THE SHORT-WINGED SCAVENGER BEETLES. 



457 



884 (2670). Bbyoporus rtjfescens Lee, N. Sp. N. Amer. Col., I, 1863, 33. 

 Elongate, rather robust. Head, under surface and abdomen piceous; 



antennae, thorax, elytra and legs dark reddish-brown, shining. Thorax wider 

 at middle than elytra, hind angles broadly rounded. Elytra together longer 

 than wide, with seven rows of coarse, shallowly impressed punctures. Ab- 

 domen sparsely pubescent, sparsely and rather coarsely punctured, the last 

 two segments and the hind margins of the others paler. Length 3.5-4.5 mm. 



Throughout the State, frequent ; more so in the southern coun- 

 ties. March 20-June 17. Occurs beneath bark and rubbish. Much 

 more robust than the next species, with the elytra! punctures much 

 coarser and in regular rows. 



885 ( ). Bbyopobus testaceus Lee, N. Spec. N. Amer. Col., I., 1863, 33. 



Elongate, very slender. Head and thorax piceous; elytra reddish- 

 brown, often with an indefinite sutural blotch darker; under surface and 

 abdomen dark reddish-brown, the segments of latter paler at apex; an- 

 tennae dusky, paler at base; legs pale reddish-brown. Thorax as wide at 

 base as elytra, smooth, strongly shining. Elytra distinctly longer than 

 wide, the punctures of sutural row distinct, the others small, faint and m 

 somewhat irregular rows. Abdomen pubescent, rather finely and sparsely 

 punctate. Length 2.7-3 mm. 



Marion, Putnam and Posey counties; scarce. March 20-Octo- 

 ber 14. Taken by sifting. Resembles Mycetoporus americanus but 

 without the discal punctures of thorax. This species was suppressed 

 by Horn, and afterward redescribed as parvulus by Casey. 



Tribe V. HABROCERINI. 



This tribe is represented in the United States by a single genus, 

 Habrocerus, having the hind coxae broadly triangular, concealing a 

 part of the femora in repose; head denexed, antennas slender, hair- 

 like; abdomen margined. One small piceous form, H. schwarzi 

 Horn, 2 mm. in length, having the elytra pale clay yellow, finely and 

 very sparsely punctate, was described from Detroit and probably 

 occurs in northern Indiana. 



Subfamily VI. PHLOEOCH A RIN AE. 



Slender, depressed species having the antennae inserted under 

 the sides of the front, 11- jointed, straight, the outer joints but little 

 thicker; head without ocelli; presternum behind the front coxae 

 membranous ; abdomen elongate, margined, with but six ventral seg- 

 ments visible, the second with a longitudinal elevation at middle ; 

 tarsi 5-jointed. The subfamily is represented in Canada, Michigan 

 and perhaps northern Indiana by two genera.
