THE SHORT-WINGED SCAVENGER BEETLES. 



451 



slightly wider than elytra, sides very feebly curved; hind angles acute, 

 slightly prolonged; disk finely alutaceous, minutely and densely punctate. 

 Elytra together distinctly longer than wide, finely, densely and somewhat 

 roughly punctate. Abdomen minutely and closely punctulate on basal por- 

 tion. Length 3-4 mm. 



Lake, Starke, Marion and Lawrence counties; scarce. March 

 26-November 17. Taken by sifting. The depressed form, much 

 less curved sides and acute hind angles of thorax readily distin- 

 guish this from crassum, with which it has heretofore been con- 

 fused. 



867 (2651). Conosoma pubescens Payk., Monog. Carab. App., 1790, 138. 

 Oval, robust, convex. Dark chestnut brown, moderately shining, sparsely 



clothed with silken pubescence ; antennas and legs somewhat paler. Thorax 

 slightly wider than elytra, sides feebly curved, hind angles subacute, slightly 

 prolonged; disk very minutely punctulate. Elytra rather densely and 

 minutely punctulate. Length 4 mm. 



Lawrence County; scarce. July 29. Taken from decaying 

 fleshy fungi. 



868 ( ). Conosoma cakinula sp. nov. 



Broadly oval. Uniform piceous, highly polished, smooth and glabrous ; 

 antennae and legs reddish-brown. Thorax as wide as elytra, sides feebly 

 curved, hind angles rectangular. Elytra together wider than long, wholly 

 without punctures, each with three or four fine, straight ruga? or raised 

 lines on disk and a few oblique ones on sides. Length 2 mm. 



Vigo County; rare. October 6. Taken from beneath bark of 

 red oak. 



869 (2654). Conosoma oncuM Say, Trans. Amer. Phil. Soc, IV, 1834, 467; 



ibid. II, 583. 



Oval, convex. Piceous, shining, finely pubescent; elytra each with a 

 broad reddish basal cross-band: abdominal segments paler at apex; an- 

 tennae and legs reddish-brown. Thorax slightly wider than elytra, sides 

 regularly curved; hind angles rectangular; disk sparsely and finely punc- 

 tate, minutely strigose or alutaceous between the punctures. Elytra slightly 

 broader than long, rather densely and finely punctulate. Abdominal seg- 

 ments each with a seta from the sides of the upper surface and two at the 

 margin. Length 3-3.5 mm. 



Throughout the State ; frequent. May 6-November 17. Occurs 

 beneath the bark of fungus covered logs. 



870 (2653). Conosoma basale Erichs., Gen. Spec. Staph., 1840, 225. 

 Form and color of opicum. Thorax not strigose or alutaceous between 



the punctures. Reddish basal cross-band of elytra not reaching the side 

 margins, the humeri piceous. Length 3-3.5 mm. 



Throughout the State; frequent. April 15-October 31. Prob-
