17. Cressonia juglandis, Smitli. — This well-known insect has been 

 taken as the type of a new genus, worthily dedicated to Mr. E. T. Cresson, 

 Philadelphia, by Messrs. Grote & Kobinson (Pro. E. S. Phil. v. 186). Its 

 structural differences from the other species of Smerinthus appear to fully 

 warrant its separation from them. 



18. Macrosila qutnquemaculata. Haw. — The transference of this and 

 several other American species to Boisduval's genus from that of Sphinx was 

 made by "Walker (C. B. M. viii. 198), and has since been concurred in by 

 Clemens and Grote. 



19. Daremma undulosa, Walk. — This species has given rise to an 

 extraordinary amount of confusion and difficulty. Mr. Walker himself has 

 stated (vide Pro. E. S. Phil. v. 189), that " this species is a mistake ; it has 

 been newly identified as a dwarfed and slightly aberrant specimen of Sphinx 

 brontes." The specimens, however, from which he described his M. brontes, 

 Drury, "differ much from Drury's figure, and may be a distinct species" (C. 

 B. M. viii. 199) ; they have since proved to be Dr. Clemens' Ceratomia 

 repentinus, yihich. insect Grote & Bob. consider structurally distinct from the 

 other species of Ceratomia. The question now is, what name is this unfor- 

 tunate insect to bear ? The last named authors (Trans. E. S, ii. 76) go back 

 to Daremma undulosa ; with all due deference we should say D. repentinus 

 would be the more just designation, being Walker's genus and Clemens' 

 species. 



20. Ceratomia amyntob, Hiibn. — This specific name appears to have 

 the priority over Harris' C. qttadrtcornis. 



21. Sphinx eremitus, Hiibu. — This is the S. sordida o( Harris; the 

 former name has the priority. 



22. Sphinx chersis, Htibn. — The S. cinerea of Harris.
