NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
at the suture; the hinder fascia straight at its posterior edge, 
trisinuate in front; suture from the anterior, and margin from the 
posterior fascia, with a few silvery hairs. Undersurface with 
silvery pubescence, partly denuded on meso- and metasternum; the 
abdominal segments when looked at from almost every direction 
with the sides at the apex apparently semicircularly denuded. 
Aculeus short, broad, basal two- thirds narrowly margined; apex 
narrow, truncate. Posterior spurs unequal, the longest about 
two-fifths the length of the first tarsal joint. Length 4 J, width 
1 i mm. 
II ab. — Sydney. 
This is a rare and very pretty species, easily distinguished by 
its red abdomen in striking constrast to the general colour. 
MORDELLA PALLIDA. 
Pale testaceous, elytra slightly darker, their apices darker still; 
abdominal segments piceous, their apices and sides and the aculeus 
piceous-red; eyes black; antenna? — except at base — slightly darker 
tli an head; posterior tibise and tarsi tipped with piceous, inter- 
mediate to a less noticeable extent, anterior not at all. Covered 
all over (but shortest and sparsest on meso- and metasternum) 
with short, yellowish, silky pubescence. Meso- and metasternum 
distinctly punctate. 
Aculeus very short, rather flat, truncate at apex. Posterior 
spurs unequal, longest nearly three-fourths the length of the first 
tarsal joint. Length 2^, width § (vix) mm. 
Hah. — Galston; on flowers of "White Gum." 
A species easily recognisable by its pale colour, with dark 
abdomen and the absence of macular, and by the great length of 
its posterior spurs. 
MORDELLA WATERHOUSEI, 11. Sp. 
Testaceous; elytra with a zigzag fascia slightly behind the 
middle — forming three Y's in front and four behind (one specimen 
has it broader, more confused, and extending slightly in front of 
the middle) — and the apical fourth piceous-brown; abdominal
