150 THE PLUM CURCULIO. 
So far as known M. senea was first obtained as a parasite of the 
plum curculio by Mr. A. A. Girault, who reared a single specimen 
from curculio-infested peaches collected at Arundel, Md., June 29, 
1905. In 1908 another specimen was reared from the plum curculio 
in cherries by R. W. Braucher at Douglas, Mich. At Barnesville, 
Ga., 13 specimens were reared from 1,115 curculio larvae from peaches 
collected on August 5, 1910. The larvae entered the soil August 6 
to 13, and the parasites emerged from August 29 to September 5. 
This species must be considered as only an occasional parasite of the 
plum curculio, the highest known percentage of parasitism being 
1.16 in the case of the lot reared at Barnesville, Ga. A few speci- 
mens of this fly were reared from curculio larvae by R. A. Cushman 
during 1911, at Vienna, Va. 
Cholomyia inaequipes Bigot. 1 
Like the preceding species, Cholomyia inaequipes (fig. 30) is a very 
widely distributed parasite of weevil larvae. It was first described 
by Fabricius from South America in 1805 as Musca longipes, and 
later by Bigot from Mexico under the name of C. inaequipes. Speci- 
mens are in the National Museum and in the Bureau of Entomology 
collections from the following localities: Frontera, Tabasco, Mexico; 
Dallas, Tex.; Lawrence, Kans. ; St. Louis, Mo.; SUoam Springs, Ark.; 
Mound, La.; Fort Valley, Ga.; Barnesville, Ga.; Peaks of Otter, Va.; 
Arlington, Va.; Arundel, Md.; Lexington, Ky. ; West Virginia; 
North East, Pa. 
This insect was first reared by Riley at St. Louis, Mo., under cir- 
cumstances indicating that it was a parasite of the plum curculio. 
In 1897 it was reared at Mound, La., from Conotrachelus juglandis 
Lee. Metadexia basalis Giglio-Tos, which Mr. D. W. Coquillett regards 
as probably a synonym of C. inaequipes, has been reared from Cono- 
trachelus juglandis in West Virginia. Pierce has reared C. inaequipes 
from Conotrachelus elegans Boh., at Dallas, Tex. At Siloam Springs, 
Ark., it has been reared from Conotrachelus affinis Boh. 
The Bureau of Entomology has records of the rearing of this species 
from the plum curculio as follows: 
Arundel, Md., July 13, 1905, 1 specimen (plum). 
Arlington, Va., August 14, 1905, 1 specimen (peach) 
Fort Valley, Ga., October 1, 1905, 1 specimen (Crataegus). 
North East, Pa., July, 1906, several specimens. 
Siloam Springs, Ark., July to August, 1908, 4 specimens (peach). 
Barnesville, Ga., June 20 to September 15, 1910, 81 specimens (peach). 
1 Concerning the synonymy of this species, Mr. D. W. Coquillett has stated that longipes as a specific 
name for this dexidid is preoccupied by Musca longipes Fab. (1794), an entirely different insect from the 
present one, also described by Fabricius under the same name in 1805. The species, therefore, had no 
distinctive name in 1805, and must take the name given it by Bigot in 1884. The synonyms of Cholomyia 
insequipes Bigot (1884) are Musca longipes Fab. (1805) (not 1794), and Thelairodes basalis Giglio-Tos (1893).
