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 antennae in both are darker than the 

 colour of the head, their second and third joints are small and equal ; 

 the thorax is biforeolate ; the elytra may be described as very finely 

 rugose with more or less distinct longitudinal costse, 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 tibife 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. 



DiABROTICA SEPARATA, Baly. 



A single specimen from Caracas. 



Neobrotica inconstans, n. sp. 



Obscure fulvous ; the head, basal joints of the antennae, breast, 

 and the tibia and tarsi, black ; thorax with a deej) 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 ; antennae more than half the length 

 of the body, black, the three apical joints (the apex of the terminal 

 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 tibiae and tarsi black ; claws appendiculate. 



Colonia Tovar. 



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, u. sp. 



Pale testaceous, the vertex and the intermediate joints of the
