also been examined by Mr. Baly) are of pale flavous colour and differ 
in several particulars from Erichson’s description: in one specimen 
the labrum is piceous ; the antennz in both are darker than the 
colour of the head, their second and third joints are small and equal ; 
the thorax is bifoveolate ; the elytra may be described as very finely 
rugose with more or less distinct longitudinal costee, especially 
strongly marked at the sides ; the base, a transverse spot at the middle, 
and another below the latter are pale fulvous, scarcely visible in one of 
the specimens ; the underside and legs are pale flavous, with the outer 
margin of the tibize and the tarsi darker. It is possible that these 
Venezuelan specimens are distinct from, although closely allied to, 
Erichson’s species, or that they are but local varieties. 
DiaBROTICA CLYPEATA, Baly. 
Colonia Tovar. Two specimens. 
D1aBrorica SEPARATA, Baly. 
A single specimen from Caracas. 
NEOBROTICA INCONSTANS, 0. Sp. 
Obscure fulvous; the head, basal joints of the antenne, breast, 
and the tibia and tarsi, black; thorax with a deep transverse groove ; 
elytra finely punctured, each with an elongate subangular black mark 
at the shoulder and an obscure piceous spot below the middle. 
Var. Elytra immaculate. 
Length 3 lines. 
Head broader than long, impunctate, black (the extreme vertex 
sometimes testaceous), with a distinct fovea between the eyes; the 
frontal elevations not defined ; antennz more than half the length 
of the body, black, the three apical joints (the apex of the ferminal 
joint excepted) pale flavous, the first joint very long and slender, 
the second very short, the following elongate and nearly equal ; 
thorax twice as broad as long, the sides rounded and widened before 
the middle; the disk deeply transversely grooved, impunctate, with the 
exception of some very fine punctures near the anterior angles ; 
scutellum impunctate ; elytra finely and closely punctured, the in- 
terstices in the male slightly rugose, pale fulvous, the shoulders with 
a short, narrow, elongate and angulate black mark, the lower angle 
of which turns inwards, and a round piceous obscure spot below the 
middle; breast and the tibiee and tarsi black ; claws appendiculate.

N. inconstans rather closely resembles N. pallescens, Jac., from 
Honduras, but differs in the want of the longitudinal sulcations of 
the elytra and in the presence of the elytral black markings. The 
species is probably subject to a good deal of variation, and in the 
variety the left elytron is pale green and the right one fulvous, 
neither of them having any markings. 
NEOBROTICA DIMIDIATICORNIS, li. sp. 
Pale testaceous, the vertex and the intermediate joints of the
