The original type specimen of this species, described 
by Fabricius and figured by Olivier, is now preserved in 
the British Museum, and does not exactly agree with any 
specimens of the genus since received from Australia. 
It is a male measuring seven lines in length, not includ- 
ing the mandibles, which are one line long; the head has 
the crown gradually sloping to the anterior edge, not 
retuse, as it is in the specimens which have been named 
curvicornis ; the anterior lateral angles are oblique, shghtly 
emarginate, their posterior part forming an obtuse can- 
thus, extending a short distance into the front of the 
eyes; the head behind the eyes is wider than the mid- 
dle, and produced into an obtuse tubercle, and there 
is a raised tubercle on each side behind the outer 
base of the mandibles, which agree with those of the 
specimens, which I have termed sub-tuberculatus (Trans.
