NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
median line. Sides of prothorax very narrowly edged with white; 
apex a little more broadly, from its middle a narrow stripe 
extending a little more than a third from the apex, there is also 
a small spot on each side; there are ten free or nearly free spots 
— four at the base, of which the two inner are the smallest; two 
on each side of the narrow stripe in front, in a line with each 
other, and one on each side of the middle behind it. Elytra not 
bordered at the base, each with seven small spots — one close to 
the scutellum, the smallest spot between it and the shoulder, two 
in a line behind them, the inner one not close to the suture; the 
outer close to the side (forming with a spot on the meso- and 
another on the metasternum a small triangle), a round spot close 
to the suture at about the exact middle, the largest spot in a 
straight line behind about a fourth from the apex, the last is 
close to and a little behind it at the side, the two forming an 
nterrupted irregular oblique S. Each of the abdominal segments 
with four white spots, the two inner of each of which are narrow, and 
but little separated. Meso- and metasternum (except at the sides) 
pubescent as the head. A little white at the base of the aculeus. 
Aculeus long, narrow; apex very sharply pointed, margined 
almost to the apex. Posterior spurs equal, about two-fifths of the 
length of the first tarsal joint. Length 12, width 3 J mm.* 
Hah. — Galston; on flowers of Bursaria spinosa (Dumbrell and 
Lea). 
From M. multiguttata the present species may be distinguished 
by its broader form, more distinctly margined aculeus, more 
elongate abdominal spots; by its smaller elytral spots, those near 
the apex nearly separated or not at all joined together as in that 
species; the small spot forming a triangle with the two behind the 
basal ones is wanting in this species; the spots on the prothorax 
also cover much less surface. 
MORDELLA 1 8-MACULATA, n.Sp. 
Black, legs scarcely lighter in colour. Head with silvery-grey 
pubescence which is parted in the middle. Prothorax with 
* The lengths given are to the apex of aculeus.
