Tyrogetus optandus, sp. n. 
Red, tarsi and palpi yellow; sparingly clothed with short, 
depressed, yellow sete. 
Flead oval, not distinctly punctate, with a small fovea near 
each eye. Zhorax longer than broad, moderately convex, 
more narrowed in front than it is behind, its sides slightly 
rounded, its middle part but little broader than the head ; its 
surface is without distinct sculpture of any kind. Hlytra 
hardly longer than broad, gradually yet considerably narrowed 
towards the base, which does not exceed the thorax in width ; 
each elytron has a rather broad sutural stria and a less 
distinct discoidal one ; the apex is densely fringed with yellow 
hairs. Hind body longer than the wing-cases, quite as broad, 
its three basal segments marginate; the first is horizontal 
and about as long as the other deflexed segments. Legs 
elongate, slender, clothed like the body ; femora not clavate ; 
tibiz straight and simple. 
Antenne elongate, sparsely pubescent, first joint nearly 
twice the length of the second, rather stouter, both cylindric ; 
joints 3 to 7 differ but little, each is longer than broad ; 
eighth and ninth nearly quadrate, tenth nearly as long as 
it is broad, distinctly broader than the preceding ones, eleventh 
large, rather broader than the tenth, oblong-oval. 
The channel between the antennal tubercles is very narrow 
and scarcely reaches the middle of the head. 
Length #, breadth 4 line. 
Mount Pirongia. One individual only, a female, I think. 
I very much regret that I have but one mounted specimen ; 
the structure of the underside therefore cannot be studied at 
present. 
Euglyptus costifer, sp. n. 
Subopaque, chestnut-red ; tarsi and palpi yellow; clothed 
with small, depressed, yellow, scale-like setee, and also with 
some slender hairs. 
Head punctate, not as large as the thorax; vertex con- 
vex, the depression behind the antennal tubercles smooth and 
shining. Thorax rather longer than broad, more narrowed 
in front than it is behind, widest and obtusely prominent 
before the middle; its surface distinctly punctate, in front 
nearly smooth; along the middle there is a broad groove ; 
on each side, but not reaching the apex, there is an elongate 
foveiform impression ; the transverse impression near the base 
is indistinct. H/ytra longer than broad, a little narrowed
