THE CANADIAN ENTOMOLOGIST. 407 



end lo buiieifly activities, we patrolled the roads, explored the underbrush 

 or watched the imprisoned females, in an endeavour to gain some hint of 

 the secret we had come to discover. Before evening we had managed to 

 add four living females to our catch, but had observed nothing which 

 narrowed the circle of probable food-plants, and thus the time to leave 

 Lakewood found us no wiser than before. 



On a purely theoretical basis it seemed likely that the food-plant 

 would prove to be one of the EricacecB (the dominant family in that region 

 of sand and bog), and, if so, probably some ericaceous species not found 

 at Albany, since the butterfly does not occur here. Accepting this 

 tenuous hypothesis for lack of a better guide, I brought home cranberry, 

 sand-myrtle, laurel (Kalmia latifolia) and Androjiieda sp. Mr. Watson 

 took one female to New York, and kept her shut up with Pyxidanthera 

 barbnlata until she died, but secured no egg. Five of the other six 

 reached Albany alive, and were put in a large "cage" with the plants 

 brought from New Jersey, and a number of possibilities from the local 

 flora. 



The record for the next itw days is mournful reading ; it all belongs 

 to the obituary column. The last of my females died on the 15th without 

 having yielded ova, and I immediately wrote to Mr. Watson to meet me 

 in Lakewood on the Saturday following. Meanwhile I dissected one of 

 the butterflies, and was greatly pleased to discover that the eggs were very 

 different from those of the congeneric species, and could be identified 

 without difficulty. 



I reached the Lakewood locality early in the afternoon of the 17th. 

 The day was cold and cloudy, and not a butterfly was seen. I examined 

 as much of the pyxie and sand-myrtle as was possible before nightfall, but 

 my only reward was an aching back. 



Saturday dawned clear, warm and delightful, and before 8.30 I was 

 in the field awaiting the butterflies. Brizo, iroilus, philodice, cotnyntas, 

 juvenalis and ladon added to the pleasure of a typical May morning \ 

 augustus was abundant, and several ?iiphon and one irus were taken, but 

 polios had apparently disappeared for the season. I did capture one, but 

 as it proved to be a male I released it. The prospect was discouraging, 

 and there was nothing to be done but to continue the uncomfortable search 

 for eggs. This I did religiously but without much heart all the afternoon.
