Female. — Unknown. 



Holotype. — Male, in the Kansas University Museum.

 County, Ariz., July 27, 1927, by E. H. Beamer. 



The species resembles parksi^ from which it differs most obviously 

 in having no ocellars ; the hairs on pleura, cheeks, and paraf rontals 

 are entirely black; the paraf acials with two stout bristles on lower 

 part and a few scattered inconspicuous black hairs. The genitalia 

 show additional differences. 



(9) CUPHOCERA BUCCATA, new species

 haired. The intermediate fore tarsal segments are broadly dilated 

 in the female sex.
