on tlic forclicad, near tlio oyrs it is siinilaily iri'r<^iilarly 

 rugose, with a single sotigcrons jinncturc near each eye ; 

 on the vertex there are only faint transverse irregular 

 impressions. Lahrum sliglitly notched in front and bearing 

 six setae. Ktjes prominent. AiitcniKV short, their basal four 

 joitits glabrous, the others pubescent. Thorax 3^ broad by 

 3 lines long, widest near the front, rather gradually narrowed 

 backwards, more abruptly near the base, apex subtruncate, 

 base sliglitly incurved, lateral margins only feebly crenulate, 

 posterior angles obtuse ; tlie basal foss;e are situated close 

 to the sides, but do not reach the hind margin, the discoidal 

 groove is well marked ; in front there arc some fine longi- 

 tudinal stria.% and across the disk faint linear impressions. 

 Elytra elongate-oval, with rounded shonlders ; on each, 

 ])etwccn the middle and the side, three indistinctly elevated 

 lines occnr, the intervening spaces are moderately coarsely 

 and closely punctured and become rugose behind, nearer 

 the smooth flat suture the punctures are finer and irregular, 

 but do not form series or stride : the lateral sculjiture is not 

 coarser than that near the outside of the dorsum. Leys 

 moderately slender ; anterior tibice with pioduced outer 

 angles, intermediate slightly acuminate, the posterior simple. 

 Terminal joint of maxillary ])alpi rather broader than in 

 M. scu//jli&aium. • 



UiuUrside glossy black, head with undulating sculpture, 

 the rest of the body nearly smooth. At the extremity of 

 the last segment there arc two setigerous punctures on each 

 side of the middle, and, on one side, there is an additional 

 pair, which, however, in my specimen, is wanting ou the 

 other side.

Akaroa. 



This may be be placed near M. alternans and M. Suteri ; 

 it is, however, much larger than either of these and 

 differently sculptured. The name of its discoverer, Mr. J. J. 

 AValker, F.L.S., has been attached to the species. 



Obs. — At the same time Mr. Walker supplied me with the 

 male of Trichosiernvs akaroensis, which appears to be usually 

 smaller than the other sex^ measuring only 10 x 3^ lines.
