Rhyparida atra >p. nov. 



Black, basal joints of the antennae fulvous; thorax finely and remotely pnnc- 

 tured at the sides, the disc nearly impunot ate, elytra with hasal depression, strongly 

 punctate-striate. 



Length 1 to Ij line. 



Head finely and remotely punctured at the vertex, the clypeus not separated, 

 without any traces of sutures, a little inoie strongly punctured than the head, 

 antennae extending to the middle of tiie elytra, tlie lower five or six joints fulvous, 

 the others black (sometimes entirely fulvous), third and fourth joints slender, equal ; 

 thorax twice as broad as long, the anterior portion of the sides rather strongly 

 deflexed, the lateral margin very slightly rounded except near the base, the angles 

 obtuse, the surface very finely and sparingly punctured on the disc, the sides scarcely 

 more closely but more strongly punctured ; seutellum broad ; elytra convex, with 

 a rather deep basal depression, the shoulders ]irominent, the surface very shining, 

 black, very strongly puuctate-striate, the punctures slightly finer towards the apex ; 

 legs pitchy or black, the coxae more or less fulvous, prostemum finely rugose. 



Hab. Humboldt Bay and Andai (New^ Guinea). 



The deep black and shining colour and the sparingly jiunctured thorax, the disc 

 of which is nearly impunctate, will help to distinguish this species. The elvtra in 

 some specimens have a slight bluish gloss. 



Rhyparida plebeia sp. nov.

 antennae fulvous, thorax very finely and evenly punctured, elytra with a deep basal 

 depression, distinctly punctate-striate anteriorly, the punctures nearly obsolete 

 towards the apex, the interstices flat, impunctate. 



<S . Thorax transverse, the sides strongly rounded, the anterior tibiae with a 

 n)inute tooth at the middle. 



?. Shorter, the thorax less transverse, the base of the femora and the apex of 

 the tibiae and the tarsi more or less fulvous. 



Length H to 2 lines. 



c?. Head opaque, impimctate, with a short central groove, the clypeus separated 

 from the face by a deep transverse groove, about as broad as long, distinctly but 

 remotely punctui'ed, labrum fulvous, palpi slender, jiale fulvous, antennae extending 

 to two-thirds the length of the elytra, the lower six joints fulvous, the others black, 

 the base of each joint more or less fulvous ; thorax more than twice as broad as long,

 and obsolete, the posterior ones dentate, the surface finely and not very closely 

 punctured, the disc a little less closely than the sides ; seutellum not longer than 

 broad; elytra with the basal portion raised, and bounded below liy a deep transverse 

 depression, the apex rather pointed, the punctures regularly placed, stronger within 

 the depression than towards the apex; the anterior tibiae longitudinally sulcate, 

 robust and slightly widened anteriorly vrith a small tooth at the middle of the outer 

 margin ; prosternum widened at the base, imi)unctate.
