It is somewhat doubtful whether this species is entitled to be added 

 to the list of Coleoptera common to Europe, North America, and north- 

 ern Asia, as its naturalization in this country has not yet been estab- 

 lished. Zoufal gives the distribution simply: Europe, Asia, North 

 America. There is a larj^e series in the National Museum collection 

 recently received from Japan. 



Lyctus hrunneus Steph. — The Lyctus mentioned as number 31 in the 

 list has been identified by Dr. Sharp as the above species. A compari- 

 son of this with our North American representatives of the genus shows 

 that it is distinct. 



At the Exposition it was found in several jars of rhizomes and roots 

 in the Paraguayan exhibit, of which the following bore labels: Pepper- 

 tree {Schinus molle) ; tayuya {Trianoapermia sp.), and yerba del lucera 

 [Conyzu sp.). 



There are records of the occurrence of the species in middle and 

 southern Europe, Japan, jMadeira, and the West Indies, but it is not 

 known to occur in the United States. 



Lyctus unipunctatus Hbst. {canaliculatus Fab.) — Mr. Schwarz has 

 called my attention to the identity of this European species with the 

 Lyctus striatus Melsh. of American collections. In Europe the si)ecies 

 is widely known, but from the fact that considerable confusion has 

 always existed in regard to the identity of the various North American 

 representatives of the genus, the distribution of this particular one in 

 America has not been defined. 



Specimens of the Lyctus mentioned by Dr. Hagen in the Canadian 

 Entomologist (vol. xviii, p. 154) as injuring supple-jack (a vine imi)orted 

 from Jamaica and used as walking-sticks) are in the collection of Messrs. 

 Hubbard and Schwarz, and are of this species. The beetles, Mr. Hub- 

 bard informs me, continued at work in the supple-jack, in spite of every 

 eflfort to eject them, for about fifteen years, and until the entire lot was 

 "powder- posted" and completely ruined. 



In local collections the species is represented from Massachusetts^ 

 New York, Ohio, Iowa, Michigan, North Carolina, Texas, California, 

 and the District of Columbia. 



Spermophagus pectoraUs Sharp. — The bean-weevil mentioned in the 

 list at number 49 has been identified by Dr. Sharp as the above- 

 mentioned species. It is described in Biologia Centrali-Americana 

 (Insecta Coleoptera, vol. v., p. 402), and the distribution given is: 

 Mexico, Guatemala, Nicaragua, and Panama. At the Columbian 

 Exposition it was also found from Brazil. As it breeds like our com- 

 mon bean-weevil for successive generations in stored beans, and is 

 congeneric with several species native to the United States, its intro 

 duction is to be feared. A supply of the beetles and of the infested 

 beans that were brought to Washington from the Exposition failed to 

 survive the winter; but no great significance attaches to this, as I have
