 becoming paler in some examples ; legs pale testaceous throughout ; prothorax 

 small, much narrower than the elytra, the sides very discontinuous, only moder-

 sparse and scarcely visible throughout, really larger toward the middle but ex- 

 cessively feeble and shallow and variolate as usual ; elytra somewhat strongly nar- 

 rowed behind and evenly rounded from near the humeri, the apex rather nar-

 short but coarse, ashy and distinct. Length 1.5 mm.; width I. o mm. Arizona —
