marks on several segments near the base; legs pale. Wings with 

 green venation; in fore wings the gradates, many costals, origin of 

 radial sector, and cross-vein to median, the divisory and bases of 

 second, third, and some other cubital cells wholly black; radials in 

 part, and origin of branches of the radial sector, and most of the 

 marginal forks in part, black. In the hind wings the gradates, and 

 part of marginal forks dark; stigma not distinct in either pair. Wings 

 large and broad, hind wings acute at tip; gradates subparallel, inner 

 (of seven or eight) scarcely nearer to the radial sector than to the 

 outer (of six or eight), the veinlets not much disjointed; third cubital 

 cell of moderate length, tip oblique; marginal forks over three times 

 as long as broad; 20 costals before stigma in fore wing. Pronotum 

 rather longer than broad, tapering in front. 

 Expanse 44 mm. 



LEUCOCHRYSA MINIMA, sp. nov. 



Type M. C. Z. 10,061. Colombia: Caldras, 4,400 ft., May. 

 H. S. Parish. Three specimens. 



Pale yellowish; face, palpi, and antennae unmarked, no marks 

 on pronotum or rest of thorax; wings with green venation; in fore 

 wings the radial sector in part, the gradates, some of the costals, the 

 radials in part, and sometimes parts of other veinlets, dark; in hind 

 wings the gradates are dark; stigma dark green, in hind wings with 

 brown spot at the base. Wings rather long, in hind pair acute at tip; 

 gradates subparallel, five in inner, six in outer series, veinlets widely 

 separated, the inner series much closer to the radial sector than to 

 the outer series; marginal forks two and one half times as long as 

 broad, 16 costals before stigma, divisory arising very near to cubitus, 

 third cubital cell not very long, wide at tip. Pronotum much broader 

 than long.
