details should be re-interpreted in popular fashion for the 

 use of the average citizen. 



In the course of a week in the Park, during July, 1919, my 

 wife and I collected bees. The series obtained evidently rep- 

 resents only a minority of the species actually existing in the 

 area, but is worth recording. The names of the localities are 

 abbreviated as follows : 



(i) Canadian Zone. 



L. Long's Peak Inn. July 19 and 21. 



T. S. Twin Sisters Mountain, directly east of Long's Peak Inn. 

 All the collecting was done on the lower slopes, in the Canadian Zone, 

 July 23.* 



L. P. T. Long's Peak trail, July 18. Most of the collecting was 

 done in the Canadian Zone, but a few specimens probably were from 

 the Hudsonian. 



(2) Hudsonian Zone. 



H. Hudsonian Zone on Long's Peak trail, July 22. 



(3) Arctic-alpine Zone. 



T. L. Just above timber line on the Long's Peak trail, July 20. The 

 two species from Pentstemon flowers were at timber line. 

 B. Battle Mountain, well above timber line, July 20. 



COLLETIDAE. 



Colletes kincaidii Ckll. L., one $. 



Collates sp L., one <J . 



Colletes sp. L., one 9. This and the preceding are apparently 

 new, but they may have been described in Professor Swenk's re- 

 vision, not yet published. 



PROSOPIDIDAE. 



Prosopis personatella Ckll. L., 2 9 



Prosopis varifrons Cress. L., 2 $ . H, 1 3, 4?. L. P. T., 

 1 $. 



Prosopis tridentula Ckll. L. P. T., 1 $. 



Prosopis coloradensis Ckll. L., 2 9. These arc considerably 

 larger and more robust than /'. tucrtonis Ckll., generally considered 

 to be the female of coloradensis. Possibly tiicrtniiis is distinct after 

 all. but I cannot assert this at present. 



* l hi Twin Sisters, in an aspen strove, I took several specimens of 

 the Tipulid rly Ormosia cuckcrclli ( det. Alexander), a little yell<>\\ 

 species <1 -M-ribed by Coquillett under Rhypholophus in igoi, from a 

 single specimen which I took in the Hudsonian Zone in XYw Mexico. 

 Mr. Alexander had never seen any but the type.
