the work of the insect in 1863 on the black alder, which is very 
susceptible to the attacks of the beetle. In Brehm’s “ Thier- 
leben”? Dr. E. L. Taschenberg mentions Cryptorhynchus lapathi as 
being the only European representative of a South American genus. 
‘Prot. F, M. Webster, in an article entitled “ The Imported Willow 
and Poplar Curculio,”’? states that there are now sixteen species of 
this genus inhabiting North America, north of Mexico, the majority 
of them being found in the south or southwestern states. Taschen- 
berg makes the statement that the adult only becomes injurious 
through its feeding on the leaves. Dr. Bernard Altum® states that 
near Eberswalde upon the Leuenberger Weisen, an outbreak of C. 
lapatht was controlled by the cutting out of the affected stems. Dr. 
Altum also reports that in the district of Schonlanke (Bromberg) a 
plantation which had given eighty cords of wood per acre was, 
ruined. A similar instance is reported from Weisbaden to the effect 
that about five acres of white alders were threatened with destruc- 
tion. The Danish writer Dr. I. E. V. Boas, in 1888, in an article 
entitled “An attack of the snout-billed Cryptorhynchus lapatht upon 
willows ” gives a short account of its habits and life history in Den- 
mark, and also mentions the devastation of a plantation of willows, 
Salix viminalis, grown for the purpose of making hoops. In 1897 
Dr. Freiherr von Tubeuf,* states, in effect, that, between Brenner- 
Post and Fenna, and also between eastern Arte and Brenner Bad, 
districts in Tyrol, Austria, the mountain alders presented a sickly 
appearance. Examination proved this was largely due to the work 
of C. lapathi, and that many of the trees were also attacked by a 
fungus Valsa oxystoma Rehm. ‘The injuries by these two agencies 
are similar in external appearance. 
HISTORY OF THE SPECIES IN THE UNITED STATES. 
Attention was called to the appearance of Cryptorhynchus lapathi 
in this country by William Juelich in 1882, who found the insect in 
the northern part of New York City.® Five years later the willows 
near West Bergen, N. J., were discovered to be infested, and in 
1891 Dr. J. B. Smith reported that in New Jersey willows were 
being killed by this insect. The beetle was found in injurious num-
