Characters. — Head small, roundish, flattened on the fore part, situated deep on the thorax; 
front broad; eyes ovate, a little emarginate on the inside above; ocelli arranged in a curved line on the 
front, the middle one very small; palpi prominent, incurved, four jointed, first and second joint small, 
of about equal thickness and length, third joint almost cylindrical, more slender than the first and 
second, almost as long as these two joints taken together, fourth joint cyhndrical, very slender, longer 
than the first three taken together; antennae projecting forward, longer than the head and thorax taken 
together, 2+14 jointed; joints of the scapus distinctly set off, cupuliform, not setiferous at the apex, 
flagellar joints cylindrical, with a downy pubescence. Thorax oval, highly arched; scutellum small, 
almost semicircular ; metathorax steep. Abdomen long with seven segments, in the male cylindrical, 
with a moderate anal joint, and small forceps. Legs slender, hind tibiae spurred, with few very small 
spines along the outer side. Wings oblong-oval, moderately rounded at the base, longer than the abdo- 
men, microscopically pubescent. Subcostal vein complete, joining the costa immediately before the apex 
of the small cell Rj or but slightly beyond it, costal vein extending a little beyond the tip of R4-1-5 and 
not reaching the apex of the wing; basal cell R short, much widened toward the apex ; small cell almost 
equilateral, its base situated immediately beyond the base of the fork of the media; the media almost 
sessile, both branches of the fork bending posteriorly towards their tip ; fork of the cubitus far distad of 
the fork of the media; anal vein incomplete, not reaching as far as the fork of the cubitus (PI. 3, Fig. 30).

Characters. — In this fossil genus, the subcostal vein seems to be entirely wanting, while the 
base of the radial sector is quite oblique differing in this respect from most of the Sciophilinae which 
have this portion of the radial sector nearly erect. Ri ends beyond the middle of the wing; cell Rj is
