;576COLEOPTERA.BYC. 0. WATERHOUSE.Dr. Coppinger obtained at Eagle Island, in the Amirante group,some Curculionidao belonging to the genus Cratopus, The speciesof this genus are found in the island of Johanna, in Bourbon, Mauritius,and Rodriguez. Species have also been described from Indiaand the Cape of Good Hope, which appear to belong to the genus.I have not yet seen any species from Madagascar.As the species from Eagle Island appears to be undescribed, Ipropose to call it Cratopus adsjjersus.Cratopus adspersus.Oblongo-ovatus, nigro-piceus, pube brevissima grisea vestitus, guttulisminutis cuprascentibus irregularibus adspersus ; thoraceantice fortiter, postice paulo angustato, lateribus rotundatisBcutello pube pallida dense vestito ; elytris ad apiccra modiceacuminatis, punctato-striatis, interstitiis fere planis ; femoribusanticis subtus ante apicem dente minuto instructis.Long. 41 lin., lat. 2 lin.Head finely granulose, with a very slight fovea between the eyes.The eyes not very prominent, nearly round, only very slightly oval.Antennte pitchy, not very long, moderately stout ; the first joint ofthe funiculus about three times as long as broad ; the second jointtwice as long as broad ; the following joints only a trifle longer thanbroad. Thorax convex, finely granulose, much narrowed in front,distinctly narrowed at the base, the sides much rounded ; thepubescence very fine and sparse, but closer at the posterior angles,where it forms a pale spot. Scutellum oblong, pale sandy white.Elytra distinctly broader than the thorax, rather ample, gradually(but not much) widened posteriorly for two thirds their length, notquite four times as long as the thorax, obliquely acuminate at tlieapex ; the apical margins finely serrate. Tlie strife are very distinct,the intervals flat and finely granulose ; the pubescence is fine (notsufiicient to cover entirely the under colour of the surface), but thereis an admixture of less fine slightly coppery pubescence, which givesthe elytra a speckled appearance.JIab. Eagle Island, Amirante Islands.This species resembles C. alhoscuteUatus, Bohem., in general form,but is a much shorter insect, and has the thorax more narrowed atthe base, &c.The only other Coleopterous Insects found in Eagle Island wereDermestes felinus, Eabr., and Opatrum micans, Germar, both commonand widely distributed species.
