Oblong-ovate, niodorately robust. Dark i-oddish- or chestnut-brown to 

 piceous, the surface usually with a pnriilisli or hoary <-oating. Clypeus 

 broadly emarsinatc, densely punctured, the front more coarsely and roughly 

 punctured. Tliorax with margin serrat(\ sparsely ciliate; disk with very 

 coarse, closely placed punctures, dense near the front angles, the median 

 line usually smooth. Elytral punctures fine, indistinct, sparsely placed ; all 

 the costfe moderately distinct. Metasteriuun densely punctured, the hair 

 long and dense, male; sparser and much shorter, female. Male with an- 

 tennal club a litllc long(>r than the funicle; abdomen flattened at middle, 

 fifth segment with a strongly elevated, rugose ridge behind which the seg-

GRorp C. 



To this group belong a number of our best known and most com- 

 mon species. All agree in having the body not pubescent above, 

 usually shining, rarely pruinose or iridescent; antennae lO-jointed; 

 clypeus usually emarginate; hind tibia3 truncate at apex, without 

 trace of sinuation at the base of the fixed spur, this spur usually 

 long and straight. Twelve species have been taken in the State, 

 while four others perhaps occur.
