thing has been observed in this country, and the specimens taken 

 in March and April have, I believe, always the appearance of 

 hybernated specimens. Several specimens of semiaurella were 

 beat out of fir-trees at West Wickham, by Messrs. Douglas and 

 Bedell at the end of March this year (1848).

This is the Clerckella of the Linnean Cabinet. 



" Certainly distinct from the preceding ; larger, and distin- 

 guished by the oblique brown dorsal streak, curved posteriorly, 

 on the anterior wings, and the entirely differently-coloured apex 

 of the wing." 



" Scarce, but widely dispersed ; I took one on the 7th of Au- 

 gust in a garden at Berlin, one near Glogau on the 7th July, on 

 a fence, and one on the 29th July, on the Keinerz Seefeldern, 

 (salt marshes ?) where, as far as I know, no Prunus grows." 



" Sp. 3. PadifoUella, Hiibn." Linn. Ent. vol. 3, p. 261. 



This species is described by me in the "Zoologist," p. 2160, 

 under this name; it is taken in the autumn at Whittlebury. It 

 appears much rarer on the continent ; Zeller had only seen four 

 specimens, and states that he was greatly in doubt whether it was 

 not a variety of f)'''W)nfoliella, in the same way as csreella, Tr. is 

 of Clerckella. 



" Mann took several specimens in June, 1835, near Reichstadt 

 in Bohemia, on Prunus padus ; in the Prater, near Vienna, in July, 

 on elms." " Bouche bred it in Berlin from birch leaves."

" This species, of the size and form of the preceding, only with 

 the anterior wings rather broader, is distinguished by the want of 

 distinct markings, particularly by the pale apex of the wing." 



" The specimen in Fischer's Collection was from Bohemia ; that 

 now before me, from Mann's, was taken alone on an ash at Tivoli, 

 near Vienna, in June, 1842. Both specimens are males." 



In Zeller's genus Pliyllocnistis he has only two species, both 

 probably occurring in this country.
