I am likewise indebted to Captain Boys for sending me his 
specimen of this new and very distinct species. The following is 
Captain B.’s description :— 
“Length 7-20ths of an inch; body brown, deeper in the middle 
of the elytra. Antenne of two joints, of which the last is large, 
cuspiform, and having dentated edges, with a scallop between each 
tooth ; apex rounded exteriorly : basal angle produced, acuminate, 
and forming a tooth at the end of the superior margins. Lower 
portions carinated ; front view resembling the bows of a boat ; head 
light brown, rounded posteriorly, emarginate in front, sunk nearly 
to the thorax, and bearing a minute depression in the centre of its 
upper part in the form of a diminutive horse-shoe. Eyes round 
when viewed from above, reniform when seen in flank. Thorax 
suboctagonal, with rounded margins anteriorly, angulated and 
scalloped at the corners posteriorly, bisected in its centre, the 
posterior portion bearing a strongly produced emargination, which 
crosses transversely in the form of a bracket. Tarsi simple, cylin- 
drical, the last longest, the first very small, almost invisible ; of 
five joints in each leg, all of which are furnished with hairs 
beneath ; elytra truncated posteriorly, of a uniform width through- 
out, slightly depressed ; body oblong flattened ; palpi conical, not 
very salient; maxillary ones tumid at the base and over-arching 
the labials. Taken on a heap of manure at Plassie, near 
Mhow.” 
Fig. 1 a represents the head and antenne seen sideways, and 1
