and middle pairs armed with a short tooth on the inner margin at 

 apex. Posterior tarsi as long as the tibiae, and the first joint equal 

 in length to the following joints united. Tarsal claws nearly similar 

 on all feet, cleft near the middle (the anterior pair slightly closer to 

 apex), the inner tooth broader and slightly shorter than outer one, 

 and not turned inward. 



Length, 7.75 mm. ; width, 1.75 mm. 



Female. — Differs from the male in being more robust and the 

 abdomen more broadly exposed above; front of head broader; pro- 

 sternum clothed with short recumbent, white hairs ; prosternal process 

 not concave; tibiae unarmed at apex, and the tarsal claws cleft closer 

 to the middle with the inner tooth distinctly shorter than the outer 

 one. 



Length, 8.25 mm. ; width, 2.125 mm. 



Type locality. — Arizona (male type) ; Baboquivaria Mountains, 

 Arizona (female). 



Type.— Cut. No. 41000, U.S.N.M. 



Allotype. — University of Kansas. 



Described from two examples, the male labeled simply "Ari." 

 without a definite locality, and the female collected in the Baboqui- 

 varia Mountains by F. H. Snow. In the female the pubescence on 

 the pronotum is slightly shorter than in the type, but otherwise the 

 differences are only sexual. 



This species is very closely allied to costipenms Fisher, but can be 

 readily separated from that species by the pronotum being not wider 

 than long, the pygidium distinctly carinate, and the posterior tarsi 

 as long as the tibiae, with the first joint as long as the following 

 joints united.

 in certain lights; beneath brown, with a distinct aeneous or aeneo- 

 cupreous tinge, especially anteriorly. 



Head with the front rather narrow, about equal in width at top and 

 bottom, the lateral margins parallel to each other, and with a deep, 

 broad depression extending from occiput to epistoma. the depression
