1432 FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
latiori, basi quam margine antico vix latiori, lateribus (pone 
medium le\'iter angulatim dilatatis postice sinuatis) incrassatis 
intus fortiter anguste sulcatis, basi incrassata baud bisinuata, 
angulis anticis I'otundato-obtusis \dx productis, angulis posticis 
parvis acutis extrorsum retrorsumque inclinatis, dorso nec foveato 
nec canaliculate ; elytris baud striatis, seidatim punctulatis, punctis 
modicis parvisque intermixtis, interstitiis planis minute coriaceis 
et punctulatis, basi late marginata ; mandibulis apice Vjifidis.

Tbe mentum is moderately transverse, widely notched in front, 
finely punctulate, devoid of bairs ; gular furrow extremely strong 
and placed ratber far back ; prosternal process preceded by a 
fuiTOw (as in H. Orcns, Pasc.), its middle carina narrow and 
produced behind slightly beyond the lateral carinse ; third and 
fourth ventral segments slightly sinuous behind ; epistomal suture 
fairly defined and arched ; labrum scarcely emarginate in front ; 
3rd joint of antenme decidedly longer than 4th ; scutellnm very 
small. 
The lateral margin of the prothorax is strongly thickened in its 
front third, and then is suddenly attenuated, thickening out again 
immediately in a kind of slight angular dilatation behind which it 
again becomes attenuated. The interstices of the elytra are 
perfectly flat except at the extreme base where they are very 
slightly convex ; there is no trace of the large punctures near the 
scntellum on the first interstice that are found in many species of 
tlie genus ; the shoulders are roundly obtuse and not prominent, 
the sides scarcely sinuous behind. The curvature of the anterior 
tibia? is very slight. 
The non-striate elytra marked with rows of mingled small and 
larger punctures, flat finely punctulate interstices, non-prominent 
shoulders, non-sinuate elytral apices, black legs, bifid man- 
dibles, tfcc., taken together will distinguish this species from its 
congeners.
