line (greyish white) ; the middle area of the wing is bright 

 reddish liver brown (dark brown), and contains a central ovate 

 white spot (triangular) ; this bright colored area is separated 

 from the costa by a moderately wide longitudinal greyish stripe. 

 Secondaries, with a large white spot at the shoulder (small, 

 dirty wnite) ; the central area, bright reddish liver brown (dark 

 brown), having a central white spot, which varies from kidney 

 form to curved pear form, and varying much in size, but always 

 larger than the corresponding spot on the primaries ; but no 

 sexual difference could be observed, either in the size or in 

 the form, of these central white spots. 



The primaries beneath have the space from the shoulder to 

 the median white cross band of a maroon brown (black), and 

 generally the under side of the wings of Columbia nokomis is 

 brighter colored than that of Columbia. 



As I have not seen but one specimen of the Columbia winonah 

 type, little need be said about it. My specimen may have been 

 representative of an extreme northern group, or it may have 

 been only a strongly marked specimen of Columbia nokomis. 



THE BEE-EATING HABIT OF PHYMOTA EROSA. 



By Wm. Metcalfe. 



This fall at Grimsby, Ont., P. erosa was very abundant. I 

 first noted it July 24th, on which date a specimen of the larvae 

 was taken while in the act of feeding on the juices of tachina sp. 

 From August 1st till towards the end of September it was 

 exceedingly plentiful on various species of Solidago. Its 

 destructiveness to the honey bee, Apis mellifica must be a menace 

 to apiarists. I generally had a half day's collecting each week, 

 and on these occasions the number of dead bees hanging on the 

 flowers and lying on the ground was startling. Along a ditch 

 about one hundred and fifty yards in length, fringed with
