JO Cameron, Hyfnenoptera Orientalia. 



yellow ; the flagellum yellowish -ochraceous beneath ; 

 blackish above ; the flagellum bare ; the scape with long, 

 pale hair. The edge of the pronotum on the top covered 

 with a distinct line of dirty-yellow, depressed pubescence, 

 in front of which is a narrow belt of long, pale hairs. 

 Mesonotum closely and somewhat strongly punctured, 

 opaque; sparsely covered with short, fuscous pubescence; 

 the post-scutellum covered with longer, stiff, pale hair on 

 the top. The "enclosed space" on the base of the median 

 segment shining; distinctly margined behind : and having 

 stout, slightly oblique, widely separated keels ; the median 

 segment with an oblique slope ; rugose, obscurely reticu- 

 lated at the top, and indistinctly keeled down the middle. 

 Mesopleurae thickly covered with long, pale fulvous hair. 

 Legs bright lemon-yellow ; the coxae and trochanters 

 black ; the base of the femora broadly black, tinged with 

 brown ; a brownish mark on the outer and inner side of 

 the hinder tibiae ; the hinder femora have, shortly beyond 

 the middle, a large, oblique, triangular tooth; the hinder 

 tibiae gradually dilated to the apex, which ends on the 

 inner side in a large, triangular tooth. Wings hyaline, 

 slightly infuscated, especially towards the apex. Abdomen 

 black, the apex of the basal three segments with a belt of 

 white, depressed pubescence; the apical three covered 

 entirely with similar pubescence; the first and second seg- 

 ments coarsely punctured ; the third and fourth finely and 

 closely punctured; the last rufous round the apex; the 

 apices of the basal three segments covered with long, 

 white hair, as is also the apical segment. 



The form of the hind legs is not unlike those of N, 

 cornbusta^ with which it otherwise is closely related ; but 

 the shape of the femora serves to separate them ; in 

 N. coinbusta they are roundly curved before the tooth; 

 in N. chrysopa they are perfectly straight, not curved in 

 any way.
