long one. The length varies from 6-10} mm.

Four specimens, agreeing with an example of Z. affinis, Dej., from Brazil, in 
the British Museum. They are narrower than Z. meaxicana, and have two oblique 
whitish streaks near the hind angles of the prothorax; the black patch on the 
elytra smaller, rounded or subquadrate, and preceded and followed by a white 
spot; and the legs in great part ferruginous. The male-characters are similar, 
except that the anterior tarsi want the projecting hairs. According to Desbrochers 
(Ann. Soc. Ent. Belg. xxxv. p. 42), Z. submaculata, Boh. (affinis, Dej.), is a variety of 
the same species, 
7. Gygops maculiventris, sp.n. (Tab. Il. figg. 17, 17a, ¢.) 
Oblong, rather broad, flattened above, piceous, the antennz and tarsi obscure ferruginous, the tibie with 
a very broad flavo-testaceous annulus near the apex, the vestiture close and fine; the head with an 
ochreous line around the eyes; the prothorax cinereous at the sides and down the middle, becoming 
fulvous towards the apex, and with a large, subtriangular, anteriorly excised, fuscous patch on the 
posterior portion of the disc; the rest of the upper surface mottled with brownish-black and flavo- 
cinereous, the elytra with a sharply-defined yellowish spot at the sides beyond the middle and another 
in a line with it near the apex; the vestiture of the under surface dense, whitish-ochreous, sharply 
maculated with black—a broad, curved, irregular stripe on the flanks of the prothorax (visible as two 
spots from above), a small spot on the mesothoracic epimera, a large patch on the sides of the meta- 
sternum (not extending on to the episterna), and four large spots on the abdomen,—that of the legs 
ochreous or flavo-cinereous, the femora each with a blackish patch. Eyes very large, narrowly 
separated ; rostrum arcuate, tricarinate and quadrisulcate at the base; joint 2 of the funiculus nearly 
twice as long as 3. Prothorax transverse, rounded at the sides anteriorly, strongly bisinuate at the 
base ; densely, minutely punctate. Elytra moderately long, a little wider than the prothorax, obtuse 
at the apex, transversely depressed below the base; finely punctate-striate, the interstices densely 
punctulate, 1 and 5 sparsely granulate, 1 swollen at the base and 5 slightly raised. Ventral segments 
1 and 2 depressed down the middle, the depressed space on 2 densely clothed with erect yellowish 
hairs. Femora each with a single sharp tooth, the posterior pair reaching beyond the apex of the 
abdomen. Posterior tibie sharply mucronate at the inner apical angle. Anterior tarsi without 
projecting hairs.

Two males. A remarkably distinct species, nearly allied to Z. mevicana; but 
differing from it in the nigro-maculate flanks of the prothorax, the subtriangular 
dark patch on its disc, the absence of white spots on the upper surface, 
unidentate femora, the flavo-annulate tibie, &c.
