A note off Zygaena. 



J Bj' John B. Smith, Washington. 



In the Transaction American Entomological 

 Society 1885, v. 12, pp. 77—84, I gave some 

 notes on the structure and systematic position of 

 some of the genera and species which in Ameri- 

 can Lists are loosely classed as Zygaenidae. In 

 these notes I used the European genera Zygaena 

 and Ino as types of the family and of course 

 gave a summary of their characters based on my 

 own examination of the species. Among other 

 things I also figured the neuration of one of the 

 common species of Zygaena — I really forget 

 which — and stated that where.^s Ino has three 

 inèternal or çnree veins to the secondaries, Zy- 



' gaena has only two, and my figure so shows it. 

 In a generally appreciative notice of this paper 

 by Mr. H. B. Moeschler in the Stettinjer Entom. 

 Zeit, he calls attention to this supposed inaccuracy 

 of my figuçe, and considers it curious that my 



\ text shoi^d agree with it. Since that time I 



I have had no special occasion to refer to the 

 matter, but I wish to call the attention of Euro- 

 pean Lepidopterists to the matter now. I do most 



..positively state, in opposition to all the previous 

 authors I am acquainted with, that where '^as 

 Ino has three distinct internal veins to secon- 

 daries, Zygaena has certainly but two in all the 

 species I have examined. The so-called third vein 

 is a mere fold and not a vein at all. The Pyro- 

 morphidae also have three very distinct internal 

 veins. 



My method of examination was to bleach the 

 wings in chloride of lime or render them, trans- 

 parent by carbolic acid, and afterward mount on 

 a slide in Canada balsam. This brings out all 

 the peculiarities of the venation distinctly. I can 

 hardly believe that my specimens were peculiar, 



and it seems difficult to believe that all the Le- 

 pidopterists who have heretofore examined the 

 subject should have made the same mistake. 



M'^ill not some of my European colleagues 

 examine the species carefully, and give us the 

 result in the „Societas entomologica".
