OF PHILADELPHIA. 137 



2. A.^ STRIGATUS. — Black, clypeus convex on the disk; feet 

 dark piceous. 



Inhabits the United States. 

 /Scarab, strigatus Knoch in Melsh. Catal. 



Body deep black, immaculate : clypeus with very minute punc- 

 tures and larger ones at the base ; anteriorly emarginate ; middle 

 of the disk convex : thorax with rather large punctures, which 

 are remote on the disk and more numerous each side ; posterior 

 angles very obtusely rounded : elytra profoundly [213] striated, 

 striae punctured ; interstitial spaces convex : beneath black : feet 

 piceous towards their extremities. 

 Length nearly one-fifth of an inch. 



Rather a common species ; it is found in Pennsylvania and as 

 far west as the Rocky Mountains. It is longer in proportion to 

 its width than A. terminalis. 

 [A species of Euparia. — Lec] 



3. A. TERMINALIS. — Black, tip of the elytra and feet rufous; 

 clypeus trituberculate. 



Inhabits the United States. 

 Scarahseus stercoreus Melsh. Catal. 



Body black : clypeus with numerous distinct approximate 

 punctures ; three small tuberculi, placed in a transverse line, the 

 intermediate one rather largest ; anteriorly emarginate : thorax 

 punctured, punctures subequal and equally distributed ; posterior 

 angles subangulated, not obtusely rounded : scutel slightly ele- 

 vated into a longitudinal line on the posterior disk : elytra with 

 punctured strise; interstitial spaces perfectly flat; tip with a 

 large, common, obscure, rufous spot, sometimes obsolete, or di- 

 vided into two distant ones : beneath blackish : feet rufous black- 

 ish at base. 



Length more than three-twentieths of an inch. 

 The term stercoreus of Melsh. being preoccupied, I have ap- 

 plied to this species that of terminalis. It is readily distinguish- 

 able from our other species by the trituberculate clypeus, and the 

 uniformly distributed punctures of the thorax. 

 4. A. TENELLA. — Black ; elytra and feet rufous. 

 Inhabits the United States.
