The antennae are pectinated. Palpi usually curved, 

 smooth and cylindrical. Tongue moderate, usually as long 

 as the thorax beneath.

GLAUCOPIS FABK. 



Wings most frequently narrow, sometimes ample ; hyaline or 

 limpid, with black borders or tips, and the veins covered with 

 scales. 



In the fore wings the subcostal nervure subdivides into two 

 marginal nervules, a bifid apical branch and a post-apical branch ; 

 the sulcosto-inferior branch is usually the only one proceeding from 

 the disk, when it arises at its posterior-superior angle. Sometimes, 

 however, the disk emits from four to six nervules(?). The median 

 nervure is 4-branched. Hind wings without costal nervure. The 

 subcostal is bifid from the disk, and the discal is without branches 

 to the hind margin. (?) The median is bifid or bifid with the lower 

 branch forked near its tip. 



Head with ocelli. Antennae most frequently bipectinated. 

 Palpi moderate, generally ascending, usually longer than the 

 clypeus. 



Body linear, most generally slender, subcylindrical and more or 

 less metallic. Patagia small. Legs with the tibiae roughened 

 with spines. 



This genus is of considerable extent, and its limits are very 

 undecided. I have only a single specimen belonging to it, and
