strongly depressed, the entire surface sparsely clothed witii short 

 yellow pubescence. 



Type. — Para, Brazil. (Baker.) Length 5 nun. 



Clypeus broadly transversely depressed, with fairly well defined sides, and 

 frontal ridge which forms a point between the antennae, front with longitudinal 

 fovea, tubercles obsolete, surface closely punctate; antennae filiform, but 

 rather stout reaching about the middle of the elytra, entirely black except the 

 scape and extreme base of tlie second joint; thorax strongly angulate, surface 

 nearly equate, thickly and strongly punctate, a short smooth medium carina, 

 the usual median callouses showing obsoletely, somewhat shinj'; elj-tra strongly 

 punctate striate, becoming obsolete at apex, strongly dejjressed at base so that 

 the scutellar region is prominent ; claws appendiculate. 



Near apicicornis Jac, l)ut that species has differently colored 

 antennae and legs, and is stouter and more hirsute, and the 

 elytra are much more strongly punctured. T^'pe unique. 



Hapolotrius plagiatus nov. sp. 



Head black, thorax yello^v, thickly covered with golden pubes- 

 cence, elytra cyaneous blue, with punctures arranged in striate 

 form, the sides and apex clothed in dense golden pubescence, 

 leaving a common, oblong seemingly bare spot, stretching from 

 the base to a little below the middle, legs yellow, the four anterior 

 tibiae and tarsi and apex of posterior femora black. 



Type. — Cachabe, Ecuador; low c; XII, 1896, (Rosenberg). 



Length 5.5 mm. 



Clypeus with a deep transverse groove, somewhat triangular in form, occupy- 

 ing the whole front, making an inverted frontal V fovea, vertex black, rather 

 coarsely punctate and sometimes showing a partial smooth median carina 

 (sexual?); antennae fihform, testaceous, clouded in the middle, thorax trans- 

 verse, sides almost straight like pubescens Clk., faintly obliquely foveate each 

 side behind, all the angles sharp but not prominent. The entire surface 

 yellow, pubescent, except a narrow dark edge adjoining the eh'tra, scutellum 

 black; elytra with strong basal depression, not, however, curved up to the 

 shoulder as strongly as in many but more like a deep sub-basal fovea; the seem- 

 ingly bare spot is sparsely covered with dark hairs which can best be seen from 

 the front (looking to a white background). The intervals occasionally seem 

 to be very finely punctulate, body beneath l)lack, claws appendiculate. 



Six examples seen from the type locality, also three from 

 Paramba (near Cachabe), also one example from Santos Marcos, 

 Bolivia, 2000 m., second Jac. coll., "n.i.Mus. " (rubbed — in poor 

 condition).
