The described Australian species of J/onolepta are now so 
numerous that it seems desirable to attempt a tabular statement 
of their characters. In the following table I have been obliged 
to rely more upon distinctions of color and markings than I alto- 
gether like doing, but this is due to the fact that a good many 
species probably attributable to Monolepta were described by the 
earlier authors in terms which gave no information regarding 
them except in respect of their colors and markings and it seems 
desirable to include these in a tabular arrangement although 
there are only two or three of them that I have been able to 
identify as among the species before me. Ido not think that 
this is a very important matter, however, as I find that few 
species of Aonolepta vary too much to be confidently separated 
by such broad distinctions of color and marking as [ have made 
use of. 
A. Elytra with sharply defined markings. 
B. The elytral markings transverse. 
C. Base and apex of elytra not concolorous. 
D. Elytra red in front, dark behind. 
E. Abdomen fulvous .. 
EE. Abdomen black . 
DD. Elytra dark in front, red behind 
CC. Base (at least in its scutellar region) and 
apex of elytra concolorous. 
D. The base and apex entirely black. 
EK. An entire median pale fascia : 
EE. The pale facia not reaching the 
lateral margins 
DD. Base black around the scutellum, red 
laterally ; apex black. 
K, The basal red of the elytra is an 
isolated spot... 
KE. The basal red of the elytra i is widely 
connected with the median red 
portion 
BB. The elytral markings longitudinal. 
C. The marking consists in the suture being 
black. 
D. Puncturation of prothorax indistinct or 
at least very feebly impressed. 
E. Underside black. 
F. Species of normal form.
