Coleopterological Notices, III. 121 



not polygonally crowded ; basal foveae almost obsolete. Elytra rather more 

 than three times as long as the prothorax, and, behind the middle, about one- 

 third wider, somewhat abruptly and obtusely rounded behind ; sides just visi- 

 bly arcuate; disk rather distinctly shining, not very finely, deeply, densely 

 punctate and with distinctly impressed series of slightly coarser, very approxi- 

 mate punctures. Abdomen very minutely, sparsely punctate, the prosternum 

 rather densely so but strongly shining. Length 4.8-5.0 mm. ; width 1.9 mm. 



Arizona. Mr. Morrison. 



This is a small species, somewhat allied to punctatissimus, but 

 easily distinguishable by its sparser punctuation especially of the 

 elytra, and the more distinctly punctate elytral striae, also by its 

 still more depressed form. 



The two specimens before me appear to be females, as there is no 

 trace of the peculiar sexual modification of the tibiae mentioned by 

 Mr. Champion. 



45 H. gemellus n. sp. — Oblong-elongate, somewhat strongly depressed, 

 parallel, dark brownish-piceous, the abdomen blackish, remainder of under 

 surface, legs and antennae paler, rufescent ; integuments somewhat shining, 

 the pubescence short, moderately dense. Head deeply punctured, the punc- 

 tures rather small and well separated between the eyes, finer and denser 

 anteriorly ; eyes moderately large, separated by about two-thirds their width ; 

 antennae moderately long and slightly stout, joints strongly obconical, nearly 

 one-half longer than wide, third just visibly longer than the fourth. Prothorax 

 rather more than one-half wider than long, the apex broadly, feebly arcuate, 

 three-fourths as wide as the base, not continuous in curvature with the sides, 

 the latter broadly arcuate anteriorly, parallel and nearly straight in basal 

 half, the angles right ; base transverse, the sinuations rather broad and dis- 

 tinct ; disk not impressed, finely, extremely densely punctate throughout, the 

 punctures round, not quite in contact, the very narrow interspaces shining. 

 Elytra quite distinctly more than three times as long as the prothorax and 

 just visibly wider, somewhat abruptly and obtusely ogival at apex, the humeri 

 very narrowly exposed ; sides parallel and nearly straight ; disk somewhat 

 finely and feebly striate, the striae finely but distinctly, closely punctate ; inter- 

 vals finely, confusedly and moderately densely punctate, polished. Abdomen 

 finely, very sparsely punctate. Legs normal, the basal joint of the hind tarsi 

 equal in length to the remainder. Length 6.0-6.3 mm. ; width 2.2-2.3 mm. 



Arizona. 



A somewhat inconspicuous species, more or less allied to several 

 others but especially deplanatus. From the latter it is readily 

 separable by its finer and rather sparser elytral punctuation and 

 much larger size. The three specimens before me were formerly a 

 part of the Levette cabinet.
