THE CANADIAN ENTOMOLOGIST. 



Male. — Tarsal joints 5-5-4; front and middle tarsi dilated; middle 

 and hind femora with a small denticle on the lower edge one-third from 

 the knee ; metasternum with a short tuft of hairs arising from a small 

 subbasal fovea. 



Indiana (Steuben Co.), May 25, 1909. 



Anisotovia opac'tpennis, n. sp.— Moderately stout and convex, rufo- 

 testaceous. Head and prothorax shining, finely punctate. Elytra finely 

 alutaceous and opaque, finely punctate striate, the ninth stria marginal, 

 except for a short distance at base ; alternate intervals with a single series 

 of distant punctures, the intervals otherwise impunctate. Head finely 

 alutaceous, but somewhat shining, rather closely punctate, a transverse 

 series of four or five larger punctures. Antenna; shorter than the pro- 

 thorax, third joint less than twice as long as wide and barely as long as 

 the next two,: joints 4-6 short, strongly transverse, 8 lenticular, y-io 

 large, subequal, 1 1 smaller, transverse, pointed. Prothorax strongly 

 rounded and widest at middle, sides strongly convergent, nearly straight 

 and a little sinuate in front, broadly arcuate and convergent behind ; hind 

 angles obtuse, ill-defined ; lateral margin sparsely fimbriate ; surface 

 sparsely, finely punctate, a little more closely at sides, and with a series 

 of larger punctures around the base angles. Elytra wider than the thorax, 

 sides nearly straight and parallel in basal half; epipleurae sparsely punc- 

 tate and with bristling hairs. Mesosternum oblitjue, carinate ; meta- 

 sternum and abdomen alutaceous, but moderately shining, distinctly 

 punctate. Front, tibiie flattened externally, subtriangular ; hind tibia; 

 rather strongly thickened apically ; hind femora very stout, suboval, less 

 than twice as long as wide ; front and middle tarsi long and slender, 

 nearly as long as the tibia;. Length, 4.2-4.4 mm. 



Described from two female specimens taken by the writer at El Paso, 

 Texas. 



The large size; form of prothorax, opaque elytra, fimbriate margins of 

 the body, very stout hind thighs and long tarsi mark this a very distinct 

 species, totally different from anything else in our fauna. Another feature 

 peculiar to this species exists in the very long spurs of the front tibiae, 

 these being very slender, parallel and about one-third as long as the tibia. 

 In all other species of the genus known to me the spurs are short, stouter, 

 and gradually pointed. 



Anisotoma similis, n. sp. — Very similar to coliaris, the description of 

 which in Horn's Monograph of the SilphidsP (Trans. Am. l^nt. .Soc, VIII,
