428 MR. MARTIN JACOBY ON NEW SPECIES [ Nov. 28, 
the breast piceous; thorax impunctate; elytra subdepressed, 
extremely closely and finely punctured, the basal margin, a narrow 
transverse band below the middle, and two spots near the scutellum 
dark brown. 
Length 7 millim. 
Head impunctate, testaceous, the frontal elevations rather 
feeble ; eyes large, the intermediate space not wider than the width 
of each eye; antennz with the basal three or four joints and the 
apical one testaceous, the rest blackish; thorax short and trans- 
verse, the sides broadly flattened, the anterior angles dentiform ; 
the disc impunctate, testaceous, feebly transversely suleate near 
the base ; scutellum testaceous; elytra widened towards the apex, 
rather flat, extremely finely and closely punctured, testaceous, the 
extreme basal margin, a small spot near the scutellum, and a 
narrow transverse, slightly convex band, immediately below the 
middle, piceous or dark fulvous; legs testaceous; breast and 
abdomen piceous. 
Hab. Pichinché, Colombia (Rosenberg). 
Of this species I have five exactly similar specimens before me. 
The design of the elytra differs from that of any other species 
Tam acquainted with except O. tenwicineta Jac., which is a dif- 
ferently shaped insect, with a different thorax, very narrow elytral 
bands, and of black colour. This species is also known from Mexico. 
OEDIONYCHIS DIVERSA, Sp. 1. 
Testaceous, the apical joints of the antenn (except the last) 
and the breast black; thorax impunctate ; elytra elongate, finely 
punctured, each with two spots at the base, one at the middle, and 
a transverse band near the apex, black. 
Var. The apical band divided into two spots. 
Length 5 millim. 
Head impunctate, deeply foveolate between the eyes, the latter 
very large; antennz with the lower five and the apical joint testa- 
ceous, the others black, third and fourth joints equal, elongate, 
the terminal joints rather shorter; thorax about twice and a half 
broader than long, the sides broadly flattened, the lateral margins 
strongly rounded anteriorly, the anterior angles thickened but 
not produced, the surface impunctate, rather convex; scutellum 
black; elytra elongate, nearly parallel, very minutely punctured, 
testaceous, a small spot on the shoulders, another nearthe scutellum, 
a third at the middle, and a transverse band near the apex, not 
quite extending to either margin, black; legs and abdomen testa- 
ceous, breast black. 
Hab. St. Catharina, Rio Janeiro, Brazil. 
A somewhat elongate species, principally distinguished from 
those with similar elytral spots by the additional black subapical 
band and the black breast, colour of the antenne, &e.
