mixed with sooty on the disk of prothorax; elytra with more 
sooty than grey hairs, the grey most numerous at the base, 
becoming sparsely sprinkled and disappearing before the apex is 
reached. Undersurface with silvery-grey pubescence with a 
yellowish tinge, densest on the legs; abdominal segments — except 
at their bases — with sooty pubescence. 
Scutellum subquadrate, slightly depressed in the middle. 
Aculeus narrowly margined, base rather broad, gradually decreas- 
ing to the apex, which is truncate. Posterior spurs equal, about 
two-fifths the length of the first tarsal joint. Length 6^, width 
1| mm

Proportioned much the same or a little broader than M. setipes, 
and with a broader aculeus. I have a number of specimens 
recently taken by Mr. Masters at Rope's Creek which agree in all 
respects with the above description, except that the colour of the 
base of the antenna and anterior legs is very obscure. 
MORDELLA ALBO-SCUTELLATA, n.sp. 
Black; antenna? piceous, basal joints piceous-red, mouth 
obscurely red, anterior legs with femora and tibiae piceous-red or 
reddish-piceous, tarsi piceous, posterior spurs obscure red; head 
(in some lights) with a steel-blue tinge. Head densely covered 
with silvery-yellow pubescence (which when looked at from the 
side appears to be parted in the middle, and one side darker than 
the other), pubescence on prothorax somewhat darker (in some 
specimens very obscure), at the base with traces of three very 
indistinct maculre (these can sometimes be followed, when the 
middle one appears almost parallel-sided, and continuous from 
base to apex). Scutellum — and elytra narrowly at the base — 
pubescent as the head, shoulders as the prothorax, the rest of the 
elytra appearing sooty, but when a light is thrown on it somewhat 
purplish. Undersurface pubescent as head; sides of metasternum, 
aculeus and abdominal segments (including a small part of the 
basal) with purplish pubescence, sides of the basal segment lighter 
than in the middle.
