A REVIEW, WITH SOME CEITIOAL NOTES, 



OP "THE PTEROPHORID^ OP NOETH AMERICA.

BY THE BIGHT HON. LORD WALSINGHAM, M.A., LL.D., F.R S., &c. 



Dr. Fernald has recently issued an excellent monograph of the 

 FterophoridcB of North America. Descriptions of all the genera and 

 species are published with synoptical tables and full synonymy, 

 moreover, it is accompanied by a good series of uncoloured plates, 

 representing the structural characters, especially the neuration of the 

 genera, and the male genitalia of a large number of species. It 

 would have greatly facilitated comparison if references to the figures 

 had been given in the text. The first ten pages are devoted to the 

 history of the family, wherein the more important literature of the 

 subject is referred to ; the structure, habits, early stages, systematic 

 position, and general chai'acters of these insects being set out in 

 detail.. 



The paper has been issued in separate form, but no reference is 

 given to the title of the original publication, and it is evident from a 

 reference to the index, wherein the page numbers run from 95 to 140, 

 that this excerpt of pp. 3 to 80 (including the pagination of the 

 plates) is not paged in accordance with the original publication. 



We cannot too frequently repeat the objections to such variation, 

 which is apt to cause the utmost confusion in tracing out subsequent 

 references given by other authors. 



Personally, I am very desirous to incorporate the references to 

 Dr. Pernald's paper in my MS. Index of the Pterophoridcs of the 

 World, but it is impossible to do so before obtaining a copy of the 

 publication in which it was issued. The editors must be held re- 

 sponsible for the issue of wrongly paged separate copies, which 

 cannot be regarded or cited as an independent edition ; but Dr. 

 Eernald may be acquitted of all blame for this unfortunate blunder. 



With regard to the systematic position of this family, the author appears to be 

 in sympathy with the view that it forms an aberrant group of the Pyralidce, as 

 suggested by Dr. Jordan, Ent. Mo. Mag., YI, 152 (1869), and his adoption without 

 reserve of the classification proposed by Meyrick, is no mean tribute to the accuracy 

 of that author whose methods and conclusions have thus received the sanction and 

 suppoi't of so high and painstaking an authority. 



His reference to the genus Chrysocorys, Crt, (more properly SchrecJcensteinia, 

 Hb.), p. 12, which had been placed among the PterophoridcB by several English
