Pelecinidae 



Pelecinus Latreille 



P. polyturator Drury. The females are very common in 

 August, flying over lawns and ovipositing on the larva of 

 the June beetle (Phyllophaga). Taken as late as Oct. 3. 

 The males of this species are supposed to be very rare. 

 One was collected in 1921 and three in 1922 at N. E. Harbor 

 by A. R. Allen. On September 2 and again on the 7th, '33 

 we had a very strong south wind blowing downward. Sev- 

 eral were seen flying around the laboratory, and I took 

 seven. Dr. Brower, at the same dates, took them in Bar 

 Harbor. Can it be that the males fly at a higher level and 

 are not as rare as is supposed?
