THE DARKLING BEETLES. 1253 



2316 (7444). Blapstintjs intereuptus Say, Journ. Phil. Acad. Nat. Sci., 



Ill, 1824, 264 ; ibid. II, 155. 

 Oblong, rather robust and convex. Black, finely alutaceous ; elytra pic- 

 eous, obscurely tinged with bronze. Thorax three-fourths wider than long ; 

 sides straight to near apex, then converging to the apical angles; apex 

 broadly emarginate, hind angles acute ; surface rather densely and coarsely 

 punctured, the basal fo^-eaj well marked. Elytra together about one-half 

 longer than wide ; stri;a feebly impressed, very finely and closely punctured, 

 the rows more or less interrupted; intervals sparsely and rather coarsely 

 punctured. Length 4.5-5 mm. 



Throughout the state ; scarce. April 23-May 29. Several speci- 

 mens were taken from a dead hen and others from cement side- 

 walks and beneath rubbish, usually in sandy localities. Broader 

 and more oblong than the next. 



2317 (7445). Blapstini's metallicus Fabr., Syst. Eleut., I, 1801, 143. 

 Oblong-oval, convex. Bronzed, rather strongly shining. Thorax as in 



inteiTuptus, except that the disk is more finely and sparsely punctate at 

 middle. Elytral punctures coarse and widely interrupted in sets of one to 

 four or five, thus causing the surface to appear rugose; intervals flat, 

 sparsely and very finely punctate. Length 4~4.S mm. 



Lake, Marion and Vigo counties; frequent. IMarch 26-October 

 1. Occurs with moBstus and probably hibernates. Often attracted 

 by light. 



Tribe III. ULOMINI. 



Elongate or oval, usually somewhat depressed species having the 

 head immersed in thorax to eyes, which are transverse and emargi- 

 nate; front dilated to cover the base of mandibles; antennse 11- 

 jointed, the outer joints more or less thickened ; middle coxse with- 

 out trochantin, hind coxee slightly separated: tarsi pubescent be- 

 neath, the last joint much elongated. They live under bark, in 

 fungi or in dried vegetable products. Representatives of but five 

 of the 16 genera have been taken in the f^tate, though those of three 

 others perhaps occur. 



KEY TO INDIANA GENEEA OF ULOMINI. 



a. Antennae with the last two or three joints suddenly broader (except in 

 Tridoliuin confusum) ; length less than 5 mm. 

 6. Club of antennfB 3-.iointed ; einpleura very narrow at tip. 



X. Teibolidm. 

 6&. Club of antennre 2-jointed ; epipleura disthiet at tip. XI. Dicedus. 

 aa. Antennal joints gradually broader to tip. 



o. Base of thorax not margined, the hind angles never covering the hu- 

 meral angles of elytra. 

 d. Last joint of maxillary palpi oval ; length less than 4 mm.
