414 PERCY SLADEN TRUST EXPEDITION 
21. Cycloterinus erosus, n. sp. (Pl. 28, figs. 19, 194, 2.) 
Short, opaque, glabrous; piceous or nigro-piceous, the antenne and tarsi, and 
sometimes the rostrum, femora, and tibiz also, ferruginous. Rostrum in both sexes 
very stout, arcuate, about as long as the prothorax, carinate along the middle and 
sides, seriato-punctate, and opaque to near the tip, in ? a little less curved and more 
shining towards the apex. Eyes very small. Prothorax nearly or quite as broad 
as long, the posterior portion transversely quadrate, slightly widened forwards to the 
obtusely angulate anterior angles, the tubulate anterior portion abruptly separated 
from the rest; coarsely, confluently punctate. Elytra much wider than the prothorax, 
subtriangular, the humeri obliquely truncate in front; seriato-foveolate, the interstices 
3, 5, 7 each with a series of oblong, truncate, or subconical tubercles, which are sometimes 
partly confluent on the disc, those on 7 projecting beyond the margins of the elytra 
as seen from above, 4 and 6 also slightly raised. Beneath coarsely, closely punctate. 
Third tarsal jomt moderately dilated, excavate above. 
Length 14—2 mm. (¢9). 
Loc. Seychelles: Mahé. 
Thirteen specimens, picked up one or two at a time, in the high forests of 
Morne Blane and Pilot, and also found in the Mare aux Cochons district, and on 
the summit of “Montagne Anse Major.” This insect has the general facies of a minute 
Brachycerus, the subconical or truncated tubercles on the elytra, which are sometimes 
partly coalescent on the disc (forming interrupted ridges), projecting laterally beyond 
the margins. The prosternum is unemarginate at the apex, and the anterior coxe 
are moderately separated. 
22. Cycloterinus spheropterus, n. sp. 
Short, very convex, shining; rufo-piceous, the antennz, rostrum, and legs ferruginous, 
set with minute, widely scattered, short, curled setz. Rostrum stout, arcuate, about 
as long as the prothorax, opaque, rugulosely punctate, and carinate to beyond the 
middle, smoother and shining at the tip. Eyes reduced to a few facets. Prothorax 
slightly broader than long, gradually widened to beyond the middle and then abruptly 
narrowed to the short tubulate anterior portion; coarsely, confluently punctate, and 
with a shallow median groove. Elytra much wider than the prothorax, globose, the 
humeri obliquely truncated in front and produced into an obtuse tooth externally ; 
with closely packed rows of very coarse transverse punctures separated by narrow, 
raised, shining interstices, 3 and 5 interruptedly costate, 5 with a conspicuous tubercle 
at the commencement of the apical declivity. Third tarsal joint feebly lobed. 
Length 2mm. (8). 
Loc. Seychelles: Silhouette. 
One specimen from the forest immediately above Mare aux Cochons, over 1000 feet, 
IX. 1908. Ditters from small C. uncristatus by its globose, interruptedly costate elytra, 
the anteriorly widened, rugosely punctate, canaliculate prothorax, and the simply 
arcuate rostrum and non-cristate elytra of the male. The elytral costz are broken up
