on tlie forcliead, near the eyes it is similarly irregularly 

 rugose, with a single setigerous puncture near each eye ; 

 on the vertex there are only faint transverse irregular 

 impressions. Labrum slightly notched in front and bearing 

 six setae. Eyes prominent. Antennce short, their basal four 

 joints glabrous, the others pubescent. Thorax 3f broad by 

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

 backwards, more abruptly near the base, apex subtruncate, 

 base slightly incurved, lateral margins only feebly crenulate, 

 posterior angles obtuse ; the basal fossae are situated close 

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

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

 tudinal striae, and across the disk faint linear impressions. 

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

 between the middle and the side, three indistinctly elevated 

 lines occur, 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 striae ; the lateral sculpture is not 

 coarser than that near the outside o£ the dorsum. Legs 

 moderately slender; anterior tibice with produced outer 

 angles, intermediate slightly acuminate, the posterior simple. 

 Terminal joint of maxillary palpi rather broader than in 

 M. sculpturatum. 



Underside glossy black, head with undulating sculpture, 

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

 the last segment there are 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 on 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. 

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



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

 male of Trichosternus akaroensis, which appears to be usually 

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