Coleoptera from New Zealand. 289 
tate. Hyes small. Thorax nearly twice as broad as it is 
long, rather narrower in front than behind; the sides, how- 
ever, are nearly straight; the punctuation is slightly finer 
than that of the head.  Scutel/wm triangular, not broad. 
Hlytra gradually narrowed posteriorly, lateral margins broad 
at the shoulders, but becoming very narrow behind the poste- 
rior femora; the suture near the scutellum is slightly elevated ; 
they are finely punctured, but not so as to form series, and 
there are four or five ill-defined shallow striz on each. 
In shape like M. Bates?, the elytral punctuation much 
finer; the striae, though shallow and irregular, are quite 
easily detected. No. 1497 is more like this species, but it 
has a very broad short scutellum, rather smaller eyes, a longer 
and more anteriorly narrowed thorax, longer antenna, and 
‘more slender legs, and the elytra are subopaque. 
Length 2, breadth quite 1 line. 
Howick. One individual. 
Obs. 'The following remarks will help any one to separate 
the species :— 
No. 660 is the most convex ; the punctuation of the elytra 
is not arranged in lines as in No. 659; it is minutely pubes- 
cent. 
No. 661, the thorax has two large shallow basal impres- 
sions. 
No. 662 is rather narrow and elongate; its thorax is a 
good deal and quite regularly rounded at the sides, and the 
elytral margins near the shoulders are finely serrate. These 
characters will enable it to be separated from J. cacus 
(No. 657). 
Group Helopide. 
Edalus pleuralis, sp. n. 
Opaque, fuscous, the margins sometimes obscurely rufes- 
cent; legs pale reddish or testaceous, antenne dull red; 
sparingly clothed with erect infuscate sete. 
Head more or less irregularly punctured. Thorax almost 
as long as it is broad, widest before the middle, a good deal 
narrowed behind, its sides somewhat flattened and crenate, 
base sinuate; the surface rather irregularly and coarsely 
punctured, with three shallow longitudinal impressions, one 
of which is in the centre, the others (near the sides) are 
deepened at the base. Scwtellwm either short or indistinct. 
Elytra oblong, slightly narrowed towards the base, lateral 
margins more or less crenate, the shoulders slightly prominent 
and wider than the thorax; their sculpture ill-defined,
