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 antennae, 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 bachmani 

 has this habit. — H. Skinner. 



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

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

 Hoflfmann, with the exception of the Sesiidae, Psychidae, Tortricidae, 

 Tineidae and Pterophoridae of Hofmann's collection, which had been sold 

 to 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 Sesiidae 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 " lUust. Zeitschr. 

 fiir Ent.," V, 140, 1900.— Harrison G. Dyar.
