same way. The species of hickory upon which they were found was 

 what is known as the Mockernut, or Carya Tomentosa. 

 • The eggs hatched, or about one-fifth of them, April 17th, 1887, the 

 rest coming out from day to day after this, and they emerged from the 

 pupae from June r4th to 16th, giving an egg period as above of at least 

 194 days, to which it is probable that at least two weeks more should be 

 added ; and from the time of hatching to the emergence of the imagines 

 58 days, of which one month is in the pupa state. I have no reason to 

 think that this, or any other species we have here, is more than one 

 brooded. I am also of the opinion that they pass through changes 

 sooner in the hatching boxes than in their homes in the woods, as I never 

 find this species on the trees before July ; and the same may be said of 

 some other species, though C. Ilea should probably be excepted. 



After one had moulted, at the last moult, I saw it turn, after its usual 

 period of rest, and eat the cast off skin. 



THREE MOTHS NEW TO OUR FAUNA. 



BY HV. EDWARDS. 



In my article with the above heading, to which my friend Mr. J. B. 

 Smith takes exception, I at once confess that an error occurs, and that 

 the title should have been new to "our lists" and not to "our fauna." Mr. 

 Smith wrote me a day or two after the publication of the paper, and I 

 at once replied that I should have used the word "lists" in the place of 

 " fauna." I am therefore somewhat surprised that in his printed remarks 

 he did not allude to the correction I had personally made, but that he 

 should take me to task after receiving my letter, and charge me with 

 adding the species mentioned to our "fauna," when I had disclaimed the 

 meaning he attributes to me. But though I am free to allow that the 

 species I spoke of may not with propriety belong to the U. S. fauna, I 

 am by no means willing to admit that they are on that account not deserv- 

 ing of a place in our Check List or Catalogue. This is, as I take it, not 

 a philosophic account of species belonging to a certain faunal district, but 

 merely the names of those species found to be inhabiting a geographical 

 limit, and is intended chiefly for the purpose of enabling collectors and
