538 FAMILY XVII. ENDOMYCHIDJE. 



Throughout the State; frequent. January 8-November 14. 

 This and the next species hibernate, passing the winter months be- 

 neath logs, rails and chunks, especially those deeply covered with 

 (load leaves in fence corners or along the margins of upland woods. 



VI. LYCOPERDINA Lat, 1807. ((Jr., "a wolf + to break wind.") 



Here belongs a single oblong species having the front coxae con- 

 tiguous; thorax subquadrate, feebly narrowed behind, its base with 

 a deep transverse line and a short longitudinal one each, side, the 

 sides sinuate and margined ; elytra convex, the suture very finely 

 margined; scutellum broad and semicircular. 



*1027 (3181). LYCOPERDINA FERKUGINEA Lee., Ann. Lye. Nat. Hist, I, 1824, 



172. 



Oblong-oval. Piceous-black, shining; antennae, head, legs and narrow 

 margins of thorax and elytra brownish-red. Length 4.5-5.2 mm. 



Throughout the State; frequent. April 22-December 28. Oc- 

 curs most abundantly inside the little round fungus Lycoperdon 

 jti/rifornic Schaeff., which grows on old logs, where it feeds upon the 

 spores. By squeezing the ball, the beetle, if present, can be readily 

 felt. 



VII. APHORISTA Gorh. 1873. (Gr., "to mark off by boundaries.") 



Differs from Lycoperdrna mainly by having the front coxae nar- 

 rowly separated, the prosternum being distinctly prolonged between 



them. One species occurs in the State. 



*102S (31SG). APHOKISTA VITTATA Fab., Mant., I, 44. 



Oblong-elongate. Brownish-red, shining ; antennae 

 piceous, the terminal joint paler ; thorax with an in- 

 distiuet dusky spot each side of disk ; elytra with a 

 common sutural stripe, and each with a shorter one 

 on side, black. Length 5.5-6.2 mm. (Fig. 201.) 



A handsome and rather common species ; found 

 Fig. 201 x 5. (Original.) throughout the State. January 31-November 20. 



VIII. MYCETINA Muls. 1846. .(Gr., "fungus.") 



In this genus the prosternum extends behind the coxoa, but is 

 wider than in Aphorista and distinctly margined; thorax with deep 

 transverse impression near base from each end of which a length- 

 wise one extends forward to middle. One of the three North Ameri- 

 can species occurs in Indiana.
