so 



thick swampy meadow overgrown with willows, down to the river's edge, in hopes of 

 finding Chrysophanus Florus. We were, however, unsuccessful in this effort. Tip to 

 this time we had not seen a single Colias Interior, although a hundred miles east on our 

 journey up we had seen them in abundance along the line of railway. On this account we 

 decided to return the way we came, instead of going, as we had arranged, down the lake 

 foy steamer. Even if the species appeared before we left it could only be the males now, 

 •as they precede the females by about a week. "We had seen them abundant at Sudbury, 

 so decided to stop over there on the way back. There also lived Mr. J. D. Evans, an 

 enthusiastic collector, and one who was specially interested in C. Interior. 



In I. he afternoon we made an expedition up the wood road. Here we secured two 

 female Carterocephalus Mandan and numerous examples of Pliyciodes JS T ycteis, P. Tharos and 

 Lyccena Lucia. C. Mandan was one of our special desiderata. We had taken several 

 males, but these two females and another were the only ones we caught. They were at 

 once, in deference to Mr. Scudder's wish, caged over Poa pratensis. This species was of 

 particular interest to me, and after having bred the larva from the egg past the fourth 

 moult to hibernation, I still find it one of the most interesting butterflies I know. It is 

 rare but widely distributed. I caught my first specimen on Vancouver Island in 1885. 

 The same year Professor Macoun took it in the Rocky Mountains, and Mr. J. M. Macoun 

 took it at Lake Mistassini, and I have seen it in woods near Bobcaygeon, Ont. Erom 

 the positive statement in European works that the larva of the very similar C. Paniscus 

 feeds upon Plantago, I had tied specimens taken at Nepigon last year upon that plant, 

 but got no eggs. I should have made the same mistake this year but for Mr. Scudder's 

 knowledge. It illustrated well the value of experience. 



Before we caged our two specimens he maintained that he did not believe Plantago 

 was the food plant of our species, but said that if the egg proved to be ribbed, he would 

 alter his opinion ; if, however, it should be smooth and hemispherical, like those of the 

 Painphilida?, he was positive that grass was its food plant. As this was an important 

 question, we decided that if another specimen were taken we would dissect it, and discover 

 the nature of the eggs. Later in the afternoon this opportunity occurred, and the eggs 

 were then discovered to be smooth, as he had anticipated. The correctness of his views 

 as to the food, were also afterwards corroborated by the females laying on the grass and 

 the young larva? eating it readily, and refusing plantain leaves. The same day we caged 

 Amblyscirtes Vialis, Pamphila C ernes and Lyccena Lucia. The first two on grass, the last 

 on a, flower-bearing twig of Cornus stolomfera, the Red-osier Dogwood. As we passed 

 through the heavy herbaceous undergrowth, a sharp eye was kept on the stems of the 

 Epilobium august i folium for the larva? of the rare Alypia McCidlochii. In 1887 I dis- 

 covered this to be the food-plant without recognizing the larva?. Unfortunately no notes 

 were taken of their appearance ; all I can remember is that they were smooth and black, 

 with yellow markings — more like the larva? of Eudryas, I should say, than of Alypia 

 octomaculata. I collected two larva? and placed them in a jar with some of their food. 

 The next morning they had buried, and not thinking they were of any special interest I 

 did not unearth them. This spring I discovered, with chagrin, what they were, and 

 that I had no description of the larva. The pupa was very similar to that of Eudryas 

 grata, both in shape and colour. 



This day marked an era in the records of our trip. I find it underlined in my diary. 

 " To-day Chrysops first appeared in numbers." There seemed to be a plague of them. 

 Directly we entered the woods we were set upon, and at last were compelled to put nets 

 over our heads and wear handkerchiefs over the backs of our necks. Amongst the new 

 captures of the day were one specimen each of Lyccena Couperi and Argynnis Aphrodite, 

 the latter fresh from the chrysalis. 



On Tuesday morning, , 10th, Argnnis Bellona and A. Myrina were both tied over 

 plants of Viola renifolia, and eggs were laid within a few hours. Upon clover flowers in 

 a small meadow near the Hudson Bay Post, and, curiously, nowhere else, a few speci- 

 mens of Colias Philodice were taken. In the woods the Eurytheme and Keewaydin 

 forms of Colias Eurytheme were caught and tied on clover. After dinner we had decided 

 that we would take a tiip to "the Ridge." Soon after passing the railway bridge over 

 the Nepigon, our first specimen of Colias Interior was bagged. What a lovely species it
