Natural Enemies. — We have reared several braconid and ichneu- 
monid parasites of the seed-caterpillar which await authentic determin- 
ation. The following species have been published as parasites of this 
host: the ichneumonid Glypta Iciicozonata Ashm. (Proc. U. S. Nat. 
Mus., Vol. XII., 1889 [1890], p. 449), reared in Missouri by Miss M. 
E. Murtfeldt ; the braconid Phanerotoma (Sigalphus) tibialis Hald. 
(Proc. Acad. Nat. Sci., Phila., Vol. IV., 1849 [1850], p. 203), raised in 
Washington, D. C, by Comstock; and a second braconid, Microdus 
laticinctns Cress. (Can. Ent., Vol. V., 1873, p. 53), recorded from 
Missouri, Iowa, Canada, and elsewhere. In Iowa, Osborn and Gos- 
sard have reared the last in abundance from cocoons of the clover 
seed-caterpillar, and have found that it corresponds exactly with its 
host as regards the number and the duration of the broods. 
Gossard expresses the presumption that the braconid Bracon ver- 
nonice Ashm. (Proc. U. S. Nat. Mus., Vol. XI., 1888 [1889], p. 619) 
is a parasite of E. interstinctana in Iowa, since it is associated with the 
latter species in marked numbers and corresponds closely with it in 
time of appearance. 
Control. — The best remedy for the attack of the seed-caterpillar is 
that proposed by Comstock, namely, to cut and store the hay crop 
early in June (New York, Illinois, Iowa), just as advised for the seed- 
midge, in order to kill the larvae while still in the heads. The hay 
should be handled lightly and stacked or stored as soon as possible. 
Osborn and Gossard have attested the value of this method, and have 
given these further recommendations: (1) cut volunteer clover in early 
June and dispose of the heads speedily; (2) do not allow clover to run 
for more than two years ; (3) sow seed on land remote from old fields ; 
(4) pasture clover in the fall of the first year; (5) plow an old clover 
field under in October or November or in early spring, then harrow and 
roll. These practices operate at the same time against several other 
clover pests.
