as in B. parviceps and Tairuense, and not so broadly- rounded, and 

 relatively large, as in B. eustictum 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 antennas 

 and legs metallic, except the basal joint of the antennae, and sometimes 

 the tibiae, 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 striae of the elytra are very slightly impressed, but the 

 punctures are very distinct, and are not wholly obliterated near the 

 apex. 



Typical examples of B. anchonodenim are only If liu. long.

Bembidium hokitikense. 



B. anclionodei'o proxime affine ; dijfert colore nigro, thorace paulo latiori, 

 striisque 3 — 7 apice eoanescentibus. Supra paulo convexum, nigrum, leviter ceneo- 

 tmctum ; palpis, antennis, pedibusque nigris : thorace latiori, valde rotundato, juxta 

 basin constricto ibique lateribus rectis, supra vix ruguloso ; elytris punctato-striatis, 

 striis 3 — 7 ante apieem desinentibus, interstitiis paulo convexis. Lo7ig. 1^ lin. 



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

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

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

 of anclionoderum. 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 ia 

 offered by the smooth apical area of the elytra.

Distinguishable from Tr. Si/lrius and allies at once by its quite 

 different form, due to relative narrowness of the thoi'ax, which is also 

 longer, less rounded anteriorly, and more gradually narrowed to the 

 base, its basal foveae are also deeper and more curved or branched.
