DESCRIPTIONS OF NEW HYMENOPTERA. 2t7 



Antennse black, distinctly thickened towards the apex ; the flagel- 

 lum thickly covered with a microscopic white down ; the scape with 

 the pubescence longer. Head above the antennse smooth, shining, 

 bearing a microscopic down and having a plumbeous hue ; the clypeus 

 is shagreened, more shining in the middle than on the sides. Pro- and 

 meso-thorax smooth and shining, and covered with a white down which 

 is thicker and more distinct on the pleurae. The depression at the base 

 of the scutellum is finely, transversely striated at the base ; the 

 apical half is longitudinally striated. Scutellum flat, bare, except for a 

 few longish hairs ; the post-soutellum bears about ten, irregular, longi- 

 tudinal keels. The basal third of the median segment is striated all 

 over; in the middle of the remainder are three longitudinal keels; out- 

 side these on the middle part is a shorter keel ; on the sides are two keels 

 with a shorter one in the middle at the base ; on the sides of the apical 

 slope there is only one keel which ends in a short tooth ; the apical 

 slope is more thickly covered with white pubescence than the rest. 

 Pleurae smooth and shining ; the sternum is widely furrowed in the 

 middle. Legs black ; the hinder femora red. Wings clear hyaline ; 

 the stigma is testaceous ; the nervures dark fuscous. Abdomen smooth 

 shining ajad thickly covered with pale pubescence. 



POMPILD^.. 



POMPILUS HBRACLIDES, sp. nov. (Pi. fig. 3.) 



Ferrugineo, abdomine late flavo-balteato ; pedibus rufis ; alis fere 

 flavo-hyalinis, apice fumato. $ 



Length. — 9 mm. 



Habitat. — Deesa. 



Antennse rufo-fulvous, paler, more yellowish on the under-side ; 

 bare. Head wider than the thorax ; transverse behind, bluntly rounded 

 in front. On the head the inner orbits to near the lower ocelli and the 

 sides of the clypeus more broadly and the outer orbits narrowly yellow ; 

 the yellow line on the outer side extending downwards to the mandibles 

 and above across the occiput. Clypeus slightly projecting ; the middle 

 transverse, the sides broadly rounded. Mandibles rufous, black 

 towards the apex. The eyes converge distinctly on the top ; the hinder 

 ocelli are separated from each other by a distinctly greater distance 

 than they are from the eyes. Thorax ferrugineous, covered with a 

 white down ; the apex of the pro-notum is broadly rounded. The 

 median segment has a gradually rounded slope from the base to
