1890.] E. T. Atkiuson — Catalogue of the Carabidm. 
III. Motasternum prolonged behind in a triangular process, the ante- 
coxal piece entirely wanting : habits aquatic. 
Antennae slender, filiform or setaceous, abdomen with six seg- 
ments : eyes two : Dytiscida. 
Antennse irregular, very short : abdomen with seven segments 
of which the first two are closely united : eyos four : Gyrinidce. 
The Carahidce are divided into three sub-families : — 
Middle coxal cavities not entirely enclosed by the sterna, the epimeron 
of the mesosternum attaining the cox® : Carabince. 
Middle coxal cavities entirely enclosed by the sterna, the epimeron of 
the mesosternum not attaining the coxae. 
Head without antennal grooves beneath and with distinct super-orbital 
Betas : ambulatorial set® of abdomen usually well developed. Harpalince. 
Head with distinct, usually long, antennal grooves beneath, and with - 
out distinct super-orbital setae : ambulatorial set® of the abdomen 
feeble or wantiug. Pseudomorphinas. 
The Harpalinae are further subdivided into two sections, the first in 
which the head has two super-orbital setigerous punctures, the second in 
which there is but oue. The groups included in the subfamilies are as 
follows : —

Several of these groups are further subdivided, but these details need 
not be noticed here. 
M. Borrd writes of this arrangement : — ‘ Beaucoup des genres prennent 
ainsi des places bien differentes de celles oil nous sommes accoutumes da 
les voir ; deja, dans l’arraugement des tribus, nous avons pu voir que des 
afiinitda cousacries par un usage pour ainsi dire goneral, sont tout a 
fait brisSes, etje dois dire avec justice, car tous ceux qui out approfondi 
un peu la matiere le savent, il n’y avait dans notre classification que trop 
de traces de cette mesquine 6tudo que l’on peut l’appeler l’entomologie
