toothed anterior tiliiae of the ■nude will as.-ist in the recognition of it; the in\- 

 jiuuctate head and the distinctly separated clyiieiis, besides other diflferences, separate 

 R. plebeia fi-om R. Imimiea Baly. The female is much shorter, the thorax is more 

 narrowed in front, and the legs are generally more or less marked with fulvous; the 

 tooth of tiie anterior tibiae is also absent. 



Rhyparida curvipes sp. nov. 



Jllack or dark bluisli or purplisli, the antennae dark fulvous, thorax strongly and 

 closely punctured at the sides, elytra very deeply punctate-striate, all the femora 

 with ;i long spine. 



Length 1 line. 



Head strongly and rather closely punctured, bluish, the clypeus not separated from 

 the face, labrum piceous, palpi fulvous, antennae extending beyond the middle of the 

 elytra, fulvous, the terminal joints thickened, longer than broad, thorax twice as liroad 

 as long, the sides slightly rounded and narrowed in front, the surAice \ery closely and 

 strongly punctured at the sides, more remotely at the disc where the punctures are of

 impressed with large, round and deep punctures, black, shining, the sides near the 

 margin with two or three longitudinal costae; femora fusiform, pm-jilish, armed with

This small species has (juite the appearance of a Stelliotes, but possesses all the 

 characters of Rhyparida, although the presternum is much broader than usual ; it 

 might, perhaps, find its place better in a new genus on account of this difference and 

 the shape and structure of the legs. 



Rhyparida prosternalis sp. nov. 



Greenish piceous, basal joints of the antennae and the legs obscure dark fulvous, 

 above metallic blackish green, thorax strongly punctured at the sides, the disc 

 sparingly punctate, elytra deeply punctate-striate, prosternum with the base acutely 

 bidentate. 



S. Posterior femora extending to tlie end of the elytra. 



?. Posterior femora much shorter, general shai)e broader and more robust. 



Length 2h to 31 lines. 



Head finely and rather closely punctured, epistome transverse, sejiarated from 

 the face by a transverse groove, sparingly punctured, mandibles black, palpi fuhous, 

 antennae two-thirds the length of the body, the ba.sal four or five joints fulvous, the 

 rest black, all the joints, with the exception of the second one, very elongate and 

 slender; thorax one half broader than long, the sides evenly but not strongly 

 rounded, scarcely narrowed in front, the surface strongly but not closely punctured at 

 the sides, the middle of the disc very sparingly and finely punctured, all the 

 punctures of uneven size; scutellum subpentagonal ; elytra convex, without basal 

 depression, deeply and closely punctate striate, the punctm'es large and round but 

 diminishing towards the apex ; legs elongate, fulvous, femora unarmed ; jjrosternum 

 widened posteriorly, the base slightly emarginate, the posterior angles produced into
