Genus Keingana. — Imago. — Male. Forewing obtusely truncated at the apex. 

 Hindwing narrowed posteriorly and anal angle more prolonged than in Thaumantis; 

 furnished with two conspicuous superposed conjoined glandular patches, each with a 

 nacreous border and tuft of hairs ; the upper patch being situated above the base of 

 the subcostal, and the lower patch within the cell ; the cell is much broader across 

 the middle : and the first subcostal branch emitted at fully two-thirds from the base of 

 the cell. Type. — K. Noureddin {Thaumantis Noureddin, Westwood, Gen. D. Lep-

Genus THAURIA. 



Imago. — Male. Wings short, broad, robust. Forewing with the posterior 

 margin convex towards the base ; cell very broad, short ; first subcostal branch 

 slightly touching the costal near its end ; lower and middle median veinlets nearer 

 together and at equal distances from end of the cell. Hindiving ovate ; anterior 

 margin convex, exterior margin broadly scalloped ; first subcostal branch emitted at 

 two-thirds from the base, the second at three-thirds ; the radial starting from below 

 the second subcostal at a short distance from its base ; the cell open ; the upper 

 median much arched from its base ; a large irregular-shaped glandular patch of black 

 scales extending from near the costal vein to beyond the base of subcostal and upper 

 area of the cell, this patch being overlapped by an out-spreading tuft of long hairs 

 arising from base of the cell ; the lower cell-area and the base of the wino- to the 

 submedian vein also being clothed with long hairs ; a pale yelloiv glandular pouch 

 between the submedian and the internal vein near the middle, the pouch enclosing a tuft 

 of short brown radiating hairs. On the underside of the forewing is a lengthened dull 

 silvery-patch of scales below the base of the submedian vein. Body very robust • 

 thorax very woolly: abdomen above clothed with long woolly tufts and laterally
