impunctate, the anterior angles not produced; elytra finely 
punctured anteriorly, a sutural pear-shaped spot below the 
scutellum and a transverse band below the middle bluish-black ; 
breast black. 
Length 5 millim. 
Head impunctate, deeply foveolate between the eyes, the latter 
rather closely approached ; antenne with the lower four joints 
fulvous, the rest piceous, the joints comparatively short ; thorax 
about twice as broad as long, the sides feebly rounded and 
narrowed anteriorly, the anterior angles thickened and not pro- 
duced, the sides broadly flattened, the dise impunctate; scutellum 
black ; elytra very finely punctured, except near the base and 
within the humeral depression, where the punctuation is stronger, 
the ground-colour testaceous, a sutural spot below the scutellum 
and an irregular narrow transverse band below the middle bluish- 
black, sometimes piceous; the breast black, the abdomen and legs 
testaceous. 
Hab. Espirito Santo, Brazil. 
Two exactly similarly coloured specimens of this species are 
before me; the design of the elytra differs from that of any other 
Oedionychis, and the general size of the insect is comparatively 
small, 
OEDIONYCHIS VENEZUELENSIS, Sp. Nn. 
Flavous, the apical joints of the antennz piceous; head with 
two black bands; thorax fulvous, impunctate; elytra extremely 
minutely punctured, with a spot at the shoulders, another near 
the scutellum, a transverse band before and another below the 
middle, black. 
Length 6 millim. 
Of somewhat flattened, posteriorly slightly widened shape ; the 
head with a few punctures near the eyes, the latter very large, the 
diameter of each distinctly wider than the intermediate space; 
the vertex flavous, with a black stripe at each side, the space 
between the antennz strongly convex in shape of a ridge, black ; 
the palpi flavous; antennz slender, the lower three joints flavous, 
the others blackish, third joint slightly shorter than the fourth ; 
thorax not more than twice as broad as long, the sides nearly 
straight and slightly narrowed anteriorly, broadly flattened, the 
anterior angles thickened but scarcely produced, the dise impunc- 
tate, fulvous, the flattened portion flavous, the base with an 
obsolete transverse sulcus ; scutellum flavous ; elytra scarcely per- 
ceptibly punctured, flavous, the shoulders with a short, thick 
black spot, another one of more elongate shape is placed near the 
scutellum, a transverse, medially constricted black band is situated 
before and a second one below the middle; the under side and 
legs are flavous; metatarsus and claw-joint typical. 
Hab. Venezuela. 
Differs in the coloration of the head and the position of the 
elytral markings from any other species.
