 Soc. Brit. Columbia, Victoria, System. Ser., no. 16, February 1920, 

 1921, pp. 7-15. [Received 12th January 1922.] 



This paper contains further information on species of Aeolothrips 

 [R.A.E., A, viii, 147]. The Hfe-history and habits of several species 

 are not well known. A. fasciatus has been recorded as common on 

 peas and beans ; in British Columbia it is frequently found with 

 swarms of Frankliniella tritici in flower heads, and it has been reported 

 in various parts of the world as predacious on other thrips. In Florida, 

 A . hicolor is often abundant on oats in the spring, and damages them 

 materially. In British Columbia, A. annectans has occurred with 

 Thrips tahaci on onion foliage. In Florida, A. floridensis is invariably 

 found in association with other species. 



A list of the species of thrips belonging to this family is appended. 



DowNEs (W.). The Life-history of Apateticus crocatus, Uhl. — Proc. 

 Entom. Soc. Brit. Columbia, Victoria, System. Ser., no. 16, 

 February 1920, 1921, pp. 21-27, 5 figs. [Received 12th January 

 1922.] 



A full description is here given of all stages of Apateticus crocatus, 

 Uhl., together with its hfe-history and feeding habits. This Penta- 

 tomid bug is fairly common in Victoria during the late summer and 

 autumn, and is of considerable economic value, as it feeds to a large 

 extent on tent caterpillars [Malacosoma] and those of Ellopia somniaria. 



Cockle (J. W.). Vitula serratilineella. Rag. A Honey-Feeding 

 Larva. — Proc. Entom. Soc. Brit. Columbia, Victoria, System. Ser., 

 no. 16, February 1920, 1921, pp. 32-33. [Received 12th January 

 1922.] 



Larvae of Vitula serratilineella, Rag., are recorded as infesting bee- 

 hives and feeding on the honey. A description is given of the mature 

 larva and of the pupa. This moth is nearly allied to V. edmandsi, 

 Pack., which has been stated to infest the nests of bumble bees. 



BucKELL (E. R.). Notes on the Ecological Distribution of some 

 Orthoptera from the Chilcotin District of British Columbia.— 



Proc. Entom. Soc. Brit. Columbia, Victoria, System. Ser., no. 18, 

 February 1921, pp. 32-38. [Received 12th January 1922.] 



This paper contains notes on the distribution of Orthoptera in 

 British Columbia in relation to the flora, etc., with a list of the species 

 collected during 1920. 



BucKELL (E. R.). The Locusts of British Columbia. — Proc. Entom. 

 Soc. Brit. Columbia, Victoria, Econ. Ser., nos. 13 and 15, June 

 1921, pp. 113-123. [Received 12th January 1922.] 



A brief outline is here given of locust outbreaks in Canada, and the 

 following are recorded as the species chiefly responsible for them : — 

 Cammda pellucida, Melanoplus atlantis, M. affinis, M. femur-rubnim, 

 M. hivittatus, M. packardi and M. spretus. 



The several methods employed in controlling them are reviewed, 

 and include the preparation and distribution of the Kansas and 

 Criddle baits [R.A.E.. A, i, 453; ii, 249; etc.], ploughing, and the 

 use of various machines for collecting the hoppers.
