36 THE CANADIAN ENTOMOLOGIST. 



The most remarkable thing in the history of North Am. butterfly larvae is 

 the making these cases by all the species of Limenitis, and it would seem 

 incredible that the merest collector should not have known that. How 

 comes it then that no mention of such a habit should be found in a work 

 professing to have been written for instruction of beginners ? Nothing is 

 said under Ursula of such cases, but under Arthemis we are told that the 

 larvae " construct a case of leaves," instead of a case from a single leaf. 

 Moreover the larvae of these three species of Limenitis are described as 

 regards the processes on them as if they were radically different from each 

 other, whereas they are all built on the same pattern, and where one has 

 a process all have a similar one. 



Of Argynnis Myrina, we read that the larvae moult three times. Now 

 the larvae of the early brood moult four times, and of the late brood, five.

Under Mel. Phaeton, we read that these butterflies have restricted 

 areas, living in peaty meadows, and that the larvae make a web, but no 

 mention is made of the food-plant, Chelone glabra, which grows in such 

 meadows or in swamps, and is the reason for the presence of the butter- 

 flies there. 



Under Thecla I?-us, we read that Mr. Edwards says the eggs are laid 

 on wild plum, etc., " very interesting," etc. I said nothing of the kind. 

 My account was of T. Henrici, and I expressly said that I could not get 

 Irus to lay on plum. 



Under Lye. Pseudargiolus^ Mr. Edwards is quoted as saying that 

 hibernating larvae produce typical Pseudargiohis in spring. On the con- 

 trary, the larvae in no case hibernate, but the pupae do, some to produce 

 Violacea, some Psetidargiolus. 



Of Fenesica Tarqiiinius, we read that the larvae feed on wild currant, 

 whereas they feed on aphides only. 



Of Anthocharis Genutia : " There are two broods in the season, the 

 first of which appears in July." There is but one brood in the year, and 

 the chrysalis hibernates. The early butterflies, from these chrysalids, 

 appear at Newburgh, N. Y., early in May. Doubtless just as early in 

 Conn., which is given as their N. England habitat. 



Of Papilio Troilus : " The larvae spin a little roof over the leaf, draw- 

 ing the edges together." That might do for Pyrameis Atalanta, but not 

 for Troilus. The larva, as soon as out of egg, cuts into the border of the 

 leaf about one tenth inch and draws the part over, holding it down by a
