Hepialidse. 

 21. Gorgopis niphonica, n. sp. (no. 236). 



Primaries above olive-brown, shot with rose-colour towards 

 the outer margin ; the subbasal area darkest, marked with two 

 unequal white dots placed obliquely ; a spot closing the cell, 

 an irregular discal series doubled above the median vein, and 

 a marginal series deep olivaceous : secondaries greyish brown, 

 shot with rose-colour ; fringe brown, spotted in the middle 

 with cream-colour : thorax olivaceous ; abdomen greyish 

 brown. Under surface bronzy olivaceous, tinted with rose- 

 colour. Expanse of wings 1 inch 4 lines.

 22. Cymatophora plumbea, n. sp. (no. 625). 



Silvery grey, primaries more metallic and less brown in 

 tint than the secondaries ; basal area crossed by six parallel 

 blackish irregular lines, the three outer of which are thicker 

 and more distinct than the others ; a widely sinuated blackish 

 line beyond the cell, followed immediately by two or three un- 

 dulated parallel white-margined grey lines ; veins on the disk 

 alternately black and white ; outer border broadly dusky, 

 crossed by a white line limiting the dots on the veins ; a wavy 

 marginal blackish line ; fringe sordid white, traversed by 

 a dusky line : secondaries pale brownish, with broad diffused 

 brownish external area, a whitish discal stripe, and a well- 

 marked blackish dorsal tuft: thorax white, speckled with 

 black, giving it the appearance of the colour of the pri- 

 maries. Under surface pale whity brown, shining; a white- 

 bordered dusky discal stripe ; pectus white. Expanse of 

 wings 2 inches.

 Notodont: palpi much broader than in Acronycta, legs hairy; 

 pectus clothed with long hair. Type B. extensa. 



23. Belosticta extensa, n. sp. (no. 739).
