DESCRIPTIONS OF NEW HYMENOPTERA, 275 



Length.— 8 — 9 mm. 



Habitat. — Deesa. 



Anteunse black ; the apex of the scape aud the base of the flagellum 

 rufous ; the under-side of the scape and the base of the flagellum 

 bearing a few long white hairs. Head black, shining, bare ; the 

 antennal tubercles and the apex of the clypeus rufous; the apex of the 

 clypeus transverse ; its sides straight ; it is sparsely punctured. On 

 the base of the mandibles are some long, pale, fulvous hairs ; the apex 

 blackish. Thorax black, smooth and shining ; the base of the pro- 

 notum and the pleura are sparsely covered with long, soft, white hair ; 

 the base of the pro-notum is sparsely punctured ; the apex is piceous ; 

 on the sides of the scutellum are four punctures ; the base of the 

 median segment is indistinctly furrowed. The base of the pro-pleurse 

 bears some minute punctures ; its apex and the meso-pleurae are 

 strongly, but not very closely, punctured ; the upper part of the 

 meta-pleuras closely, obliquely and minutely striated. Wings hyaline ; 

 the stigma black ; the nervures testaceous. Legs black ; thickly 

 covered with longish white hairs ; the tibise and tarsi dark rufo-testa- 

 ceous ; the tibia? darker behind. Abdomen ferruginous, smooth and 

 shining ; the basal segment except at the apex, the second segment at 

 the base laterally, and the base of the third laterally to a less extent, 

 black ; in front of the black marks is an irregular, oblique, white mark. 



Mez'ra has not been hitherto recorded from the Oriental Zoological 

 Region. It is allied to Tiphia and Scolia^ and is easily known by the 

 peculiar neuration of the fore-wings ; the second cubital cellule is largely 

 appendiculated ; the first transverse cubital nervure is oblique, and bears 

 the minute cubital cellule on its lower end near to the cubitus!; the 

 radial cellule is open in the 9, closed in the $i the third cubital 

 cellule is very large, being as long as the radial. 



NuKSEA, gen. nov. 



Wings with two cubital cellules • the first recurrent nervure received 

 in the first, the second in the second cellule ; the former at a con- 

 siderable distance from the transverse cubital nervure, the second 

 close to it. Antennae becoming gradually thicker towards the apex ; the 

 last joint large, twice the length of the preceding. Head distinctly 

 narrowed behind the eyes ; the occiput is sharply keeled. The antennae 



t In the figure this little cellule is not shown.
