CHAMPION—COLEOPTERA ; CURCULIONIDA 407 
amongst the Hylobiina, near Styphloderes. All these insects occur on the sea-shore, and 
appear to be easily introduced in drift-wood, &c. Gononotus has been recorded from 
Florida and Cuba, and Dryotribus from Florida, the Antilles, the Hawaiian Is., Adéle 
Island (N.W. Australia), and Nyew-tew Island, China. Gonotrachelus, therefore, may 
have been introduced into the Seychelles, but from whence it is impossible to say at 
present. 
13. Gonotrachelus quinquecarinatus, n. sp. (PI. 22, figs. 11, 11a, 6.) 
Oblong-ovate, opaque, piceous, the antennze ferruginous. Head and rostrum rugosely 
punctate; antennz short, the joints of the funiculus comparatively stout, 2—5 transverse. 
Prothorax subquadrate, about as broad as long, abruptly constricted anteriorly ; very 
coarsely, confluently punctate, and sharply 5-carinate, the two outer carinze on each side 
sinuous, becoming divergent anteriorly, the outer one marginal and forming a blunt tooth 
at its point of termination. Elytra much wider than the prothorax, oval, truncate at the 
‘base, the humeri obtuse; coarsely punctate-striate, the interstices narrow and more 
or less costate, 3, 5, and 7 sharply raised. Beneath coarsely, closely punctate, the 
imterspaces alutaceous. 
Length 2—2}4 mm. 
Loc. Seychelles: Long Island, near Mahé, VII. 1908. 
Two specimens, probably male and female. 
Group Anchonina. 
Anchonina Champion, Biol. Centr.-Am., Coleopt., iv. 4, p. 66 (1902). 
Faust (Deutsche ent. Zeit. 1892, p. 19) referred numerous American genera to 
this group and others from the same continent were subsequently added by myself. 
Cycloterinus, Kolbe, has the head, &c., formed exactly as in these American forms— 
Kolbe, in fact, notes its resemblance to Oncorrhinus,—and the genus is much better 
placed in Anchonina than in Hylobiina. The group is represented in the Seychelles 
by two genera. All the species are apterous, and in one, Cycloterinus cecus, the eyes 
are wanting. C’. foveatus is not unlike the American genus Theognete, which has the eyes 
placed on the sides of the rostrum, instead of on the smooth, globose, retractile head. 
Mr Scott notes that he obtained all his material, with the exception of one species 
(ce; carinifer), from the forest-clad mountains, from amongst dead leaves on the 
ground. The largest form, Tanyomus palnucola, was found exclusively on the concave 
inner surfaces of the bases of damp decaying palm-leaves. The larger forms of Cyclo- 
terinus (such as C. foveatus and C. humeroalatus) were also often found in similar 
situations on dead palm-leaves, but some of them may also have been on leaves of 
dicotyledonous trees. The smaller Cycloterinus (e.g. C. wnicristatus) were found on 
leaves of the “Bois Rouge” (Wormia ferruginea) and of the ‘Capucin” (Northea 
Sechellarum), both endemic trees. The one exception mentioned above (C. carinifer) 
was not found on the ground at all, but in decaying outer leaf-bases of a growing 
Lodoicea-palm.
