This species must resemble P.. submetallescens, Baly, in size 
and color but it differs from the description of that insect by the 
front angles of its prothorax being not in the least directed out- 
ward and the interstices of its elytra not being costate at the 
sides and apex. It is said to be destructive to vegetation.

P. propinqua, Baly. A species occurring somewhat plentifully 
near Adelaide is, I have little doubt, this insect. I expect that 
P. Wilsoni, Baly, is a mere variety. Unfortunately Dr. Baly has 
made no comparison between the two species and has used so 
nearly the same words in describing them that after a careful 
examination of the two descriptions the only clearly specified dif- 
ferences I can discover consist in IWzlsoni being a trifle smaller 
than propinqua, having somewhat darker femora, the unpunct- 
ured part of the head less rugulose and the lateral punctures one 
or two less in number. It alse seems to be implied that the 
small basal impressions on the prothorax of propinqua are want- 
ing in Wilsont and nothing is said about its front prothoracic 
angles being produced externally. JI have examples (which I 
cannot separate specifically from those that agree perfectly with 
the description of propingua) in which some of these trifling 
ditferences are apparent. P. propinqua appears to me to be a 
variable insect widely distributed in Southern Australia dis- 
tinguishable from its congeners most readily by the sculpture of 
its head ; the middle part is finely strigose or finely rugulose and 
almost impunctate, but there are a few large coarse punctures on 
each side near the hindmargin of the eyes. In typical specimens 
of propinqua the front part of the middle space on the head is 
very distinctly rugulose and the basal impressions of the pro- 
thorax are quite distinctly traceable ; while the legs are entirely 
of a duil fulvous color, except the hind femora. I have this form 
only from the Adelaide district. From Yorke’s Peninsula I have 
two examples which may be Wi/soni although their legs are not 
as darkly colored as those of the type of Wilsoni seem to have - 
been. I have a number of specimens from the Port Lincoln dis-
