P. CAMERON. HYMENOPTERA. 209 



the basai latéral is larger, semicircular, the 2nd is quadrangular, narrowed on the inner side, 

 where it is about one half the size of the outer. The ist abdominal segment is about one quarter 

 longer than it is wide at the apex, the 2 n d almost square, the others wider than long, the 

 apical shorter than the middle ones. Antennal scape yellow, black above, the flagellum black, 

 brownish below. Q. 



Length 13 m. m. ; terebra 3 m. m. 



The terebra is stout and is as long as the hind tarsi. Face a little wider than long, 

 closely strongly punctured ; the clypeus is more weakly punctured on the upper half, smooth 

 on the lower. Parapsidal furrows on basai half of the mesonotum only ; the basai half of the 

 latter punctured, the apical smooth. Scutellum weakly punctured, the keels not very promi- 

 nent. Mesopleurae closely, distinctly, but not very strongly punctured below the tubercles, 

 the latter weakly sparsely punctured. The base of the hind tibiae is marked with black. 



Pimpla crassipes, Brullé, Hymen. IV, 95, 15 from New Guinea, seems to be a species 

 closely related to the above; unfortunately no mention is made of the structure of the meta- 

 notum, except that it is as in X. pedator, in which case it differs in having 3, instead of 2 

 basai areae; following the 3 are „deux espaces aboutissant aux angles de celui-ci, enfin un 

 grand espace polygonal qui s'étend jusqu'à l'extrémité." 



2. Xantlwpimpla xanthocepliala sp. n. 

 Bivak Island, January. 



Rufo-testaceous, the head, scutellum and pleurae pallid yellow, the antennal scape 

 yellow, black above, the flagellum brownish, the apical half blackish; wings hyaline, the apex 

 with a distinct smoky border, the stigma and nervures black, the areolet oblique, shortly 

 appendiculated, receiving the récurrent nervure in the middle. Areola of equal width, two- 

 and a half times wider than long; the latéral areae almost semicircular, but more narrowed 

 in the middle for a semicircle. There are shallow transverse furrows near the apex of the 

 2 n <i to 6* abdominal segments; the segments are not raised. The parapsidal furrows are on 

 basai slope only; the mesonotum is raised between them. Scutellum broadly roundly convex; 

 the sides and, to a less extent, the apex stoutly keeled. The clypeus is not separated from 

 the face; its apex is not quite transverse. The i st abdominal segment is not one fourth longer 

 than wide. Q. 



Length 10 m. m.; terebra 3 m. m. 



The abdominal segments are smooth, not punctured. The face is flat and smooth. The 

 terebra is broad, slightly curved and stoutly built. The transverse médian nervure is interstitial ; 

 the transverse médian nervure in the hind wings is broken above the middle. 



This species differs from typical Xanthopimpla in the abdomen being smooth and 

 impunctate; in the other characters — in the form of the scutellum and metanotum — it agrées 

 with it better than with Theronia. 



Theronia Holwg.
