Coleopterological Notices, III. 103 



Prothorax nearly three-fifths wider than long, the apex strongly arcuate and 

 continuous with the sides, the latter becoming parallel and distinctly arcuate 

 toward base, the basal angles right, not distinctly blunt ; base transverse, the 

 sinuations moderate ; disk very obsoletely impressed in the middle toward 

 base, finely, deeply punctate, the punctures separated by scarcely their own 

 widths, the interspaces rather strongly alutaceous. Elytra fully three times 

 as long as the prothorax and equal in width to the latter, rather abruptly 

 ogival in apical third ; disk with feebly impressed series of small but distinct, 

 not very approximate punctures, the intervals minutely and moderately closely 

 punctured. Abdomen minutely, very sparsely punctate. Legs moderate ; basal 

 joint of the hind tarsi almost two-fifths longer than the entire remainder. 

 Length 5.5 mm. ; width 2.2 mm. 



Texas. Mr. W. Jiilich. 



The general form of the body recalls rotundicollis, but the latter 

 differs in its larger size, much smaller eyes and broader terminal 

 joint of the palpi. In intermedins this joint is almost normal, recti- 

 triangular, with the very oblique apex scarcely longer than the 

 outer side. The head seems to be even unusually small. 



There is but little variation of any kind in the three specimens 

 before me. 



21 H. prolixiIS n. sp. — Elongate, subparallel, moderately convex, aluta- 

 ceous in lustre and rather dull, piceous to castaneous, the legs, abdomen and 

 antennae paler and more rufous ; pubescence short, rather sparse and incon- 

 spicuous. Head finely punctate, nearly evenly and rather densely so through- 

 out ; eyes large, separated by one-third their width in the male, one-half in 

 the female ; antennas long and slender, nearly one-half as long as the body, 

 the joints strongly obconical and much more than twice as long as wide, the 

 third and fourth equal. Prothorax one-half wider than long, the apex and 

 sides nearly as in occidentalis ; basal angles right and narrowly but very dis- 

 tinctly rounded ; base transverse, the sinuations broad and strong, the median 

 lobe broadly arcuate, projecting posteriorly as far as the basal angles ; disk 

 scarcely impressed, finely, deeply, densely punctate, usually slightly more 

 sparsely so toward base, the punctures anteriorly generally distinctly, some- 

 times rather widely separated. Elytra fully four times as long as the protho- 

 rax and very slightly wider than the latter, rather gradually, obtusely ogival 

 at apex ; sides parallel and nearly straight, the humeri somewhat abruptly 

 rounded to the prothorax ; disk with very feebly impressed series of fine but 

 deep, close-set, sublinear punctures, the intervals finely, confusedly and rather 

 sparsely punctate. Abdomen, under surface and legs nearly as in occidentalis. 

 Length 8.5-9.7 mm. ; width 2.9-3.2 mm.

This species is somewhat related to occidentalis, but differs in 

 several characters to a decisive degree. The punctuation of the
