9 black throughout, head and thorax and the abdomen except at the

 clothed with pale hairs, closely and finely punctate above the antennae, 

 clypeus also punctate and a trifle convex, supraclypeal plate short and 

 wide, mesoscutum closely and finely punctate, scutellum finely punctate

(5 with the whole face below the antennae yellow, the marking- 

 being continued up the side of the face along the eye margin as a broad 

 vitta, often a yellow spot on the scape outwardly and the labrum and 

 prothoracic tubercle yellow, all the tibiae and tarsi likewise yellow, the 

 middle and anterior tibiae however with a black spot behind and the 

 posterior tibiae incompletely banded with black. Face longer than wide, 

 not at all convex, the cheeks between the eyes and mandibles short, 

 scape of antennae hardly dilated, more than twice as long as wide, gently 

 arched beneath, the supraclypeal plate not much longer than wide, head 

 above the antennae hardly shining but not altogether dull, rather 

 coarsely rugulose and fairly closely, irregularly, shallowly and not too 

 finely punctate. Mesoscutum and scutellum dull, probably more so than 

 the head, mesoscutum with the surface finely rugulose and rather regu- 

 larly, closely shallowly and finely punctate, scutellum a little more shin- 

 ing, the punctures of larger diameter and not so regular. Propodeum 

 rugose with a few rather long wrinkles at anterior end. Abdomen not 

 so dull as the thorax, finely rugulose, the ist segment especially smooth. 

 Wings slightly infuscate. Wings of the 7th ventral segment narrow and 

 short, the process of the 8th ventral segment expanded at the flexure, 

 the bifurcations turned upward. 



5 entirely black, only the front of the anterior tibiae and the under 

 side of the flagellum reddish yellow, shining but not highly polished, 

 sculpture of the head distinct, the punctures large but shallow, the punc- 

 tuation of the mesoscutum and scutellum regular, close and fine, the 

 punctures a trifle larger on the scutellum and not so close together, 

 propodeum rugose and much wrinkled anteriorly, abdomen fairly smooth. 

 Wings clear.

$ black, the face marked with yellow on the clypeus anteriorly and 

 (sometimes) on the supraclypeal plate, also two fairly wide yellow vittae 

 along the orbital margin extending beyond the antennae, the mandibles 

 also bear yellow markings, the antennal scape is orange red as is also the 

 under side of the flagellum, there is a complete thin yellow line on the 

 prothorax, the legs also are orange red with the exception of the coxae 

 and sometimes with fuscous markings, and abdominal segments i. 2 and 3 

 (sometimes) are orange red at the base. Head and thorax dull, the 

 abdomen shining, head wider than long, closely and rather coarsely punc- 

 tate above the antennae, supraclypeal plate with the anterior margin 

 about as long as the lateral, the clypeus shallowly punctate bearing pale 

 setae, the antennal scape is somewhat expanded, almost straight in front 

 but well curved behind and arched beneath, mesoscutum and scutellum
