bands, one at end of segment 4, another at tip, and another 
midway between; forewings clear except brown in anterior 
basal cell. 
Head not as brown as thorax, strongly declivous, with long, 
sparse pubescence; vertex a little more than half as long as 
broad, anterior portion bent downward, posterior ocelli elevated, 
with a rather deep foveal impression on each side of median 
line, anterior outer corners produced into a short, upturned 
epiphysis over each antennal base. Gense a little swollen beneath 
antennal sockets, bulging slightly forward of vertex. Frons 
wholly visible, broadest at base; clypeus moderately small; ros- 
trum short. Antennae a little longer than width of head, banded 
black and white, second segment with one side of apex produced. 
Thorax broad, strongly arched, sparsely clothed with long 
hairs, mesonotum very short, transverse; pseudonotum (behind 
metanotum) large, long, with a pair of slender, upturned, whitish 
horns between this and basal segment of abdomen. Legs long, 
hind tibiae long, with a very small basal spur and short distal 
spines. Forewings somewhat rectangular, hyaline, veins narrow, 
pterostigma wanting, radius not straight, cubitus unforked. 
Hind wings reaching about to primary fork of basal vein, veins 
practically wanting. 
Abdomen short (genitalia mutilated).
