116 THE CANADIAN ENTOMOLOGIST. 



by Professor Fernald, who is our authority on the TortricidcE without a 

 rival. And this position is not an easy one to gain. The little delicate 

 insects are very variable, and in the genus Teras, for instance, they change 

 pattern and colors like a kaleidescope. The genera, as in the Deltoids? 

 Phycids, etc., have to be limited by characters offered by the males alone, 

 quite often, and in all cases the entire structure has to be carefully noted 

 in order to locate the species to the best advantage. 



All the requirements have been met, and, as a proper conclusion to 

 his labors so far, a breathing place where one can survey the road travelled 

 over. Professor Fernald gives us his very useful Catalogue. Having our- 

 selves written a synonymical Catalogue of the Sphitigidce, we have a lively 

 sense of the work to be performed in a Family yet more numerous in 

 species and more intricate in synonymy. The student can, however, use 

 Prof Fernald's Catalogue with the certainty that it is as accurate as it can 

 be made, and he will be very unappreciative if he feels no gratitude to 

 its accomplished author, who has spared no labor in completing his self' 

 imposed task. Professor Fernald, by his moderate views and careful 

 methods, has proved himself a safe guide ; at the same time he has shown 

 himself possessed of talents which carry him easily in the front rank 

 among living Entomologists. It would be well if such proofs as Professor 

 Fernald has offered of knowledge of the subject were demanded of all 

 writers of Lists and Catalogues ; but I will not pursue this view of the 

 subject any further, nor burden a proper praise of Professor Fernald with 

 remarks which he is too amiable to sanction. 



MR. S. H. SCUDDER'S NOMENCLATOR ZOOLOGUS. 



BY A. R. GROTE. 



Science is much indebted to Mr. Scudder for a great deal of very dry 

 and tiresome work in the preparation of Catalogues. We have already 

 from his pen a list of the generic names used for Butterflies, and now in a 

 thick octavo volume of 376 pages we have a "list of generic names 

 employed in Zoology and Palaeontology to the close of the year 1879, 

 chiefly supplemental to those catalogued by Agassiz and Marschall, or 

 indexed in the Zoological Record."
