699 (2059). Aleochara biplstulata 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 bimaculata, 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-Jiine 28. 

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

 probably also A. rmia Say.

288.

 dorsal segments of abdomen more or less piceous. Antenme 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;

Two specimens were taken in Truelt's cave, ]\Ionroe County, 

 •July 9, abottt 70(1 feet from the entrance. They were found be- 

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

 says: "This interesting sx^ecies is said to inlial)it caves, but as the 

 eyes are well developed, it ])robably only seeks thiMi' seclusion and 

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

 cies: "Both have ]iretly well d(H^(4oiied eyes, and may, therefore, 

 live at times in oi-dinary si1na1i(Mis. bul they ai'e [x'rfectly at home 

 in the deepest i)arts of i aves, and are at limes very abundant there, 

 in all my collcting in ordinary si1 nations T have not seen either 

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

 dwellers." Mv. Carman is donbfless riulit. for no beetle is going to
