NEW RECORDS OF HEMIPTERA FROM BRITISH COLUMBIA 



p.v W. l)(iWNi:s. 



Since the year 11(21. when a rejiort on c<dlectiiuis of Hemiptera from 

 Britisli C'oluml)ia was published in this journal by Dr. II. M. Parsliley, 

 little has lieen recorded regarding- the Hemiptera of this province. Mueli 

 collecting has been done, liowever. and I have recently had an oppor- 

 tunity of working over the aecumtdated material. The jn-esent list adds 

 46 specie.s of Heteroptera and (i8 species of Homoptera, making 11.") atldi- 

 tional .species. This brings the number of species of Heteroptera known 

 to occur in the Province up to 2.1'2 and of Homoptera ls2. When we 

 consider the restricted areas in whicli collecting has been carried on, it 

 will be seen that these figures probably fall far shoi-t of the actual num- 

 ber of species occurring in our territory. ^lost of the collecting has been 

 done in the neighliourhood <if Victoria, and those records fi-om sucli 

 places as Penticton, Sumnierland and Vernon are usually the result of 

 short collecting trips of not more than one or two days duration, usually 

 in late summer or early fall. Veiw. little collecting has been done in the 

 neighbourhood of Vancouver and the Lower Fraser Valley generally, but 

 that district has yielded many species that find a favourable environment 

 in the humid coastal area. In 1920 and 1921 Mr. Buckell collected in the 

 Chilcotin and Barkerville districts and provided many new records and 

 some new species. 



I am greatly indebted to ^Mr. E. P. Van Duzee for his kindness in 

 giving me access to the collections at the California Academy of Sciences 

 and for much generous assistance in the determination of material, and 

 to the following gentlemen who have determined species in \ai-ious 

 groups: r>r. D. ]\I. De Long. Cicadellidae ; Dr. II. I'>. Ilungei-ford, Aquatic 

 Hemiptera; Dr. H. H. Knight. Miridae; and .Mi-. \V. L. .McAtee. Reduvii-
