1404 FURTHER NOTES OX AUSTRALIAN COLEOPTERA, 
distant from the front of the prothorax nearly as far as the length 
of the antennal club ) ; there is a slight longitudinal concavity in 
which the puncturation of the surface is at its strongest occu- 
pying the extreme front of the disc, a small slight indication (on 
either side) of what in the male is the lateral fovea, and an 
oblique impressed line on either side a little within the posterior 
angle (this latter is possibly an indh-idual aberration). The elytra 
together are very nearly as wide as their length down the suture, 
and are (behind the middle) a quarter again as wide as, but in 
length not quite twice, the prothorax; their sculpture is very 
much as in D. Dejeani, but the second, third, fourth, and fifth 
striffi show a tendency to run in pairs. The pygidium is much 
like that of D. Dyeani, but a little more pointed at the apex. 
The external margin of the anterior tibiae is cut into three very 
Vdunt teeth. 
X.B. — Mr. Macleay informs me that the ticket on his D. 
A ustralis ^ gives ScaraboMS JvJ>a, Kirby,” as a synonym, but 
I hardly think it can be so. The only known Australian genus 
presenting the cephalic and prothoracic characters ascribed to 
S. Juha is Corynophyllv^ (C. raelas, Fairm., agrees veiy well in 
these respects) ; but the known species are much too small, and 
it is improbdVjle that Kirby could have omitted reference to the 
antennae if his insect had been a Corynophyllv^. S. Juha should 
he, I think, omitted from the AustraKan catalogue ; or, better 
still, relegated to an apj>endix.
