Cossonus incivilis Fahr., Ofv. Vet.-Ak. Stockh. Foérh., 1871, p. 285. 
Loc. Seychelles: Mahé. 8. Africa: Caffraria. 
A single specimen, agreeing with one from Natal in the British Museum. This 
insect has an elongate-triangular, deep, rugosely punctate, carinate depression on the 
dise of the prothorax and a broad space on each side of it almost smooth. It was found 
in the high damp forest between Morne Seychellois and Trois Fréres, 1500—2000 feet, 
XII. 1908. 
118. Cossonus suturalis. 
Cossonus suturalis Boh., in Schénh., Gen. Cure., iv. p. 1033. 
Loc. Seychelles: Silhouette. S. Africa. 
One example, also agreeing with Natal specimens in the British Museum (compared 
by Mr Marshall with the type), found in more open secondary jungle-country in 
Silhouette, 3. VIII. 1908. This insect has a rufo-testaceous patch extending down 
the basal half of each elytron, and the deep excavation on the disc of the prothorax 
(which is bordered laterally by a polished space) extending forwards to the subapical 
constriction, and bordered on each side by a double series of confluent foveze. C. varw- 
pennis, Gahan, from Christmas Island, is a smoother, more depressed, allied form. 
RHYNCOLOSOMA, n. gen. 
Rostrum stout, subcylindrical, short, curved, the antennz inserted at the middle, 
the scrobes deep, oblique, descending to beneath the eyes ; eyes lateral, oval, prominent, the 
head constricted behind them, the latter large, globose, and deeply inserted ; antennze 
short, rather stout, the scape reaching to the middle of the eyes, the funiculus 7-jointed, 
joint 1 stout, 2—7 closely articulated, rapidly widened outwards, strongly transverse, 
the club small, ovate, annulate, sparsely pilose, the basal half polished ; prothorax oblongo- 
conic; scutellum small, prominent; elytra oblong, coarsely punctate-striate ; anterior 
coxze large, moderately distant; posterior coxee very widely separated; metasternum 
long, not sulcate; legs short ; tibiee moderately broad, produced into a long curved 
hook at the outer apical angle, and sharply mucronate at the inner apical angle; tarsi 
short, joint 3 transverse, strongly bilobed, pilose beneath, the claws minute; body 
moderately elongate, rather convex, shining, subglabrous, coarsely punctured above 
and beneath, winged. 
Type, Phleophagosoma dubiuwm, Gahan. 
The type of P. dubiwm was from Christmas Island, and the insect proves to be 
common in the Seychelles. It differs in various respects from all the heterogeneous 
forms included by Wollaston under Phiwophagosoma, more especially in the conspicuously 
bilobed third tarsal joint, the small antennal club, which has its basal half polished, 
and the sharply mucronate inner apical angle of the tibiz; and a new generic name 
is therefore required for the species. Rhyncolus (type FR. ater, L.) has a differently 
formed head, &c.
