1392 FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
at the apex of the front tibiie might almost suggest generic distinc- 
tion were it not that a similar character is feebly displayed in 
C. /ortis, which seems to be quite a typical Cycloihorax otherwise. 
A single example in flood refuse on the banks of the Torrens. 
C. Peryphoides, sp.nov. 
IMinus convexus ; niger ; antennis palpisque rufescentibus ; 
pedibus in parte ferrugineis ; prothorace vix transverse, trans 
basin punctulato baud depresso, lateribus rotundatis postice rectis, 
angulis posticis acute obtusis ; elytris vix striatis, 6-seriatim punc- 
tulatis, puncturis postice obliteratis. [Long. 2f, lat. 1 line. 
The head is somewhat narrower and more elongate than that of 
C. obsoletus, the antennae and palpi as in that species. The pro- 
thorax is not much more than half as wide as the elytra, its 
length and width nearly equal, its base and front margin of nearly 
equal width, the sides very strongly rounded but becoming straight 
just before the base where it is sharply angled, but the sides of the 
base being somewhat oblique the angles are slightly obtuse ; the 
median line is fairly marked but much abbi’eviated at both ends ; 
the basal area is not depressed (as it is in all the preceding) but is 
similarly jmnctured, the punctures being considerably larger and 
more lightly impressed than in C. obsoletus ; a strong unpunctured 
furrow runs transversely in a curve a little behind the front 
margin. On the elytra, the sutural stria is well-marked and attains 
the apex and is punctured in its anterior half ; it can scarcely 
be said that there are any more strim, but outside the sutural 
one there are five rows of punctures very similar to those of 
C. cinctipennis, and near the lateral margin the sculpture scarcely 
diflfers from the same in C. obsoletus ; the apical third part of the 
disc is perfectly Isevigate ; as in all the preceding species of 
Cyclothorax, the abbreviated scutellar stria is indicated by a short 
row of punctures between the suture and the sutural stria. In 
my example the legs are black, except the following parts which 
are reddish — the anterior and intermediate coxae and the under- 
side of the corresponding femora, the extreme base of the hind 
femora and of all the tibiae, and all the trochanters and tarsi.
