214 Mr. E. Saunders' Synopsis of 



only a very sliort horny portion at the apex ; 8th pointed at the 

 apex (for genitaha, &c., see PL X., figs. 4 — 4 a). Legs clothed with 

 grey hairs. 



2 . Head and thorax somewhat shining, punctured, the former 

 very large and quadrate on the vertex ; mandibles curved, deeply 

 grooved and bidentate at the extremities, densely fringed with 

 golden hairs on their inner margins ; labrum prominent, shining. 

 Antennae short, subclavate. Abdomen elongate, deeply punctured ; 

 apical margin of each segment with a naiTow band of white 

 adpressed hairs ; scopa beneath yellowish white. Legs clothed 

 with pale hairs. Length, 10 mm. 



Hah. Common in most places, making its nests in

Small, black, elongate. Antennae simple m the ^ ; 2nd segment 

 of the abdomen beneath raised in the centre ; J with the abdo-

^ . Entirely black ; head and thorax largely punctured, 

 sparingly clothed with brownish grey hairs, but more densely on 

 the face below the antennae ; wings shghtly clouded ; metathorax 

 radiately rugose at the base. Abdomen shghtly incurved at the
