simple. Since this group appears to be a sizable as well as 
homogeneous one and confined to the West Indies, I am pro- 
posing for it the generic name Homoschema , from 6/xo<? the same , 
and o-x^/xa (to) outward appearance. The type of the genus is 
H. ornatum. 
Description of the Genus 
From 2— d mm. in length, oblong oval, widened posteriorly in 
female, moderately convex, often impunctate and at most very 
finely and confusedly punctate, lustrous reddish or yellowish 
with violaceous or blue-green elytra. 
Antennae longer than half the body, always pale, rather 
stout; first joint long, 2nd short, both swollen, 3rd longer 
than 2nd, dth longer than 3rd, the rest more or less subequal, 
gradually shortening a little. Head with distinctly marked 
frontal tubercles and an impressed line of punctures running 
up to the large fovea near the upper part of eye, a few scattered 
punctures usually in the space between eye and antennal sockets. 
Space between antennal sockets variable, in some narrower spe- 
cies a slightly elevated line gradually vanishing in the lower 
front, in other wider species, a broad, more convex carina that 
spreads out down the lower front with a depression on either 
side below the antennal sockets, this interantennal area very 
useful in identification as to the group but not to the species 
of the genus. Thorax considerably wider than long but never 
twice as wide, with curved and margined sides, and oblique 
angles anteriorly and almost straight basal margin ; moderately 
convex without depressions, except in one species ; surface 
usually mirror-smooth, sometimes very finely punctate. Seutel- 
lum large, triangular, and usually but not in all species, palely 
conspicuous in the dark violaceous elytra. The elytra often 
mirror-smooth or very finely and confusedly punctate, wider 
than the prothorax, convex, with a transverse depression below 
the humeri, the female usually slightly wider posteriorly. Be- 
neath, the epipleura wide but disappearing at the apical angle. 
Body beneath usually pale, in a few species the breast and abdo- 
men, and, in these cases, the scutellum too, dark. Legs and 
antennae always pale. Anterior coxal cavities open. Legs rather
