Jleliotkis. — Numbers 1, 2, and 4, are from the cabinet of Mr. Bentley. No. 5 (H. scutosa) is from a Continental specimen in the British 

 iMuseuDi. Anarta. — Nos. 7 and 10 are from specimens from Mr. Bcntlcy ; 8, from a Continental specimen in the British Museum ; and 9 



(A. Vidua) from the specimen in the cabinet of Mr. H. Doubleday, one of the two specimens taken at the Shetland Isles. Acontia Fig. 12 



(A. aprica) is from Iliibner ; figs. 11 and 13 (Luctuosa and Solaris) .are from the cabinet of Mr. Bentley ; and 14 (Caloris) is from a Continental 

 specimen in the British Museum. Erastria. — All the insects figured in this genus, with the exception of E, minuta (No. 19) and E. ostriua 

 (No. 21), the former from a specimen in the British Museum, and the latter from Mr. Curtis's figure, reduced to the naturiil size, are from the 

 cabinet of Mr. Bentley. 



Mr. E. Doubleday, who has kindly e.\'amined all the insects figured in the genus Erastria, and caretuUy compared them with other specimens 

 in the Continental and British collections of the British Museum, has determined the insect called E. minuta in Mr. Bentley's collection 

 (Haworth's specimen) to be a North American insect ; the specimen in the British Museum (see fig. 2(1) being the true European minuta. 

 Mr. Bentley's E. albilinea (Haworth's specimen) he has also proved to be a North American insect ; and the insect figured by Mr. Curtis 

 (No. 21, in this plate) as E. ostrina, he thinks is very probably the E. purpurina of Duponehel, &c. iSic. 



The Caterpillars are from Htibner. H. N. H.
