H. Nelles in Bartlett Bay, off Glacier Ba>T-2L*«4?l!frand by Mr. 

 W. J. Wilson on the Hudson Bay Slope, were exhibited and 

 examined with much interest by those present. Dr. Fletcher 

 also exhibited the first number of the new Journal of Economic 

 Entomology, and a photograph of Prof. Aldrich, the author of 

 the Catalogue of North American Diptera. 



Mr. Halkett showed a series of larvae, pupae, and the male 

 and female beetles, of Dytiscus circiimcincliis , which he had taken 

 in the Qu'Appelle Valley and also in Cooking Lake, Alta. 

 This species is sometimes remarkably abundant at electric 

 lights in some of the western prairie cities. Mr. T. N. Willing, 

 at Regina. and Mr. J. D. Evans, in Winnipeg, saw early in 

 October enormous numbers of these beetles frying around the 

 street hghts. Mr. Halkett's larvEe and pupae were collected 

 in the beginning of August and the perfect insects were flying 

 in the beginning of October. Mr. Harrington exhibited his fine 

 collection of Dytiscidae containing many named types which 

 had been examined by Mr. John D. Sherman, of New- York. 



Mr. Nelles showed some beautiful photographs which had 

 been taken during his expedition of the past two years on the 

 Alaska Boundary Survey. These were examined with great 

 interest by all present. 



Mr. Baldwin shov/ed a handsome case of insects, the two 

 most interesting of which were a fine specimen of Eitbaphe 

 Iceta taken at Graham's Bush, Britannia, on July 7th, and a nice 

 specimen of Anarta cordigera taken on June 2nd. 



Mr. Gibson show^ed specimens of food stuff's infested b}- 

 the Grain Weevil. Calandra granaria, also pease infested by the 

 Pea Weevil, Bruchus pisorum, and beans by the Bean Weevil, 

 Bruchus obtectus. He drew attention to the different methods 

 of attack and gave a sketch of the life -history of the two species. 

 The seeds of Indian corn destroyed by Ptinus fur were shown 

 and it was stated that this was an unusual attack. Some galls 

 of the Prickly Raspberry gall made by Diastrophus nebulosus 

 were shown together with the gall m.aker. 



Mr. Young showed specimens of beetles of unusual occur- 

 rence at Ottawa wdiich he had taken during the past season. 

 Among these were DiccBhis ieter, Ditylus caeruleus, Phyxelis 

 rigidus and Lixus concavus. Of the last of these he had collected 

 three or four specimens upon a plant of Polygonum pennsylvani- 

 cum. Dr. Fletcher stated that this beetle was sometimes 

 injurious to rhubarb, the larvae boring in the stems and oc- 

 casionallv doing a considerable amount of harm. The Polygonum 

 belongs to the same natural order as the rhubarb. 



Mr. Harrington showed several of his beautifully arranged
