y so small, and which might elsewhere be deemed
inadequate to the establishment of genera, become important in this
remarkable family, from their being confirmed by the structure of the
trophi, and the strong distinctions exhibited in their females in every
instance that has yet presented itself to me, wherever I have had the
certainty of specific identity in these heterogynous insects, from the
direct observation of my friends in Australia.

Oncorhinus xanthospilos, Shuckard.

Black--clypeus, mandibles, lower portion of face in front of eyes, a
narrow streak above and behind them--anterior margin of collar, tegulae,
tubercles and adjacent part of epimerae--a round spot on each side of
each segment of the abdomen, except the terminal one--apex of the femora,
the tibiae and tarsi, all yellow; the posterior tibiae being only brown
within, and the extreme apex of the joints of their tarsi also brown.

Habitat King George's Sound. Length 11 lines, expansion of the wing 18
lines.

This is a unique species in the genus as far as I have yet had the
opportunity of ascertaining.

five-jointed, second joint longest, third, fourth and fifth, somewhat
thickened and nearly equal; beak reaching to base of last pair of legs,

the line separating it from hemelytra very indistinct; hemelytra without
a membrane at the end; tibiae very spiny; abdomen broadest behind; tarsi
