Qj., 15-17"3 mm. Colour in general like that of sexpunctatus, but 

 the femora are entirely reddish yellow and of a brighter yellow 

 than in that race; the petiole in also reddish yellow, and the spots 

 on the abdomen are brighter and larger, but nevertheless diffusely 

 defined. The spots on the 1st segment are confined for their greater 

 part to the vertical anterior face of the segment and are more or 

 less confluent at their base. The pilosity of the abdomen is reddish 

 yellow and more abundant all over. Head entirely dull, mandibles 

 shining, (subopaque in sexpunctatus). The head is a little more 

 convex-sided than in that race and the clypeus is more sharply 

 carinate. The scape is shorter than in sexpunctatus, extending beyond 

 the hind margin by only one-sixth of its length. The subvertical 

 declivity of the epinotum is much longer, being as long as the 

 dorsum ; the latter is fairly straight and almost horizontal except at 

 its rounded junction with the declivity. Scale of petiole cuneiform, 

 much thinner than in sexpunctatus, very little more convex in front 

 than behind, much higher than wide above. A very fine, yellowish 

 and adjacent pubescence on the thorax, and some fine exserted 

 pilose hairs on the cheeks in front of the eyes. Otherwise like 

 that race. 



^ media, 12*5 mm. Head, thorax, petiole, flagellum and legs red- 

 dish ochreous (reddish raw sienna), the head somewhat darker at 

 the sides, the scapes brownish and more or less ochreous at the base 

 and apex, abdomen brownish or blackish brown, the ochreous spots 

 much larger than in the Qj., diffusely margined, widest anteriorly and 

 so arranged as to leave only a more or less triangular dark area in 

 the middle of each segment; all the segments with the apical margins 

 widely flavous and translucent. The head is less narrowed towards 

 the base and the sides are more convex than in sexpunctatus, the
