the beetles eating leaves or tender twigs, but they sometimes feed on the 
succulent globular leaf galls of cecidomyiid larvae. They will puncture 
and feed on young apples in the cages when fresh haws are not to be had, 
but the writer has found none feeding on apples in the field. 
After feeding for a week or ten days the beetles may be found in copula- 
tion on the branches, and a week or so later, as warm July weather comes, 
they disappear from the trees. Those kept in breeding cages remained 
hidden in fallen curled leaves and hollow twigs on the ground all summer 
and winter without feeding until the next spring. A search for their 
hiding places in the field revealed a score of the beetles inclosed in curled, 
dried leaves on the ground beneath their host trees. 
The life cycle may be summarized as follows: The immature stages 
(egg, larva, and pupa) are completed within the closed blossom in from 
twenty-seven to thirty-five days, and the remainder of the year is passed 
in the adult stage. The adults feed on thorns and fruit for two or three 
weeks after emerging from the blossoms, and then remain quiescent 
among fallen leaves on the ground until the next spring, when they feed 
for about a month on the buds before ovipositing. Soon after oviposition 
the beetles die. In New York the eggs are laid about mid-May and the 
beetles emerge from the blossoms in June. W. D. Pierce, in a letter to 
the writer, says the beetles emerge in late March and early April in Lou- 
isiana. The time of their development in different latitudes is dependent on 
. the opening of the hawthorn blossoms in those latitudes. 
A number of natural enemies of the blossom weevil have been observed. 
Various birds, especially sparrows, pick open_the brown blossoms to eat 
the larvae and the pupae. Pierce (1912:77) found the weevils to be para- 
sitized by Catolaccus hunteri and Sigalphus sp. The writer has bred 
another chaleid, Habrocytus piercei Cwfd., from the larva of the weevil, 
the adult parasites emerging on June 16 and 17. 
quadrigibbus Say, Tachypterus (Apple curculio) 
The four-humped brownish beetles of the species Tachypterus quadri- 
gibbus were found occasionally feeding on the fruit of native hawthorns 
in June. Fruits of Crataegus punctata were put into rearing cages on 
June 25, and from these fruits five adults of this species emerged on 
July 15 and July 18. 
LEPIDOPTERA 
Papilionidae 
turnus Linn., Papilio (Tiger swallowtail) 
The green larvae of Papzlio turnus, with their peculiar eye spots, were 
found feeding on the foliage of native hawthorns from June 20 to August 2. 
The species is not very common,
