HOLCOCEBA new gen. 
Hind wings slightly excised along the costa. Subcostal vein simple, 
attenuated towards the base. The discal vein is oblique, and gives off 
two branches, one central, the other a curved medio-discal branch. 
jVIedian vein three-branched, the two superior branches arising from a 
short common stalk. The submedian distinct. 
Forewings elongate-lanceolate. At the discal third of the wing the 
subcostal vein sends off a marginal branch, and at the end of the disc, 
two others to the costa behind the tip and a furcate apical branch near 
its end, the lower branch running into the apex of the wing. Beneath 
the apical are five nervules the posterior two of the median vein arising 
close together. The submedian forked at the base. 
Flead large, smooth, with hairlike scales. Face broad, not tapering, 
rounded. No ocelli. Antennae about one-half as long as the fore 
wings; basal joint in the % , ciliated in front, rather long, flattened, 
concave within, articulates with the stalk by means of a nodule, at the 
junction of which with the stalk, it is sharpig excised and the stalk 
beneath, miscroscopically pubescent; in the 9 the basal joint is long, 
cylindrical, stalk scarcely pubescent beneath. Labial palpi cylindrical, 
ascending equal to the vertex, rather widely separated; second joint 
slightly thickened beneath with scales, rather longer than the terminal; 
terminal joint, slenderer than the second, smooth and pointed. Maxil¬ 
lary palpi very short. Tongue scaled at the base, as long as the thorax 
beneath. 
The perfect insects bear some resemblance to those of the genus 
G-elechia; they are sluggish in their motions and flight.
