M. hamata. Say, det. Fox — Colora'o, near Rincon, July ii, at 

 flowers of Koeberlinia spinosa, Zucc. 



M. hyalina, Cress. — Common in the Mesilla Valley; on June 14, 

 I found the males flying in a swarm, in great numbers. 



Scolia flavocostalis, Cress., and S. lecontei, Cress., were taken by Dr. 

 S. Lewis in 1867. 



6". lecontei, Cress., S. dubia, Say, and 6". diibia, var. hcemaiodes, 

 Burm. , are recorded by Townsend from Vega S. Jose. 



6". ridifigsii, Cre^s., det. Ashm., was taken behind the Agricultural 

 College, Mesilla Valley, June 27, on mesquite. 



We have also two doubtful species of Scolia; one, from Lone 

 Mountain, is called by Mr. Fox S. cosfata, but I find no such name in 

 the catalogues; the other, from the Mesilla Valley, is stated by Mr. 

 Fox to be near vS". consors. 



Elis xantiana, Sauss., and E. zonaria, Cress., were taken by Dr. S. 

 Lewis. The former is not uncommon in the Mesilla Valley. 



E. plumipes, Drury, has been taken by Townsend in the Mesilla 

 Valley. I have also an Albuquerque specimen, received years ago 

 from Mr. Ashmead; it was probably collected by Prof. Wickham. I 

 took a specimen at Bernalillo early in July.
