larvae, and pupae. On April 19th, fully 85 per cent of the overwintering larval 

 stage had pupated and were emerging as adults. In all probability there is 

 but one generation a year, the adult appearing in early spring and depositing 

 eggs in the young shoots in which the larvae develop until late fall and over- 

 winter as full grown larvae. 



"From present indications, it would appear that this joint- worm is a compara- 

 tively recent introduction into the Brooksville gardens, or else it has been there 

 for some time and is slowly developing into a serious pest. It is recalled that 

 in January, 1917, an inspector of the Florida Plant Board reported the finding of 

 a borer in bamboo from Avery Island. Unfortunately, this larva was not 

 preserved." The following observation was made by Dr. B. T. Galloway: 

 "The adult fly always pierces the node through the sheaf in such a position 

 that the egg may develop just above the node where the larval and pupal 

 stages take place."

NEW TIPULIDAE FROM BRITISH COLUMBIA (DIPTERA). 



BY C. B. D. GARRETT, Cranbrook, fi. C. 



The season of 1920 produced a large number of specimens 

 many of which were new to the Kootenay List, however, I did 

 not have the time this winter (1920-21) to work them further 

 than to the genera, the following few notes being of more than 

 passing interest were completed. On August 2, 1920, I was 

 lucky enough to secure a perfect female of that very rare fly 

 Profop/asa vipo O. S. I took it on the window of a pool room 

 in the center of Cranbrook, B. C., doubtless attracted there by 

 the light of the previous evening. This I think is the first 

 Canadian record of this genus.
