FAMILY L. SCARAB JEID2*3. 



vertical carina divided at middle, thus forming two short tubercles. Tho- 

 rax minutely roughened, sparsely granulate-punctate. Elytra finely stri- 

 ate; intervals each with two rows of punctures, each puncture bearing a 

 short hair. Length 3.5-5 mm. 



Lake and Vigo counties; frequent locally. April 29— June 10. 

 Occurs beneath bones and skin of carrion and in fungi. 



1737 (5464). Onthophagus cribricollis Horn, Trans. Kans. Acad. Sci., 

 VII, 1881, 76. 



Rounded oval. Dark purplish, bronzed, feebly shining; sparsely pubes- 

 cent with short erect hairs. Head with two feeble transverse carina?, the 

 shorter one on the frontal suture, the other between the eyes. Clypeus 

 coarsely punctured, its front broadly and rather deeply emarginate, with a 

 triangular tooth each side of notch. Thorax broadest at middle, sides 

 oblique on basal half; surface coarsely, deeply and rather sparsely punc- 

 tate. Elytra finely striate ; intervals each with two irregular rows of rather 

 dense punctures. Front tibiae with four teeth, the second from apex the 

 longest. Length 3.5 mm. 



Lawrence County; rare. June 6. Taken from beneath horse 

 manure in wagon road, two miles east of Mitchell. Described from 

 Douglas County, Kansas and Texas, and not since recorded else- 

 where. Resembles a small form of janus, but the clypeus is dis- 

 tinctly two-toothed and the thorax is without sign of protuberance. 



173S (5463). Onthophagus pennsylvanicus Harold, loc. eit. 115. 



Form of tuber culifr ons. Black, feebly shining, sparsely pubescent. Cly- 

 peus entire or feebly truncate at middle, rather densely and coarsely punc-

 striate, intervals each with two rows of punctures. Length 3.5-5 mm. 



Throughout the State; common. March 6-September 28. Oc- 

 curs in carrion, dung and fungi. All the species of this genus bur- 

 row under the material in which they feed in the same way as 

 Cop r is. 



Tribe II. APHODIINI. 



Small, oblong, subcylindrical beetles, which live chiefly in dung. 

 They have the clypeus expanded so as to cover the mouth parts 

 (except in JEgialia) ■ middle coxa? oblique and contiguous, so that 

 the legs are close together; elytra entire, always striate and cover- 

 ing the abdomen ; ventral segments six,' all free ; tarsi with distinct 

 claws, with a small process bearing two setai between them. The 

 tribe is divided into nine genera, of wmich representatives of five
