having been captured in England, quite as frequently as A. niveus. I am 

 quite in accord with Bitsema when he says that A. Hansoni, Garnonsii, 

 Neves, badensis, and germanicus are not specifically distinct from ^.niretts; 

 but I go a step further, and say that A. latipennis is identical with A. 

 Hansoni. 



With reference to A. ohscurus, Ritsema appears to think that Tengstrom 

 described it as a new species, and that Wocke has reduced it to the rank 

 of a variety of A. Nene; the fact is, however, that Tengstrom never 

 regarded A. ohscurus as anything more than a variety of A. Nevoe, and he 

 expressly described it as such. 



Ritsema expresses surprise that Staudinger and Wocke have not adopted 

 the name Acentropidw for the family ; but when the derivation of the 

 word Acentropus is remembered, it is at once seen that there is no ground 

 for surprise, and that the change of Acentropidae into Acentropodidce is 

 only in accordance with the orthogi-aphic system which Wocke has fol- 

 lowed throughout his part of the Catalogue. For instance, the familiar 

 Pyralidcc have on the same principle been converted into the Pyralidid^. 

 Staudinger on the other hand has retained the familiar Pieridce, which, 

 had it occurred among the Micro-Lepidoptera, would, I suppose, have 

 been written in its correct form of Pierididce.
