ABDOMEN in specimine nostro mutilatum. 
At first sight the little insect exhibiting these characters might 
be mistaken for a species of Notiophilus of Duméril, or at least 
be regarded as belonging to a cognate genus. Its large and very 
prominent eyes, the shape in some measure of its thorax, the 
striæ of the disk of its elytra less impressed with puncta than 
those of the limb, as likewise its frontal furrows, give it no in- 
considerable appearance of aflinity to it. But a closer inspec- 
tion proves that this is merely an appearance, and that in fact 
it belongs to a different tribe connected with the Harpalide. 
Notiophilus and its genuine affinities are distinguished by a par- 
ticular character indicating some difference in their mode of 
taking or retaining their prey. ‘The great majority of the Ca- 
rabi of Linné are remarkable for a notch on the inner side of 
their anterior tibiæ, armed at its upper angle by a spur, which 
appears to be of use to them for the above purpose. In the 
Harpalide and many others this notch is nearly in the middle of 
the tibia; but in Notiophilus and its affinities its situation is close 
to its apext. Catascopus, with respect to this part, falls into the 
former tribe}. Again, in Notiophilus the labium consists only of 
a single lobe, or at least the lateral ones are much shorter than 
the central$; but in the Harpalide they are as long or longer |. 
In Catascopus also they are very conspicuous, being twice the 
length of the central lobe. In Elaphrus, Notiophilus, Blethi-
