especiall_7 on the thorax and nielian segment ; also in the rerlnc- 

 tion of the second cubital cell. It also differs in these characters 

 from montanus. There is no impressed line behind the posterior 

 ocelli.

2 ■ Nigra, albo-pilosa ; tegulis apice pallide brunneis ; -alis 

 hyalinis, apice late infumatis, venis nigria, stigmate fusco- 

 ferrugineo. 



Long. 11 mm. 



5 . Olypeus produced into a point at the apex, punctured 

 finely and closely, and clothed with rather long whitish pu- 

 bescence which extends on the front a,s far as the emargination 

 of the eyes. Antennae rather slender, not thickened towards the 

 apex, the second joint of the flagellum distinctly longer than the 

 third, but shorter than the first and third comlained. Posterior 

 ocelli nearer to the eyes than to each other, separated from the 

 eyes by a distance considerably less than the diameter of one 

 ocellus ; the eyes nearly twice as far fi'om each other on the 

 clypeus as on the vertex. Front punctured-rugose, the vertex 

 and ocellar space more finely punctured ; pronotum short, steeply 

 sloped anteriorly ; mesonotum a.nd mesopleura coarsely punc- 

 tured, scutellum more finely and sparsely punctured. Median 

 segment closely punctured-rugose, the median sulcus shallow and 

 not extending to the apex, the median cai-ina distinct ; the pos- 

 terior slope rugose, with a shallow median sulcus. Abdomen 

 smooth and shining on the dorsal surface, the segments scarcely 

 depressed at the apex, the apical fascise of white pubescence con- 

 fined to the sides ; the ventral segments sparsely but distinctly 

 punctured. Second abscissa of the radius shorter than the 

 petiole of the well-developed second cubital cell ; second recurrent 

 nervure interstitial with the second transverse cubital nervure, 

 first received by the second cubital cell close to the base ; basal 

 and transverse median nervures interstitial.

A very distinct species, not at all nearly allied to any Ethio- 

 pian form.

The posterior ocelli almost touch the eyes : the puncturation of 

 the whole insect is very delicate, microscopic on both dorsal and 

 ventral segments of the abdomen.
