and elytra often darker on the disc, the prothorax sometimes fusco-trivittate and the 
elytra with a very large, common, laterally angulate space mottled with the same colour, 
the outer limits of this space being traceable or indicated by a few streaks in several 
of the light-coloured individuals ; the surface also thickly set with short, curled, adpressed 
sete, which are very conspicuous on the legs and antennze; above and beneath very 
densely, finely punctate. Head and rostrum hollowed and sharply grooved down the 
middle, the inter-ocular space thus appearing raised on each side, the outer margins of 
the former narrowly extended beyond the eyes when the insect is viewed from above. 
Prothorax rounded at the sides, a little narrower at the apex than at the base. Elytra 
convex, with nine regular rows of conspicuous, moderately coarse punctures, the interstices 
broad and almost flat. Intermediate tibize in 3 strongly, in 2 more feebly, unguiculate. 
Length (includ. rostr.) 35—5, breadth 13—2? mm.

Numerous examples, varying in the colour of the vestiture, the dark patch on the 
elytra and the prothoracic vittze sometimes wholly wanting and the scales uniformly 
cinereous. A single specimen only was found on Cosmoledo. The individuals with 
strongly unguiculate middle tibize are assumed to be males.

A large number of species of this genus have been described, mostly from Mauritius 
(Ile de France), Bourbon (Réunion), the Seychelles and adjacent islands, 8. Africa, and 
India. The abundant material obtained by Mr Hugh Scott, Mr Gardiner, and other 
collectors, in the islands under investigation, shows that there are two common variable 
types present—one peculiar to the coasts, the other confined to the mountain forests,— 
and, in addition, a rare, peculiar endemic form in the mountains of Mahé. The former have 
been described under various names, and it is perhaps convenient to give some of them 
specific rank, if localized on particular islands. It may be stated that the genitalia of each 
of them have been examined and no structural differences found, even between such 
dissimilar species as C. adspersus and C. muticus. Several of these local forms are 
represented in the British Museum by specimens received in 1870, as from “ Round 
Island,” which is assumed in their register to be the island of that name a little to the 
north of Mauritius, whereas the Round Island of the Seychelles is probably the correct 
locality for these insects*. 
In addition to the species here enumerated, Fairmaire (Bull. Soc. Ent. Fr. 1891, 
p. xlvi) mentions one other, C. humeralis, Boh., from the Seychelles, probably in error. 
* The very fine Tenebrionid, Dysceladus tuberculatus, C. O. Waterh., from “Round I., Mauritius,” has 
been found in abundance in 1905 on Frigate I. in the Seychelles.
