Mr. Blackmore : The endin^gs, T think, are absolutely authentic. 

 At one time, as you know, the various species of genera ended in a 

 certain way. You could tell by the end of the word what class they 

 belonged to. 



Mr. Day : I shall now call on Mr. Anderson, of the Museum, 

 Victoria, to give his paper on " Insect Records from Atlin and Northern 

 British Columbia." 



INSECTS RECORDED IN THE ATLIN DISTRICT (NORTHERN 

 BRITISH COLUMBIA) DURING THE SUMMER OF 1914. 



By E. M. Anderson. 



(Reprinted from Proi'iucial Museum Report, 1914. by pennissioii of the 

 Director.) 



Since my report is of no economic value, I sincerely trust that it 

 will be of interest to some members present ; therefore, on a systematic 

 order, I shall endeavour to furnish you with extracts from my field-notes, 

 including a brief synopsis and annotated list of the insects collected in 

 northern British Columbia. 



In connection with the Provincial Museum of Victoria, I had the 

 honour of making an extended zoological expedition into the Atlin 

 District during the summer of 1914. Accompanied by an assistant, 

 Mr. C. B. Garrett, we sailed from Victoria on May 29th, via Skag'way, 

 Alaska ; thence by train and boat, arriving at Atlin on June 6th after a 

 most enjoyable and pleasant trip. On our arrival we found the town 

 of Atlin ("Atlin," a " Tahltan " Indian word meaning "Big Water") 

 nothing but a mass of ruins, save the Government buildings and a few 

 dwellings at the southern end of the town, these only being saved from 

 devastation after a fierce fire. The following day, after provisioning the 

 best we could under the circumstances, we departed from Atlin by wagon 

 to \A'ilson Creek, and after- a slow and rough ride we camped at the foot 

 of a steep mountain, close to a small lake, at an altitude of 3,000 feet. 

 On our arrival the weather was still cool, fresh snow lying on the foot- 

 hills close to camp ; the snow did not melt until about June 20th. This 

 spot favoured the collecting of insects, Diurnals, Geometers in particular. 

 Most of the material gathered at this camp is most desirable, and nearly 

 all proved good species. Six out of seven species of Brenthis taken on 

 this trip were found at Wilson Creek, including Brenthis improba Butler, 

 which is still very rare in collections. This beautiful form was found on 

 a grassy mountain-top, none being captured below 5,000 feet. 



The three listed forms of CEnis and both Erebias appeared on the 

 western slope of the mountains, while on the opposite side, only a short 

 distance of about two miles, we found a marked difference in the fauna. 

 Lycaena saepiolus, aquilo, and scudderi, commonly called " blues " ; Colias 

 scudderi and eryphile, the sulphur butterflies ; Pontia occidentalis var.
