Family PSYCHID.E. 



CLANIA MINUSCULA Butler. 

 MINO-MUSHI. 



Food plant: Tkea chmeiisis. 



The bags are shown in various stages, a full}' grown larva and the 

 male pupa. The bags and larvaj are so similar to the North American 

 Thryrldopteryx ephemereeformis that a separate description is unnec- 

 essary. 



Family ZYGAENID^. 



ILLIBERIS PRUNI, new species. 

 HOSHI-HAMAKI-KEMUSHI. 



This species was named b}" Doctor Holland ^^Procrls nigra Leech," 

 and Mr. Nawa had the same identification. It is certainly incorrect, as 

 Leech says of Procris nigra "" female antennie simple,"" whereas in the 

 specimens before me they are pectinated in both sexes. 

 The specimens agree with Leech's ligure of Nortlda 

 dirce, except that there is no black apex to fore wing; 

 they disagree with Butler\s figure of JVorthia. te)iHlK in 

 having the a})domen blackish without green tint. I 

 have sixteen specimens without trace of green. They

 PRUNI, LAEVA. ^^-^ ^^ ^^ doscly alHcd to tetmis, but the coital area 

 of hind wings not blackish. It is, however, ])lackish in my specimens. 

 Besides these, Leech mentions from Japan .sinensis Walker, nigra 

 Leech and j»<ijcldna Oberth., ])ut I can not I'econcile the descriptions 

 with my specimens. Of course this form has been received from 

 Japan before, but it must have been referred wrongly, if the descrip- 

 tions are to be relied upon. 



Wings hyaline, veins and margin narrowly black, costal and internal 

 areas of fore wings and costal area of hind wings black shaded, 

 Antemife greenish; thorax and abdomen brown black. 

 Food plant: Pyrim annnvunis. 



The larva has the structure of the European species of Adscita, the 

 warts low and flattened, with short hairs onl\\ Dorsum pale (green if), 

 su))ventral region reddisli, warts concoloi'ous. A black dorsal band, 

 widened on the segments and a subdorsal round spot on each segment 

 I (flow the subdorsiil wart. Head marked with black; cervical shield
