punctate, with two small black spots; elytra minutely punctured 
at the base only, a spot on the shoulders, another near the 
scutellum, and the posterior half black. 
Var. The thoracic and elytral spots absent. 
Length 6 millim. 
Head impunctate, flavous; eyes large, each as broad as the 
intermediate space, frontal elevations transverse; antennze with 
the lower joints flavous, the terminal ones more or less black ; 
thorax twice as broad as long, the sides rounded, narrowed in 
front and broadly flattened, anterior angles pointed, slightly pro- 
duced, the surface impunctate, flavous, with two small back spots 
near the base; elytra nearly impunctate, except near the base, 
where there are a few minute punctures, flavous, a spot near the 
scutellum and one on the shoulders, as well as almost the whole 
posterior portion, black, but this colour not quite extending to the 
apex; under side and legs flavous; prosternum convex between 
the cox; metatarsus very short, claw-joint strongly swollen. 
Hab. Peru. 
Of this species I possess two specimens, in one of which some 
obsolete additional thoracic spots are present and the elytral ones 
absent, the shape of the posterior black portion is regular; in the 
other the anterior edge is deeply sinuate, but other differences I 
cannot find. 
OEDIONYCHIS VARIATA, Sp. 0. 
Obscure piceous below, above testaceous ; thorax impunctate: 
elytra subdepressed, extremely minutely punctured, the basal 
margin, a spot on the shoulders, another oblique spot near the 
scutellum, a transverse narrow band at the middle, and another 
spot near the apex, black. 
Length 7 millim. 
Head impunctate, the frontal elevations feebly raised, carina 
short and convex; antenne fulvous, the third joint shorter than 
the fourth (2) or equal (¢); thorax with broadly flattened sides, 
the lateral margins nearly straight, obliquely narrowed anteriorly, 
the dise rather flat, impunctate, testaceous, the anterior angles 
in shape of a small tooth; elytra evenly rounded and widened 
at the middle, broadly margined, scarcely perceptibly punc- 
tured, testaceous, the extreme basal margin, connected with 
an elongate spot which covers the shoulders, an oblique comma- 
like spot near the scutellum, a narrow transverse band (somewhat 
angulate near the lateral margin) at the middle, and another 
transverse spot near the apex, black ; below and the legs testaceous. 
Hab. Bolivia. 
Well distinguished by the shape and the position of the elytral 
spots.
