THE SHOUT-WINGED SCAVENGER BEETLES. 



461 



890 (2696). Oxyporus lateralis Grav., Men. Col. Micr., 1806, 195. 

 Elongate-oblong, robust. Reddish-yellow; sides of elytra with a black 



or fuscous stripe, starting one-third behind humerus and gradually widen- 

 ing to apex; legs pale yellow. Head of male slightly narrower, of female 

 as wide as, thorax; surface, with that of latter, very finely alutaceous, 

 not punctate. Thorax slightly wider than long, sides broadly rounded. 

 Elytra one-half longer and distinctly wider than thorax, with a sutural 

 and one discal row of fine punctures with scattered coarser ones interven- 

 ing. Length 6.5-7.5 mm. 



Lake and Putimm counties; scarce. October 7-November 9. 



Taken on the latter dale beneath partly buried logs, and probably 



hibernates. 



891 (2692). Oxyporus occipitalis Fauv., Mars. Abeille, I, 1864, 369. 

 Form of lateralis. Color in part given in key. Elytra black, each with 



a triangular basal spot reddish-yellow; abdomen with a small black spot 

 on middle of second and third, and a much larger one on fourth and fifth, 

 dorsal segments. Thorax one-third wider than long, sides strongly curved. 

 Elytra with numerous very coarse punctures between the sutural and discal 

 striae. Length 6 mm. 



Lake, Marion and Vigo counties ; scarce. October 7-October 20. 

 The elytra are sometimes colored very nearly as in lateralis, but are 

 much more coarsely punctured than there. This may also prove to 

 be only a color variety of vittatus. 



Subfamily IX. OXYTELINAE. 



Small, usually slender species having the antennae 11- (rarely 

 10-) jointed, inserted under the sides of the front, the latter more or 

 less prolonged before the eyes; front coxae usually large, conical and 

 prominent; middle coxa- contiguous (separated in Oxytelus). The 

 subfamily as above defined is separated into six tribes, four of which 

 are represented in Indiana.
