forwards and low down on the sides of the head, oval, and not 

 longer than the 8th joint of the flagellum. Scape of antenna reach- 

 ing back almost as far as the occiput ; flagellum more clavate than 

 in sennaarensis, 3rd and 4th joints a trifle wider than long, the 2nd 

 and 5th-10th joints as long as wide, the apical joint twice as long as 

 the preceding. Head very little longer than wide, the sides parallel, 

 the posterior angles widely rounded. Pro-mesonotal suture distinct. 

 Dorsum of epinotum narrow, twice as long as wide at the base and 

 rounded at the sides ; declivity oblique, its lateral margins distinct. 

 Node of petiole wider above than below, the dorsal edge considerably 

 rounded, much more so than in sennaarensis, convex in front, flat 

 and vertical behind. First and 2nd abdominal segments sub-equal, 

 wider than long ; the constriction between them feeble.

 placed close to the anterior margin of the head. Thorax rather 

 short ; mesonotum gibbous, surrounded by a deep suture ; dorsum 

 of epinotum narrow at the base ; declivity sometimes excavated so 

 as to lodge the anterior face of the node. Node of petiole high and 

 broad, squamiform and much thinned above. First joint of the tarsi 

 of middle legs not furnished with stiff hairs or bristles on the upper 

 surface. 



5 . Similar to the £ , excepting the usual sexual differences, but 

 considerably larger.
