Bnovx.— Descriptions of New Species of Coleoptera. 978 
Head, dark red; coarsely punctured; a row of elongate yellow scales 
placed in a curved line near inner margin of each eye, Thorax, quadrate ; 
broader than long; somewhat produced laterally after the middle ; coarsely 
punctured, except a smooth space on the centre; rather convex ; orna- 
mented with elongate yellow scales, mostly directed forwards, most closely 
set near lateral margins; colour similar to that of head. Elytra, thrice as 
long as thorax ; slightly margined ; coarsely punctured ; suture, distinct ; of 
a dark red colour, ornamented with scales similar in form and colour to 
- those on the thorax, and so disposed as to give them a chequered appear- 
ance when viewed with the naked eye. Femore, moderately thickened ; 
tibie, spined, and serrated on the outside ; Setose. Length, 74 lines. 
Breadth, 3 lines. 
Though not the largest, this species is decidedly the finest of the New 
Zealand Lucanide; is well differentiated from White's M. irroratus, the most 
nearly allied species, by its larger size, comparatively smaller antenne, and 
peculiarly formed thorax. Mr. C. M. Wakefield, when in Canterbury, found 
one specimen clinging to the under-side of a log, whilst I obtained one at 
Stoke Point, in 1874, and two others in the vicinity of Tairua in the follow- 
ing year. 
Ancistropterus pilosus. 
Head, granulated, fuscous ; beak, ferruginous; eyes, prominent and 
coarsely facetted. Thorax, dull black, coarsely granulated. Elytra, almost 
black ; ten rows of deep punctures on each ; humeral angles, produced, but 
not so acutely pointed as in 4. quadrispinosus, only slightly directed poste- 
riorly, the points red. The tubercles placed after the middle are ferrugi- 
nous; apices, fuscous ; the whole surface clothed with fuscous hairs, with a 
few whitish bristles intermingled. Antenne, bright brown ; legs, fuscous, 
lighter near the joints. Length, 33 lines. 
I discovered this species in February last at Tairua, but have only one 
example of it. It may be at once distinguished from the other species of 
this genus by its granulated head and thorax, and pubescent elytra. 
Platyomida niger. 
Somewhat similar in form to White’s P. binodes, but rather more elon- 
gate, with more parallel-sided elytra, and the thorax rather narrower in 
front. Head and beak, granulated, with an indistinctly defined ridge extend- 
ing from between the eyes to tip of beak. Thorax, covered with small obtuse 
tubercles, so deposed as to give it the appearance of being transversely 
granulated ; a longitudinal fovea near anterior margin, but not extending 
so far down as in P. binodes. Each elytron impressed with eleven longitudi- 
nal rows of large punctures ; the interstices finely punctured ; each elytron 
with a compressed tubercle near the suture beyond the middle ; a few thick
