the other hibernated half-grown, and is at the time of writing commencing to 

 feed again. It is evident that at least a certain proportion of the larvse hiber- 

 nate twice; in the case before us this took place in a slight web uniting two or 

 three pine needles to form more or less of a protective covering; whether this is 

 the natural method or whether the larva descends to the ground ordinarily is 

 unknown to us. 



Plagiata larva is gray with a decided yellowish tinge; the dorsal tufts on 

 abdominal segmients 1-4 and 8 are deeper mouse gray, intermingled with plumed 

 white hairs; there are also lateral black hair pencils anteriorly and posteriorly 

 as well as a single dorsal pencil arising out of the tuft on the 8th abdominal 

 segment; the dorsal tubercles on the remaining segments show a rosette of short 

 plumed white hairs and a number of longer slightly barbed yellowish hairs; 

 the supra- and subspiracular rows of tubercles are very similar but contain in 

 addition a single (occasionally two) long black plumed hair. Subventrally 

 there is a fairly heavy clothing of long whitish, bipectinate hairs; the eversible 

 dorsal glands are coral red. 



Judging by the description given by Dr. Dyar of the larva of pini (1911 

 Proc. Ent. Soc. Wash., XIII, p. 19) the two must be very closely allied and 

 may even be identical; however, as we have had no opportunity for a careful 

 examination of either the larvae or the adults of Dr. Dyar's species the two 

 names may stand for the present as given in our Check List. 



KIRBY'S INSECTA: VOL. IV FAUNA BOREALI-AMERICANA. 

 RESTRICTION OF AN INDEFINITE LOCALITY. 



BY ALBERT F. WINN, WESTMOUNT, QUE. 



Anyone who has occasion to consult this volume about Canadian Insects 

 can hardly fail to notice the oft-recurring words "Taken in Canada by Dr. 

 Bigsby," and will probably lay the book down wishing that the author had 

 been more definite in quoting localities. While Canada in 1837 was of a very 

 limited area compared with our country at the present day, it was of large 

 extent. 



Some months ago, having an enquiry as to what part of Caneida, in my 

 opinion, the types of a species of butterfly described in this volume probably 

 came from, I tried to get a little light on the subject. The introduction to the 

 work conveys nothing further than acknowledgement and thanks to Dr. Bigsby, 

 of Newark, and Capt. Shepherd, of the Royal Artillery, for records for Canada, 

 and to Dr. McCuUoch and Capt. Hull for those of Nova Scotia. 



In the Redpath Library of McGill University, however, there are three 

 books by Dr. Bigsby. In one of these, entitled, "The Shoe and Canoe," by 

 John (Jeremiah) Bigsby, D.D., late Secretary to the Boundary Commission, 

 published in London 1831, I find the following: "Both my duty and my pleasure 



took me out of the common track — to Lakes Simcoe, Huron, Superior, 



etc., into a portion of Hudson's Bay and up the River Ottawa into Lake 

 Nipissing as well as to the rarely \isited Highlands of the St. Lawrence below 

 Quebec." 



It would seem safe to limit the locality "Canada" to the districts above 

 mentioned, and wide though they still are, all arc within the present boundaries 

 of the Provinces of Quebec and Ontario.
