21. Prismosticta hyalinata, n. sp. 



$ Allied to P. fenestrata, from Darjiling (of which I only 

 know the female) but differing besides its small size and pec- 

 tinated antennae, in the uniform darker brown colour of the 

 primaries, in the oblique black spot at the end of the cell, in 

 the elongated hyaline sub-apical spot, rounded internally and 

 notched externally, and with a small hyaline dot obliquely 

 beyond it ; the secondaries have the paler costal area replaced 

 by bright clear ochreous, and the diffused paler ochraceous anal 

 patch by bright golden ochreous, whilst the remainder of the 

 Aving surface is darker and the lines are more oblique and black. 

 Expanse of wings 30 mm. 

 Nikko (H. Pryer). 



This may, of course, turn out to be the male of P. fenestrata, 

 but it seems hardly probable considering the differences in 

 pattern ; its general aspect is that of a gaily coloured Orgyia. 



22. Andraca gracilis, n. sp. 



$ Allied to A. trilochoides, from Darjiling; smaller, of a 

 narrower more elegant form ; more uniformly coloured ; pri- 

 maries pale foxy red- brown with a pink gloss, with the three 

 darker angular oblique lines and black discocellular dot of the 

 Indian species; a foxy red-brown external diffused border; 

 secondaries with costal half pale testaceous, shading into foxy 

 red-brown towards the abdominal border ; fringe brown and 

 Avhite ; a minute brown discocellular spot ; body dull reddish 

 testaceous; the back of the head and the antenna? white; under- 

 Burface glossy goldeti testaceous, with two reddish-brown discal 

 lines as in A. trilocJwides but paler; discocellular dots also red- 

 brown. Expanse of wings 46 mm. 



Nikko (H. Pryer). 



The smaller size, paler colouring and absence of all j^early 

 shades and markings readily distinguish this from the Indian 

 species.

23. Drymonia circumscripta, n. sp. 



$ Unlike the known species of Drymonia in pattern, though 

 agreeing with them structurally ; primaries white, densely irro- 

 rate<l \\\\\\ red-brown and grey, which gives the Avhole ground
