primo dimidio basali sextoque fere toto rufo-testaceis. 
Long. 6 mm. 
9. Head subrectangular, nearly as broad as long, shining, 
and very sparsely punctured ; eyes very small, situated close 
to the base of the mandibles. Thorax and median segment 
shining, the thorax almost smooth, the median segment 
sparsely and finely punctured. Pronotum subrectangular, 
distinctly broader than long ; scutellum fully half as long as 
the median segment, narrowed posteriorly ; median segment 
shorter than the pronotum, slightly broadened posteriorly. 
Sides of the thorax and median segment sparsely clothed 
with long fulvous hairs. Abdomen shining, very closely 
microscopically punctured ; the apical tergite almost pointed. 
Hab. Bembesi, 8S. Rhodesia (G. Arnold), January. 
In the small eyes this resembles atriceps, Turn., but differs 
in the colour of the head and in the much broader median 
segment. The eyes in guadraticeps are much larger, and the 
punctures of the median segment much larger and sparser. 
Elis (Mesa) diversicornis, sp. n. 
&. Niger, albo-pilosus; mandibulis, apice excepto, clypeoque 
flavis; scapo flagelloque articulis duobus basalibus ferrugineis ; 
alis hyalinis, venis nigris. 
Long. 15 mm, 
&. Clypeus broad, truncate at the apex; head coarsely 
and closely punctured, more finely on the vertex than on the 
front, the prominence above the base of the antennz strongly 
raised, transverse, and yellow at the apex; eyes widely 
emarginate. Thorax finely and closely punctured ; the pro- 
notum shoiter than the mesonotum, the anterior margin 
straight; mesopleure more coarsely punctured; median 
segment rugose. Abdomen shallowly and closely punctured ; 
the first segment as long as the second and third combined, 
the petiole less than half as long as the swollen apical portion, 
which has almost parallel sides and is very slightly con- 
stricted at the apex. Seventh tergite with large sparse 
punctures, the apical emargination very small and shallow. 
The abdomen has obscure blue reflexions both above and 
below. ‘Third abscissa of the radius a little longer than the 
second; first recurrent nervure received just beyond the
