anterior margin obliquely convex in lateral view; face convex, without 
pubescence, muscle impressions distinct or not, transclypeal suture complete 
or obscure for only a short distance medially, clypellus continuing profile of 
clypeus. 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carina rectilinear and horizontal or slightly ob- 
lique, not quite attaining posterior margin of adjacent eye, posterior pronotal 
margin concave, disk of pronotum and posterior portion of scutellum without 
pubescence and nearly always without sculpturing. Forewing usually with 
membrane which includes all of apical cells except base of fourth, occasionally 
including adjoining portion of anteapical cells also, veins distinct or not, not 
elevated, with four apical cells and base of fourth more proximal than base of 
third, without an anteapical plexus of veins, texture usually opaque; wings of 
female at rest exceeding apex of ovipositor. Hindleg with femoral setal for- 
mula 2:1:1, first tarsomere with length greater than combined length of 
second and third, with two rows of very small setae. 
Male genitalia: Pygofer moderately produced, rounded apically, chaetotaxy 
varying interspecifically but with macrosetae never very sparse, often covering 
a considerable portion of disk and rarely with interspersed microsetae, 
processes present or absent, usually apical when present (occasionally ven- 
tral). Plates usually not extending as far posteriorly as pygofer apex, slender, 
triangular, fused basally (exception: EF. ekila, n. sp.), usually narrowed near 
midlength and usually with uniseriate setae. Style quite variable interspeci- 
fically, but almost always extending posteriorly farther than connective, with 
or without a preapical lobe. Connective narrow, linear or Y-shaped, with or 
without a median keel. Aedeagus quite variable interspecifically, not ar- 
ticulated with connective. Paraphyses usually present and variable interspeci- 
fically. 
Female abdominal sternum VII greatly variable interspecifically, posterior 
margin transverse, or (more often) emarginate, not produced medially. 
Genital chamber usually with sclerites in the membrane. Ovipositor with first 
valvulae with or without processes that are variable interspecifically when pre- 
sent; second valvulae broadened in all or most of portion beyond basal curva- 
ture, the primaries often with minute secondary denticles, with posteroventral 
anteapical denticles. Pygofer with macrosetae arranged more of less uniform- 
ly over disk, or anteapically and parallel to posteroventral margin. 
Color of dorsum from pale red to deep red or black, usually marked with 
yellow. 
Erythrogonia has been revised recently (1963a) by Medler who recognized 63 
species and one subspecies. Because of the availability of this work, it is un- 
necessary to publish a key to species, or to repeat illustrations in the present 
work. Medler stated that host plants of species of Erythrogonia included 
banana, Croton, cotton, Citrus, Lantana camara L., and Conostegia lanceolata 
Cogniaux. Medler’s illustrations of the forewings show an unexpected amount 
of variation in the anteapical cells, which are fairly constant in other genera. 
This resulted partly front the texture of the forewing in the region of the bases 
of these cells, a region where the venation is very difficult to see, and perhaps
