2 the ‘Aphis-Feeding Species of Aphelinus. 
By L. O. Howarp. 
toa comparatively recent date, the only Chalcidoid of 
family Aphelininae known to parasitize Aphididae was 
linus mali Hald., described by Haldeman in the Proceed- 
gs of the Boston Society of Natural History, Volume VI, 
Pages 402-403, under the name of Eriophilus mali. It 
™ $ reared by Haldeman from Schisoneura (Eriosoma) lani- 
k, and is referred to under this name by Comstock in his Re- 
‘ ish as eecmnclogist for the United States Department of Ag- 
tic Iture for 1879, and is figured at Plate VI, figure 6, from 
:; reared by the writer from Schizoneura lanigera oc- 
upon apple upon the grounds of the Department of 
at Washington. The species had apparently also 
reared from the same host by Walsh in Illinois and by 
in Missouri. Since then it has been found to be a rather 
parasite of Aphididae, and the following records oc- 
in the writer's Revision of the Aphelininae of North 
_ America (Technical Series No. 1, Division of Entomology, U. 
__ §. Department of Agriculture, 1895) where it was placed in its 
‘proper genus, Aphelinus; by F. M. Webster from Glyphina era- 
at Lafayette, Indiana, September 6 to ro, 1885; by 
the same observer from Aphis brassicae on turnip; by T. A. 
Williams, at Lincoln, Nebr., from Pemphigus fraxinifolii, June 
10, 1890; by the same observer from Aphis monardae at Ash- 
land, Nebraska, May 24th, 1890, and by W. H. Ashmead from 
‘Siphonophora rosae at Jacksonville, Fla., in April, 1881 (de- 
scribed by Doctor Ashmead as Blastothrix rosae, unfortunately 
placing it in the wrong family). Still later and as yet unre- 
corded rearings of this interesting species have been made by 
Zehntner from Aphis sacchari at Pasoroean, Java, and in the 
insectary at Washington by Pergande from Tetraneura colo- 
__ phoidea, November 7, 1897, from Cabin Johns Bridge, Mary- 
_ land. The species seems, therefore, to be not only a very gen- 
“eral parasite of Aphididae, but also seems to be of wide distri- 
” Aphelinus mali was at once set off from the other species
