foveæ near front angles in marginal channel, and a third near the middle, 
from each of which proceeds an erect ferruginous bristle ; another bristle 
proceeds from each hind angle, directed backwards ; superfices with many 
very faintly impressed transverse lines. Elytra, sub-ovate, rather widest 
after the middle; strongly sinuated near apices; lateral and posterior 
margins reflexed ; dise, with seven longitudinal, distinctly punctured lines, 
but only the three nearest each side of suture reach the apices ; interstices, 
moderately convex ; the sides just beyond the seventh strie rather suddenly 
bent down, and marked with a row of irregularly formed impressions, con- 
nected together by an impressed line. These foves are largest just behind 
posterior femore ; suture, indistinct. Hairs on femore, tibie, and tarsi, 
ferruginous. Length, 61 lines. 
Of this species I have but one mutilated specimen, which I found under 
rushes in Kikuwai Forest, Tairua. 
Hister grandis. 
Form, ovate, moderately convex ; colour, black. Head, minutely pune- 
tured ; a punctured longitudinal fovea extends along inner side of each eye 
to the base. Thorax, humeral margins slightly reflexed ; a transverse punc- 
tured fovea, near anterior margin, extends as far across as the head ; from 
each terminal point there is a succession of irregular punctures along the 
lateral and posterior margins, larger and more deeply impressed near 
humeral angles, and becoming more and more minute after rounding the 
posterior angles; one round fovea near the centre of posterior margin. 
Elytra: near the humeral margin of each elytron there are three longitudi- 
nal foveæ arranged in line, and a fourth, irregular in form, close to humeral 
angle. Two longitudinal foveæ are placed near outer posterior margin, with 
a third, which is prolonged in the form of a gradually decreasing impressed 
line to within a line of the base. A deeply impressed line extends from near 
the humeral angle along the lateral and posterior margins, broader and more 
irregular in form near the middle, and terminated at the suture, up which 
it extends a short distance in the shape of a curve. The exposed segments 
of abdomen are coarsely punctured. The grooves in anterior tibiæ for the 
reception of the tarsi, when in repose, are deeply hollowed out. Length, 
4 lines. 
My unique specimen of this remarkably fine species was captured whilst 
sedately marching into the kitchen of my house at Tairua, on the 19th 
March, 1876. 
Cerathognathus zealandicus. 
In general form this species resembles M. irroratus. Mandibles, porrect 
and recurved in front; setose ; punctate. Antenne, dark red; a few 
bristles on scape, directed forwards ; leaflets, rather short, densely pilose.
