There appear to be two closely allied species known as the 

 P. albifrons, one much smaller than the other. Of this more 

 in a short time. The Centra from the cabinet of the Entomo- 

 logical Club is figured by Abbot in his drawings with the larvae, 

 of which I will send you a tracing. I much doubt whether the 

 beautiful Pyralidiform insect from Georgia is allied to Notodonta. 

 It is figured by Abbot without a larva. 



I found in the Museum, a few days since, some specimens 

 of Melitcea Ismeria, collected by Abbot. It is nearer M. Tharos 

 than Boisduval's plate would lead you to imagine. We have 

 there a specimen of an insect I much want to get, and which I 

 had fancied quite a Southern one, Polyommatus Tarquinius. 

 Our specimen was taken in Nova Scotia by Lieutenant Red- 

 man, who sent a vast number of insects thence to the British 

 Museum. This reminds me that I am now quite convinced that 

 pseudarr/iolus of the North is not pseudart/iolus of the South. 

 There are two species. To which does the name belong? 

 Boisduval's plate will not distinguish them. 



I hope to go to Paris this autumn, or it may be sooner, and 

 shall take all my North American Theclce (thirteen species, 

 I think) and Hesperice (about thirty species) to Boisduval, and 

 if you think it worth while will take yours. Do you like to 

 risk them ? I would gladly take charge of them for you. 



I find in the British Museum a large number of the true 



o 



Aryynnis Aphrodite, as named by Fabricius in the Banksian 

 Cabinet. I have a fine series of varieties of Cybele Fabr. (as 

 named in the Banksian Cabinet), varying in size and in the 

 color of both surfaces, but in all the distinction from Aphrodite 

 is quite clear. The Museum specimens were presented by 

 Redman of Nova Scotia, but I hope to be able to get you one, 

 though we have some trouble in giving away or exchanging 

 specimens presented. 



Newman was the author of the papers signed " Rusticus," 

 though he sometimes pretends to deny it. Hadena arnica 

 Steph., is your American moth, and is not H. arnica Ochs. 

 The specimens reputed British are of Abbot's collecting.
