288 MR. M. JACOBY ON COLEOPTERA [May 21, 
Length 24-3 lines. 
Of rather flattened shape, entirely black ; the head with a longi- 
tudinal central ridge, finely rugose, the clypeus and the base of the 
antennze fulvous or testaceous ; antennee scarcely half the length of 
the body, black, the three (in one specimen the last joint only) apical 
joints fulvous, the third the longest, the intermediate joints slightly 
flattened and widened, closely pubescent: thorax transverse, rather 
more than twice as broad as long, the sides straight, more or less 
sinuate or concave at the middle, causing one or two obscure angles, 
the posterior margins straight ; the surface very obsoletely trans- 
versely depressed near the base and more broadly at the sides, entirely 
finely rugose, opaque, the sides furnished with some very minute 
fulvous hairs; scutellum broad, its apex truncate; elytra very 
slightly widened posteriorly, the apex rounded, the entire surface 
finely rugose, black, opaque, with more or less distinct light reflections 
in the shape of narrow longitudinal bands at the sides ; underside and 
legs black, the coxze obscure fulvous ; tibize unarmed, the first joint of 
the posterior tarsi scarcely longer than the second; claws bifid ; 
anterior coxal cavities open.

SCHEMATIZA VENEZUELENSIS, 0. Sp. 
Black ; the lower part of the face and the apical three joints of 
the antennz fulvous; above fuscous or black, finely rugose, the 
sides of the thorax broadly, and a narrow lateral stripe of the elytra 
obscure flavous. 
Length 3 lines. 
Head finely rugose at the vertex, the portion below the eyes and 
the clypevs fulvous; labrum and jaws black, shining; antennee 
rather more than half the length of the body, black, the two or three 
terminal joints fulvous or testaceous, the third joint very long, longer 
than the two preceding joints together, the intermediate ones 
slightly dilated and pubescent ; thorax more than twice as broad as 
long, the sides rounded, the angles with a small tubercle, the surface 
depressed at the sides, without other grooves, finely rugose, black, 
the sides broadly pale flavous, the flavous portion narrowed at the 
base; elytra finely rugose, the apex rounded, the lateral margin 
from the base to the apex narrowly flavous ; underside and legs 
black, the base of the femora flavous. 
From San Esteban and Colonia Tovar. 
In this species the third joint of the antenne is very long and 
slender, differing in that respect from all the other species of the 
genus with which I am acquainted, the dilatation of the intermediate 
joints is also but feebly indicated ; but as I cannot find any other 
different structural characters I have provisionally placed this insect 
in Schematiza. 
SCHEMATIZA UNISTRIATA, Nl. Sp. 
Obscure fuscous, sericeous ; the lower part of the face and thorax
