Pearman’s description (1933) is augmented as follows: Measure- 
ments (Table II). Lateral prongs of hypandrium joined along 
their length to sides of hypandrium by semimembranous cuticle. 
Female epiproct (Fig. 15) with postero-lateral sclerotized strips 
turning slightly outward at their distal ends. 
Material examined. — Brazil: Goias: Jatai, October, 1972 1 $ 
F. M. Oliveira; 20 Km. north of Sao Joao da Alianca, April 14, 
1956, 1 cT , 13 $, F. S. Truxal. 
Eremopsocus crassicornis (Kolbe), new combination 
Cerastis crassicornis Kolbe, 1883: 70. 
Cerastipsocus crassicornis (Kolbe), Smithers, 1967: 96. 
Diagnosis. — See diagnosis of E. nigripes n. sp. 
Male. — Measurements (Table II). 
Morphology. — Antenna with basal flagellomere (Fig. 6) decid- 
edly incrassate, second less so, third slightly incrassate basally; all 
flagellomeres densely beset with upright hairs. Compound eyes small 
(see Table II). Hypandrium (Fig. 3) with pair of short distal 
prongs; these and distal ends of lateral thickenings beset with minute 
denticles. Discal lobe and regions to its sides and base bearing setae. 
Phallosome (Fig. 4) a closed ring with truncate distal process, the 
process and weakly-sclerotized region to its sides bearing minute 
denticles. Paraproct (Fig. 5) with a long distal spur and a short 
spur distad of sense cushion. Epiproct and posterior clunial margin 
as in Fig. 5. 
Color (in alcohol). — Compound eyes and inner rims of ocelli 
black. Head deep orange-brown with faint clypeal striations. Maxil- 
lary palpi dark brown. Antennal scape and pedicel dark chestnut 
brown; flagellum black. Mesonotal lobes deep to medium chestnut 
brown, their borders and thoracic pleura orange-brown. Forewing 
membrane ( Fig. 1 ) uniformly fumose-brown except colorless in 
base of areola postica and nearly so in basal region of cell Ri from 
behind stigmasac nearly to apex of pterostigma. Pterostigma brown
