsoidcs milldi de Juan, 

 are comparatively rare. Anaphe infracta has 2 broods in the year. The life-cycle 

 •of each occupies about a year, hence the tvvo broods overlap, one emerging in 

 •September and the other in January: in the September brood the pupal stage 

 lasts about 13 Aveeks, in the January brood about 6 weeks; otherwise the duration 

 •of the stages is not very different. The eggs are laid on the underside of the 

 leaf of the food-plant in Clusters of 200 — 300. The larvae feed in groups, very 

 voraciously, and dislike sunlight. When full-fed they spin large silken nests in 

 the bifurcations of the branches. Each nest contains from 120 — 600 or more 

 larvae. The nest is composed of 3 envelopes, an outer consisting of very fine 

 silk, a middle composed of several silken layers, and an inner envelope of the 

 texture of parchment, hard and resistant. The layers contain urticating hairs 

 derived from the bodies of the larvae. The larvae remain some time in the nest 

 before pupating: each one spins a small separate silken cocoon. Several food- 

 plants are mentioned, the principal one being a shrub, Bridelia micrantha. Methods 

 of rearing the larvae and treating the nests are described. 3 species of birds 

 are known to prey on the larvae. The eggs are parasitised by a minute Procto- 

 trupoid (Telenomus), which in its turn is hyper-parasitised by another Hymenop- 

 teron (Pleurotropis). 2 parasites, a Tachinid fly and an Ichneumonid (Cryptus), 

 have been bred from the cocoons. In West Africa, in addition to the Ichneumonid, 

 larvae of 2 species of Pyralid moths {Metoccis) have been found infesting the cocoons.
