I propose this name for the species identified as impiger 

 Walker by Dr. E. P. Felt, and fully treated under that name 

 in the monograph. A. impiger remains to be identified, which 

 may be possible from an examination of the types I select as 

 types of intrudens three males, Karner. New York, May 13, ■

This is the only species of the fauna whose adults enter 

 houses, which they do persistently. Both at White River and 

 Banff, with other species in abundance out of doors, only this 

 was encountered within, and often in such numbers as to be 

 distinctly annoying. 



The species ranges throughout the Canadian fauna and also 

 slightly beyond it. In the east it has been recorded from Mas- 

 sachusetts and it was abundant at Banff, Alberta, being the 

 commonest species early in the season after prodotes began to 

 diminish. It appears to be represented in the mountains of 

 California by A. Usheri Dyar, of which the male and larva are 

 unfortunately unknown. 



Males were beaten from bushes, but the swarming was not 

 observed. 



Eggs were obtained from captive females at Banff. The 

 single egg is rather stoutly fusiform, quite straight on one side, 

 the two ends pointed about alike ; black, shining, very minutely 

 and slightly granular ; micropylar area large. They are depos- 

 ited singly.
