anticis et intermediis (eaterne nigris) testaccis ; elytris cewruleis, 
purpureo vel violaceo micantibus. Long. 55-65 millim. 3°. 
Mas, capitis basi profuwnde excavato-eroso, erosione ima tota 
nigra ; fronte elevata, in medio profunde sulcata. <Antennis 
acute serratis, articulo quinto triangulari apice nigro. 
Femina, antennis brevioribus, leviter serratis. 
Hab. Willowmore, Cape Colony (Lrauns). 
The head in the male is deeply excavated ; the surrounding parts 
are yellow and elevated, but very differently from either of the 
Hedybii described by me in the ‘Annals and Mag.’ for Jan. 
1900*. The deep notch in the front part of this elevated edge 
of the crater is of itself sufficient to prevent its being confused 
with them. he base of the crater in the male and the base of 
the head in the female are black. ‘The antenne are more acutely 
serrate than in any other species I have seen. ‘They vary in the 
degree to which they are marked with black. Their second joint 
is very short, the third as long as the basal, the fourth and fifth 
triangular, the last in the male always black in its apical half 
and more acutely produced inwards; the following joints are 
longer, acutely serrate, and more or less dark, in the females I 
have seen always dark. 
The thorax is of the same shape asin H. amenus, HT. anceps, Xc., 
but the disk is nearly all suffused with blue-black, two dark points 
project on the base, and it is sometimes indented on each side in 
front. 
The scutellum is black; the elytra are blue and often have a 
beautiful metallic-violet reflection, they are finely coriaceous. 
The legs are yellow but tinged with black, and the hind pair are 
altogether dark, in which respect this insect also differs from any 
of the Hedybii of this group described. 
Three males and two females of this species were sent me by 
Dr. H. Brauns.

Head, thorax, base of the antennez, margins and apex of the
