B. C. EXTOMOI.OGICAL SOCIETY 



His close companion and collaborator, Arthur H. Bush, was never happier 

 than when displaying the beauties of his wonderful collection to timid 

 tyros among the younger group of entomologists, and in giving them 

 assistance and advice. But to Capt. R. V. Harvey our society is particu- 

 larly indebted for the impetus which his splendid personality gave to the 

 initial growth of our organization. He had the rare faculty of inspiring 

 and fostering enthusiasm in all who were associated with him. Havini>- 

 travelled with him over three hundred miles of mountain trails, I learnea 

 to value him as an ideal "giiiile. jihilosopher, and friend." 



In conclusion, let me say that in our present society I believe we iiave 

 men of whom any similai- institution in America might well be proud. 

 The least that we can do is to foster that spirit of comeraderie and good- 

 fellowship without which the fires of achievement turn cold and crumble 

 into the ashes of disappointment. Give the word of praise and encourage- 

 ment now, when it may bear fi-uit, not reserving it as a flourish at the end 

 of an obituary. 



LEAF-ROLLERS ATTACKING ORCHARD TREES IN THE 

 OKANAGAN VALLEY

 Dominion Entomological Branch, Vernon, B. C. 



Tlie collection and breeding of larvae causing typical leafroller in.iu- 

 ry in the dry belt of British Columbia during the past few seasons has 

 revealed the presence of four species of tortricid moths, viz. : the fruit- 

 tree leaf-roller. Cacoecia argyrospila (^Valker). the oblique-banded leaf- 

 roller Cacoecia rosaceana (Ilaiiis). Tortrix alleniana (Fern.), and Pero- 

 nea maximana (B. and B.). Prior to the year 1918 injury caused by leaf- 

 roller larvae was as a rule attributed to Cacoecia rosaceana (Harr. ). It 

 was a matter of uncertainty as to whether the fruit-tree leaf-roller actu- 

 ally occurred in the Okanagan Valley at that time. This latter insect is 

 included in the check list of British Columbia Lepidoptera published in 

 1906, being recorded from the coastal district, and ;it Kaslo. It is also 

 listed by Dr. Dyar in his "Lepidoptera of the Kootenay District of Bri 

 tish Columbia" as having been captured near Field in 1903. It was first 

 actually bred from Okanagan material in 1922, though egg masses sup- 

 posedly referable to this species were noted by Mr. R. C. Treherne in 

 1921 on apple trees at Kelowna. Cacoecia rosaceana (Ilari-. ) has un- 

 doubtedly been present within tlu' i)rovince for a number of years, and 

 has been frequently mentioned in the lists of injurious insects of the 

 Okanagan Valley. Tortrix alleniana (Fern.) was first detected as an 

 orchard pest by the author in 1922, when larvae were bi'ed from apple 

 foliage at Vernon. The similarity of the life-history of this species to
