onymy. 
Description. Face short, hardly extending ventrad of eyes; an- 
terior vertex tubercle transverse, confluent with well-demarked lateral 
tubercles; vertex and area behind eyes inflated. Scape length equals 
about 4/5 eye diameter; flagellum stout, segments short, wide. Mouth- 
parts sunken into ventral concavity of head, mandibles nearly vestigial, 
maxillae and labium greatly reduced. Pronotum transverse, arched, 
lightly sclerotized, two transverse furrows. Trichobothrial setae 
present at apex of abdomen but callus eerci poorly delimited. 
Male (figs. 20, 21, 22) : ninth tergite and ectoprocts fused, ninth 
sternite a narrow band, tenth sternite absent. Gonarcus desclerotized 
medially, articulated laterally to apodemes of ninth tergite. Gono- 
coxites articulated to gonarcus arms laterally ; space between gonarcus 
and gonocoxites weakly desclerotized dorsally. Rectangular median 
sclerite extending from gonarcus to mediuncus pouch. Mediuncus 
withdrawn and coiled in deep pouch, bearing lateral arms and long 
terminal setae. 
Female (figs. 23, 24) : 7th sternite large, desclerotized postero- 
medially and weakened along ventral midline. Eighth sternite band- 
like. Ninth tergite discernible but fused with ectoprocts. Ninth 
gonocoxites with hypocaudae represented by short tubercles. Ninth 
gonapophyses developed as short projections from posteromedial sur- 
faces of ninth gonocoxites, inserted into transverse, cup-like eighth 
gonocoxites to close genital chamber. Copulatory bursa large, mem- 
branous, widely confluent with genital chamber. Spermathecal duct 
short, membranous. Spermatheca with a thin-walled, saccate, expan- 
sible posterior diverticulum and a short, tubular anterior extension 
which is convoluted and weakly sclerotized. 
Forewing (fig. 25) : elongate, apical and posterior edges straight 
(?) or concave (c?). Recurrent humeral vein present; Sc apically 
connected to R by a crossvein; base of M distinct from R, fusing 
for a distance beginning at level of recurrent humeral vein. Inner 
gradate series well-developed; outer series sometimes absent. Hind- 
wing: Sc connected to R by a crossvein; recurrent humeral vein 
present; MA branches from the stem of M and fuses with R basad 
of level of recurrent vein (difficult to see, because of the proximity of 
M and R, basally) ; stem of MP not fused with R basally. Vestige
