80 THE CANADIAN ENTOMOLOGIST. 



laiva ; however, as I have elsewhere stated, I feel confident that careful 

 breeding will prove Lecontei, confusa and contigaa to be good species. In 

 his paper on Callimorpha (Can. Ent., vol. xix., p. 237), Mr. Smith is in 

 error in stating that I " assumed the distinctness of Lecontei and mili- 

 tarist I gave militaris as a variety of Lecontei and assumed the dis- 

 tinctness of Lecotitei and confusa, which is a very different thing, and 

 should have aided rather than misled him. I have found hibernated 

 specimens of Lecontei and confusa easy to rear, the latter in confinement 

 feeding freely on almost any kind of leaf. Might not these hibernating 

 Arctians be reared by placing them on ice, as Mr. Edwards has done so 



successfully with the diurnals ?

Dear Sir ■ In reference to Dr. Hagen's recent notice of Calverley's 

 illustrations of Sphingidae, I would say that the plates are neither " un- 

 known " nor "forgotten," but simply "unpublished." References to 

 their existence may be found in my printed papers. To certain of the 

 figures I furnished the types. Dr. Hagen makes some remarks as to the 

 quality of the illustrations. It is perhaps not remarkable that he does not 

 notice that many figures are copies from Cramer and Drury, and that the 

 plate of Papilio Calverleyi is the same as published in Proc. Ent. Soc. 

 Phil., on different paper. Copies of Calverley's Sphingidae were sent to 

 a few principal libraries, hence it is not extraordinary that Dr. Hagen 

 should have found one at Harvard. The work owes its inception perhaps 

 to the zeal of the late Mr. Stephen Calverley, who was a correspondent 

 of Doubleday. The names of its two original authors are remembered in 

 Limenitis Weidemeyerii and Papilio Calverleyi, as well as Deilephila 

 Calverleyi from Cuba. The text should have been written by myself, as 

 at one time at least intended, but the plates were finished at such irregular 

 periods and over so many years (i860 to about 1S69) that they were 

 never placed complete in my hands for the purpose.
