a deep crease along the middle of the upper side, and it 

 is much lighter in color and Avith more decided metallic 

 reflections than on the rest of the body. The antennte are 

 honey-yellow, Avith 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 coarsel}^ punctured. The scu- 

 tellum of the metathorax is regularly convex, not keeled, in 

 both sexes. The antennas are brown, and the legs brown, 

 becoming pale towards the ends, the ends of the femora 

 (thighs) being pale ; the tibij£ are pale-brown in the middle, 

 much paler at each end, while the tarsi ai"e 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' Fteromalus 

 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 bod}', the antenntu 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 eud 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 Ilj'menoptera, and was long ago described by 

 Linnajus under the name of I'tcromalus imparum, from tlie
