UHLER ON INSECTS. 767 



Safyrus sp. 



A pair from Mauiton, August 14. They were captured in the midst 

 of the bushes on the side of the hill adjoining the road leading up the 

 Ute Pass. No others were noticed. It is interesting to observe that 

 here are two parallel species, each frequenting a canon of the Eocky 

 Mountain belt, but occupying separate territory, and perhaps represent- 

 ative of two distinct fauna! districts. 



Thecla sp. 



A specimen of this exquisitely beautiful butterfly occurred to me on 

 the bank of the creek, near Manitou, on August 13. 



Chrysophamis helloides Boisd. 



A few specimens occurred on the plains, near Denver, on August 5. 

 It is very wary, hiding among the dense foliage of the flowers, and 

 selects its resting places with such tact that it promptly becomes invisi- 

 ble to the collector who is following it. 



Lyc(cna melissa Edw. 



Found sparingly in Clear Creek CaQon, August G ; near Denver, Au- 

 gust 5, and later ; at Colorado Springs and Manitou, August 12 to 16, 

 quite common on low plants and very variable ; and one specimen from 

 CaSon City, August 11. The latter specimen has an arcuated orange 

 band on both front and hind wings, while one from Colorado Springs 

 has a similar band on the hind wings alone. 



Lycccna rapahoe Eeakirt. 



This modest bluet was seen in. small numbers at Denver, August 5, 

 but not much later, and near Colorado Springs on August 12 to 16. 



Pholisora catullus (Fab.) Scud. 



Taken in Clear Creek Canon and west of Denver, August G and 18. 

 Not common in either locality. 



Hesperia tessellata Scudder. 



On the low hills west of Denver and near Sloan's Lake on bare patches 

 of ground in grass, August 18. A few specimens were met with at 

 almost every interval of two or three rods. 



Hesperia comus Ed%yards, MS. 



In company with the preceding, and equally frequent. On being 

 aroused, these species did not fly to the patches of flowering plants and 

 weeds near by, but invariably alighted on the spaces between the buf- 

 falo-grass, where their colors sutSciently harmonized with the soil to 

 give them a fair degree of protection. 



Anthomcifiter iincas (Edw.) Scud. 



Somewhat common on the hills west of Denver on August 18. 



Pamphila manitoba Scud. 



Uncommon in Clear Creek Cafion, August 6.
