KEY TO INDIANA GENEKA. OF ENDOMYCHIN.ZE. 



a. Ligula oblong, rounded at tip; thorax black, elytra red, each with two 

 black spots. V. Endomychus. 



aa. Ligula transverse, emarginate or truncate; color not as above. 



b. Prosternum not prolonged behind; front coxes contiguous or nearly 

 so ; thorax and elytra nearly uniform piceous black above. 



VI. Lycoperdina. 



bb. Prosternum prolonged behind, partly covering the mesosternum ; front 

 coxae separated. 



c. Prosternum narrow between the coxae ; elytra in our species with 

 lengthwise stripes. VII. Aphoeista. 



cg. Prosternum wide, margined; elytra without stripes, either uni- 

 colorous or with spots. 

 d. Thorax without an impressed submarginal line ; body glabrous. 



VIII. Mycetina. 

 dd. Thorax with an impressed submarginal line ; body pubescent. 



IX. Stenotaesus. 



V. Endomychus Panz. 1795, (Gr.. "within + nook or corner. ") 



Antennae elongate, with a loose, not large club ; sides of thorax 

 feebly sinuate, strongly but narrowly margined; longitudinal basal 

 impressions deep, the usual transverse line represented only by a 

 very fine basal margin ; prosternum flat, spoon-
