lateral process of each side slightly notched, distal lobe very 
much larger than proximal; ventral margin convex, apical 
margin deflexed, in profile minutely excavated. 
Described from a single male taken at 1,000-2,000 ft., San 
Jose de las Matas, Dominican Republic (June, 1938), by P. J. 
Darlington. This species is distinguished by the shape of the 
male genitalia and by the coloration. 
Atopocixius major sp. nov.

Male. Length, 2.0 mm.; tegmen, 2.5 mm. 
Female. Length, 2.2 mm.; tegmen, 2.7 mm. 
Frons, except on lateral margins distally, clypeus, sides of 
head before eyes, lateral fields of pronotum, mesonotum, except 
on margins and scutellum, tegulse, pro- and meso-coxae, basal 
two-thirds of postfemora, and abdomen piceous; vertex, lateral 
margins of frons distally, gense, rostrum, upper surface of pro- 
notum, mesothoracic pleurites below tegulse, tip of scutellum 
and legs, except basal part of postfemora, sulphur yellow; mar- 
gins of mesonotum reddish brown; membrane of abdomen red. 
Tegmina fuscous; a spot covering apex of costal and base of 
first subapical cells, middle and distal areas of apical cells from 
stigma to M2, a small spot overlying M cross vein in mem- 
brane, and a small area at apex of clavus hyaline; a spot at base 
of stigma and another at base of third apical cell of M dark fus- 
cous; base of tegmen and scutellar margin pallid yellow; veins 
fuscous. Wings hyaline, slightly smoky at base, veins fuscous. 
Anal segment of male short, lateral lobes broad, produced 
distally, not incurved. TEdeagus with periandrium tapering 
distally, somewhat oblique and expanded near apex, the two 
sides together assuming a shallow scoop-like form; dorsal mar- 
gin of each side at apex with three or four minute teeth and a 
short almost horizontal apical spine. Penis slightly curved, 
ventral margin weakly convex, dorsal margin sinuate, sub- 
parallel to near apex, then abruptly decurved to meet ventral 
margin in a short spine directed posteriorly and outward, con- 
tinuing outward curvature of each lateral arm of penis. Genital 
styles in profile rather narrow, dorsal margin slightly convex at 
base, thence strongly concave, dorso-lateral apical process 
deeply excavated, distal protuberance narrowly lobate, much
