cillon.) Of the genus Orgyia^ I have three, if not four rspecies : 

 first, one close to our antiqua, wliich in fact might he mis- 

 taken for it; second, your No. 60, which varies a little in color; 

 third, a species closely allied to your 60, but of a uniform or 

 nearly uniform dark-broAvn ; it is from East Florida, and very 

 distinct from 60, though closely allied ; the two others are 

 from Trenton Falls. I have, too, a specimen taken at the 

 latter place, much Jarger than your 60 (it expands fully 

 Ij inches) and more highly colored, with a very plain white 

 patch near the middle of the costa. I feel sure from compar- 

 ing them again at the present time, that it is distinct. The 

 under surface is quite different from that of your 60. I have 

 not got Smith-Abbot's species ; may not this be their leuco- 

 stigma ? Perhaps they may have given that name to your 60, 

 from the small white spot at the inner angle. Besides these 

 four I have a small species from East Florida, possibly an 

 Orgyia. [60 Harr. mss. Catal.= Cladophora leucograpJia Hiibn .] 



In regard to torrefacta do you know of two species in the 

 United States ? I think that I mentioned to you that in 

 Abbot's drawings in the Museum, two closely allied species are 

 represented, one I think the same as Cramer's figure (of this he 

 gives the country as Surinam, I believe) ; the other I consider 

 the same as a specimen I took in North Carolina, a less showy 

 insect. The larva) of these are very different. They may be 

 tussocks, and I think now are not Notodontidce, 



I think velleda can hardly be a 3Iegaso7na, though I never 

 saw that genus. It is a most curious insect. Of the Olisiocam- 

 fee I have only one species, — mori ; I think as you do about it. 

 I never saw its wino-s closed en toil. 



Of the Dryocampce I have only ruhicunda, and the species 

 you have now with my other Bombyces. I have no Hepialus 

 from America. I think Gosse told me that one was common 

 in Canada with metallic spots, — your species I suppose. 



Have you compared the Georgian species I sent you of 

 Pygmra? gibbosa, with the Northern one. Abbot seems to
