CHAMPION—COLEOPTERA ; CURCULIONIDA 445 
The insect selected as the type of this genus is not unlike Cryptorrhynchus lapathi, 
but differs from it in the strongly depressed mesosternum (the V-shaped mesosternal process 
being entirely absent, and the rostral canal closed by the metasternum), the relatively long 
second ventral segment, &c. The smaller second species referred to Rhetogenes has similar 
sternal and abdominal characters. 
62. hetogenes sexcristatus, n. sp. (Pl. 24, figs. 35, 35a, 3g.) 
Rather broad, robust, black or piceous, the antennee, rostrum, and tarsi sometimes 
rufescent ; variegated with a dense clothing of pale brown, brownish-black, and whitish 
imbricate scales, the dark scales on the prothorax condensed into a triangular patch on the 
basal half of the disc, and the whitish scales on the elytra clustered into various curved 
or sinuate transverse streaks on the apical declivity, the prothorax and elytra also with 
various fascicles of stout, erect, setiform, black and brown scales-—the prothorax with four 
in a transverse row across the middle (the inner two black) and two at the apex, and the 
elytra with several along each alternate interstice, the fascicles becoming larger towards 
the base and smaller towards the apex, the legs annulate and setose. Head transversely 
strigose beneath ; eyes large, coarsely facetted ; rostrum closely punctate, the apical 
portion a little smoother in ?, the antennz inserted at a little beyond the middle. 
Prothorax transversely subquadrate, constricted and abruptly narrowed anteriorly, 
quadrinodose across the middle, the sides parallel in their basal half; densely punctate. 
Elytra broad, oblong-subquadrate, broadly produced at the apex; punctate-striate, the 
interstices broad, densely, finely punctate, 3, 5, and 7 with scattered setigerous promi- 
nences. Beneath dull, coarsely, closely punctate; metasternum short, flattened, not 
suleate ; first ventral segment unimpressed in both sexes. Femora dentate beneath. 
Length 43—51, breadth 21,—22 mm. (79). 
Loc. Seychelles: Silhouette, Long Island. 
Three specimens from the Mare aux Cochons, Silhouette, 1X. 1908, and one from 
Long Island (a small islet close to Mahé), VII. 1908, scarcely varying inter se. 
63. Rhetogenes spurcus, n. sp. 
?. Oblong, nigro-piceous, the antennze and the tips of the tarsi ferruginous ; 
variegated with a dense clothing of brown and blackish scales, the brown scales condensed 
into an interrupted median line on the prothorax, a patch on the scutellum, and various 
faint spots along the alternate elytral interstices, the upper surface and legs also set with 
numerous, intermixed, erect, stout, blunt, setiform scales. Rostrum about as long as the 
prothorax, densely punctate, the apical half smoother and shining, the antennze inserted 
at the middle. Head densely punctured above, strigose beneath ; eyes rather small, finely 
facetted. Prothorax a little broader than long, abruptly narrowed from about the middle, 
densely punctate, without definite prominences. Elytra much wider than the prothorax, 
subparallel in their basal half; finely punctate-striate, the strize sinuate on the disc, the 
interstices broad, densely punctate, the alternate ones here and there faintly nodulose. 
Beneath densely punctate. Femora without definite tooth. 
Length 34, breadth 14 mm.
