rounded heavily chitinous plate, to which is attached a great part of 
the strong musculature controlling the copulatory apparatus; that the 
end of the ? abdomen is broader, and lightly to deeply notched in the 
middle; that the metathorax comes far back on to the abdomen; and 
that its postero-lateral margins are usually continued beyond the 
sutural line of the hind margin, in a way that will appear later in the 
figures. The antennae are in some species alike, in others widely 
dimorphic; and show, in general, a tendency to reduction of the number 
of articles by fusion, so that, in some species, only three are present in 
the adult. In two species the ^ antenna bears an appendage. 
These antennal differences, which have been used in the past to 
separate genera, I am now forced to consider, of little importance. 
It was first pointed out to me by Mr J. D. Waterston that copulatory 
appendages on the antennae have arisen cpiite independently in several 
groups. My own observations have amply confirmed this view, so I 
make no attempt to split the present group on antennal differences. 
This will also explain why I have, in compounding the generic name, 
used Goniodes instead of Goniocotes. It may be possible to establish 
the latter genus on other grounds, but it is not justifiable to separate 
it from Goniodes on antennae alone. As type of Austrogoniodes I 
designate Goniocotes waterstoni Cummings.

The head is obtusely rounded in front, and not flatly so, as in most 
Goniodidae. The side of the forehead is continued ventral to the 
antenna into a prominent trabecular angle, which reaches almost to the 
end of the first antennal article. The eye is shghtly prominent, with a 
minute conical spine, and without a pigment spot, though all the 
remaining species have pigmented eyes. Behind the eye, the temple 
swells out broadly to a greatest width a little in front of half its length; 
then sweeps inwards and backwards, with a concave outline, to form an 
acuminate process at the side of the prothorax, reaching to more than 
half its length, and continued by a stout spinous hair which reaches to 
the metathoracic angle. The occiput is flatly convex on the prothorax, 
then curves outwards and backwards to form the inner margin of the 
acuminate process. The markings of the head are conspicuous (Text- 
fig. 2, 1). Two large triangular black blotches occur on the occiput, 
one in front of each lateral angle of the prothorax. Each of these is 
continued externally as a narrow brown band reaching the base of the 
temporal spine; internally as a narrow band along the median occipital
