ending in hind margin, divisory veinlet, base of radial sector, upper 

 side of second cubital cell partly, and bases of branches of radial 

 sector black. Hind wings with costals and some other cross-veins 

 partly black; stigma in both wings long, deep green. Pronotum 

 much broader than long, narrowed in front. Wings not very 

 broad, acute at tips, two or three inner gradates, four or five outer 

 ones, inner series much nearer to outer than to radial sector; mar- 

 ginal forks hardly twice as long as broad; divisory veinlet ends 

 beyond the cross-vein; second cubital cell much narrower than the 

 third. Expanse 24 mm.

Leucochrysa luctuosa, n. sp. 



Face with large spot on clypeus and triangular spot under each 

 antenna reddish, vertex with an irregular red stripe each side; palpi 

 unmarked; basal joint of antennae with broad red stripe on outer 

 side, about 20 of next joints with black on inner side; pronotum 

 with red stripe on each side (not marginal) more approximate be- 

 hind the furrow; thorax with red spots each side in front, two on 

 each scutellum, and mark over base of hind wings; basal abdominal 

 segments with red mark each side. Wings with greenish venation, 

 base of radial sector and a portion toward stigma with its branches 

 each side partly black; many costals at margin black, two or three 

 radial cross- veins near base are black in middle; the base ot second 

 cubital cell, and part of third, and a few anals near by are black 

 gradates pale; hind wings with radial sector black near stigma, not 

 at base, outer hind margin blackish for a long distance; stigma 

 in both pairs black at base. In fore wings the inner gradates extend 

 basally, so there are about 15 or 16 of them, 12 in the outer series, 

 the two series farther apart in middle than at either end; radial 

 sector sinuous.
