{in oblique groove from tiie eyes to tlie posterior ocelli ; the 

 liiiid margin of the head slightly raised, snbcarinate. Pro- 

 notnm transverse, the anterior margin raised and shar))ly 

 pointed at the angles ; thorax very coarsely punctured, tlie 

 niesopleurse coarsely rugose. Median segment short ; with a 

 distinct enclosed basal area, which is very finely rugulose, 

 with five strong longitudinal carinas ; the posterior slope 

 rather indistinctly transversely striated; the sides of the 

 segment very finely and closely punctured. Abdomen 

 .■smooth and shining beneath, the three basal dorsal segments 

 coaisely punctured, the three apical segments closely and 

 finely punctured. Recurrent nervure received before the 

 middle of the cubital cell; transverse cubital nervure received 

 just beyond the middle of the radial cell. 



Hah. British East Africa, T-.wm River, 3000 ft., near 

 ]\It. Kenia [G. Orde Broioiu) ; November. 



This is distinct both in colouring and in structural details 

 from E. braueri, Kohl., also in the sculpture of the abdomen. 



Rhopalum tuherculicorne , sp. n. 



<S . Niger ; scapo, tuberculis humeralibus, pedibus anticis, pedibus 

 intermediis tarsis infuscatis, coxisque posticis apice fiavis ; fia- 

 gello fusco subtus ferrugineo ; segmeutis dorsalibus 5-7, ventrali- 

 bus 2-7, tibiis posticis tegulisque pallide ferrugineis ; alis 

 hyalinis, iridescentibus, veuis nigris, cellula radiali infuscata. 



Long. 4 mm. 



(^ . Clypeus uithout a carina, clothed with silver pubes- 

 cence, the apical margin almost transverse. Mandibles 

 blunt at the apex, not bidentate. Second joint of the fla- 

 gellum longer than the third, emarginate at the base beneath 

 and produced into a stout tubercle at the apex beneath. 

 Head smooth and shining ; the eyes separated at the base 

 of the clypeus by a distance slightly exceeding the length of 

 the scape, strongly divergent towards the veitex ; posterior 

 ocelli as far from the eyes as from each other, and also as far 

 from the hind margin of the head as from each other, a short 

 longitudinal sulcus between them. Pronotum short, a minute 

 spine at the anterior angles. Thorax shining, microscopically 

 punctured ; median segment smooth and shining. First 

 abdominal segment scarcely longer than the second, mode- 

 rately swollen at the apex, second segment broadened from 

 the base, third segment broader than long. Hind tibiae 

 broad, with a few small spines on the outer margin. Re- 

 current nervure received just before two-thirds from the base 

 of the cubital cell ; radial cell broadly truncate at the apex.
