Pimplinffi. This was much admired by all present. He also 

 placed on view several cases containing his collection of local 

 species. These were of much interest. 



Mr. Groh exhibited a box containing about eight species of 

 plant lice illustrating the differences in size, wing venation and 

 general structure. Mr. Groh reported that he had given special 

 attention to the collection of plant lice during late summer and 

 autumn and had found these insects on about 70 different plants. 



Mr. Baldwin exhibited some lepidoptera, in all 20 specimens. 

 These were all of local species which had been collected during the 

 past summer. Some fine specimens were noticed of Oligia 

 festivoides, Melalopha apicalis and Azelina ancetaria. 



Mr. Young exhibited some living chrysalids of one of the 

 Orange-tips, (Anihocharis). These are curious objects with their 

 conspicuous keel-shaped projection. The specimens were collect- 

 ed by Mr. Young at Departure Bay, B.C. He also showed some 

 parasitized larvae, and living pupae of a species of Aids, a geo- 

 metrid moth. A general discussion followed on the pupation of 

 the Rhopalocera. 



Mr. Gibson showed a small collection of named Ephemeridae 

 which had been collected in Manitoba, chiefly at Winnipeg, by 

 Mr. J. B. Wallis. It was pointed out that good work could be 

 done in making collections of these insects and in observing their 

 habits, as little was known concerning the greater number of 

 Canadian species. A box of Hemiptera taken at Vernon, B.C., 

 by Mr. E. P. Venables was examined with interest. Among these 

 were specimens of Eurygaster carinatus, Carpocoris remotus, 

 Nysius scolopax and Geocoris uliginosus, var. limbatus. 



Rev. G. Eifrig exhibited a small collection of lepidoptera 

 which he had made in Germany in 1908. Also a few specimens 

 of the large handsome Mcrphns from Brazil. These were much 

 admired. A. G. 



January 7th, 1909. Held at the residence of Mr. Arthur 

 Gibson. Present: Messrs. Harrington, Simpson Baldwin, Eifrig 

 Jr., Groh, Halkett, Metcalfe, Young and Gibson. 



Mr. Harrington spoke at some length on the sub-familv Pim- 

 plinag of the Hymenoptera. He had been re-arranging his local 

 collection of these insects; and stated that 70 different species 

 are known to occur at Ottawa. Of these he exhibited 48 species 

 and gave information concerning many of them. The sub- 

 family Pimplinffi belongs to the super-family Ichneumoidea, the 

 members of which have unusually long and slender bodies. 

 They are decidedly beneficial in nature, preying upon injurious 

 kinds of insects; they thus render very important service to the 

 agriculturist.
