were kept was about equal. On the first day of July this year I took two 

 specimens of thoas in King's Co., N. B., and I have seen them on the 

 wing in St. John Co., a few miles from the city, at the same date in other 

 years. I have one example captured here a few days later.

Dear Sir, — 



I have got caterpillars of P. thoas or cresphontes taken in the garden 

 of A. Reid, in the west end of the city, feeding on a bush called the 

 " burning bush," from its going off with a blaze when light is held to it ; 

 I do not know its Botanical name. Two of them have gone into chry- 

 salis. J. Alston Moffat, Hamilton, Ont. 



[The plant referred to is Dictamnus fraxinella. — Ed. C. E.] 



Dear Sir, — 



On p. 195 of the present volume, the Can. Entom. makes me say that 



I regard Disippus as " probably the original type " of Basilar chid. I 



have never held such an opinion, but the very opposite.

Papilio cresphontes. — Mr. Wm. Murray, of Hamilton, writes as 

 follows : " We have a new butterfly in Hamilton and vicinity, and several 

 of them have been captured ; it is P. cresphontes (thoas). I got two of 

 the larvae this fall feeding on Dictamnus fraxinella rubra ; one has gone 

 into chrysalis, and the other died after it had hung up to undergo its 

 change." 



On the 1 6th of October, Mr. Watson, of Thedford, Ont., brought us 

 a specimen of this larva, which had been found feeding on Prickly Ash, 

 Xanthoxylum fraxineum. It was nearly full grown, and we fed it on 

 Prickly Ash and Orange leaves until it spun up. In the endeavor to shed 

 its larva skin it died when the chrysalis was more than half developed ; the 

 same fatality attended a specimen which we tried to rear last year.-Eo. C.E.
