hinder fovea ill-defined. Elytra minutely punctured, strongly 

 plicate below the humeral callus. 



H. von Harold describes the thorax as being bifoveo- 

 late ; the third fovea is less distinctly impressed and 

 probably in some specimens entirely obsolete.

Hah. Brazil. Unique in my own collection. 



The present species differs from the preceding in its 

 non-foveolate thorax and in the entirely black legs and 

 antennas.

Head not broader than long, subrotundate ; clypeus with the 

 longitudinal ridge distinct, but not strongly elevated ; antennae 

 three-fourths the length of the body, black, the second joint short ; 

 the third distinctly longer than the second, the fourth as long as 

 the preceding two united. Thorax one-half broader than long ; 

 sides subangulate just behind the middle, faintly sinuate posteriorly, 

 slightly converging towards the apex in front ; above convex, 

 deeply impressed on either side with a large round fovea ; disk 

 with two large black patches, which are confluent on the medial 

 line. Elytra oblong, slightly dilated posteriorly, their apices 

 regularly rounded ; above convex, distinctly punctured, the punc- 

 tures on the anterior disk obsoletely arranged in strife ; sub- 

 humeral callus very slightly raised, ill-defined ; each elytron with 

 the narrow outer limb, a sutural line, which, extending from the 

 apical angle to a short distance above the middle of the elytron, 

 from thence runs obliquely outwards to the basal margin just 

 within the humeral callus, yellowish white ; in addition are two
