232 THE CANADIAN ENTOMOLOGIST. 



some one is in possession, and the land is irrigated by means of the 

 water that comes from every gulch and hollow, producing abundance of 

 root crops and all sorts of fruit — apples, plums, peaches ; (but no corn). 

 The morning after our arrival, Mr. Bruce showed me the river road 

 mentioned — a narrow, single track, invariably spoken of as " the trail," 

 now hot, dry, and covered with dust an inch or more thick. Where the hill 

 had originally sloped to the water's edge, the trail had been cut through 

 the rocks, and wherever there had been a little wider space, the base of 

 the hill to the road was covered with small pieces of rock that had fallen 

 from above. x-Vll along were clumps of Artemisia dracunculoides, and 

 here and there were thistles in bloom. About these last Papilios were 

 flying : a few Balrdii. Zolicaoii, Daiinus, Rutulus, Eurymedon ; not one of 

 which I had ever seen in life before. Also on same flowers, Pieris 

 Occidentalism and some Lycaenidae and Hesperids. Satyrus Paulus now 

 and then started up from the ground, or was seen flying slowly over the 

 broken rocks. We took half-a-dozen male Neominois Dionysius, 

 Scudder, a rare species described from Arizona or Utah, very little 

 known by anybody until Mr. Bruce found it at Glenwood Springs, in 

 1888. This butterfly has never been seen on a flower or at water, but 

 rises out of the dust at one's feet and alights at a little distance in dust 

 again, or else on the adjacent rocks, springing up like a grasshopper, 

 and, like that, turning its body around as soon as it strikes the dust or 

 the rocks before settling quietly. The temperature was high, and the 

 rocks were hot enough to roast eggs ; yet these creatures were manifestly 

 comfortable. The Papilios were none of them fresh — most of them 

 worn and broken, and evidently they were the last of the early brood. 

 The next day, July ist, Mr. Bruce went out alone in the opposite 

 direction from the Hotel, and returned about noon with 3 $ Dionysius, 

 4 $ Bairdii, i $ Sat. Paulus, and i ? Zolicaon ; all which we bagged 

 for eggs ; the Papilios on Artemisia, the Satyrids on grass. The Zolicaon 

 seemed to be in just the condition to give eggs, but refused. 



On the 3rd July was brought in a female Oregonia, and a typical ? 

 Hollandii. Also 2 9 Bairdii, and a $ Coena. Ochracea, all which were 

 tied up. The Hollandii beat herself in pieces and died without having 

 laid an egg ; and we never took another female of this form. In all we 

 got 38 eggs of Dionysius, 12 of Ochracea, and the Oregonia laid 81. 

 The Satyrid eggs were immediately mailed to Mrs. Peart, at Philadelphia, 

 who had kindly undertaken to help me in rearing any larvse. The
