Accordinaf to Dr. Luudbeck, only two specimens, both (^ (^ , have 

 been taken in Denmarlv (June, 1910), and it is only known elsewhere 

 from Styria and Hungary, so that its occurrence in Scotland is 

 interesting. 



Perhaps I may l)e allowed to point out tliat in the figure of the 

 front leg of H. aironetha (Dipt. Danica, 3, p. 162), the tarsus is repre- 

 sented as consisting of six joints.

[This species also occurs in England, specimens having been taken by Mr. 

 Verrall near Leith Hill (Surrey) in June, 1868, and at Tunbridge Wells (Kent) 

 in June, 1886.— J. E. C.]. 



NOTE ON JOHN CUETIS' BEITISH ENTOMOLOGY, 

 ^ 1824-1839: 1829-1840: and 1862.

The book consisted of sixteen volumes of twelve parts each, = 192 

 parts. There were 770 plates (1-769 and 205* duplicated for Hippar- 

 chis arcanius) each (first edition) with two pages of text. 



Parts one and two had five plates each (plates 1-10) : parts 3-59 

 four plates each (plates 11-238) : part 60 had four plates (plates 239 ■ 

 241 and an extra plate and text 205* for Hipparchia arcanius) ; parts 

 61-192 four plates each (plates 242-769) : total 770 plates. The break 

 in part 60 of three consecutively numbered plates, instead of four, 

 throws out one's calculations, but the total number of plates is re- 

 adjusted by the additional plate 205.* 



One number a month was issued with great regularity, com- 

 mencing January 1824, and finishing December 1839, so the dates 

 on the plates may be accepted with certainty. In the Entomological 

 Magazine, i, 1833, p. 303, it was announced that the British Ento- 

 mology would appear in alternate months in double parts, and this 

 arrangement seems to have begun with parts 109-110, and is noticed 

 to continue to parts 117 and 118. We have also wrappers for 159 and 

 160, and 169 and 170, but one may conjecture this to have been an 

 irregular proceeding, for the Linnean Society of London received most 

 of the parts separately from Curtis himself, as seen by the Donation 

 Book of that Society, itself a most valuable record for many works. 

 We do not therefore think that there is any need to distin-b the dates 

 given on the plates, at this distance of time, for the sa.ke of a few odd
