wasp cuts its way from the egg shell with its mandibles. The time required for the 
process in one case was thirty-five minutes from the time the first puncture of the egg 
shell occurred until the wasp emerged. Where there are more than one wasp in 
the egg, the second wasp sometimes enlarges the exit hole before attempting to pass. 
As soon as the wasp comes forth and while the wings are still pads, it can jump an 
inch with alacrity. The wings fill out in about four minutes. The parasitized 
egg first turns brown, then shining black. The parasite emerges through a ragged 
circular hole about one-fourth the diameter of the egg blister while the slug in hatch¬ 
ing comes through by making a large crescentic rent in the shell. It is thus possible 
to include the abandoned eggs in the counts for parasites.

Rice Weevil. It has been known that the rice weevil, Sitophilus oryza, can cut 
holes through shuck coverings of corn. These holes, however, appeared to be made 
chiefly in storage. During early December 1922, the writer observed weevils in the 
field cutting their way out through a relatively tight fitting shuck covering. A slight 
opening at the tip of the ear had permitted the entry of a weevil which had penetrated 
to the base of the ear where it had evidently deposited numerous eggs. The second 
generation of adults upon emerging from the kernels found themselves confronted 
with a closely applied shuck covering through which they proceeded to cut their 
way to the outside. Upon reaching the more loosely fitting outer leaves of the shuck, 
certain of the weevils crawled unobstructed to the tip of the ear and thus gained 
freedom, but others much closer to the base were forced to cut their way through 
each layer of the shuck covering before leaving the ear.

Rhagoletis tabellaria Fitch. What appears to be a new record for this insect is 
the finding of the larvae in the fruit of the Western Tall Blueberry in western Wash¬ 
ington. On August 15, 1918, while making a trip by automobile from Aberdeen to 
Markham, Wash., the writer found some tall-growing blueberries in the woods a 
little way from the narrow road near Markham. The plants here were rather few 
in numbers and scattered, and were rather sparsely set with berries. On examination 
these berries proved to be heavily infested with maggots said by the people in that 
locality to be quite common in blueberries. Some were collected and subsequently 
placed on slightly moist sand in an insectary. These larvae pupated on August 20, 
1918, and adults emerged during the summer of 1919. These have been determined 
by Dr. J. M. Aldrich of the U. S. National Museum as Rhagoletis tabellaria, which 
was originally described by Fitch in 1855 from specimens collected in New York.
