192 THE CANADIAN ENTOMOLOGIST. 



obscurity he may have labored under through the careless report in Ent. 

 Am. will, I hope, be hereby dissipated. 



Proof of the carnivorous habit is what I was aiming at, and it is one 

 thing to presume a probable fact ; it is another thing to establish it. The 

 presumptive fact had been recorded here for four years, but the positive 

 fact was only obtained by Mr. Pergande at the time stated by me. 



Again, in another place (loc. cit. p. 152, paragraph 4) Mr. Edwards's 

 language would indicate, to one not familiar with my article, that I had 

 said something to the effect that no other butterfly had, or could have, a 

 carnivorous larva. He makes me say in fact that "this is the only but- 

 terfly known whose larva is carnivorous " ; whereas my language was, " so 

 far as I can find, there is not another recorded carnivorous butterfly 

 larva." No one could justly use his language who was not familiar with 

 the larva of every butterfly known ; whereas my remark simply emphasizes 

 mine as the first record of such a carnivorous butterfly larva and leaves 

 the impHcation that others may be found. 



I was much interested in the experience of Mr. Edwards and Miss 

 Morton, nOt only because it confirms the carnivorous habit of the species 

 announced in my paper, but because it adds so many interesting obser- 

 vations which tend to prove tlie carnivorous habit normal and not excep- 

 tional. 



Mr. Edwards has asked mc to publish the facts we have recorded here 

 in the C. E. 



Mr. Pergande's notes were merely chronological and colorational, con- 

 nected with the preserved egg-shells and about 30 larvse of all sizes. I 

 did not use them last spring because I had not time to go over the 

 material and draw up full descriptions that should combine structure as 

 well as coloration. Ill health has since prevented, and with Mr. Edwards's 

 very full descriptions there is no longer the necessity. In brief I may 

 state, however, that Mr. Pergande's notes show that : 



July 8, 1880, the larvae were found in the leaf curls of Pemphigus 

 (fraxinifolii) on Ash, and that the larvse died without feeding on the 

 leaves that wer6 placed with them. 



In 1 88 1 search was again made for the larvae on the same tree without 

 finding any. 



Aug. 23rd, 1882, three larvse were foimd on a twig of Witch Hazel;
