Closely allied to B. auchonodcnim, Bates, having the same general 

 proportions — /.^., the thorax is not so short relatively to the elytra as in 

 B. parviccps and tairuense, and not so broadly rounded, and relatively 

 large, as in B. ei/stktimi, and orbiferum. The insect is also broader and 

 flatter. In nearly all the specimens the colour is dullish coppery- 

 brown, with the head more greenish-brassy, and the antennae and legs 

 metallic, except the basal joint of the antennre, and sometimes the tibise, 

 which are more or less reddish-pitchy. The thorax is slightly shagreened, 

 and, as usual in this group, rather abruptly narrowed just before the 

 base, where the sides, for a short distance, are straight and parallel. 

 The stria3 of the elytra are very slightly impressed, but the punctures 

 are very distinct, and are not wholly obliterated near the apex.

Another of the numerous ill-defined species closely allied to B. 

 anchonoderuin. The colour of the two specimens taken by Mr. Wake- 

 field is dull brassy-black, quite different from the brighter brassy tinge of 

 anchotioderiiiii. But the. chief distinction lies in the broader form of the 

 thorax, which is a conspicuous differentiating character when the two 

 species are compared side by side ; another good character is offered by 

 the smooth apical area of the elytra.

The chief characters of the genus are indicated by Mr. Bates in his 

 excellent description. Lacordaire gives no diagnosis, and regards it as 

 synonymous with Bembidium.
