176 Descriptions of new Ceylon Coleoptera, [no. 2, new series, 
tures, the central one of which is furnished with two — the lateral 
ones with one strong bristle each. The anterior tibiae are but 
slightly notched. The presternum is largely developed, reaching 
beyond the anterior coxae, obtusely acuminated and received in a 
deep excavation of the mesothorax. But I doubt that the deve- 
lopment is sufficiently large to entitle the insect to a place in the 
g. Lonchosterniis Laf. which however I have not seen in nature.

A rather large species commonly met with in this part of the 
Island under rotting vegetable substances somewhat dried up. It 
is very agile and ready to take to its wings which are of the beau- 
tiful typical construction, about twice the length of the body and 
in dead specimens frequently produced behind. These insects vary 
a little as to shape, some being more narrowed behind than others, 
and also as to the exact number of the abdominal segments left 
uncovered by the elytra. The head is large but exhibits nothing 
abnormal or extraordinary ; the thorax is very large, emarginated 
in front and behind, with the angles acute, the basal ones enve- 
loping the shoulders ; the wing-covers are subquadrated with 
the angles rounded off and a little narrowed behind ; the legs have 
the tibiae incrassated in the middle and the posterior coxae very 
much dilated and distant from each other, in all other respects they 
are typical. The shape of the body is that of an egg, broadest at 
the shoulders, gently narrowed towards the apex of the abdomen, 
and rounded off towards the head.
