21. Endotricha heliopa, n. s. 

 (^ , 21 mm. Head, palpi, antennae, thorax, abdomen, and legs 

 ochreous-yellow. Fore wings triangular, rather elongate, costa 

 slightly sinuate, moderately arched before apex, apex obtusely 

 angulated, hind margin somewhat oblique, bent in middle ; deep 

 ochreous-yellow, becoming light purplish towards hind margin, 

 except on costa, basal third mixed with pm-plish ; some minute 

 scattered black scales ; a slightly iiTegular-curved pale yellow line 

 from two-fifths of costa to two-fifths of inner margin ; a dark fus- 

 cous diseal dot ; an almost straight indistinct pale yellow line from 

 four-fifths of costa to a little before anal angle ; a blackish widely 

 interrupted hind marginal line ; cilia ochreous-white, basal third 

 carmine-fuscous. Hind wings rather light pm-ple, finely irrorated 

 with blackish ; costa broadly pale whitish yellowish ; a rather 

 narrow deep ochreous-yellow median band, slightly curved, mar- 

 gined by slender pale yellow lines, beyond which is a darker 

 purplish shade ; hind marginal line and cilia as in fore wings. 



Eather like E. pyrosalis, but broader-winged, more 

 distinctly marked, and with the hind wings purplish 

 towards base, the yellow colour restricted to a well- 

 defined median band ; it differs also in venation, as 

 noted above.
