white, terminal joint of tarsi dusky. 
Length .08 inch. 
Bred from Chionobas semidea of the summit of Mt. Washing- 
ton, N. H. (S. H. Scudder.) 
Genus Entedon. 
$ . Body short, shining, quite smooth, sparsely hairy. Head : 
vertex broad, impressed; front abruptly hollowed out. Eyes 
large, ovate, not prominent. Antennae usually seven-jointed, 
filiform, slender, acuminate, longer than half the body: first joint 
long, slender, sublinear ; second, long, cup-shaped ; third-sixth, 
linear subequal; seventh, narrower fusiform, setiferous at tip. 
Thorax ovate, convex ; prothorax very short, not visible from 
above ; mesothoracic scutum short, transverse, lateral lobes indis- 
tinct ; scutellum large, ovate. Propodeum short and small. 
Wings broad, with the pterostigma situated in the outer third 
of the wing, with the subcostal vein ending in a knob, or the 
vein running along the costa to the pterostigma, there being no 
free costal edge as in Encyrtus. Legs strong, simple, subequal, 
ungues and pulvilli small. Abdomen pedicellate, sublinear, 
depressed, shorter and narrower than the thorax (adapted from 
Walker). The male has simple antennae, and in some specimens 
they are ten-jointed; the three terminal ones form an oval club. 
The abdomen is usually ovate, depressed. 
Entedon antiopae n. sp. One $. 
Body short and thick, allied in form to Entedon sodarmus 
Walker. Abdomen sessile, rounded, about three-fourths as long 
as the thorax. Antennae rather short and thick, a little thick- 
ened toward the tip, basal half whitish, beyond brown. Body 
and head brown, shining, smooth ; thorax a little paler than the 
head. Legs pale testaceous ; tarsi paler. Abdomen shining 
mahogany brown, but with no metallic hues. 
Length .08 inch. 
Differs from all the species (four or five) I have seen from 
England, which are bright metallic blue and green, in its mahog- 
any brown colors and pale legs, short, large, round abdomen, and 
clavate antennae, white at base and brown beyond. Described
