pedicel nearly one half of its length, third fork very short pedicellate; discal

Hydromanicus extremus, sp. nov. 



Type.— M. C. Z. 10,888. Borneo: Telang (Grabowsky). 



Dark; clothed with yellowish hair, on head and thorax mostly golden 

 yellow; antennae pale yellowish, not annulate. Fore wdngs with yellowish 

 hair, densely marmorate with pale brown, the largest mark is one near costa 

 before stigma; hind wings faintly fumose near tip, the veins brownish. In 

 fore wings the discal cell is of moderate length, about one half of third sector; 

 first fork with a pedicel one half of fork, second fork reaches discal cell, third 

 fork with a pedicel more than one half of fork, end of median cell is as far out 

 as end of discal cell. In the hind wings the curvature of the subcosta and 

 radius is extreme, so that in bending back they touch the discal cell, the radius 

 apparently uniting with the radial sector for a short distance, and before that 

 the radius and subcosta are almost united for a long distance.

 The lower appendages of the male genitalia are long, slender, upcurved, the 

 reddish chitinous pieces each side of the superior median plate are deeply
