pine from Europe, the import trade in this stock since 1909 has been 

 reduced to a small amount. In the years 1910 and 1911 only a very 

 few shipments are known to have come into the country from the above 

 mentioned nursery. Diseased shipments have, however, been received 

 from three French firms, thus showing the danger from importations 

 from any European country. The disease has an incubation period 

 during which it cannot be detected by the most skilful plant patholo- 

 gist. Because of this incubation period, which is of indefinite length, the 

 only feasible plan of handling the situation seems to be the prohibition 

 of the importation of white pine, and of other five-leaved pines, which, 

 so far as we know, are also susceptible to the disease. P. S. 



ENTOMOLOGY.- — Descriptions of Tineoid moths (Microlepidoptera) 

 from South America. August Busck. Proceedings U. S. National 

 Museum, 41 : 205-230. Plates 8-9. 1911. 



The material is from the collection of Mr. Wm. Schaus and almost 

 wholly from French Guiana. Forty-five species and the following five 

 new genera are described: 



Filinota, related to Carcina; Hasta, allied to Anchinia; Gonada, near 

 Necedes; Ordrupia, similar to Hemerophila; and Plumana, based on a 

 male much like Fumea. Twenty-three of the new species are in the 

 genus Stenoma. The plates are photographs and do not well illus- 

 trate the moths. N. Banks. 



ENTOMOLOGY. — Bees in the collection of the U. S. National Museum. 



T. D. A. Cockerell. No. 1. Proceedings U. S. National Museum, 



39: 635-658. 1911. No. 2. Ibid., 40: 241-264. 1911. 



In these two papers Professor Cockerel] describes new species of bees 



from the United States and Oriental Asia. There are notes of value on 



many of the described species and frequently closely allied forms are 



separated by synoptic tables. In the second paper there is a table to 



the Asiatic species of Anihophora. There are no new generic names 



but new characters are given to distinguish Viereckella from Melano- 



nomada, both really subgenera of Nomada. N. Banks.

 Texas, with descriptions of new genera and species from Texas, Ari-

 In the isolated humid spots, now containing certain peculiar milli- 

 pedes, the author sees evidence of the existence of former forests in
