B. C. ENTOMOLOGICAL PROCEEDINGS, 1912. 11 



Mr. Bush — Erebus odora has been taken all alonfi the Canadian 

 boundary line. 



Mr. Bi.ACKMdRE — I can concur with Mr. Anderson in the matter 

 of the apparent disappearance of Neophasia menapia. I never took one 

 during the past summer. 



Mr. Wilson — And I can remember a few years ago how the dead 

 bodies of this moth covered the waters of Esquimalt harbour they were 

 so numerous. 



Mr. Chairman — I will now ask Mr. Brittain to read Mr. Ven- 

 ables' report on the Okanagan District. 



REPORT FROM OKANAGAN DISTRICT'. 



During the past summer there has been a freedom from any 

 important insect pest in the V^ernon District. The summer was fairly 

 moist and heavy crops were for the most part the rule. 



H. ttxtor, the Fall Web Worm, was more abundant than for many 

 year>. It is always present to a greater or lesser extent upon its natural 

 food plant, the choke cherry, which is occasionally entirely defoliated 

 by the larvae. Burning out the webs with a torch is the most simple 

 method of extermination. 



The Cherry Slug was not very numerous during 1912 and the 

 second brood appeared very late in the season and larvae were found 

 feeding after several sharp frosts had occurred. The larvae of this Saw 

 Fly also feeds upon the wild thorn and are to be commonly seen upon 

 this tree during the summer. 



The Apple Aphis {A malt) appeared in some numbers during July 

 and spra\ing had to be done in the young orchards where the new 

 growth was in many cases covered with a mass of insects. The Black 

 Leaf 40 Mixture was used with great success in fighting this insect 

 as well as other species of plant lice. 



Some of their natural enemies were present in large numbers. A 

 species of Chrysopa the Lace Wing Fly, being numerous with their eggs, 

 each one of w-hich is laid at the extremity of a fine thread of silk about 

 half an inch in length often in clusters of twenty or thirty together, 

 resembling somewhat a cluster of delicate moss sporangiaphores. They 

 were remarked by several persons engaged in orchard work. 



The Coccinellidae were not so abundant as in other years when 

 Aphids were common, Hippodamla 5 signata being most numerous. 

 Besides this species Hippodamia convergent and Coccinella transverso- 

 gutta were noted as doing good work. I have in my collection 14 species 

 of this family of useful insects.
