Description. 
Beetle.—Slightly elongated, brown, with the lower dorsal 
portions of the elytra lighter coloured, occasionally almost 
reddish. The stiff hairs on the front portion of the clypeus 
always few in number and very short. 10-jointed antenna, tke 
upper portions not fringed with hair; the second joint of the 
club less than one anda half times as large as long. Front 
edge of the prothorax armed with more or less pointed teeth, 
not set very close together, the middle ones being more gaping 
than the outer. Posterior portion of the pronotum strongly and 
thickly punctate (pitted), but the pits do not join. Elytra 
covered with short bristly hairs becoming denser on their 
posterior declivity. Elytra are thickly and densely pitted, more 
deeply so on their anterior portions. This beetle is very like 
the one shown in PI. VIII, fig. 1, a, but is smaller.

It was not present amongst the D. pzlzfrons bred out of the 
-bamboos obtained in the Siwalik forests. It is apparently very
