276 AMERICAN COLEOPTERA. 



ArfeoUeres texanus n. sp. — Brown, sparsely pubescent with luteous 

 hairs, forming at basal third a larger patch, several smaller spots are transversely 

 placed at about apical third and one or two at sides ; the light hairs on the thorax 

 condensed in one spot on each side near apex, one on each near basal margin and 

 a short antescutellar line. Head coarsely punctured, sparsely clothed with lute- 

 ous hairs; antennje pale, except the ninth and tenth joints which aie darker. 

 Thorax coarsely punctate and feebly pubescent, sides slightly sinuate before the 

 hind angles, then arcuately narrowing to apex. Elytra convex, coarsely punc- 

 tate-striate, apex sinuate before the sutural angles. Body beneath sparsely pu- 

 bescent, metasternum more densely than the rest; presternum coarsely punc- 

 tate ; metasternum and abdomen, except last segment, very coarsely and sparsely 

 punctate with a few finer punctures intermixed, penultimate and last abdominal 

 segment much more finely and moderately densely punctate. Femora dark, 

 tibiie and tarsi pale. Length 2.25-2.5 mm. 



Brownsville, Texas, July. 



Brachy tarsus ornatiis n. sp. — Black, pubescence of upper surface dark 

 brown, cinereous and pale yellowish, the two latter colors forming on each ely- 

 tron an indistinct arcuate subbasal fascia and two broken up subapical fascise ; 

 legs indistinctly annulate. Head not convex, on the same plane as the beak; 

 the latter as long as the head, oblique at sides, apex truncate ; eyes slightly longer 

 than broad, emarginate behind; antennal cavities occupying the sides of the 

 beak and close to the eyes; antennae not quite reaching to base of thorax, first 

 and second joints stouter than the others, equal, third to eighth decreasing in 

 length, pale, club large, loosely jointed, black. Thorax at base as wide as long; 

 basal carina very feebly arcuate, rectangularly recurved and extending not very 

 far up the sides; the latter gradually narrowing to apex; surface indistinctly 

 punctate, feebly carinate at middle, the carina extending from base nearly to 

 middle; pubescence brown, with some paler hairs intermixed. Elytra elongate, 

 parallel, apex sinuate before the sutural angles; disk striate, strife feebly punc- 

 tate; pubescence dense, brown, variegated with cinereous and yellowish cinere- 

 ous hairs, the latter forming a subbasal, irregularly arcuate fascia, a subsutural 

 and submarginal line and two not clearly defined, transverse, subapical fasciae. 

 Body beneath sparsely clothed with cinereous hairs. Femora in great part dark 

 at middle, tibiae slightly annulated, tarsi pale, claws feebly cleft. Length 3 mm. 



Buckskin, Utah, June 15, 1904 ; collected by Mr. Jac. Doll. 



The annulated legs will separate this from our other species, ex- 

 cept alternans, from which it will be distinguished by the narrower 

 and more elongate form, the diffei'ent elytral markings and the longi- 

 tudinal carina of thorax, by which it also differs from all our other 

 species. The presence of a longitudinal, median basal carina on the 

 thorax is an unusual character in this genus, at least in our species, 

 but not sufficient alone to create a new genus. 



The markings on the elytra are a little obscure, not clearly defined.
