BICYRTES MESILLENSIS (Cockerell) 



Bembidula capnoptera Handliesch, var. mesillensis Cockekell, Davenport Acad. 



Nat. Sci., vol. 7, 1898, p. 142, male. 

 Bembidula mesillensis Cockebell, Can. Ent., 1899, p. 255, female. 

 Bicyrtes mesillensis Parker, Proc. U. S. Nat. Mus., vol. 52, 1917, p. 73. 



In the collection of the United States National Museum are to be 

 found two specimens of Bicyi'tes, a male and a female, bearing labels 

 that point to these two specimens as the ones on which Cockerell 

 based his description of this species. In my previous paper (cited 

 in the synonomy given above) I called attention to the divergent 

 relationships of the male and female that had been associated as 

 sexes of this species and raised the question of the validity of this 

 association. Since then I have examined a large number of Bicyrtes, 

 including both male and female specimens, in the collection of the 

 California Academy of Sciences, taken at the same time at Pepper 

 Sauce Canyon, Ariz., all of which I am convinced belong to a single 

 species. The females in this number I regard as belonging to the 

 same species as the female that Cockerell described as the female of 

 mesillensis, but the males of this number do not belong to the species 

 represented by the male on which viesillensis was based. It is my 

 opinion that this group taken at Pepper Sauce Canyon represents 

 either a regional variety of ventralls or possibly a new species and 

 that the female assigned by Cockerell to inesilleTisis belongs with 

 them, while the female of mesillensis still remains to be discovered. 



New Mexico: Las Cruces (Cockerell) male; Organ Mountains (Townseud)
