AMERICAN OOLEOPTERA. 97 



CICINDELID^. 



The general characters of the family have been so often treated 

 that I simply repeat the short diagnosis of Prof. Schaupp. 



"Antennae filiform, 11-jointed, inserted on the front above the base 

 " of the mandibles, which are long and sharply toothed ; hind coxse 

 " mobile and simple ; abdomen of female 6-articulate, of male usually 

 " 7-articulate." 



The genera, following Major Casey's revival of Dromochorus, are 

 separated thus : 



Posterior coxae separated, eyes small. 



Sides of elytra widely inflexed Amblyohila. 



Sides of elytra narrowly inflexed Oiniis. 



Posterior coxae contiguous, eyes large, prominent. 



Third joint of maxillary palpi longer than the fourth Tetrarha. 



Third joint of maxillary palpi shorter than the fourth. 



Legs and tarsi clothed throughout with fine decumbeut hair. 



Droiiiochoriis. 

 Legs often hairy but not clothed throughout CiciiKlela. 



Ai^IBLY€HIL,A Say. 



Contains one well-known species which occurs in Kansas and 

 other southwestern States, and two other imperfectly known species 

 which inhabit Arizona. These are :

A large brown or blackish insect, with paler brown elytra which are connate ; 

 head large, eyes small ; the scarcely margined thorax and underside smooth ; 

 elytra oval with three cariuae on each and irregular, unequal punctures; legs 

 long and robust, tarsi short ; wingless. 



% .—Hind trochanters acute with two grooves; small but dense yellow brushes 

 near the two tibial spurs of the middle legs ; last ventral segment broadly rounded 

 with large setigerous punctures each side of the middle; pygidium small. 



?.— Hind trochanters shorter, oval, obtuse at tip; last ventral segment some- 

 what prominent in middle and sinuate on each side with a feeble impression ; 

 pygidium very large. 



Length, 30 to 38 mm. = 1.20 — 1.52 inch. 



Habitat — Clay bluffs southwest of and near Wallace, Kansas 

 (most of the specimens now in collections were taken from this 

 place), and other places in Wallace Co., Kan. ; Gove Co., Kan. ; 

 Sun City, Barber Co., Kan. ; Colo. ; Ark. ; Indian Terr. ; New Mex. ;
