[145] HYMENOPTERA 15 1 



times as long as thick, subequal in length, the first slightly the small- 

 est joint ; the club fusiform, stouter than the funicle and j-jointed, the 

 first and second joints subquadrate, the third obtusely conical. 



The thorax, except the metanotum, is almost smooth, or at most with 

 a faint or microscopic reticulate sculpture, the disk of the mesopleura 

 being smooth and highly polished, the parapsidal furrows distinct and 

 complete, the mesothoracic lobes subconvex ; the scutellum is divided 

 by a transverse grooved line near its apex ; the metathorax is sha- 

 greened, without a distinct median carina but with the lateral carina? 

 more or less indicated ; while the spiracles are small and round. 



The abdomen is briefly petiolate, shorter than the thorax and highly 

 polished, impunctate, except the petiole which is shagreened ; the 

 body of the abdomen seen from above is obovate, seen from the side it 

 is more conical, the venter being subcompressed ; the first (body) seg- 

 ment is the longest, fully as long as segments 2 and 3 united, the fol- 

 lowing segments very gradually shortening. 



Male. Length 1.6 to 1.8 mm. Agrees well with the female, ex- 

 cept it is usually more bluish, its antennal and abdominal characters 

 are different and the tibiae are fuscous or brown with both ends yellow 

 (more rarely wholly yellow with the apical half of the femora yellow). 

 The antennae are slightly longer, the flagellum being filiform, not sub- 

 clavate, and clothed with sparse but more erect hairs than in the 

 female, the scape being clavate, thickened towards apex beneath, the 

 funicle joints being fully twice, or more than twice, as long as thick, 

 the first joint being much longer, from 3^2 to 4 times as long as thick, 

 rarely only thrice as long as thick. Abdomen oblong-oval.
