Priocnemis terminatus, Say, det. Fox — Albuquerque, June 30. 



Ceropales fiilvipes, Cress. — Collected by Townsend in the Mesilla 

 Valley. 



C. fratertia, subsp. occidenfalis, Ckll. — Ruidoso, about 6500 ft. 

 ( Townsend) . 



Pepsis formosa, Say — Common in the Mesilla Valley. The fe- 

 males agree ^ixX^Ci formosa, but the males are P. chrysothemts,'^K. Lucas. 

 Some specimens (c??) taken by Prof. Townsend at Las Cruces have 

 the wing-coloring of P. nephele, R. Luc, which should be known as 

 P. formosa var. nephele. The P. formosa of Lucas, distinct by the 

 characters of the cJ' abdomen (See Fox's table, Proc. Ent. Soc. Wash., 

 IV., 142), is apparently not known from the region whence came 

 Say's type, being more southern in its distribution. It may be called 

 P. pseudoformosa. 



Mixed Twith the males of P. formosa, I find I have a Mygnwiia 

 (presumably M. ustulata, Dahlb.) looking exactly like them. It was 

 taken at Las Cruces by Prof. Townsend.
