simulation of a stalk of a leaf, is very singular, as no tropical " leaf- 

 shaped" butterfly does it. In this respect L. celtis is unique. This 

 species inclines forward, stretches its palpi and antemne, touching with 

 them the leafless twig, and raises the anal angles of the hind wings." It 

 would be interesting to observe whether our species, Libythea bac/nnaiii 

 has this habit. H. SKINNEK. 



THE U. S. National Museum has obtained by purchase the Microlepi- 

 doptera of the collection of Anton Schmid and the collection of Dr. Ottmar 

 Hoffmann, with the exception of the Sesiidce, Psvchidie, Tortricidce, 

 Tineidse and Plerophoridoe of Hofmann's collection, which had been sold 

 te Lord Walsingham. The combined collections contain over 15,600 

 specimens in excellent preservation. All the species are of the European 

 fauna and give the National Museum an excellent representation of that 

 fauna, except in the Sesiidoe and Psychidae, which were taken from the 

 Hofmann collection and not included in the " Micros " of the Schmid col- 

 lection. The purchase was made through the kind office of Prof. A. R. 

 Grote, of Hildesheim, Germany. A notice of Anton Schmid will be 

 found in " Berichte des Naturw. Vereines in Regensburg," 1898 1899 and 

 Dr. O. Hofmann in the same journal, and also in the " Illust. Zeitschr. 

 fiir Ent.," V, 140, 1900. HARRISON G. DVAR.

Under the above head it is intended to mention papers received at the Academy of 

 Natural Sciences of Philadelphia pertaining to the Entomology of the Americas (North 

 and South). Articles irrelevant to American entomology will not be noted. Contribu- 

 tions to the anatomy, physiology and embryology of insects, however, relating to Ameri- 

 can or exotic species, will be recorded. The numbers in HEAVY-FACKD TYPE refer to the 

 journals, as numbered in the following list, in which the papers are published ; * denotes 

 that the paper in quest ion contains descript ions of new North American forms. Titles of all 

 articles in foreign languages are translated into English; usually such articles are written 

 in the same language as the title of thejournal containing them, but when such articles are in 

 other languages than English, French, German or Italian, this fact is indicated in brackets.
