THE CANADIAN ENTOMOLOGIST. 183 



the Chicago Academy Transactions, in which the description appeared, 

 was destroyed in the Great Fire, and that Dr. Packard in consequence 

 regarded his paper as unpubHshed. The species Leucophcea Neinnoegeni^ 

 Hy. Ed., belongs to my genus Argyrmiges, Can. Ent., XIV., 215, and 

 is in my opinion sufficiently structurally distinct from Hetnileuca Maia 

 and allies, a genus in which the common pattern and antennal colour 

 and structure show that the forms have become but recently separated 

 and hardened into species, as seems to be the case with Datana, and, 

 perhaps, Clisiocampa and Platysamia. A. R. Grote, 



Dear Sir : I wish on behalf of the Entomological Society of Ontario, 

 to make public acknowledgment of the eminent services rendered to it, 

 and the lasting benefit conferred on the Canadian members of it especi- 

 ally, by Professor C. H. Fernald, who has reviewed the Society's entire 

 collection of Pyralidse and Crambidas, at a great expenditure of labour and 

 valuable time to himself, and with no hope of reward, except the con- 

 sciousness of having performed an enduring work for the advancement of 

 our science. I forwarded to the Professor, at his own suggestion, the 

 Society's drawers containing these insects, and a box of duplicates, that 

 he might see just how they stood in regard to nomenclature. In due time 

 they were returned, preceded by a communication indicating that they had 

 received the closest scrutiny, pointing out errors, and conveying informa- 

 tion which enabled me to bring the collection into harmony with his recent 

 revision of these families^ as published in Prof. J. B. Smith's " List of 

 Lepidoptera of Boreal America." The most important of the errors 

 corrected, which may have spread from this to other collections, are two : 

 What was under the name Cr ambus prcefeciellus, Zink., proved to be 

 C. Leachellus, Zink., and what was under the name of C. sericineilus , 

 Zell., he pronounced to be but rubbed specimens of C. albellus, Clem. 



The Professor kindly sent to me an example of C. i?motateiltis, Walk., 

 of which sericinellus is a synonym, that I might see what it was like ; it 



was a species that I had not seen before, and may not properly belong as 

 yet to our list, and the same is possibly true oi prcefedellus. 



We have now a collection in these families which may be pronounced 

 a correct standard for comparison and identification as far as it goes, and 

 the guarantee for its reliability is the work done upon it by Professor 

 Fernald. All our members are cordially invited to make use of it. 



J. Alston Moffat, Curator.
