The pubescence of the elytra and undersurface of this species is 
similar in character to the preceding, but it is never so brilliantly- 
silvery. 
MORDELLA jEMULA, n.sp. 
Differs from M. fugitiva in being smaller, narrower, the elytral 
pubescence less strongly marked, two small spots near apex of 
elytra, base of antennae obscurely piceous; posterior femora 
piceous-black, but distinctly lighter in colour than abdomen; and 
by the aculeus. Length 7, width 2 J mm. 
Hab.—M.t. Kosciusko (Mr. W. Raymond). 
As the four preceding species strongly resemble each other it 
may be as well to point out their chief differential characters. 
M. trivialis has the head and prothorax densely and equally 
covered with griseous pubescence, the aculeus long, narrow and 
nowhere suddenly lessened. The other three species have the 
head only covered with griseous pubescence, and that not so 
bright as in trivialis. M. Raymondi has the aculeus shorter than 
in trivialis, strongly lessened about its middle, then very gradually 
decreasing in width to apex, which is truncate. M. fugitiva has 
the aculeus short, suddenly lessened at about its middle, rather 
broad and parallel-sided from there to apex, the apex truncate. 
M. cemula has the aculeus fully as long, but not so narrow as that 
of trivialis, its sides very feebly diminishing in width from base 
to apex, apex sharply truncate. 
MORDELLA MASTERSI, n.sp. 
Black; posterior spurs testaceous. Covered all over with 
greyish pubescence, paler and shorter on the undersurface; on the 
elytra there are very indistinct traces of markings towards the 
apex. 
Aculeus long, from the base to about the middle decreasing in 
width as the elytra, from the middle narrow, apex sharply pointed. 
Posterior spurs subequal, about two-fifths the length of the first 
tarsal joint. Length 3|-4J, width 1-1 1 mm. 
Hab.— Rope's Creek (Mr. G. Masters).
