from the face, transversely subquadrate, more strongly and remo- 

 tely punctured, its anterior edge deeply concave, labrum fulvous, 

 palpi flavous, antennse pale fulvous, the terminal four joints wan- 

 ting ; thorax quite twice as broad as long, the sides strongly rounded 

 and narrowed towards the apex, the angles acute, the surface finely 

 and rather closely punctured, the interstices minutely granulate ; 

 scutellum broad, impunctate, dark fulvous; elytra not wider at the 

 base than the thorax, but slightly widened towards the middle, the 

 base without dépression, the punctures deep and strong anteriorly, 

 diminishing gradually towards the apex, the interstices flat, shining 

 and impunctate, piceous, this colour gradually shading into pale 

 fulvous at the apex ; underside piceous, legs flavous, the femora 

 without tooth; prosternum impunctate, more or less flavous. 



Hah. Ferguson and Trowbriand Islands. 



Closely allied to R. vittata Blanch. but ot différent coloration, the 

 elytra much more strongly punctured anteriorly and without a 

 dépression. R. coriacea Jac. is another closely allied species but bas 

 the head and thorax strongly and very closely punctured and the 

 elytra uniformly piceous. 



Rhyparida nigripes n. sp. —Black, the basai joints of the 

 antennœ fulvous, thorax extremely finely punctured, convex, elytra 

 with basai dépression, strongly punctate-striate anteriorly, very finely 

 so posteriorly, the interstices scarcely perceptibly punctate, femora 

 unarmed. — Length, 8 mill. 



Head and clypeus nearly impunctate, only a few very fine punc- 

 tures being visible when seen under a strong lens, the clypeus 

 distinctly separated, its anterior margin three-sinuate, labrum 

 piceous, palpi flavous, antennse not extending to the middle of the 

 elytra, black, the lower four or five joints more or less fulvous; 

 thorax about one and a half time broader than long, the posterior 

 margin nearly doubly as wide as the anterior one, the sides strongly 

 rounded and narrowed in front, the angles dentiform, the surface 

 rather strongly convex, extremely finely punctured, the punctures 

 not very closely placed; elytra wider at the base than the thorax 

 with a distinct dépression below the base, deeply punctate-striate, 

 the punctures very fine towards the apex, the interstices with a few 

 extremely fine punctures, underside and legs black, shining. 



Hab. Fergusson Island. 



A comparatively large sized species, which may be known by the 

 impunctate head, the convex and finely punctured thorax and its 

 shape and by the entirely black and shining gênerai colour. 



Rhyparida brevilineata n. sp. ~ Piceous, head, the antennœ 

 and thorax fulvous, the latter finely punctured with two black spots,
