FAMILY XI. — STAPHYLINTDJE. 



isli-red. Antenna? reaching base of elytra. Thorax more than twice as 

 wide as head, three-fifths wider than long, sides rounded into base ; disk 

 rather closely and unevenly punctate on sides and with two elongate, shal- 

 low punctured impressions at middle, the space between them smooth. Ely- 

 tra slightly narrower and shorter than thorax ; densely and coarsely punc- 

 tate. Abdomen as wide as elytra, parallel, densely and coarsely punctate 

 above. Length 4-6.5 mm. 



Southern half of State; scarce. January 1— May 5. Occurs in 

 horse dung and fungi. Hibernates beneath logs. 



699 (2059). Aleochaka bipustulata Linn., Faun. Suec, 1761, 232. 



Rather slender, parallel. Black, strongly shining, sparsely pubescent; 

 elytra with an irregular dull reddish spot at inner angle near suture ; legs 

 piceous, tarsi paler. Thorax as wide as elytra, twice as wide as long, sides 

 rounded into base, punctate as in Mmaculata, the punctures on sides more 

 coarse and sparse than there. Elytra slightly longer than thorax, rather 

 coarsely, closely and deeply punctate. Abdomen as wide as elytra, parallel. 

 Length 2.5-4 mm. 



Beach of Lake Michigan. Lake County ; rare. June 6-June 28. 

 A member of the boreal fauna. A. niiida Grvh. is a synonym, as is 

 probably also A. verna Say. 



700 (9551). Aleochaea ltjcifuga Casey, Ann. N. Y. Acad. Sci., VII, 1893. 



288. 



Elongate, slender, parallel. Pale reddish-brown, shining; head and 

 dorsal segments of abdomen more or less piceous. Antennae stout, reaching 

 beyond base of thorax, the second and third joints subequal. Thorax about 

 one-fourth wider than long, sides evenly rounded, apex narrower than base ; 

 disk finely, sparsely and indistinctly punctate. Elytra very slightly wider 

 and about as long as thorax, rather coarsely, closely and roughly punctate. 

 Abdomen elongate, slightly narrower at base than elytra, thence feebly 

 tapering to apex ; the impressions of basal segments rather coarsely and 

 closely punctate. Length 4.5 mm. 



Two specimens were taken in Truett's cave. Monroe County, 

 July 9, about 700 feet from the entrance. They were found be- 

 neath some moldy chicken bones left by visitors. Casey, loc. cit., 

 says: ' 1 This interesting species is said to inhabit caves, but as the 

 eyes are well developed, it probably only seeks their seclusion and 

 darkness during the day." Carman* says of it and another spe- 

 cies: "Both have pretty well developed eyes, and may, therefore, 

 live at times in ordinary situations., but they are perfectly at home 

 m the deepest parts of eaves, and are at times very abundant there. 

 In all my collecting in ordinary situations I have not seen either 

 species out of doors, and am disposed to consider them true cave 

 dwellers." Mr. Carman is doubtless right, for no beetle is going to
