Coleoptera, 111 



One male example of this very distinct species was taken near 

 Mying Fish Cove. The female sex is still unknown. 



60. Rhyncholobus andrewsi, Gahan, sp.n. 



$. Piceus, viridi - sqnamosus (interdum coeruleo - squamosus) ; 

 prothorace quam longiore evidenter latiore, sat dense nigro- 

 granulato ; supra in medio minus dense squamoso ; elytris 

 punctato-striatis, interstitiis convexis, sat dense irregulariterque 

 granulatis ; disco pauUo convexo, lateribus abrupte deflexis ; facie 

 postica f emorum posticorum planata vel leviter concava, sat fortiter 

 transversim rugosa ; tibiis omnibus subtus denticulatis. 



Long. 9-11, lat. 4-5 mm. 



9. Piceo-fuscus (interdum brunneus) ; prothorace supra versus 

 latera luteo-viridi-squamoso ; elytris punctato-sulcatis, interstitiis 

 subcostiformibus, disco sat fortiter convexo, versus latera et apicem 

 luteo-viridi-squamoso. 



Long. 8-10, lat. 4-5 mm. 



Male. — Pitchy-black, covered with bright green or with bluish 

 scales, which are more thinly placed or entirely wanting along the 

 middle of the pronotum. Prothorax distinctly broader than long, 

 its greatest width being in front of the middle, where the sides also 

 are most rounded. Disk of the elytra only slightly convex, and 

 the sides abruptly deflexed, so as to form with the disk a rather 

 acute angle ; the interstices between the punctured striae are slightly 

 •convex, and rather thickly and irregularly granulate. Posterior 

 (or inner) face of the hind tibise flattened, or perhaps slightly 

 •concave, and distinctly wrinkled in a transverse direction. Lower 

 margin of all the tibiae denticulate. 



Female. — Dark brown, varying to reddish brown, in colour. The 

 scales are almost entirely confined to the sides of the pronotum and 

 to the lateral and apical parts of the disk of the elytra, and are, 

 moreover, of a yellowish- or greenish - grey colour. Pronotum 

 relatively shorter than in the male. Elytra strongly enough 

 convex above, punctate-striate, with the interstices raised, convex, 

 and somewhat costiform. Posterior flattened face of hind femora 

 feebly wrinkled towards the margins, but not in the middle. Tibiae 

 very faintly denticulate along the lower margin. 



Although the sexes here described are so remarkably different in 

 many characters, there can be little or no doubt that they belong 

 to the same species. Mr. Andrews collected a fair series of each 

 sex on the same day and at the same place on the island — viz., 

 IS'orth-East Point, December 23, 1897. 



Mr. J. Paust, who has kindly examined some specimens sent 

 to him, points out that while this new genus has a general 

 resemblance to Elytrogonus., Guer., it agrees in the connate claws 

 oi the tarsi with Lacordaire's group Oosomides^ and might be placed 

 near Umbrithes^ Sch., and Dicasticus, Pasc.
