quinque aureis. Elytris unicostatis, ad apicem attenuatis, 
singulatim apice rotundatis. 
am. Thorace minuto, subrotundato, remote asperato ; elytris 
amplis, parallelis, bicostatis. 
Long. 11-12 lin., in. 
Green, with the usual subrugose texture of Xystrocera. 
Thorax globose, with smooth shining spots. Underside 
rufous. Mandibles, antenne (first article excepted, which is 
rufous), and legs black, except the thighs, which are reddish. 
Not very rare. 
This genus belongs to the original Indo-African element. 
The species are confined to Africa and the Indo-Malayan dis- 
trict, with a few wanderers over the borders into the nearest 
parts of Australia.

Of a very brilliant blue and bluish green at the top of the 
head and base of the elytra. Head with a very fine black 
groove in the middle, covered with asperities. Palpi (whitish 
at the truncature), mandibles, eyes, and antenne black, the 
latter bearing a great many rough small tubercles, making 
the surface like a file. Thorax a little broader than long, 
rounded on the sides, with the anterior margin straight and 
the posterior bisinuated, broadly channelled on each side, 
smooth, glabrous, and of a fine brilliant blue above, greenish 
on the lower sides. Scutellum triangular, elongated, margined, 
smooth, violet or brown with a violet tinge. Elytra a little 
broader than the thorax, rounded and smooth on the top of the 
Shoulder, almost parallel, only a little wider towards the ex- 
tremity, which is rounded. Their surface has the rough 
punctate wrinkling which is characteristic of the genus. Legs 
and body below deep black; sides of the metasternum clothed 
with a white pubescence, 
Apparently rare, only one or two specimens having been 
received out of many envois. In my collection.
