Although the representatives of our indigenous genera of 
Scaritini, Clivina and Dyschirius, abound everywhere, our know- 
ledge of their natural history seems still open to not unimpor- 
tant additions. On a previous occasion* I drew attention to 
several peculiarities in the structure of the mouth not hitherto 
noticed—for instance, the convenient character for distinction be- 
tween these two genera, that the anterior margin of the clypeus 
is merely slightly emarginate in Clivina, but bi- or tridentate 
in Dyschirius; and in a paper on the new genera Niletus and 
Ochyropus +, I have pointed out that both Néletus and Clivina, 
_ Dyschirius, Oxygnathus, and Oxystomus amongst Scaritini, pos- 
sess a sharp, hard, horny spine between the claws—a true ony- 
chium, the possession of which was formerly looked upon as a 
principal character of certain Lamellicornia, but which really 
occurs in many Coleoptera. ‘T'o these we shall add two other 
remarks. The inner lobe of the maxille in Dyschirius is 
almost straight, and truncate at the apex, though it is often de- 
scribed as pointed, owing to some of the terminal spines being 
mistaken for the apex of the lobe. But in Clivina (fossor) the 
lobe terminates, as in other Carabi, with an inwardly bent hook. 
In Dyschirius the two bristles of the lingua are divergent, whilst 
in Clivina (fossor) they stand so close together as to look like 
one thick bristle. The anterior margin of the palpifer is 
rounded in Dyschirius, with finely serrated edge, whilst in Cli- 
vina it presents an obtuse angle with undulated edge. 
In examining the organs of the mouth in a great number of 
specimens of Dyschirius, I observed that in many individuals
