Plesia transvaalensis, sp. n. 
Black ; the head and thorax densely covered with long white hair? 
mandibles except at apex, a small spot between the antennae, clypeus, 
a line on the base of the pronotnm narrowed in the middle, a broader one 
of equal width on its apex, lines, dilated laterally, on the apices of the basal 
six segments, that on the second slightly, irregularly dilated in the middle, 
a line on the seventh, projecting at the apex along the incision, and with 
a small projection on the inner side in the middle, between the lateral lines, 
which are roundly curved and end in a sharp point at the base, the apex 
being broadly, roundly narrowed ; the yellow lines on the apices of the 
second to fifth ventral segments are broadly dilated laterally, that on the 
sixth is of almost equal width ; there are two small spots on the seventh, 
all bright yellow ; legs bright yellow ; the coxae, trochanters, the four 
anterior femora, with almost the basal half above, the hinder less broadly 
all round, black ; and there is a black line on the outer side of the four 
hind tibiae ; wings clear hyaline, the stigma testaceous ; the nervures 
black ; the second abscissa of the radius is slightly longer than the third ; 
the second transverse cubital is roundly curved posteriorly towards the 
second recurrent nervure, which has the anterior two-thirds and the 
posterior third slightly, obliquely sloped towards the apex of the wing ; 
it is received at a distinctly less distance from the transverse cubital than 
is the first ; the second recurrent curves obliquely outwardly to below the 
middle, where it is roundly curved ; the lower part is sharply, obliquely 
sloped. The transverse median nervure in the hind Swings is broken shortly 
above the middle, the lower and larger part is roundly, obliquely sloped. 
Male. 
Clypeus strongly punctured, the punctures clearly separated, the 
apex with a shallow incision ; front and vertex closely punctured, smooth 
at the sides of the ocelli ; thorax closely, distinctly punctured ; the meta- 
no turn more sparsely at the base, and more finely and closely at the apex ; 
abdomen finely and closely punctured, the last stronger than the others, 
its incision large, about one-half longer than wide.

on the sides of the third, fourth, and fifth dorsal, and narrower continuous 
bands on the whole of the first to fourth ventral, white ; wings bluish- 
violaceous ; the lower part of the apical cubital, the discoidal, anal, and
