86 On New Zealand Coleoptera. 
Head immersed up to the eyes. Thorax strongly trans- 
verse, being twice as broad as long, posterior angles rect- 
angular, the anterior obtuse but prominent, apex widely 
incurved. Scutellum distinct, triangular. Hlytra ample, 
broader and five times longer than thorax. 
Notwithstanding evident discrepancies, this genus should, 
I think, be located near Alema in the New Zealand list. The 
structure of the underside in the only mounted specimen 
extant cannot, at present, be ascertained. 
Eualema Walkeri. sp. n. 
Suboblong, convex, nude, variegate, shining; head and 
thorax irregularly fusco-testaceous; elytra testaceous, but 
with a small detached spot on each shoulder, a broad oblique 
space extending from each of these to the suture, an irre- 
gularly formed mark at each side reaching from the shoulder 
to just beyond the hind thigh, and a large space on the 
posterior declivity glossy seneo-fuscous, all these marks of 
more or less ragged outline, but always conspicuous ; legs 
testaceous, but with a dark spot at the base of each tibia. 
Head finely and rather indefinitely punctured. Antenne 
finely pubescent, basal four joints piceous, but with the base 
of each quite red, the others are nearly ferruginous. Thorax 
very slightly uneven above, moderately finely and irregularly 
punctured, finely margined throughout, its sides not quite 
straight, being widest at the middle and a little narrowed 
towards the front and base. Seutellum smooth. Llytra 
wider than thorax at the base, the humeral angles rounded, 
their sides very little curved, the posterior portion sinuously 
narrowed so that the obtuse apices appear prominent: they 
are not striate, but bear series of fine punctures; these, how- 
ever, are almost entirely absent from the dark polished 
lateral and apical marks. 
Length 4, breadth 2 lines.

This is without doubt the most conspicuous of the New 
Zealand Phytophaga. I have named it after its discoverer, 
Mr. J. J. Walker, F.L.S., of H.M.S. ‘ Ringarooma,’
