trochanters brown, pale at each end of the articulations ; femora 
brown, pale at tip, or with the rest of the legs, dull honey yellow,

It belongs to that section of the genus in which the head is 
rather short and broad, and the antennae rather long ; the subcos- 
tal vein ends in a knob, and encloses a nearly equilateral triangle, 
and the disk of the propodeum is rather long, regularly convex not 
sinuate, the sides being well curved. Bred from Pieris rapae and 
described from numerous specimens received from England, 
Canada, and numbers bred by myself and others hi the New Eng- 
land States.

(1874). 
One $ closely allied to E. Sweden of Europe (Walker’s 
type). Ocelli jilaced in a narrow triangle. Eyes large and 
near together. Head and body beneath testaceous; a row of 
minute pits along the orbits in front, rather remote from the eyes. 
Mouth parts concolorous with the head. Antennae with the sec- 
ond joint flattened, clavate ; the three basal joints darker than 
the head; joints four to seven brown; eight and nine yellowish ; 
club (joints ten and eleven) blackish; the eight terminal joints 
hairy. Prothorax concolorous with head, rest of thorax and pro- 
podeum bluish green (not very dark) with metallic reflections, 
surface smooth and shining, with small not dense punctures, sides 
of thorax below insertion of wings and legs dark testaceous. 
Tegulae dull testaceous. Wings smoky, paler toward the outer 
edge, with abroad, curved conspicuous white band extending from 
the pterostigma (where it is dilated) across to the inner edge of 
the wing, pterostigma sending a slight spur off toward the centre 
of the wing, enclosing a narrow V-shaped space. Abdomen reg- 
ularly triangular, tip acute, a little longer than broad, being 
pretty short, dark brown, shining, sending off dull metallic hues ; 
under side of a paler bronze color. 
Length .09 inch.
