216 PARASITIC HYMENOPTERA, iii., 



ment of Agriculture (Technical Series, No. 12, Partiv., 1907, p. 37) 

 on a species {M. prima How.) bred from Leucaspis japonica Cock., 

 collected at Tientsin, China, by Mr. C. L. Marlatt. The present 

 species .should be known from the Chinese species, by the latter 

 having the basal nervure distinctly shorter than the median, and 

 the scape shorter, compared with the fourth joint. The amount 

 of the reddish-orange colour varies; it may be owing to discoloura- 

 tion of the specimens when killed by cyanide of potassium; in 

 that case, the colour of the body would be uniformly yellow. In 

 some specimens the eyes are lead-coloured.
