and polygonal, much shallower and g-radually evanescent toward 

 their posterior extremities, with the bottom polished, the hair borne 

 from a minute tuberculiform puncture adjoining- the anterior margin 

 of each. 



Five specimens, two of which were sent me by Dr. Blaisdell, of 

 San Diego. 



42 H. indlltus n. sp. — Oblong-elongate, parallel, rather strongly convex, 

 dull, piceous in color, the legs and antenuje slightly paler and more ferrugi- 

 nous ; pubescence short, extremely dense. Head feebly convex, the punctures 

 between the eyes moderately fine and distinctly separated ; eyes moderate, 

 separated by a little more than three-fourths of their width ; antennae rather 

 stout, not perceptibly attenuate, somewhat long, about two-fifths as long as 

 the body, the intermediate joints strongly obconical, about one-third longer 

 than wide, the third cylindrical and just visibly longer than the fourth. 

 Prothorax slightly more than one-third wider than long, the apex broadly 

 arcuate, nearly three-fourths as wide as the base, the latter transverse, the 

 sinuations narrow but distinct; sides broadly rounded anteriorly, becoming 

 nearly straight and parallel in basal half, the angles right, not at all rounded ; 

 disk convex, finely, deeply, very densely punctured, the punctures round and 

 slightly separated toward the middle. Elytra three times as long as the pro- 

 thorax and very slightly wider, rather obtusely ogival at apex, the humeri 

 slightly rounded to the base of the prothorax ; sides parallel and nearly 

 straight in basal two-thirds ; disk finely, extremely feebly striate, the striae 

 finely and inconspicuously punctured ; intervals very finely and excessively 

 densely punctate. Abdomen polished, minutely, rather sjjarsely punctured ; 

 prosternum and pro2)leur?e rather coarsely, extremely densely so. Legs 

 moderate, the basal joint of the hind tarsi slightly shorter than the re- 

 mainder. Length 5.0— 7.0 mm. ; width 1.9-2.5 mm. 



Texas (El Paso) ; New Mexico ; Arizona. 



The large amount of material before me is rather heterogeneous 

 and apparently involves two or three very closely allied species. 

 Some of the smallest forms are females, and two are labeled 

 "Florida," but this is probably an erroneous locality. 



The typical form is from El Paso, and has the punctuation of the 

 pronotum as described above and the pubescence rather dark in 

 color. Other specimens have the punctuation of this part slightly 

 coarser, densely crowded, polygonal and more rugulose, the pubes- 

 cence being a little longer, pale ochreous and much more conspicuous. 



All the specimens agree, however, in the extremely dense punctua- 

 tion of the elytra, which noticeably exceeds that of deplanatus, and 

 is even apparently denser than in macer. The species is allied to
