THE CANADIAN ENTOMOLOGIST 61 



was taken in flight in mid-day near the same locality on May 30; 

 in fact all females of this species which the writer has taken, have 

 been caught flying in daylight. This flash does not agree with that 

 of the insect which the writer supposed to be a male of P. angiilata 

 in 1912. 



5. Photinus consangitineiis Lee. This species was observed 

 at Plummer's Island, Md., on June 3, and along the Canal 

 on June 17. The interval between the two flashes constituting 

 the light-emission of the male, was found to be variable, some- 

 times as much as two seconds. Xo attraction of the male to the 

 electric bulb could be secured. 



6. Photinus scintillans Say. The previous obser\-ations on 

 this species were plentifully confirmed, but no new facts brought 

 forth. 



During this season a flash was observed on two separate oc- 

 casions, but in the same locality, which does not correspond with 

 that of any known Lampyrids of this vicinity. It consisted of a 

 series of quite rapid flashes, somewhat like that of the male of 

 Pyractomena lucifera, but of a distincth- orange tone. Both ob- 

 servations were made long after the normal period of prevalence of 

 the lucifera. It was found impossible to capture the insect at this 

 time, and the flash was not seen again, on later visits.
