148 Mr. J. W. Dunning on 



The A. hadensls of Nolcken, of which I have seen a 

 male sent by Reutti to Stainton, is the insect given as 

 niveus by Heinemann, who treats Nevce as identical 

 therewith ; and as the only locality mentioned by Mil- 

 liere for his A. niveus is the Lake of Constance, I should 

 have thought that his fig. 20 represented badensis, but 

 according to Staudinger and Wocke it represents A. 

 germanicus, if not a " species diversa/' distinct (I sup- 

 pose) not only from germanicus and hadensis, but from 

 Nevce also. As to hadensis, Nolcken says, " the female 

 has short rudiments of wings, so that this species cannot 

 be identical with the English species, which has a wing- 

 less female ; " we have seen that many of the English 

 females have short rudiments of wings, but on this point 

 I refer back to what I have said under the head of Gar- 

 nonsii and Hansoni. He also remarks that the absence 

 of the long hairy fringes of the hind tibiae (for he cannot 

 believe that Heinemann would have overlooked them) 

 distinguishes it from the English species ; but the cadu- 

 city of these fringes has already been referred to, and 

 doubtless Heinemann does not mention them for the 

 same reason that every author except Brown has omitted 

 to mention them. Lastly, Nolcken says that the absence 

 of the two teeth on the hind-tibiae of the male distinguish 

 it from A. Nevce, but as he himself, like everybody else, 

 has been unable to discover these teeth anywhere but in 

 Kolenati's figure, it is rather too much to adduce their 

 absence as a proof of the distinctness of badensis. And 

 as Staudinger and Wocke do not consider badensis 

 entitled to specific rank, I think we shall not go far 

 wrong in agreeing with them on this point. 



The A. germanicus of Nolcken, from Pomerania, must 

 be the insect which Zeller had in numbers (Stett. Zeit. 

 1867, p. 192) without its occurring to him that it was 

 specifically distinct, and as Nolcken gives no reason for 

 regarding it as distinct, I again agree with Staudinger 

 and Wocke in refusing it specific rank. I am unable to 

 make out why Staudinger and Wocke consider Milliere's 

 niveus to be Nolcken's germanicus, and not badensis. 



There remains only A. latipennis, of which Knaggs 

 has lent me a continental pair ( cJ and ? ) sent to him 

 by Staudinger. Moschler himself says, that A. latipennis 

 " cannot easily be distinguished from A. niveus : " the 

 only distinctions which I can gather from his description
