CARABID^E. ANCHOMENUS. 93 



antennae pitchy. Thorax subquadrate (PI. II. f. 2), small and 

 narrowish, sides very slightly rounded and not much narrower 

 behind than in front, posterior angles rounded, disk depressed, 

 transversely wrinkled, dorsal line entire, base with two deep 

 smooth fovese. Elytra wider than the thorax, much narrower 

 than in the preceding species, oblong, shoulders rounded, the 

 sides not dilated and rounded but almost parallel, moderately 

 convex, very finely striated, with about five or six small punctures 

 between the second and third striae and also an interrupted 

 series of small foveae on the exterior margin ; legs pitchy testa- 

 ceous. Length 3 lines. 



In its general habit this insect bears some resemblance to 

 the preceding, but the elytra are narrower and more parallel 

 and uniformly pitchy brown or fuscous, without any tinge of 

 green. It cannot be confounded with pale pitchy examples of 

 fuliginosus, because its form is wholly dissimilar, the thorax 

 being considerably narrower and more quadrate, and the elytra 

 also narrower and more parallel. 



This is the Carabus piceus of Linnaeus, and is so labelled in 

 the Linnaean Collection. It is a somewhat local species, but 

 abundant in damp woods, marshes, and on river banks in various 

 parts of the kingdom.

Elongate, narrow, deep pitchy black; mouth, tip of the 

 mandibles, base of the palpi and basal joint of the antennae 

 rufous, the rest of the antennae and of the palpi pitchy. Thorax 

 oblong, widest in front, sides moderately rounded, much con- 

 tracted behind, the posterior angles very little evident, disk very 

 convex, much wrinkled transversely on each side the dorsal 

 furrow, base with a smooth impunctate oblong impression near 

 each angle. Elytra elongate, about twice the width of the 

 thorax, shoulders rounded and a little elevated, the sides rather 

 parallel or very slightly rounded till behind the middle and 

 narrowed to the extremity, disk very convex, strongly striated, 

 the striae impunctate, but some of them appearing under a 

 magnifying glass to be faintly crenulated, on the second stria 

 near the apex there is a small impression and two others on the
