and striated. Head about one-third wider, across the eyes, than it is 

 long. Clypeus raised and carinate in the middle. Frontal carinae 

 distinct but very short. Antennae long and filiform, reaching back as 

 far as apical margin of 3rd abdominal segment, scape very short, 

 barely twice as long as the 1st joint of fiagellum ; 2nd joint three and 

 a half times as long as the scape. Eyes not very large, occupying 

 but little more than the anterior half of the sides of the head ; ocelli 

 small, situated on a slightly raised area. Pro-mesonotal suture dis- 

 tinct ; the gibbous scutellum is separated from the mesonotum by a 

 crenate impression. Pronotum exposed, seen from above only two- 

 thirds as long as scutellum ; dorsum of epinotum as long as the 

 scutellum, the declivity oblique and not abrupt. Node of petiole 

 similar to that of the 5 , but smaller and more convex posteriorly ; 

 ventral lamella not produced. The abdomen widens towards the 

 apex; 1st segment not so wide as the 2nd and 3rd, the latter almost 

 twice as wide as long ; constriction between the 1st and 2nd feeble. 

 Apical segment shining and nearly impunctate ; pygidium ending in 

 a short spine. Legs thin and slender ; tarsi of middle and hind legs

 £ . 105 mm. Black ; antennae, tibiae, and tarsi piceous brown, 

 mandibles ferruginous brown. Shining, especially the abdomen and 

 pronotum. Clypeus and sides of pronotum very finely rugulose, 

 pleurae finely striate, all the rest of the body finely and evenly 

 punctured. The punctures are very dense on the head and epinotum. 

 Mandibles shining, with irregular and coarse punctures and a shallow, 

 lateral and transverse fovea near the base. A fine grey pubescence 

 on the whole body, inconspicuous and rather irregular ; pilosity 

 absent. Head very similar to that of E. sennaarensis, Mayr, but 

 the frontal carinae are more divergent behind, and reach to the level 

 of the posterior margin of the eyes. The latter are relatively smaller 

 and more convex. The clypeus is obtusely carinate in the middle, 

 smooth and shining. Mandibles with 12-14 alternating large and 

 small teeth. Antennae long, reaching back as far as base of 1st 

 abdominal segment ; fiagellum very slightly incrassate towards the
