NORTH AMERICAN COLEOPTERA. 78 



as attenuator. The latter is said to have the fVont an(j;les of the lliorax 

 reddish (Col. Hefte xii, p. 22), but the type kindly given me is quite 

 black all over, and it is probable that the specimen described may 

 have been immature. Notwithstanding the wide distribution of this 

 species it seems to vary but little. 



Occurs from Massachusetts (Blanchard) to every point west and 

 south, California and Arizona, thence through Mexico to South 

 America. It has not yet occurred in our northwestern regions. 



A. L<ecoiitei Harold. — Form of cyliiulrus, piceous or l)lack (reddish hrown 

 when immature), moderately shining, legs reddish brown. Antenuse nifotesta- 

 ceous. Head moderately convex with coarser punctures along the occiput, the 

 front and clypeus finely obsoletely punctured. Clypeus impressed in front, 

 broadly, but feebly emarginate, slightly angulate each side, the sides arcuate, the 

 genie feebly prominent, obtuse. Thorax similar in form to cylittdrns, the ])unc- 

 tures rather coarse, not densely placed, except at sides; in front with few punc- 

 tures. Elytra oblong oval, humeri dentiform, as wide at base as the thorax, 

 striye deep and rather broad, the punctures coarse, not sen-ate, intervals convex, 

 subcarinate at apex and with a row of indistinct punctures on the inner side 

 below their apices. Mesosternum opaque rugulose, cariuate between the coxae, 

 Metasternum indistinctly punctate at sides. Abdomen coarsely sparsely punc- 

 tate, segments 2-5 creuate in front. Legs as in cylindrus. Length .14-.16 inch ; 

 3.5-4 mm. 



This species is clo.sely allied to cylindrus, but ha.*! the elytral inter- 

 vals much less cariuate on the disc, the thorax is more coarsely and 

 less den.sely punctured and the punctures are very much .-^parser 

 behind the anterior margin. 



Occurs from the District of Columbia to Louisiana. 



A. iiiops n. sp. — Moderately elongate, i)arallcl, feebly convex, reddish brown, 

 shining. Head moderately convex, the occiput indistinctly punctate, entire front 

 granulate. Clypeus broadly feebly emarginate ; a small, acute tooth each side ; 

 sides arcuate, gense feebly prominent, obtuse. Thorax about one and a half times 

 as wide as long, not narrowed in front, sides very regularly, but feebly arcuate, 

 hind angles broadly rounded, base arcuate the marginal line fine, di.sc moderately 

 convex, the punctures not coarse, but very regularly and moderatelj' closely 

 placed, a little finer near the front, and with a smoother space near the hind 

 angles. Elytra as wide as the thorax, humeri finely dentate, sides parallel, disc 

 striate, striai punctured, intervals feebly convex, crenate on their inner edge and 

 with a row of very fine punctures on the outer side. Jlesostemum opaque, finely 

 strigoso-punctate, cariuate between the coxa>. Metasternum finely punctate 

 at middle, slightly rugose at sides. Abdomen rather coarsely punctate, the junc- 

 tures finer and sparser at middle, denser at sides. Anterior tibiaj tridentate ex- 

 ternall}', not crenate above. Posterior femora almost entirely smooth, a short 

 trace of a nuirginal line near the knee ; posterior tibise without accessory spinule, 

 the first tarsjil joint shorter than the long spur. Lengtii .14-.1(J inch ; 3.5-4 mm.
