TYRIOTES. 
Rostrum tenue, subrectum ; scrobes submediane, oblique, infra ros- 
trum currentes. Antenne tenues ; scapus brevis ; funiculus nor- 
malis; clava distincta. Oculi ovati, contigui. Prothoraxz sub- 
conicus, basi bisinuatus. lytra cuneiformia, humeris rotundatis. 
Femora infra acute dentata; tbr breviuscule, unguiculate, an- 
ticee curvate, intus angulato-emarginate ; tarsi breves, articulo 
penultimo late subbilobo ; wngwiculs basi fortiter dentati. Propec- 
tus haud canaliculatum ; cove antice contigue, postice distantes. 
Abdomen segmento primo amplissimo. 
This genus may be placed near Sphadasmus, with which, 
however, it has only a partial affinity. Its predominant cha- 
racters are the form of the elytra, the toothed claws, and the 
eyes contiguous along the whole of the inner margin. 
Tyriotes cuneipennis. (Pl. XVIII. fig. 7.) 
T. modice elongatus, niger, squamulis albis pone medium elytrorum 
condensatis fasciam latam formantibus ; corpore infra dense albo- 
squamoso. Long. 4 lin. 
Hab. Cameroons. 
Moderately elongate, black, with small indistinct patches 
of white scales, others condensed behind the middle of the 
elytra, forming a broad band; rostrum nearly straight; an- 
tenne black, but the scape pitchy at the base; funicle with 
the second joint nearly half as long again as the first, the rest

sunk in a broad hollow formed by the elytra and prothorax ; 
elytra striate, with linear not approximate punctures, the apex 
of each rounded and scarcely covering the pygidium ; poste- 
rior femora extending beyond the elytra; inner edge of the 
anterior tibie towards the apex strongly emarginate; body 
beneath and sides of the head and prothorax densely covered 
with white scales.

Ocult magni, rotundati, supra approximati. Scapus antennarum 
oculum attingens ; funiculus 7-articulatus, articulis duobus basali- 
bus elongatis, equalibus, tertio minus elongato, quarto quintoque 
brevibus, sexto septimoque crassis, obconicis; clava elongata,
