 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 puucturt^d impressions at middle, the space between them smooth. I'jly-

 tate. Abdomen as wide as elytr;i, parallel, densely and coarsely punctate 

 above. Length 4r-6.5 mm. 



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

699 (2059). Aleochaba bipdstulata Ijinn., Faun. Suec, 1761, 232. 

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



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

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

Beach of Lake I\Iichigan, Lake County; rare. June 6-June 28. 

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

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

Two specimens were taken in Truett's cave, ^lonroe County, 

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

 neath some moldy chicken bones left liy visitoi-s. Casey, loc. cit. 

 says: "This interesting species is said to inhabit eaves, but as the 

 eyes are well developed, it probably only seel<s their seclusion and 

 darkness during the day." Garman=' .'^ays of it and another spe- 

 cies: "Both have i)retty well developed eyes, and may, therefore, 

 live at times in oniinary situations, but they are perfectly at home 

 in 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." ^Fr. Garman is doul)tlcss risiht, for no beetle is going to
