148 THE PLUM CURCULIO. 
stated, its habit of wintering in the cocoon may have caused it to 
have been overlooked. Specimens are in the U.S. National Museum 
from Long Island and Oswego, N. Y., Connecticut, southern Illinois, 
Missouri, and Onaga, Kans. 
(Bracon) Microbracon mellitor Say. 
Aspecimen of (Bracon) Microbracon mellitor (fig. 28) was reared from 
the plum curculio by Prof. F. E. Brooks at French Creek, W. Va., in 
1902 (U.S. Dept. Agr., Div. Ent., Bul. 38, n.s., p.109). In1905 it was 
again reared from the plum curculio at Youngstown, N. Y., North East, 
Pa., Arundel, Md., and 
Fort Valley,Ga. Observa- 
tions by Mr. Fred Johnson 
at Youngstown,N. Y., and 
North East, Pa., indicate 
that this parasite lives ex- 
ternally upon the curculio 
larva, destroying the lat- 
ter before it leaves the 
fruit. The cocoon of the 
parasite is then formed 
within the fallen fruit. 
Bracon dorsata Say. 
Several specimens of this 
insect were reared from 
curculio - infested plums 
from Arundel, Md., Wash- 
ington, D. C., and Lexington, Ky. Other insects were also present, 
and there is a doubt that this species is a parasite of the plum curculio.

Other Hymenopterous Parasites. 
A chalcidid of the genus Eurytoma was reared from Conotrachelus 
nenuphar at French Creek, W. Va., in 1902 (U. S. Dept. Agr., Div. 
Ent., Bul. 38, n. s., p. 109). At North East, Pa., 4 specimens of a 
species of Anisocyrta (Braconide) emerged, July 24, 1906, from the 
soil in a jar in which curculio larve were transforming. An ichneu- 
mon fly, Pimpla (i:piurus) sp., was also reared at North East, Pa., 
from curculio-infested prunes, 3 specimens emerging July 9-23, 1906. 
What is very likely the same species was reared at Youngstown, N. Y., 
in 1905. The parasite destroyed a curculio larva in a small apple 
and formed a cocoon in the dropped fruit. At Vienna, Va., during 
1911, Mr. R. A. Cushman reared the following from the curculio: 
Eurytoma sp., Catalaccus sp., Cerambycobius sp., and Microbracon lixi 
Ashm., which was next in abundance to Triaspis curculionis.
