234 THE CANADIAN ENTOMOLOGIST. 



Clara and Amyntula ; of Hesperians, Eudamus Nevada, Nisoniades 

 Propertius ; Pamphila Campestris ; Amblyscirtes ^.?//2(!j. Higher up the 

 mountain we met with nothing new. Although so Httle rain had fallen, 

 and the ground seemed dry as a desert, yet along the entire drive were 

 beautiful and showy flowers, great clumps of purple Penstemons, 

 white and yellow Oenotheras, and others, the names of which I 

 know not. 



On July 6th, Mr. Bruce brought in two great-bodied females Bairdii, 

 and these gave 117 and 76 eggs respectively. All the Papilios now were 

 fresh, and of the second brood of the year. Mr. Bruce also took a 

 Neonympha Henshawii, the first he had ever seen in this region ; also 

 Theclas Edwardsii and Titus, and Pholisora Catullus. 



On the loth, a fine and typical $ Hollandii was taken, matching 

 completely the female before spoken of; and no other such male was 

 taken during our stay. A $ Oregonia was bagged on the nth, and the 

 same day a Bairdii, confined two days before, Was found to have laid 70 

 eggs. 



I had now two lots of eggs of Oregonia and four of Bairdii. When 

 the females were bagged. Mr. Bruce and I were in all cases together, and 

 both examined the plants to see if perchance a stray egg might have 

 been previously laid on them by some other Papilio. And I may say 

 here that neither of us saw more than an occasional egg on any plant of 

 Artemisia in the six weeks. The plants are by thousands and the 

 butterflies few. All the bags were back of and close to the electric 

 power house of the Hotel, where were conveniences for shading them from 

 the fierce heat of the sun, and where there was no danger of trespassers — 

 two-legged or four-legged. When the bags were opened, I attended to 

 the eggs myself, clipped them off the stems, and put each sort in a box 

 by itself. Thenceforth all eggs and larvae were in my room at the Hotel, 

 and were attended to solely by myself. So there was nowhere a chance 

 of mixing up eggs or larvae, or of error. The bits of stem which carried 

 the eggs were placed in glass tumblers, labelled, and when the larvje 

 hatched, fresh stems were given, and these were changed daily. As the 

 larvfe grew, they were shifted to tin cans covered with cloth, and overlaid 

 by squares of heavy glass, to prevent escape as well as to afford light. 

 Treated in this way there was scarcely any loss. 



On 15th July Mr. Bruce left me for Denver and the high peaks 

 about Hall Valley, in order to get eggs of Chionobas CEno. From
