Scydmeenus xanthopus, sp. n. 
Convex, elongate, shining, red, antenne rather pale, legs 
sordid yellow. 
Head of moderate breadth, with moderately coarse out- 
standing pubescence. Thorax much longer than broad, 
widest near the middle; with two rather small, distinctly 
separated, median fovex near the base, there are no distinct 
fove near the basal angles, but there is a large impression 
at each side ; its clothing resembles that of the head. Elytra 
ovate, widest before the middle, not very broad; apices sub- 
truncate or broadly rounded, so that the broad pygidium is 
uncovered ; there are two basal depressions, the shoulders 
appear elevated, the sutural region is unimpressed. Legs 
. elongate, but not slender; femora clavate near the apex, the 
front pair thickest; tébtw nearly straight, finely pilose. 
Antenne elongate, the last four joints dilated ; second joint 
rather longer than the first; 3 to 6 nearly alike, seventh 
rather broader than the sixth; 8 to 10 transverse; eleventh 
nearly as long as the preceding two conjointly, obtuse at the 
extremity. 
Second joint of the mawtllary palpi curved and slender; 
third nearly oviform, not at all broad; fourth short, nearly as 
thick at its base as the apex of the penultimate. yes very 
small, not at all prominent. 
This rather slender species may be known by the yellow 
legs, the exposed pygidium, and the structure of the palpi. 
I would place it in Humicrus, along with Dr. Sharp’s S. Ed- 
wardsi, if it were not for the fact that some New-Zealand species 
are just intermediate in structure between the two genera, sa 
that Humicrus will probably be abandoned as a genus.

Hunua Range. One individual only. 
Scydmenus heterarthus, sp. n. 
Elongate, moderately convex, nitid, chestnut-red, the 
pubescence and the tarsi yellow, legs and antenne fulvescent. 
Head yather small, flattened anteriorly, with long hairs 
directed backwards. Thorax longer than broad, widest before 
the middle, a good deal narrowed towards the base, which 
appears depressed, but the usual fovess seem to be absent, 
there is, however, an elongate impression at each side; the 
pubescence near the sides is rather coarse and conspicuous. 
Elytra oviform, not much rounded laterally, widest near the 
middle, covering the pygidium ; they are clothed with slender,
