The following tabular statement will probably assist in dis- 
tinguishing the species of this genus :— 
A. Mesosternum not carinate. 
B. Prothorax of uniform (or nearly so) piceous 
color. 
C. Apex of elytra sanguineous. 
D. Puncturation of head sparse. 
E. Lateral border of elytra matey 
sanguineous : 
EE. Apex only of elytra sanguineous 
DD. Puncturation of head close 
CC. Apex of elytra not sanguineous. 
D. Head sparsely punctured... 
DD. Head closely punctured E 
BB. Prothorax with a large testaceous or fulvous 
blotch on either side. 
C. Apex of elytra sanguineous. 
D. Elytra zeneous : 
DD. Elytra pitchy black ae 
CC. Elytra of uniform piceous color ... 
AA. Mesosternum carinate. 
B. Prothorax red (or with only some basal in- 
fuscation) ¥ 
BB. Prothorax piceous, a large pallid blotch on 
either side & 
BBB. Prothorax uniformly piceous or black

S. operosus, sp. nov. Ovalis; sat nitidus; pube albida vestitus, 
hac ineequaliter distributa (ie. hic et illic ut macule vel 
fascize condensata); niger, antennis palpis tibiis tarsisque 
flavis; crebre subtilissime punctulatus; prosterno medio 
longitudinaliter depresso ; spatio depresso sat lato antrorsum 
leviter angustato antice obtuso utrinque subtiliter carinato ; 
lamellis abdominalibus haud integris; sutura postice sub- 
tiliter carinata. lLong., 1 1.; lat., 21. 
This species is recognisable by its entirely black upper surface 
with white pubescence arranged in patches; these form a narrow 
more or less interrupted lateral border which emits a branch from 
below the shoulders running about halfway across the elytron 
and another behind the middle of zigzag form running inter- 
ruptedly to the suture. In my tabulation of Scymnus (Tr. B.S., 
S.A., 1892, pp. 248, &c.) the present species falls beside S. simplex, 
Blackb., from which its color and the peculiar arrangement of 
its pubescence at once separate it.

S. brisbanensis, sp. nov. Ovalis; sat nitidus; pube albido- 
fulvescenti vestitus; niger, prothorace ad latera et elytris 
apicem versus dilutioribus, antennis palpis tarsisque flavis ; 
crebre subtilissime punctulatus; prosterno medio longi-
