latiori, «quali, sparsius dupliciter (subtiliter et minus sub- 
tiliter) punctulato, angulis omnibus rotundatis; elytris 
sparsim punctulatis (horum puncturis prothoracis puncturis 
majoribus similibus). Long., 24 1.; lat., 22 1. 
The very brief description of Chrysomela nitidipennis, Boisd., 
reads as if it might well have been founded on this species, 
especially in consideration of Boisd. referring to the small size of 
the insect before him in comparison with the other Australian 
Chrysomele that he described. In describing Plagiodera Lowner 
Mr. Baly does not refer to that insect as differing structurally 
from typical species of Plagiodera,—so that very likely the 
present insect has nothing to do with it; nevertheless his des- 
cription (apart from that obstacle) reads much like that ofa 
species resembling that Iam now describing. If it should be 
generically identical Mr. Baly’s species differs specifically from 
mine by the black apex of its antennz and back of its head, the 
dark colouring of part of its under-surface, the (implied) absence 
of green margin on its elytra, its prothorax more than three 
times as wide as long, and bearing fovea-like impressions, and the 
lateral portion of its elytra ‘‘ dilated and separated from the disc 
by a shallow depression.”

MONOLEPTA. 
M. fasciatipennis, Blackb. I have recently taken near the 
original locality some more examples of this species which prove 
it to be variable to the extent of invalidating the character on 
which in my tabulation of Monolepta (Tr. R. Soc., 8.A., 1896, 
pp. 100, &c.), I distinguished it from WM. picticollis, as the 
elytral fascia is now found to be liable to much abbreviation at 
both ends. I therefore substitute the following for the distinc- 
tion that was printed (Joc. cit., p. 100) in the tabulation :— 
EK. Sulcus between the eyes (looked at obliquely 
from behind) strongly curved (with its con- 
vexity directed forward) ... = es 
EE. Sulcus between the eyes (looked at obliquely 
from behind) straight 3 picticollis, Blackb. 
From whatever point of view the frontal sulcus is looked at it 
is seen to be quite different in the above two species, but as its 
shape looks a little difierent in each according to the point of 
observation, I have selected a particular point of view for charac- 
terising it,—viz., that from which its hind edge is most conspicu- 
ous. It is also to be noted that looked at from the above- 
mentioned point of view the space in front of the sulcus is seen 
to be in fasciatipennis (but not in picticollis) broken up into 
about three quasi-tubercles. In my description of P. picticollis I 
fasciatipennis, Blackb.
