Broun. — The Coleoptera of the Kermadec Islands. 301 



base, quite glossy ; regularly and coarsely striate-punctate, interstices 

 with fine distant punctures, closer alongside the suture than elsewhere. 



Antennfe medially inserted, indistinctly pubescent, the rather narrow 

 club more distinctly ; scape slightly flexuous ; 2nd joint of funiculus of 

 nearly the same length as the basal one, joints 3-5 about as long as broad. 



Legs pubescent, the inner extremity of the front tibite particularly ; 

 tarsi densely setose, their 3rd joint with well-developed lobes. 



Underside nitid, piceous, coarsely punctured as far as the extremity 

 of the 2nd ventral segment, the 5th more finely and closely but without 

 depressions. Prosternum slightly emarginate. Anterior coxae subcontigu- 

 ous, the intermediate moderately, posterior widely separated. Meta- 

 sternum and basal ventral segment broadly but not at all deeply impressed, 

 2nd segment indefinitely delimited in front. 



Materially dift'erent from the typical species {M. huttoni) in appear- 

 ance. The thorax rather larger, cylindric rather than ovate, and rather 

 more coarsely and closely and slightly rugosely punctured. The elytra 

 are a little narrower near the apex, and their coarser sculpture is continued 

 to the extremity. This species, however, agrees structurally.

Sunday Island. 



Found on the leaves of Solanmn by Mr. W. L. Wallace. Only two 

 specimens. 



Group Platypid^. 



Platypus posticus, sp. nov. 



Cylindric, rather slender, moderately shining, rufo-fuscous. 



Thorax oblong, apex truncate, base medially angulate, each side in- 

 curved behind the middle and with a sUght obtuse angulation there ; its 

 surface very finely and indistinctly punctate, with minutely sculptured 

 intervals ; there are a few larger, yet fine, punctures near the base, just in 

 front of the latter, at the middle ; there is a small fovea from which an in- 

 definite hnear impression proceeds forwards ; it bears a few slender yellowish 

 hairs. Elytra parallel-sided, base bi-arcuate ; on each elytron there is a 

 shallow basal impression near the middle, and a more slender one nearer 

 the suture, which can hardly be termed strise ; along the disc 5 or 6 series 

 of very fine punctures can be seen, the suture is depressed ; near the ex- 

 tremity there are 6 or 7 deep grooves, on each the outer angle is distinctly 

 dentiform and projecting, the suture slightly so, this posterior portion bears 

 fine but obvious yellow pubescence. Pygidium nearly vertical, and only 

 visible from behind. 



Described from a single damaged specimen. Several were taken from 

 the trunk of a dead nikau, but, mifortunately, made their escape by eating 

 through the cork of the tube in which they had been placed. It is nearly 

 as slender as P. gracilis, but with very different sculpture.

Raoul Island. 



Found by Mr. Wallace. 



Group EuMOLPiD^, 

 Peniticus wallacei, sp. nov. 



Robust, shining, seneo-fuscous, head and thorax darker than the elytra, 

 legs fusco-testaceous, tibiae usually darker than the femora and tarsi, an- 

 tennae rufo-fuscous.
