Rh 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 description. 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. The 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 oblique 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 Dyschirius, 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 Clivancæs, I have hitherto not discovered a single Dyschirius, a genus so well
