NEW BRITISH SPECIES SINCE 1835. 37 



tingnished from it, frequents poplars. Guenee says — " The 

 larva lives in the buds of the poplars, and is almost as 

 abundant as that of gilvago is on the elms/' 



Gortyna Petasitis, Doubleday ; first recorded as cap- 

 tured in this country by myself (Zoologist for 1846, page 

 1229). A notice of its habits by Mr. Edleston appears in 

 the Zoologist for the same year at page 1347. It frequents 

 the butter-bur, Tussilago Petasites, the larva feeding in the 

 root of that plant, as observed by Mr. N. Cooke in the 

 Zoologist for 1850, page 2932. The species was first de- 

 scribed by Doubleday in the Zoologist for 1847, page 1914, 

 and since has been described and figured by Freyer and 

 Herrich-Schaffer under the name of Vindelicia. Since the 

 northern collectors have learned to breed the species it has 

 become generally distributed in collections. 



Caradrina exigua, Hiibner; first enumerated as Bri- 

 tish in Doubleday's Catalogue, at page 27. A specimen taken 

 by Mr. Maitland at Ventnor is in his collection. 



Hydrilla palustris, Hiibner; a specimen taken near 

 Yoi'k is in the collection of Mr. Allis. Apparently a scarce 

 continental species, occurring, according to Guenee, "in 

 South Russia, Austria, the Valais, in May and July." 



Nonagria extrema, Hiibner; first enumerated as Bri- 

 tish in Doubleday's Catalogue, at page 27, the species named 

 extrema at page 7 having been ascertained to be resUyjulva. 

 It has occurred in some numbers at Whittlesea-Mere in 1848 

 and 1849, and is in most collections. It is at once distin- 

 guished from j\ r . fuha and N. Hellmanni by the straight 

 hinder margin of the bone-white anterior wino-s. Guenee 

 describes it under the name of N. concolor, conceiving it to 

 be distinct from the extrema of Hiibner, though probably 

 identical with the extrema of Herrich-ScharFer. 



Nonagria Hellmanni, Eversman; the capture of this 

 species in this country is first recorded by Mr. Bond in the
