longitudinal carina, shallowly triangularly emarginate at the 
apex. Second and third abscisse of the radius subequal, 
second recurrent nervure received a little beyond one-third 
from the base of the third cubital cell.

This may be distinguished from the very similar male of 
E. ruficeps, Sm., by the slenderer, less swollen first tergite 
and by the somewhat deeper emargination of the seventh 
tergite. The form of rujiceps taken at Bulawayo has the 
apical half of the wings infuscate as in the typical Natal 
form. JL. reticulata, Cam., has the first tergite shaped as in 
the present species, but the angles of the pronotum are not 
produced into spines.

Specimens of this from 8. Rhodesia, Bulawayo and Lonely 
Mine, have the head, mesonotum, scutellum, and fore legs 
red, but do not seem to differ otherwise from the typical 
form. They will probably form a subspecies.

2. Clypeus, front, and vertex smooth and shining ; occiput 
closely and finely punctured ; a few scattered punctures 
between the ocelli and the eyes; a short longitudinal sulcus 
from between the antenne reaching halfway to the anterior 
ocellus. Pronotum closely punctured on the anterior margin 
and clothed densely with erect black hairs, shining and 
sparsely punctured on the sides; mesonotum smooth and 
shining, with scattered punctures at the apex and on the sides, 
more closely punctured on the anterior margin, an impressed 
line from the anterior margin not reaching the middle of the 
segment; scutellum and postscutellum very sparsely punc- 
tured; mesopleurz coarsely rugosely punctured and sparsely 
clothed with long black hairs. Median segment closely 
punctured, the lateral lobes broadly smooth at the base. 
First tergite closely punctured and clothed with black hairs, 
a large smooth space in the middle at the base; tergites 2-4
