Mr. Smith said that he had placed naphthalin in boxes that were 
well infested with Anthrenus; this prevented development so long as 
any of the material remained, but after it all disappeared, which in 
one ease took over a year, the larvee developed.

BRIEF NOTES ON OHIO INSECTS FOR 1904. 
By HERBERT Ossporn, Columbus, Ohio. 
_ No particularly serious or widespread insect outbreaks have been 
noted in Ohio during the past season, but there have been a number 
of cases of local abundance and destruction, some of which may well 
be placed on record. 
The pear slug (Lriocampoides limacina Retz.) was noticed in 
Huron, near the lake shore, in small orchards of cherry trees, in 
which many of the trees were so seriously infested as to appear quite 
brown and burned. This condition was noticeable from a consider- 
able distance, and closer inspection of the trees showed the foliage to 
be almost completely destroyed by the numerous larve. This occur- 
rence was during the latter part of July, and at this time the larvee 
were apparently reaching maturity. | 
The willow weevil (Cryptorhynchus taputhi Linn.). Specimens 
of this introduced species have been handed to me by Prof. EK. H. 
_ Edwards, of Cleveland, who tells me that the insect occurred in large 
numbers on willows and probably also on poplars in the vicinity of 
Cleveland. Both larve and adults were observed and the damage
