than in the specimen described, but as I can find no other 
difference I think the variation of form is probably sexual.

S. vagans, sp. nov. Late ovalis ; pubescens ; modice convexus ; 
minus nitidus ; niger, vel nigro-piceus, antennis palpis pedi-

elytris sat fortiter minus crebre, punctulatis; prosterno 
medio angusto planato; lamellis abdominalibus integris.

This minute species seems to be a typical Scymnus in all 
respects except in having its abdominal lamelle entire (I have 
not, however, succeeded in counting the joints in its antennz). 
It is at once distinguished from its Australian described con- 
geners by its extremely small size. 
Victoria and N.S. Wales ; taken by Mr. Koebele. 
The following tabulation of the hitherto described Australian 
Scymni will probably aid in the identification of the foregoing 
new species. 
A. Abdominal lamelle incomplete. 
B. First ventral suture enfeebled in the middle. 
C. Pubescence short and fairly close. 
D. Prosternum not simple. 
EK. Puncturation of elytra more or less fine and close (not 
less so, é.g., than in Ss. discoideus, I1.). 
F. Prosternal ridge entire. 
G. Form more or less widely oval. 
H. Puncturation of elytra excessively fine (scarcely 
visible), especially near suture. 
I. Elytra blackish, without sharply defined pale mark- 
ings (prothorax without sharply defined markings). 
J. Suture finely carinate be- 
hind middle ... simplex, Blackb. 
JJ. Suturenotat all carinate 
behind middle ... lubricus, Blackb. 
IY. Elytra not as I (or pro- 
thorax with sharply 
defined markings). 
J. Base of prothorax not 
with an  emarginate 
lobe. 
K. Elytra blackish, at 
least on a large space 
around the scutellum.
