Xieng Khouang (April). 
I have seen only a single male of this species, the smallest 
yet known of its genus. It is of a peculiarly compact 
oblong form, with a strongly transverse prothorax, whose 
. greatest width is equal to that of the elytra, and narrowing 
very little to the shoulders. It is very smooth and shining, 
with a deep basal furrow, no longitudinal channel, and 
basal fovee strongly impressed and extending almost to the 
middle. The elytra scarcely taper behind, and are closely 
and evenly punctured, but smootb and shining. The legs 
and antennz are short and stout, the third joint of the 
latter conical in shape and little longer than it is broad at 
the outer end, the succeeding joints all transverse. 
The tibiz of the male are not toothed, but broadly dilated 
a little beyond the base and clothed with close silky pubes- 
cence towards the extremity. The hind tibiz are especially 
broad from the middle (where they are strongly curved) to 
the extremity. The middle tibiw are incurved just before 
the end. 
Eumorphus austerus, Gerst. Nam Tiene, Upper Mekong. 
This species ranges from Assam to Cambodia. 
Eumorphus sanguinipes, Guér. This was found by M. Vi- 
talis in the same locality as the last, and has a similar range 
northwards, but I have not seen it from farther south.
