is lanceolate instead of being spatuliform, the labial palpi are inserted 

 on the outer face instead of laterally, the ligular part is differently 

 incised, and the last joint of the labial palps is not so broadly swollen 

 outwardly. 



DlPLOEIDA MODESTA, n. Sp. 



Dark chestnut-brown, sub-opaque ; antennae light chestnut ; 

 clypeus sub-parallel laterally for half its length, attenuated diagonally 

 thence to the anterior part which is triangularly incised, the apex of 

 the incision is prolonged into a slightly raised line dividing the 

 anterior part of the clypeus into two shallow hollows, both head and 

 clypeus are roughly and closely punctured, and the canthus of the 

 eyes is very densely hairy ; prothorax convex, one-fourth broader at 

 the base than at the apex, not sinuate laterally and with the basal 

 angles rounded, the base itself is bi-sinuate ; the surface is covered 

 with round, shallow punctures separated from each other by a 

 smooth space equal to their own diameter, and the outer margin has 

 a fringe of moderately long, fulvous hairs ; prothorax cordiform, deeply 

 punctate ; elytra a little broader than the prothorax, slightly sinuate 

 laterally, and somewhat ampliated thence towards the posterior 

 part, they are coriaceous rather than punctate, the suture is tecti- 

 form, and they are costate, with the discoidal costae better defined 

 than the lateral ones ; pygidium sloping, glabrous, faintly punctate 

 except at apex ; abdominal segments with one or more series of 

 punctures bearing each a long, fulvous hair; pectus and legs 

 moderately hairy ; legs strong, tarsi short ; anterior tibiae tri-dentate; 

 upper spur of hind tarsi slightly obtuse at tip, and not very broad ; 

 mesothoracic epimera reduced to a mere lamina hardly visible from 

 above.

ELPIDUS, n. gen. 

 Mentum ovate, very convex, so broadly scooped out laterally for the 

 insertion of the labial palps that the ligular part is at the back of the 

 transverse excavation, and projects as a small, bi-lobate process ; last 

 joint of labial palps very thickly swollen in the lower part, and sub- 

 acuminate at tip, maxillae short, weak, the galea very small, hardly 

 longer than broad and surmounted by a few setae ; last joint of 

 maxillary palps very l'»ng, fusiform, but somewhat blunted at the tip ; 

 clypeus straight, em urinate in front, plainly concave in both sexes;
