has found it in abundance, in similar situations, in the same island. Fully developed 
males have the elytral tubercles developed into long conical processes at the commence- 
ment of the apical declivity (the two on each elytron forming with those on the opposite 
wing-case a transverse row), these tubercles in undeveloped specimens of the same 
sex being reduced to small oblong prominences, as in the female. The humeral laminiform 
prominences of the elytra vary in development in a similar way. The rostrum of the 
male is long, carinate, much swollen above beyond the middle, and opaque to near 
the tip; that of the female is shorter, simply curved, carinate in its basal half above, and 
shining throughout. The first ventral segment of the male is transversely excavate in the 
middle, and the second in fully developed examples is tumid in the centre behind. 
The upper surface of the body is somewhat thickly clothed with short stiff erect sete. 
The length varies from 3—4, and the breadth (at shoulders) from 13—22 mm.

Loc. Seychelles: Silhouette. 
Found by Herr A. Brauer in the forests of Silhouette, at an elevation of 400—500 
metres. Mr Scott met with five examples of it in the same island, amongst dead leaves 
in the high jungle at about 1500 feet, and one was bred by him from a larva found 
in damp decaying leaf-bases of a palm on the ground; these are all males. This 
insect differs from feebly tuberculate examples of C. humeroalatus in having the rostrum 
of the male much smoother and without median carina, and tumid above and beneath ; 
the prothorax more rounded at the sides, more closely and less coarsely punctate, 
with the interspaces more or less granulate, and the four transversely-placed tubercles 
less prominent, the two inner ones arising further backward ; the elytra sharply margined 
laterally, and with the laminiform humeral prominences rounded in front ; and the legs 
reddish. The second ventral segment of the male is simple. The upper surface is 
setulose as in C. humeroalatus.

Loc. Seychelles: Mahé, Praslin. Mahé; high forest of Morne Blanc, X. 1908; 
forest above Cascade Estate up to 1700 feet; Mare aux Cochons district, 1000—2000 feet, 
L—Il. 1909. 
The types of this insect were found in Mahé, on damp forest-clad slopes, at an 
elevation of 400—750 metres, and Herr A. Brauer is also stated to have taken it 
beneath leaves on the ground on the high land in Praslin. Mr Scott secured a 
very long series of it, especially in the forest on Cascade Estate in Mahé, but he did 
not meet with it in Praslin. C. foveatus is readily distinguishable by its glabrous 
body, the very coarsely irregularly foveate elytra, and the prominent, posteriorly-directed, 
laminiform tubercle (fig. 15) on the second ventral segment of the male. The rostrum 
of the male is much swollen above at about one-third from the apex, and carinate down
