^'Ab. I," it differing from others in having black before and between 

 stigmata, a common phase of variation in this group and allies. A cen- 

 tral shade is indicated in the tables, but not mentioned in description or 

 shown in figure. It is a still more common phase of variation in allied 

 species. It seems that there is really nothing tangible to separate cynica 

 from rubifera unless b}' the male genitalia. I should like to see a good 

 series of figures from males of both from the same locality.

COLLECTING NOTES FROM CARTWRIGHT, MANITOBA, 



We have had and suffered somewhat from a Yankee invasion in this 

 neighbourhood. A swarm of Cantharis mdtalli has come north out of 

 Dakota, and done some damage in gardens about Cartwright. A neigh- 

 bour of mine, an Englishman, has had all his broad beans eaten by them. 

 So the poor fellow will have no "beans and bacon" this year. He is an 

 advocate of reciprocity, so I tell him he has no cause to grumble. It is 

 only what he may expect, and things much worse, if that very one-sided 

 arrangement is carried into effect. 



This Ca?it/iaris, I may add, used to be rather abundant on the 

 unbroken prairie in my early days. It fed upon one of the vetches. I 

 forget its botanical name, but it is locally called the "buffalo bean." It 

 was a lovely sight to see two or three of them on the vetch flowers in the 

 bright sunshme, shining like emeralds shot with purple. 



In my early days Pieris protodice was the common " white " of the 

 prairies. I am speaking of the "eighties." As rapce reached here 

 J)rotodice gradually disappeared, and for years I have not seen a specimen. ' 

 On July 1 2th, when walking through a scrubby corner of my pasture, I 

 netted a "white" that came past me, killed it, thinking it was rapoe, and 

 was turning it out of my net when, to my surprise, I found it was a 

 protodice $ . Since then, about the same place, I have seen a second. 



A few nights on and after June 20th were favourable for collecting 

 at light, and I made some interesting captures on my windows and in my 

 trap, which will appear in Mr. Arthur Gibson's record. One curious 

 thing I noticed was that every night at 12 o'clock, as punctually as pos- 

 sible, Belostoma america?iu?n began to come to the light, and kept me 

 busy catching and killing them, as these great water-bugs, banging about 

 the window, drive away many desirable moths.
