is at once recognised by its depressed and, in proportion to its 
width, very long shape. The labrum, antennae and legs are so 
much like those of the former that they need no further descrip- 
tion. The bristle of the ligula appears simple.

As distinguished as the preceding two species. The palpi and 
the mentum appear to me of a somewhat extraordinary form. I'he 
last joint of the former is considerably more inflated at the 
base than in any other Ceylon species that has hitherto come under 
my notice, whilst the others are of a -very curved appearance in 
both the maxillary and labial palpi. The emargination of the 
mentum would at first sight appear to be of a semi-lunar shape. 
However, it is only the lower margin which has this form, the ob- 
lique truncature which forms the emargination being such as to 
give it that shape. The tooth is of the typical shape, but being 
on a level with the lower margin, it stands at a small angle with 
respect to the inclined plain formed by the rest of the truncature. 
The apical angles of the lobes are somewhat pyramidal being formed 
by 3 sides. I have not dissected the labium, therefore do not know 
whether the remaining parts exhibit any peculiarities. The insect is 
however, easily distinguished by its general facies, which is rather 
like that of a DyschiriuSy from which genus, however, the mentum 
alone is sufficient to separate it. I may as well remark here that, 
although the Island is well supplied with Scarites and ClivancEs, I 
have hitherto not discovered a single Dyschirius, a genus so well
