LIST OF A SMALL COLLECTION OF ANTS PIERS 171 



This short list will serve as a slight contribution to our local 

 knowledge of these insects, and it is to be hoped that some other 

 student will take up and make reasonably complete the work 

 which Prest began. I do not happen to know of the publica- 

 tion of any other list of Ants of this province.* 



Nos. I to 29, and 36 and 37 were collected at Pleasantfield, 

 Queen's County; and Nos. 30 to 35 at North Brookfield in the 

 same county; and all in the same month, September, 1920, 

 except No, 37, which was obtained about July, 1919. 



The following five lots of specimens were not determined by 

 Prof. Wheeler, and therefore do not appear in the list: No. 10, 

 "nests under rocks in low lands"; Pleasantfield. No. 17, "nests 

 under stone; may be same as No. 18" (i. e. B. heeri subsp. 

 depilis); Pleasantfield; received in fragments by Prof. Wheeler. 

 No. 23, "nests beneath rocks; with Aphids on spruce root"; 

 Pleasantfield; also received in fragments. No. 26, "nests in 

 moss of meadows, a few inches above water; with Aphids"; 

 [possibly the same as No. 27, Myrmica brevinodis]; Pleasant- 

 field. No. 35, "duplicate or variety of a Pleasantfield species"; 

 North Brookfield. The above quoted notes are Mr. Prest's.

*H. S. Poole in 1900 published a very brief note on the periodical appearance of Ants 

 in a chimney at Stellarton, N S.. but he did not name or describe the species. See Proc. N. 

 S. Iiut. Sc., vol. 10, p. xlix.
