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 large series in the National Museum collection 
recently received from Japan. 
Lyctus brunneus 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 mo lie) ; tayuya ( Trianospermia sp.), and yerba del lucera 
(Conyza sp.). 
There are records of the occurrence of the species in middle and 
southern Europe, Japan, Madeira, 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 species 
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. xvm, p. 154) as injuring supple-jack (a vine imported 
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 
effort 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 pectoralis 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- American a 
(Insecta Coleoptera, vol. v., p. 492), 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
