LETTERS FROM DR. HARRIS. 193 



specimens of the European Z. Geltis^ the figures of which 

 your species strikingly resembles; and when my specimen 

 was captured, finding it to differ in size and in colors 

 beneath, from Abbott's figure of Z. Motya^ in Boisduval's 

 Hist, et loonogr. des Lepidoph. de VAmer. Sejyt., pi. 64, 

 (unaccompanied by a description,) I thought mine must be 

 the European species, introduced somehow with foreign 

 trees, more especially as Hovey's Nursery, containing many 

 trees from France, and Mr. Oushing's elegant place, also 

 having many foreign imiDortations, are not very far from my 

 residence. 



Abbott figures Z. Motya or Celtis occidentalis. I think 

 it must be rare in Georgia and at the South, because I have 

 never received it from the South, and because Abbott has 

 not figured it in his Lepidoptera of Georgia, nor in a consid- 

 erable collection of original drawings of his, which my 

 friend Doubleday purchased for me in London. As your 

 species is common in Wisconsin, you may hereafter have 

 numerous specimens from thence, through your friend Dr. 

 Hoy. You will then be better able to determine whether 

 it be identical either with Z. Motya or Z. Celtis. Mean- 

 while I will hunt up good figures, if possible, of Z. Celtis., 

 and compare your and my specimens therewith, and let you 

 know the result. 



Since writing the above, I have been looking for figures 

 of L. Celtis. The volume of Godart and Duponchel, Hist. 

 Lep.., France, containing this species, is out of the Library, 

 and I cannot find any better figures than those in the 

 Archives of Fuessly, Tab. 8 and 14. There is considerable 

 disparity in the sizes of the specimens (sexes?) there repre- 

 sented, but in none of them are the tawny orange markings 

 exactly like those.' of our species, nor are there so many 

 io^*i{^_ spots on the fore wings. Our species approaches to 

 L. Carinenta., Cramer, from Surinam, but it is not near so 

 large. I doubt the accuracy of Abbotfs figure of L. Motya, 

 and only one sex is represented. Perhaps the other sex
