neio species of EumolpidcB. 41 



metallicis, reg'iilariter punctato-striatis, striis ad apiceni 

 minus fortiter punctatis. 



Long. 3 lin. 



Hub. — JSTew Hebrides. 



Head smooth, remotely punctured ; clypeus semiovate, 

 its apical border obsolete ; three lower joints of antenna? 

 rufo-fulvous, the rest black ; ja\vs nigro-piceous. Thorax 

 not broader than long; sides regularly rounded, converging 

 at base and apeix, all the angles acute ; disk remotely punc- 

 tured. Elytra much broader than the thorax, oblong, 

 sides parallel, apex subacutely rounded ; above convex, 

 not excavated below the basilar space, the humeral callus 

 moderately prominent ; surface distinctly punctate-striate, 

 the sti'ife less strongly impressed on the hinder disk ; in- 

 terspaces plane, impunctate. 



Rhyparida Hoioiiii. 



Anguste oblongo-ovata, sordide rufa, subnitida, subtus 

 nitida, genubus, tibiis apice, tarsis, pectore abdoraineque 

 piceis ; antennis (basi excepta) nigris ; elytris punctato- 

 striatis, viridi-metallicis. 



Long. 3 lin. 



Hah. — Australia. 



Head minutely granulose ; clypeus not distinctly sepa- 

 rated from the face, its apex rounded, its anterior border 

 edged mth piceous, deeply notched ; surface distinctly but 

 not closely punctured; vertex very minutely punctured, 

 the punctures remote ; upper face impressed with a longi- 

 tudinal sulcation, which extends upwards from the apex 

 of the clypeus; apices of jaws black ; four lower joints of 

 antemiJB rufo-fulvous, the rest black. Thorax twice as 

 broad as long, sides nearly parallel at the base, thence 

 roimded and converging to the apex, all the angles acute ; 

 above moderately convex, minutely granulose, impressed 

 with very fine, scattered punctures, only visible under a 

 lens. Elytra oblong, their sides parallel, their apices 

 regularly rounded ; above convex, faintly excavated below 

 the basilar space, the humeral callus moderately promi- 

 nent ; surface strongly pimctatc-striate, less strongly im- 

 pressed posteriorly ; interspaces plane, faintly convex near 

 the apex. 



The different form of the thorax will at once separate 

 the present from the preceding species.
