148 ILLUSTRATIONS OF SOME AFRICAN SPECIES 
with the underside tinged with opaline green. The mandibles 
are large, and furnished with an angular tubercle near the base 
on the outside ; they are black, with the dise opaline green, which 
is also the colour of the upper lip and palpi. The prothorax is 
black, with the disk irregular, being marked with two transverse 
impressions. The scutellum and elytra are black; the latter 
with the shoulders rather rounded (not obliquely truncate), and 
the outer margins beyond the middle coloured yellow, dilated 
towards the apex. The abdomen is golden-coloured above, and 
black beneath, except the two basal segments, which are yellow. 
The prosternum is rather prominent and dilated, sub-truncated, 
(fig. 1 d,) and the mesosternal process is also slightly prominent 
and rounded in front. The underside of the whole of the thorax 
is yellow; the legs are black, the upper side of an opaline green, 
and the under side of the coxee and femora yellow. 
Notwithstanding the great length of the antenne, and especially 
of the last joint of those organs, in the unique specimen hitherto 
known of this species, indicating the male sex, the slight toothing 
of the mandibles, and moderate size of the sternal processes, are 
remarkable. (Fig. 1a, the head, seen in front; 1 4, the same, 
sideways; 1c, the thorax beneath.)

a large black (St. Andrew’s) cross, having two red and two pale
