274 THE CANADIAN ENTOMOLOGIST. 



Dr. Packard in his "Guide" says of the butterfly ; " It is found in 

 May, August, and Autumn," which would not indicate more than two 

 broods. 



Mr. W. H. Edwards, who bred this species repeatedly at Coalburgh, 

 says in the Can. Ent., X., 71, and XIV., 204, that in West Virginia 

 •' there are three broods and a more or less successful effort for a fourth." 

 " In Florida," he sa)'s, •' there are at least four broods, and probably 

 five," but that " in the Northern States, and probably in Canada, it is 

 two-brooded." 



Prof. Fernald in " Butterflies of Maine " says nothing of the num- 

 ber of broods, but mentions the dimorphic forms, so he must have recog- 

 nized that there were at least two broods. 



Mr. Scudder in his " Butterflies of New England" says it is double- 

 brooded, the first brood in descent from the hibernators appearing in 

 July, sometimes during the last days of June, and continuing into August, 

 the second brood beginning to emerge towards the end of August and 

 continuing to do so until at least the middle of October. 



In regard to the dates at which the hibernators appear in this latitude, 

 Mr. Winn records in his notes April 25, 1890 ; April 14, 1892 ; April 9, 

 1894; and found it quite common in New Brunswick the first week in 

 May in 1896, the specimens seen there being of the form Fabricii. A few 

 Fabricii were seen around Montreal during the latter half of May, but no 

 particular attention was paid to them ; but on the 6th June our Montreal 

 Branch joined the Natural History Society in its annual field day, but 

 separated from the party at Ste. Adele, at which point a number of 

 Interrogationis were seen, and two were taken by one of our members, but 

 both were of the form Umbrosa, though worn, and either hibernators or, 

 perhaps, colonists from the South. 



In this connection reference may be made to the experience of Mr, 

 W. F. Fiske, of Mast Yard, N. H., as written to Mr. Lyman, and since 

 then published in the Can. Ent., XXIX., 26. In this case no specimens 

 of Interrogationis were seen till the middle of May, when a badly worn 

 Umbrosa was observed, and during the rest of the month this form was 

 common, but no Fabricii were seen, and this certainly suggests the idea 

 that these individuals were colonists from the South. 



On 13th June our Branch had a little excursion to the Blue Bonnets 

 Swamp, about half way to Lachine, and several Umbrosa were seen and
