Elytral striae unusually coarse and distinctly impressed. 



Prothorax short and transverse, the sides parallel in basal half. 



37 sobrinus 

 Prothorax longer, the sides convergent from the basal angles. 



38 11 oriel a n u s 



2© — Body rather strongly convex 21 



Body distinctly depressed 22 



21 — Prothorax shorter, not less than one-half wider than long. 



Eyes separated by scarcely two-thirds of their own width... 39 COnfertllS 

 Eyes separated by distinctly more than two-thirds of their width. 

 Elytral punctuation a little sparser, similar to that of confertus. 



40 f iisculus 

 Elytral punctuation excessively dense, similar to that of punctatissimus. 



41 macer 

 Prothorax unusually long, but slightly more than one- third wider than long; 



elytral punctuation excessively dense 42 indlltUS 



22 — Antennae very short, the intermediate joints barely longer than wide. 



43 punctatissimus 

 Antennae longer, the joints distinctly longer than wide. 



Elytral striae rather coarse and distinct, the punctures of the intervals 



moderately fine and unusually strong 44 deplanatllS 



Elytral striae exceedingly fine, feebly impressed, the punctures of the inter- 

 vals fine and much sparser 45 gemellus 



23 — Strongly polished and pale flavo-testaceous throughout.

1 H. humeralis Lee. — N. Spec. Col., 1866, p. 135. — Elongate-oval, 

 moderately convex, polished, piceous-black throughout ; antennae fuscous ; 

 legs pale flavate ; each elytron with a large suffused basal pale area ; pubes- 

 cence long, moderately dense, semi-erect, pale and conspicuous. Head feebly 

 convex, rather finely but deeply, somewhat densely punctate throughout, 

 the eyes rather small, separated by one-fourth more than their own width ; 

 antennae somewhat robust, nearly two-fifths as long as the body, the joints 

 feebly obconical, not quite twice as long as wide, the third scarcely as long as 

 the fourth. Prothorax about three-fifths wider than long, the apex strongly 

 arcuate and continuous with the sides, the latter becoming gradually less 

 strongly arcuate and nearly parallel in basal third, the angles right, not 

 rounded ; base transverse, the sinuations rather broad but distinct ; disk 

 very feebly impressed along the middle toward base, rather coarsely, sparsely 

 punctate. Elytra three times as long as the prothorax, and, at the middle, 

 very slightly wider than the latter, gradually, acutely ogival at apex, the 

 sides parallel, feebly arcuate and continuous with those of the prothorax ; 

 disk with feebly impressed series of rather fine punctures, the intervals finely, 

 confusedly, sparsely and somewhat unevenly punctate, the punctures but 

 slightly smaller than those of the striae. Abdomen finely but strongly, moder- 

 ately sparsely punctured. Legs very slender, the basal joint of the hind tarsi 

 one-half longer than the remainder. Length 4.5 mm. ; width 1.6 mm.
