Longer and narrower than R. fronlalis ; the thorax more finely 

 punctured.

 Late oblongo-ovata, convexa, piceo-fnlva, nitida ; antennis 

 flavis, mandibulis piceis ; thorace elytrorum latitudini fere 

 seqnali, disco magis tenuiter, ad latera subfortiter punctato ; 

 elytris infra basin leviter excavatis ; striis integris, ante 

 medium obsolete sulcatis, sat profunde impressis, punctis 

 pone medium minus distitictis; interspatiis remote tenuissime 

 punctatis, antice obsolete convexiusculis, pone medium planis ; 

 femoribus muticis.

Hab. New Guinea (Dorey). 



Head distinctly punctured; front impressed with a short longi- 

 tudinal groove ; epistome forming a single piece with the front, 

 all the sutures being entirely wanting, its anterior border very 

 slightly concave-emarginate, the angles of the notch not produced, 

 very obtuse ; antennae two-thirds the length of the body, very 

 indistinctly thickened towards the apex ; jaws black. Thorax 

 as broad as the elytra ; sides nearly straight and parallel at the 

 base, obliquely rounded and converging from behind the middle 

 to the apex; the anterior angles rounded, obsolete, the hinder 

 rectangular; surface closely punctured on the sides, less closely on 

 the disk. Scutellum as broad at the base as long, subtrigonate, 

 sides rounded. Elytra subparallel, broadly but very slightly ex- 

 cavated below the basilar space ; striae distinctly and somewhat 

 deeply punctured in front, interspaces obsoletely convex ; finely 

 punctured behind the middle, interspaces plane. 



The plane distinctly-punctured front, and the total absence of 

 sutural lines between it and the epistome, will at once distinguish 

 this species from its allies.

 spatiis pauUo convexis ; femoribus simplicibus.
