thduo-h there were plenty of good things at hand. My mind was set 

 on beani. r)n reaching the crest of the ridge that runs to the summit of 

 Mt. McLean, I was surprised to notice-two or three of the prize I sought, 

 but I soon found they were a long way from being in the bottle. I noted 

 the spot where I was sure I had seen one alight, but although I got quite 

 close I could not make it out. I found later on that the underside is 

 exactly the colour of the moss or lichen-covered rocks, and that when 

 they alight they turn over on their sides, but they are on the alert, and 

 one does well to get within ten feet. When they start they rise high in 

 the air and are off down the mountain side several hundred feet, .\fter 

 a while I struck a plan by studying its movements. I found if I kept a 

 little down one side of the ridge, they would often fly in m_\' directi'^n 

 or light near me. Even when one had the net over them, one would 

 have to be very careful as they would not rise into the net, liut lie flat 

 on the ground and sneak out under the net, but after many hours of 

 hard work up and down the ridge, I was well rewarded. As I got to the 

 summit I noticed that beani disappeared and that chryxus took their 

 place, and that they did not encroach on each others territory. 



This was in 1916. In 1917 there was not a beani to be seen on the 

 same ground at the same time of the year. The weather might have 

 li;id something to do with it, as I did not strike a good day the whole 

 of 1917. I saw a few beani near the head of Cayoosh Creek in 1917. 



Among my 1916 catch, I got two or three Brenthis astarte, but was 

 so intent on beani that I did not notice much about the habits of astarte. 

 In fact, I did not know I had made such a rare capture until later on. 

 I did not see an astarte anywhere in 1917. 



Erebia vidleri is fairly plentiful at from 4,000 to 6.000 feet, although 

 fresh specimens are not always easily got. 



Oeneis navadensis is found at one t)r two thousand feet. 



Eurymus nastes form streckeri is fnuiul here at abiju.t 7,000 feet. I 

 have never seen many, and they seem the hardest of any to capture, as 

 once they start they do not alight for a long time. 



I had the good fortune to get Heodes cupreus at al)Out 7,000 feet 

 in 1917. I also got a few at the head of a tril)utary of Cayoosh Creek. 

 The gold and red gives it a very striking appearance when in flight. 



One sight I witnessed on the jicak of Mt. McLean struck me as 

 peculiar. The air was literally full of flying ants and lad_\'-bugs 

 (Coccinellidae). I intend tr}ing to find out if the ants had their nest 

 there, (jr if they flew up from tlie vallev. 



Danaus archippus was quite common here in about 1915, but now 

 seems to have disappeared. 



The same thing seems to have happened to Pseudohazis hera. This 

 moth was quite common one season, and I got several specimens, but it
