 three joints at tlie hase of the antennte testaceous, wliereas A. lunicuUis 

 has hut two. L. 1-1\ m\\\. 



Apparcutly mixed in collections with the preceding, and not uncommon. 



(Sub-Gen. Triaena, Leconte.) 



T. Base of thorax impunctate ; striae of elytra plainly punc- 

 tured; lenfjth Smin A. STEE>'rA, Zimm.

 punctured; length 6 nnu A. PIEBEIA, Gyll. 



A. strenua, Zimm. Jirassy, greenish, hhiish, or bluish-black, 

 thorax and elyti-a not always concolorous ; antenna; with the first three 

 jdints and biise of the fourth red; thorax with sides moderately con- 

 tracted in front, anterior angles scarcely prominent, posterior angles 

 sharp, dorsal fun-ow ending in a longitudinally striated shallow depression 

 in front and behind, base impunctate, with two fovece on each side, 

 the outer one more or less obsolete ; elytra rather long, plainly striated ; 

 the striie are distinctly punctured until they become deeper at apex, 

 when tlie punctures cease ; femora pitchy black, tibiae and tarsi ferru- 

 ginous : the anterior tibiae have the spine at the apex tricuspid, which is 

 the chief distinguishing character of this and the next species. L. 8 mm. 



Common in early spring in the salt marshes near Ryde, Isle of Wight : Dawson 

 (Knt. Ann. 1858, 53) recorded it from the Isle of Sheppy, but this may have been in 

 error, as it has not occun-ed there since, and no other authentic locality is known 

 except the Isle of Wight. 



A plebeia, Gyll. Very shiny, brassy or greenish, antenna} with 

 first tliri>c joints and base of fourth red ; thorax rather more emarginate 

 in front than in tlie preceding species, so that the anterior angles are 

 more strongly produced, sides gradually rounded from apex to middle, 

 tluince straiglit to base, posterior angles sharp produced oAving to the 

 basal margin l)eing sinuate, dorsal furrow more distinct in middle, bjise 

 with two shallow but usually distinct, coarsely punctiu'ed foveas on each 

 side ; elytra distinctly striated, the striie impunctate or very obsoletely 

 punctured ; femora and tarsi pitchy-black, tibia; testaceous : the spine at 

 the apex of the anterior tibiaj is tricuspid. L. G mm. 



Common and widely distributed throughout England; Scotland, cwnmon as far 

 north as the Moray district ; Ireland, local near Dublin. 



ANCHOMENINA. 



The members of this tribe ma> l,)e separated from the Fterostichina 

 and Amarina by the fact that the subapical margins of the elytra arc 

 continuous, whereas in the two la-st-montioned tribes they are interni])ted, 

 the severed apical portion of the margin continuing as a sharj) ridgo 

 along the under surface of the elytra : it is true, a? Mr. Uates says 

 (lUul. Cent. Amer. Carabidrc, p. 91), that there are indications of the
