Denuding the Wings of Lepidoptera. — Put the wing in alcohol; then 

 into a saturated solution of chloride of lime, leaving there until the colors are 

 pretty well faded. Have an ordinary microscopic slide at hand with two or three 

 drops of pure water on it, somewhat spread out. Take the wing out of the 

 chloride of lime and put in carbolic, or dilute hydrochloric acid, leaving only a 

 moment; take out and put in the water on the slide. Carefully put it in the shape 

 you wish, which in the water can be done without difficulty. Touch the edge 

 of the water with blotting-paper till it is about drained oft"; then put the blotting- 

 paper flat on the slide, wing and all, thoroughly drying it. On taking up the 

 paper the wing will remain on the glass; slightly dry over a lamp, brush off" the 

 wing lightly with camel-hair brush to remove dust, etc.; put on Canada Balsam; 

 heat a little and put on a microscopic cover, sufficiently large; let it dry as any 

 ordinary slide with mounted object. You have then the wing perfect, entirely 

 transparent and in a permanent form. Legs and other parts of insects can be 

 treated in the same way. I have had little satisfaction with pasting the wings 

 in a book after bleaching; the wings are rarely well spread, and are easily broken. 

 The above method is very satisfactory to me. Geo. D. Hulst. 



LiMENiTis Eros, Edw. — Mr. Strecker, in his Catalogue, indicates Floridensis 

 as a variety of Disippus: " The form found in Florida and other parts of the 

 extreme .South." That applies to the mahogany-colored form of Disippus, of 

 which I have several e.xamples, but it does not define Eros. That species, among 

 other points, is characterized by a white median band not found in Disippus, 

 and nothing was said of that; I had no idea that Eros was what Mr. Strecker 

 had in mind. Now it is a rule that, where two species are confounded under one 

 name, the author who di.sei\tangles them has a right to apply the first name to 

 either, and his nezu one to the one he pleases.. Mr. Strecker published to the 

 world that I had encroached on his manor (Can. Ent. vol. xiii, p. 29), but Mr. 

 Mead in the same volume (p. 79) gave the sense of the New York Entomolog- 

 ical Club that the name Eros, under the circumstances, was properly given by 

 me and should hold. The rules of Entomological Nomenclature are decided as 

 to the definition of species required to give priortty. "Unless a species or 

 group is intcttioibty defined when the name is given, it cannot be recognized by 

 others." (Remarks under Rule 11.) W. H. Edwards. 



Pamphila Cernes, Bd.-Lec. versus Manataaqua, Scud. — I would be glad 

 to receive any information of the geographical range, dates of appearance, etc., 

 of either, or both of these forms, that the readers of Papilio may be able to 

 afford me. I shall consider myself under lasting obligations to any one who can 

 tell me how these forms may, zvith certainty, be separated. I have always con- 

 sidered Dlanataaqua a variety of Cernes, at best, but have come to the conclu- 

 sion that the intergrades outnumber the typical specimens of either form, and 

 that, therefore, it is not even entitled to that rank. I hope to be able to throw, 

 some light on the subject by breeding them this summer, and should be glad to 

 receive information as to their pre-imago habits, etc. E. M. Aaron.
