NATURAL ENEMIES: PARASITIC INSECTS. 149 
Myiophasia eenea Wiedemann. 
This tachinid fly (fig. 29) is a widely distributed parasite of the 
larva? of several species of weevils, including the plum curculio. 
It is a very variable species, having been described and recorded 
under many names. The species was first described from Monte- 
vidio, Uruguay, South America, but has since been found in Central 
America, Mexico, and all sections of the United States. In the col- 
lections of the National Museum and the Bureau of Entomology there 
are specimens from the following localities: Chinandega, Nicaragua; 
City of Mexico, Mexico; Sierra Madre, Chihuahua, Mexico; Pecos, 
X. Mex. ; Beulah, X. Mex.; Corvallis, Oreg. ; St. Louis, Mo.; Dallas, 
Tex.; Baton Rouge, La.; Inverness, Fla. ; Tifton, Ga. ; Barnesville, 
Ga. ; Clemson College, S. C; Arundel, Md.; White Mountains, X. H.; 
Douglas, Mich. 
Other recorded localities are: Santa Fe, X\ Mex.; Charlotte Har- 
bor, Fla.; Xew Jersey; Massachusetts; Gypsum, Ohio; Constantine, 
Mich.; Carlinville, 111. ; South Dakota. 
It is thus seen that the species extends greatly beyond the range 
of the plum curculio, subsisting on other hosts. Riley, Lugger, and 
Pergande reared Myiophasia senea 
from Balaninus uniformis Lee, at 
St. Louis, Mo., in 1876. In 1886 
Pergande reared it at Washington, 
D. C, from Conotraclielus elegans Say, 
infesting young twigs of hickory. 
Parasites reared by Forbes from 
Sphenophorus parvulus Gyll., and 
a cutworm (HeliopMla unipuncta 
Haw.) were identified under one of 
the synonyms of M. senea (Psyche, FlG . »._ *,***«* ***, a dipterous plum 
VOl. 6, p. 467), but it is probable that curculio parasite: Male and head of female. 
there was an error in recording it as 
a parasite oiHeliopliila unipuncta, there being no other known instance 
of M. senea attacking anything but weevil larvae. At Gypsum, Ohio, 
Webster found M. senea as a parasite of Ampeloglypter scsostris Lee. 
(Ent. Xews, vol. 10, p. 53, pi. 3). In this case a secondary para- 
site (Calyptus tibiator) was reared from M. senea. More recently 
Pierce (Journ. Econ. Ent., vol. 1, p. 381) has reared M. senea from 
the boil weevil (Anihonomus grandis Boh.) ami from Conotmclulus 
elegans Say at Dallas and Victoria, Tex. In the National Museum 
are many specimens of M. senea reared from Chalcodermus seneus 
Boh. by G. G. Ainslee, Clemson College, S. C. It had previously 
been reared from a species of Chalcodermus by II. A. Morgan at 
Baton Rouge, La.
