I have seen numerous examples of this species and scarcely 
two of them are quite similar to each other in color and markings 
of the elytra. The elytra of a light colored example are pale red 
with an ill defined dark common patch around the scutellum and 
another about the middle. Ina series of examples these dark 
patches more or less increase in size and vary into black until in 
extreme specimens they coalesce and spread out to cover the 
whole elytra. The great enfeeblement of the sculpture on the 
apical third of the elytra is a conspicuous character. 
Victoria ; mountainous districts. 
A. laticollis, sp. nov. Mas. Sat breviter ovalis; sat nitida ; 
rufo-testacea, elytris (maculatim) et antennis (apicem sum- 
mum versus plus minusve) infuscatis ; capite coriaceo, inter 
oculos sulcato; antennis corporis dimidio longitudine vix 
eequalibus, articulis fere ut A. collaris ; prothorace quam 
longiori plus quam duplo latiori, antice haud angustato, sat 
crebre sat fortiter punctulato, transversim et utrinque longi- 
tudinaliter profunde sulcato, sulcis longitudinalibus normali- 
bus, lateribus vix arcuatis, angulis anticis subtruncatis 
paullo pone marginem anticum extrorsum distincte acutis ; 
elytris ut A. collaris sculpturatis ; tibiis posticis extus ante 
apicem late distincte angulatis. Long., 1—143 1; lat., 
3 ']. 
Femine tibiis posticis haud angulatis. 
Near A. collaris but differing inter alia in color and markings, 
in the prothorax not narrowed in front and with longitudinal 
sulci less wide and in the evident external angulation of the male 
hind tibiz. The infuscate blotches on the elytra are ill-defined 
and variable ; they usually consist of an elongate discoidal blotch 
near the base and a larger one somewhat behind the middle. 
S. Australia ; near Quorn. 
PLECTROSCELIS. 
The task of dealing with the Australian species of this genus 
presents exteme difficulty owing to the fact that a number of 
species (12) have been described by Dr. Baly in such fashion that 
it is impossible to identify them with any confidence from the 
descriptions ; for though the descriptions are fairly detailed, 
scarcely any are more than bare descriptions, and the absence of 
comparison with other species causes the utmost difficulty in 
forming any clear idea of the insects they relate to. I have asso- 
ciated many of Dr. Baly’s names with insects in my collection, 
but with so much doubt that I cannot venture on making confi- 
dent use of my identifications for the purposes of this memoir. 
Hence I am obliged also to pass unnoticed some species in my
