somewhat rounded blackish spot within ; a subterminal series 

 of interspaceal black maculations continued distinctly to costa. 

 General color dull olivaceous. Described by me originally 

 from Cuba under the name Lycaon, but differing from that 

 species according to the British Museum collections. Food 

 plant and larva unknown. Another West Indian species is 

 described by me in the Bulletin of the Buffalo Society of 

 Natural Sciences the type of which is contained in Agassiz *) 

 Museum, Cambridge. 



Pandoras. Hiibn. (Satellitia Harris.) This species 

 inhabits Canada and the Northern parts of the United States 

 and differs specifically from the South American P. satettitia 

 of Linnaeus. Pale greenish, marked with spots of rich olive 

 green. The forewings have a large olive green spot on the 

 middle of hind margin and a triangular spot of green rests 

 on the hinder margin just within anal angle, while another, 

 more diffuse, rests on costa a little within the apex ; the 

 wing is crossed by various shade lines and the veins are 

 partly marked with ochrey, a character often escaping notice. 

 Hind wings with a dark brown spot near hind margin and 



*) During the life-time of this distinguished Naturalist and most success- 

 ful lecturer and teacher, I was invited to study the Sphingidae in the 

 Museum, hut was unahle to visit Cambridge at the time. The collection 

 there contains hut two or three of my types, sent me long afterwards 

 for study to Buffalo. My letter from Prof. Louis Agassiz was as follows : 



Cambridge, Dec. llth. 1866. 

 Dear Sir! 



In absence of Mr. Uhler, who may however return in a few days, 

 I cannot say whether the collection of Sphingidae and moths are likely 

 to be sufficiently extensive in your estimation to justify you in coming 

 to Cambridge to work them up. Meanwhile I would say that if you 

 decide to come I shall give you every facility I can for your work. I 

 would be glad to see that part of our collections worked up. My son 

 has already written to you what the rules of our Museum are; so I need 

 add nothing upon this point. Mr. Uhler could give you more accurate 

 information than I can concerning your arrangements here. 



Very respectfully yours 

 (.Signed) L. Agassiz.
