1406 - FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
continuous all across and in the middle is strongly and angularly 
produced backward in such fashion that the strip in front of it is 
narrow close to the anterior angles and dilates gi-adually towards 
the middle, but at the middle is suddenly and triangularly pro- 
duced backward, till the apex of the tiiangle reaches back to a 
fifth of the length of the prothorax ; there is a small punctulate 
fovea near the lateral margin on either side about half-way 
between the base and apex. The elytra resemble those of the 
male except that the sculpture is altogether stronger. 
The anterior tibiae are strongly and sharply tridentate on their 
external edge as in the male. 
The mentum in both sexes is very rugose and hirsute, and 
strongly sulcate down the middle nearly to the front ; in the 
male it is moderately tuberculate on either side. The upi>er lobe 
of the maxillae is strongly dentate. 
I ha^ e seen specimens from both X. S. Wales and Victoria.
