30 ENTOMOLOGICAL SOCIETY 



Ash mead, Sudworth, and Howard (active members), Dr. 

 Fletcher and Dr. Karlsioe (corresponding members), and Messrs. 

 Busck and Keffer (visitors), also present. 



Dr. James Fletcher, of Ottawa, exhibited a small but inter 

 esting collection of Diurnal Lepidoptera, made on the high peaks 

 of the Rocky Mountains, at Laggan, close to the summit of the 

 Continental Divide. The specimens shown were mostly taken 

 by Mr. T. E. Bean, a most indefatigable and careful collector. 

 Critical notes were given upon the occurrence and specific value 

 of some of the insects exhibited. Chionobas beani, Ercbia 

 disa, Argynnis astarte (rediscovered by Mr. Bean), A. alberta, 

 A. frigga var. saga, Colias christina, Lyccena aquilo, were 

 spoken of and compared with their nearest allies. He also 

 exhibited a collection of Diurnal Lepidoptera made chiefly by 

 Mr. C. De Blois Green, in the Okanagan Valley of British 

 Columbia. It was pointed out that this district falls within the 

 upper austral life zone, as laid down by Dr. Merriam. Interest 

 ing data were given on the dimorphism of Papilio oregonia and 

 P. bairdii. Mr. W. H. Edwards's experiments in breeding both 

 forms from eggs laid by a single female were spoken of at length. 

 Colias (Emilia, a very fine species, of which the original types 

 were lost some years ago, but which has been found again by 

 Mr. Green in the Okanagan Valley, was exhibited and compared 

 with Colias edwardsii, C. alexandra, and C. christina. The 

 speaker considered it a grand species and quite distinct from the 

 allied species mentioned. Z^yccena couperi w r as shown and the 

 speaker stated that he was unable to find sufficient differences 

 between L. couperi, L. afra, L. pembina, L. lygdamas (of Ca 

 nadian collections) , L. oro and L. antiacis var. bchrii, to separate 

 them as distinct. Many other rare species of butterflies taken in 

 British Columbia were spoken of and an outbreak of the white 

 pine butterfly {Neophasia mcnapia) was treated of at some 

 length. The larvaB, in the elevated arid plateau which forms the 

 interior of British Columbia, feed entirely on the leaves of the 

 yellow or bull pine {Pimis ponderosa*}, while on Vancouver 

 Island, where this pine does not occur, the larvaB live on the 

 foliage of the Douglas spruce and do much harm. In both 

 places, where the insect was observed in large numbers, the
