are placed immediately over the clypeus, which is roundly convex and 

 is rounded at the apex ; the apex itself being depressed. Mandibles 

 lougish, curved, unidentate. Ocelli large, placed in a triangle. Pro- 

 thorax reaching to the tegulse. Scutellum flat, a striated depression at 

 its base ; its sides keeled. Post-scutellum striated. Median segment 

 large, striated ; the sides toothed. Legs short, not elongated as in the 

 Pompilidce ; the middle tibiae with two spurs ; they are not spined ; 

 the tarsi spined at the apices of the joints ; the fore-tarsi are longer than 

 the others and incised at the base. Abdomen broad at the base ; the 

 last segment keeled down the sides and covered with a soft, depressed 

 pubescence. 



The second joint of the antennae is larger than usual ; the middle 

 coxae are widely separated ; the sternum in front of them is raised ; the 

 raised part has a broad, raised, rounded border on the outer-side; 

 the hinder coxae are large and are closed togethei- ; the second abdominal 

 segment is large, and below is separated from the first by a deep de- 

 pression ; the basal ventral segment has the sides keeled ; the middle is 

 stoutly keeled, and from the middle keel others branch off to the apex. 



The fact of this genus having the pro-notum largely developed 

 behind and reaching to the tegulse separates it from the Sphegidce. 

 In the latter respect it agrees with the Pompilidce, from which it differs 

 in some important points : — in the second cubital cellule, receiving only 

 one of the recurrent nervures ; whereas in the Pompilidce^ when there 

 are two cubital cellules, both the recurrent nervures are received in the 

 second ; the antennae are shorter, thicker towards the apex and not 

 curled at the apex ; the scutellum is flatter and keeled ; the median 

 segment is striated ; the legs are shorter, the hinder pair not being 

 lengthened, and there is a distinct pygidium, bordered laterally and 

 covered with pubescence, and the middle coxse are not continuous, but 

 widely separated — feature not found with any known Pompilid. The 

 form of the median segment — in its being longitudinally striated and 

 toothed laterally — reminds one of Dolichurus^ but that is a typical 

 sphegid.
