at apex: prothorax subquadrate, wider than long; sides anteriorly 
‘moderately incurved, posteriorly subparallel, or very slightly sinuously 
contracted ; apex arcuate-emarginate, and distinctly margined throughout; . 
front angles a little depressed, obtuse; base closely applied to and over- — 
lapping the base of the elytra, strongly emarginate at the middle, the hind 
angles obtuse ; more or less finely, and somewhat irregularly, punctured, 
more or less distinctly wrinkled at the sides and at the hind angles, distinctly _ 
(especially at the sides) but very finely pubescent ; the whole surface more 
or less uneven by numerous irregular foveate impressions, the most constant 
being the rounded fovea at each side of the middle at the basal margin : 
scutellum rather large, convex, punctured, transversely curvilinearly trian- 
gular: elytra but little broader at base than the base of prothorax, narrowed 
behind, finely pubescent, with numerous strie, these sometimes a little 
irre ,more or less finely impressed, but very rarely (in but one out of 
the ten examples before me) distinctly punctured; the intervals (except at 
the apex) flat Nery finely and closely muricate-punctate, here and there 
interrupted by irregular transverse impressions, which sometimes assume 
the form of rounded fovew : underside bronzed brown, finely pubescent : 
prosternum slightly compressed in front of the coxe, its process rather 
narrow, convex, finely margined at the sides, very obtuse and not produced 
behind ; intercoxal process wide, subtruncate at apex: legs reddish-brown ; 
tarsi and antenne ferruginous; the four front tarsi distinctly more eepmnded 
in male than in female: inner edge of hind tibie fringed with longish hairs 
in the male. 
Length 84-44 lines. 
Hab. New Zealand. Ten examples. 
There are some points of resemblance, especially in the form of the 
head, between this species and the Cymbeba dissimilis of Pascoe; and, did I 
hold that genus unmistakably distinct from Adeliwm, I might be inclined to 
place this with it as a second species. It has not, however, the produced 
and pointed prosternal process, the distinctly marked-off epipleure of the 
elytra, nor the apically rounded intercoxal process, as in Cymbeba dissimilis. 
I possess examples of this latter coming from Cape York, New Hebrides, 
and New Caledonia. 
Amarygmus zealandicus, n. sp. 
Form and general aspect of A. hydrophiloides, Fairm. ; but differs from 
it, and from all the other species of the genus known to me, in having the 
four hind tibie attenuate at the base, and then expanded, and strongly 
sinuous (almost broadly dentate in the hind pair) at the inner margin. 
Prothorax green, with a slight bluish tinge, brassy at the sides; elytra 
green, with a brassy tinge, the sutural region a little coppery; head and
