Mas: prosterno fere undique profunde arguteque punctato. 
This species, of which I am acquainted with only a single male, is very dis- 
tinct, though looking at first sight like a small C&. hirta. The prosternal structure 
and sculpture is, however, markedly different ; in the male sex of Ci. humilis and of 
(CE. hirta, the prosternum in front of the coxz is divided by a transverse depression 
into two parts, the anterior of which is polished, and the posterior traversed by 
some obsolete wrinkles, the sides of the prothorax being punctate ; in the present 
species the anterior part is very much reduced in size, and the posterior part is 
entirely covered, like the sides of the thorax, by a coarse deep punctuation. The 
supplementary concealed anal segment is very different in its form from that of 
the two species mentioned, the dorsal plate being broad and short, gently rounded 
behind, not emarginate in the middle. As other characters, it may be mentioned 
that the thoracic rug are not so deep and regular as in the other species of this 
group, that the sides of the thorax are rounded, and that the legs, including the 
tarsi, are entirely pale. 
Greymouth, Belfrage. I have two female examples from Picton, which I have little doubt pertain 
to this species, but as they were not found in the same district, and present some differences, it is 
advisable to consider the species as established on the male only. These examples are 17 or 18 m.m. 
long, darker in colour, with the thorax straight at the sides; the prosternum and sides of the thorax 
without true punctuation. 
(Emona ineequalis, n. sp.—Ferruginea, griseo-vestita, antennis pedibusque cum 
tarsis concoloribus ; prothorace cylindrico, parum profunde rugoso, nec tuberculato 
neque transyersim plicato. Long. 15 m.m. 
Comparing the male of this species with that sex of CE. plicicollis, it will be found 
that though exceedingly similar, the present species has the sculpture of the prono- 
tum obsolete, while the sexual punctuation on the sides of the thorax is a little 
coarser and denser. The other characters are the same as in CE. plicicollis, the 
prosternal punctuation being equally very strongly developed, and the supplemen- 
tary apical segment of the males similar. 
Picton. Helms; two examples. 
(Emona simpliciollis, Broun.——Ferruginea, griseo-vestita, antennis pedibusque 
cum tarsis concoloribus ; prothorace minus cylindrico, subquadrato, haud plicato, 
versus angulos obsolete tuberculato. Long. 12-14 m.m. 
The thorax is just about as broad as it is long ; it has no tranverse grooves, but 
at each side near the front there is a slightly raised shining tubercular space, and 
nearer the middle, nearly in a line with it a larger rugose elevation ; on the middle
