NEW BRITISH SPECIES IN 1857. 87 



Aspilates Sacraria, Linnaeus. 



This conspicuous insect with the anterior wings of a 

 sulphur yellow, with an oblique purple streak from the apex 

 to the middle of the inner margin, and with the posterior 

 wings quite white, has been recorded (see Intelligencer, vol. 

 3, No. 57, p. 36) as occurring at Plymouth. Future investi- 

 gation must show whether this has been an accidental impor- 

 tation, or whether the- species has any claims to be considered 

 truly British. 



Mr. Wollaston remarks, * that all the species common to 

 Madeira and the British islands are found in the south 

 western extremity of our country and of Ireland ;" the occur- 

 rence of a Mediterranean species would therefore be more 

 probable in that portion of Great Britain than elsewhere. 



The occurrence of the insect in Sweden was recorded by 

 Thunberg, in 1784. 



It will be remarked further on, that one of the Plumes 

 first taken at Rhodes, and subsequently in Italy, but not 

 known as occurring in Central or Northern Europe, has been 

 this season met with on the Lancashire coast. 



As the capture of Mr. Rogers' specimen in September has 

 been considered very extraordinary, it is interesting to know 

 that Mr. Wollaston took this insect in Madeira at the end 

 of September. 



Eupithecia Helveticaria, Boisduval. 



This is not very closely allied to any other species. Her- 

 rich-Schaffer places it next to Satyrata, and Boisduval puts 

 it in the immediate vicinity of that species ; it has, however, 

 the wavy lines more distinct, and the black spot is as distinct 

 as in Absinthiata, only placed more obliquely. The anterior 

 wings are rather broad. 



I am strongly disposed to think that Freyer's Arceuthata
