longer than proximal; ventral margin convex, apical margin 
deflexed, lip-like. 
Pregenital plate of female twice as wide as long, subquadrate, 
anterior and posterior margins parallel, lateral margins in ven- 
tral view slightly convex. 
Described from one male and one female taken between 3,000 
and 7,000 ft. in Valle Nuevo, S. E. Constanza, Dominican Re- 
public, by P. J. Darlington (August, 1938). This species is 
distinguished by its size, by the shape of the male genitalia, and 
by the coloration. 
Lomagenes gen. nov. 
Head with eyes scarcely two-thirds width of pronotum. Ver- 
tex as long as wide, lateral margins expanding to base, which is 
shallowly emarginate; anteriorly a broad transverse ill-defined 
ridge or obsolete carina separating vertex from frons; about 
midway between this and base a prominent transverse carina, 
angulate at middle with apex cephalad, with a median carina 
passing forward from it to curve on to frons; vertex basad of 
this angulate carina depressed, the depressed part being two 
and a half times as wide as long. Frons longer than its widest 
part (1.4 to 1), base slightly more than half as wide as apex, 
lateral margins sinuately expanding to three-quarters from base 
then curving inward to suture; median carina distinct, lateral 
margins carinate, slightly raised. Clypeus at base three-quarters 
as wide as widest part of frons, tapering acutely to apex; median 
carina absent, lateral margins carinate; clypeus and apical half 
of frons only slightly convex in profile, suture impressed, frons 
at base subangularly rounded into vertex; no median ocellus, 
genae rather tumid below antennae; no subantennal process; an- 
tennae with basal segment very short, second segment slightly 
longer than broad; eyes widely emarginate ventrally. Pronotum 
as long as vertex, anterior margin medially convex, shallowly 
emarginate behind eyes, posterior border shallowly emarginate, 
curving anteriorly at sides; median carina distinct, lateral ca- 
rinae of disc obsolete or absent, lateral margins strongly carinate 
between eyes and tegulae; mesonotum feebly convex, distinctly 
tricarinate, scutellar area depressed, tip of scutellum acute. 
Hind tibiae unarmed. 
Tegmina with sides expanding apically for two-thirds of
