1890.] F. Moore— Ori some Indian Psychidea 26>f5 



Psychids — one of which is found in the Calcutta District, the other in 

 the N. W. Himalayas. These two forms are as follow : — 



Genus Rasioota (Moore). — Wings sparsely clothed with short 

 whitish hair-like scales. Forewing short, narrow, triangular ; costal 

 margin arched before the end, apex somewhat acute, exterior margin 

 oblique, posterior margin short ; costal vein short ; subcostal vein three- 

 branched, second and third starting from end of the cell ; the cell 

 narrowest at its upper end ; discocellular veinlets oblique, angled out- 

 ward ; radial vein from their angle ; a discoidal veinlet emitted within 

 the cell from end of lower discocellular ; median vein four-branched, 

 the two upper branches on a foot-stalk from end of the cell ; submedian 

 vein with a lower branch from its middle towards the base. Hindwing 

 short, apex convex ; subcostal vein two-branched ; radial vein from 

 below end of the cell ; discoidal veinlet within the cell from end of 

 lower discocellular ; four median branches ; a submedian and an inter- 

 nal vein. Body moderately robust, abdomen extending beyond the 

 hindwings ; antennse bipectinated, plumose. 



Rasioota albescens (Moore). — Fuliginous- white, wings and body 

 sparsely clothed with short whitish hair-like scales ; antennas and anal 

 segments fulvous-yellow. Expanse y^^ths of an inch. 



Habitat. Calcutta District {Arthur Grote). 



This species forms a long, narrow, somewhat naked fusiform silken 

 case. 



Genus MoFFATiA (Moore), — Foreiving long, rather narrow, apex 

 somewhat acute, exterior margin oblique, posterior margin short ; costal 

 vein stout, distant at the base from the costa and extending two-thirds 

 from the base ; subcostal vein slender, scarcely apart from the costal, 

 four-branched, the fourth or lower branch extending to a little below 

 the apex, the first branch emitted before end of the cell, second branch 

 from end of the cell, third branch at half-way between the cell and 

 the apex and terminating on the costa above the apical angle ; discoidal 

 cell long, reaching two- thirds of the wing, very narrow at the base and 

 widening out at the end ; discoidal veinlet within the cell, slender, 

 anastomosing with the median vein near its base ; upper and lower 

 discocellular veinlets of equal length, bent inward at their juncture ; 

 two radial veins, one from the upper end of the discocellulars, the 

 other from the angle of their junction ; median vein stout, four-branch- 

 ed, the two lower branches extending to near the posterior angle, 

 the two upper to middle of the exterior margin and anastomosed at 

 their base ; submedian vein long, extending to the angle, recurved, 

 with a wide interspace between it and the median vein, and emitting a 

 short, straight lower branch at half its length. Hindwing short, trian-
