chelus (Quince cur- 
culio) 
The square-shouldered 
brown beetles of Cono- 
trachelus crataegz were 
found puncturing the 
fruit of Crataegus for 
feeding and oviposition 
in July and August, 1918, 
and in late May and June, 
1919. The early months 
of 1919 were much 
warmer than those of 
1918 at Ithaca, and this 
probably is the cause of 
the great variation in the 
time of their appearance. 
The larvae develop within 
the haws, feeding on the 
pulp surrounding the 
large, stony seeds. A 
larva commonly eats

IN LEAVES OF CRATAEGUS PUNCTATA tire pulp of the fruit 
before emerging in the 
autumn, when it leaves the fruit by a large, round, exit hole. It then 
burrows down two or three inches in the soil and spends the winter as 
a larva curled in a smooth-walled earthen cell. In June, 1918, the writer 
found ninety-six larvae in the soil beneath one Crataegus punctata tree. 
Some of them pupated in June and others in July. They are very common 
on all the native hawthorns. 
nebulosus Lec., Anthonomus (Hawthorn blossom weevil) 
One of the most interesting and injurious of the insects found on the 
hawthorns is Anthonomus nebulosus, a member of a very destructive genus 
of blossom weevils. Its mode of life resembles in a general way that of 
the Mexican cotton boll weevil, A. grandis, and is almost identical with 
that of the European apple-blossom weevil, A. pomorum (Theobald, 1909: 
104-110). | 
The original description of A. nebulosus is to be found in the Proceedings 
of the American Philosophical Society (Leconte, 1876), and a more com- 
plete description is given by Dietz (1891). In the present account it is
