PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 103 



basal half. Scutellum sparsely punctured. Base of metanotum 

 almost smooth ; the areola with four si out, curved, transverse 

 keels, the base and apex with a few broken ones, the lateral area? 

 stoutly obliquely, the posterior median transversely striated ; the 

 base of the spii'acular area punctured, the rest closely, obliquely 

 striated. Apex of propleurse Ijelow stoutly striated, above and at 

 the base punctured ; the base in the middle with some stout, clearly 

 separated striae, the lower part smooth and shining. Abdomen very 

 smooth and shining except the second and third segments, which are 

 closely punctured ; the former stoutly striated at the base. 



In the example described, one mandible is black, the other yellow. 



Deniya, gen. nov. 



Temples almost obsolete ; occiput almost transverse. Eyes 

 large, projecting. Apex of clypeus rounded, behind not separated 

 from the face. Antennae dilated beyond the middle. Parapsidal 

 furrows distinct, crenulated. Apex of mesonotum reticulated. 

 Scutellum longer than its width at the base, convex, stoutly keeled 

 to beyond the middle ; the apex with an oblique slope. At the base 

 of the post-scutellum are two triangular depressions, bordered by 

 stout keels. Base of metanotum, deeply obUquely depressed at the 

 base. Areola longer than wide, transverse at the base, the apex 

 angularly turned inwardly ; the sides near the apex angled. Post 

 petiole and the following four segments closely punctured ; gastrocoeli 

 large, deep. Areolet 4-angled ; disco-Cubital nervure not broken 

 by a stump of a nervure ; transverse median nervure received 

 behind tranverse basal. Sheaths of ovipositor broad, projecting. 



This genus comes close to Aluina. The two may be separated 

 thus : — 



Temples wide, occiput widely, deeply incised, apex of clypeus 

 transverse, transver.se basal nervure interstitial ; sides of 

 areola rounded, not angled, parapsidal furrows indistinct, 

 the apex of mesonotum smooth, post-petiole smooth, Aluina. 



Teinples very narrow, occiput transverse, apex of clypeus 

 rounded ; sides of areola not rounded, angled ; parapsidal 

 furrows distinct, apex of mesonotum reticulated, post- 

 petiole punctured, Deniya. 



5. — Deniya pleurcdis, sp. nov. 



Plato A, tig. 10. 



Black ; face, clypeus, mandibles, except at apex, palpi, the inner 



and upper orbits, the lower half of outer broadly, a broad line on the 



pronotum, tegula;, scutellum, the sides of the apical slope of the 



metanotum, a line on the lower edge of the propieuraj, mesopieura?
