SYNOPSIS OF THE SPECIES 



1. Thorax with distinct basal marginal line conferta 



Thorax without basal marginal line sjiissipes 



Aegialia conferta Horn. 



1871. Aegialia conferta Horn, Trans. Amer. Ent. Soc, iii, pp. 



293, 294. 

 1910. Aegialia conferta Blatchley, Coieoptera of Indiana, p. 921. 



Specimens examined : 5, collected at West Point in June, 

 1888. This is probably the commonest and most widely dis- 

 tributed species of the genus, and doubtless occurs more fre- 

 quently in the state than the material at hand would seem 

 to indicate. 



Aegialia spissipes Le Conte. 



1878. Aegialia spissipes Le Conte, Proc Amer. Philos. Soc, p. 611. 



Specimens examined : 6, collected at West Point in June, 

 1888. Spissipes is less common than the preceding species. 

 It is recorded from Michigan and Massachusetts. 



Aphodius Illiger 



Aphodius is one of the largest genera in the family Scara- 

 baeidae, and is represented in the North American fauna by 

 103 species. Many of these are widely distributed and sev- 

 eral of them nearly cosmopolitan, which is a rather unusual 

 circumstance among the higher groups of insects.
