NATURAL ENEMIES: PARASITIC INSECTS. 149 
Myiophasia senea Wiedemann. 
This tachinid fly (fig. 29) is a widely distributed parasite of the 
larvee 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 Nationa! Museum and the Bureau of Entomology there 
are specimens from the following localities: Chinandega, Nicaragua; 
City of Mexico, Mexico; Sierra Madre, Chihuahua, Mexico; Pecos, 
N. Mex.; Beulah, N. 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, N. H.; 
Douglas, Mich. 
Other recorded localities are: Santa Fe, N. Mex.; Charlotte Har- 
bor, Fla.; New Jersey; Massachusetts; Gypsum, Ohio; Constantine, 
Mich.; Carlinville, Ill.; 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 xnea 
from Balaninus uniformis Lec., at 
St. Louis, Mo., in 1876. In 1886 
Pergande reared it at Washington, 
D.C., from Conotrachelus elegans Say, 
infesting young twigs of hickory. 
Parasites reared by Forbes from 
Sphenophorus parvulus Gyll., and 
a cutworm (Heliophila unipuncta 
Haw.) were identified under one of 
the synonyms of M. ENED (Psyche, Fic. 29.— Myiophasia xnea, 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 ‘7 ~™""? 
a parasite of Heliophila unipuncta, there being no other known instance 
of M. xnea attacking anything but weevil larve. At Gypsum, Ohio, 
Webster found M. xnea as a parasite of Ampeloglypter sesostris Lec. 
(Ent. News, vol. 10, p. 53, pl. 3). In this case a secondary para- 
site (Calyptus tibiator) was reared from M. xnea. More recently 
Pierce (Journ. Econ. Ent., vol. 1, p. 381) has reared MM. xnea from 
tne boll weevil (Anthonomus grandis Boh.) and from Conotrachelus 
elegans Say at Dallas and Victoria, Tex. In the National Museum 
are many specimens of M. xnea reared from Chalcodermus xneus 
Boh. by G. G. Ainslee, Clemson College, 5. C. It had previously 
been reared from a species of Chalcodermus by H. A. Morgan at 
Baton Rouge, La.
