 are situatnl verv <lose to one another antl to the «entral tubercle, the whole of the .snuill 

 triangular concave frontal area being .strongly elevate«l. The snuill central part «»f the 

 mentuni is usuallv marked with a pair of more or less confluent shallow transverse grooves 

 a little U-hind, an«l a >niall deprcssinn in the nii<ldle of, the anterior margin ; but either or 

 Inith of thes«' may be faint or ab.sent ; or «uje may be so .strongly developed as to obliterate 

 the other; strong ritlges, however, are never pre.sent. The lateral ])arta of the mentum, in 

 front of the primary .scars, are glo.s.sy, punctured ami hairy throughout. The pronotum 

 has no metlian groove; its .scars are pumturcd. 'I In- elytra are more coarsely punctured 

 at flic --iilcs than above.

A numl)er of .sjiecimens from C^ueensland. N«'w South Wales (Richmond River) and

The snudl inner tubercles are situated nearly half as far from the outer tubercles as 

 the latter are from each other, and alnuist directly behind them. The ridge uniting the inner 

 ttiben-les is often ab.sent. When present it may lie clo.se in front of the frontal ridges, or 

 some di.stance in fnmt of them. The frontal area, which may thus be ahnr»st non-exi.stent 

 or of considerable .size, is smooth and glossy ; the area between it and the anterior margin of 

 the head is verj' rough. The pronot«m. mentum atid elytra resemble those of M. quaestionis.
