C. N. Ainslie and at Tempe, Ariz., by Mr. Wildermuth. Nothing is known 
of its life history. It is also recorded as a parasite of A gromyza parvicornis . 
Pleurotropis rugosithorax Cwfd.*—This species (fig. 14) was reared 
sparingly from a puparium of A gromyza pusilla by both Mr. C. N. Ainslie 
and the junior author at Salt Lake City, Utah. It is an internal parasite, 
having been reared from the immature stages dissected from the puparia 
of the host. Only one parasite issues from each puparium of Agromyza. 
Eucoila hunteri Cwfd.—This species was not previously known. Two 
specimens have been reared from puparia of Agromyza pusilla by Mr. 
A. Rutherford at Dallas, Tex. These issued 16 and 17 days, respectively, 
after the pupation of the host. 
Sympiesis sp. (?)—One specimen of this species was reared by Mr. 
Kelly from mines in alfalfa leaves at Wellington, Kans., in 1912. It was 
also reared from mines in corn leaves at the same locality by the junior 
author in 1909. This is probably a new species and is not confined to 
one host. 
MISCELLANEOUS UNDETERMINED PARASITES 
The following miscellaneous Hymenoptera belonging to the super¬ 
family Chalcidoidea 1 were reared from mines of Agromyza pusilla , the 
species being yet undetermined and their life history unknown. 
Pteromalus sp.—(a) One specimen bearing Webster No. 6639 and 
reared from mines in alfalfa leaves at Salt Lake City, Utah. 
(1 b ) Three specimens bearing Webster No. 7492 and reared at the 
foregoing locality from mined leaves of white clover. 
(c) Two specimens bearing Webster No. 7215 and reared at Tempe, 
Ariz., from mines in alfalfa leaves. 
Cirrospilus sp.—One specimen reared from mines in alfalfa at Tempe, 
Ariz., and bearing Webster No. 7215. 
Diaulinopsis sp.—Two specimens reared from mines in leaves of cowpea 
and bearing Webster No. 6395. 
Entedoninae. —One specimen from mined alfalfa leaves reared at Salt 
Lake City, Utah, and bearing Webster No. 6639. 
BRACONID PARASITES
