a deep crease along the middle of the upper side, and it 
is much lighter in color and with more decided metallic 
reflections than on the rest of the body. The antennae are 
honey-yellow, with narrow black wings. The legs are pale 
honey-yellow. It is from one-twelfth to one-tenth of an inch 
in length. 
The body of the female, which would be thought at first 
to be an entirely different kind of insect, is much stouter, 
broader, with a broader oval abdomen, ending in a very short 
ovipositor, while the underside of the body near the base has 
a large conical projection. It is much duller green than the 
male, and the body is more coarsely punctured. The scu- 
tellum of the metathorax is regularly convex, not keeled, in 
both sexes. The antennae are brown, and the legs brown, 
becoming pale towards the ends, the ends of the femora 
(thighs) being pale ; the tibiae are pale-brown in the middle, 
much paler at each end, while the tarsi are whitish, though 
the tip of the last joint is dark. It is from a line to a line 
and a third in length. It differs from Harris’ Pteromalus 
vanessce in the little piece known as the scutellum of the 
metathorax being smooth, not keeled, and by its darker legs. 
The larva is a little white maggot about a sixth (-17) of 
an inch in length. The body consists of thirteen segments, 
exclusive of the head, and is cylindrical, tapering rapidly 
towards the head, while the end of the body is acutely 
pointed. The chrysalis is whitish, the limbs being folded 
along the under side of the body, the antennae reaching to 
the end of the wings ; the second pair of legs reaching half¬ 
way between the end of the wings and end of abdomen ; while 
the tips of the third pair of feet reach half-way between the 
second pair of feet and the end of the abdomen. It is from 
a line to a line and a third in length. 
This invaluable ally of the gardener is one of the chalcid 
family of Hymenoptera, and was long ago described by 
Linnaeus under the name of Pteromalus puparum , from the
