(D.) DESCRIPTION AND FIGURES OF FOUR NEW SPECIES OF AUSTRALIAN INSECTS.
BY ADAM WHITE, ESQ. M.E.S.
The four insects here figured and described are, as far as I am aware,
new. Petasida, and Tettigarcta are interesting in the shape of the
Thorax, differing widely from that in any of the allied genera, while the
new species of Eurybrachys and Chrysopa are striking from their colouring
and marks.
PETASIDA EPHIPPIGERA, pl. 4. fig. 1.
Thorax much dilated behind, depressed and rounded at the end; the side
deeply sinuated behind; head pointed, antennae long; of a yellowish
orange; antennae with a few greenish rings, cheek below the eye with a
greenish line, head above with a longitudinal greenish line. Thorax with
a slight keel down the middle, wrinkled behind of a dusky blueish green,
a large patch of an orange colour on each side in front, and a small spot
of the same colour on each edge of the produced part at base; elytra
orange with numerous black spots, and black at the tip, lower wings pale
orange at the base, clouded with black at the tip; abdomen orange,
slightly ringed with green; legs orange, with three greenish spots on the
outside of the femora of hind legs.
Length 1 inch 9 lines.
Hab. Australia.
CHRYSOPA MACULIPENNIS, pl. 4. fig. 2.
Head red, with a black spot on the crown; antennae short brownish black;
thorax hairy; thorax, abdomen, and legs, brownish black.
