94 CARABID^l. ANCHOMENUS. 



third before the middle, the exterior margin being also furnished 

 with the usual series of fovese; legs pitchy red. Length 3^ 

 lines. 



This species may immediately be distinguished from any of 

 the preceding by its more elongate narrow form, in which respect 

 it resembles Thoreyi, but independently of its dark colour it is 

 rather larger, more convex, the elytra are more deeply striated, 

 and the sides less parallel than in that insect. It is the true 

 Carabus pelidnus of Paykull, and perfectly distinct from Ag. pe- 

 lidnum, Steph., which corresponds with the next species. In the 

 Stephensian cabinet it stands under the name Ag. affine, Steph. 



It is apparently one of our rarest species, and I have met 

 with but two indigenous examples ; the one in the Stephensian 

 cabinet above mentioned, captured near London ; and the other 

 in my own, for which I am indebted to Mr. F. Bates, of 

 Leicester, who procured it from under a heap of "vegetable 

 matter (principally Ranunculus aquaticus), raked out of Groby 

 Pool, near Leicester, in June or July." 



20. A. Thoreyi : capite thoraceque nigro-piceis, hoc oblongo- 

 ovato, postice coarctato, angulis posticis subrotundatis ; 

 elytris rufescentibus, elongatis, subparallelis, subtiliter 

 striatis, punctis tribus vel quatuor impressis ; antennis 

 basi pedibusque rufescentibus.

Head black or pitchy black, smooth and convex ; mouth, 

 palpi and basal joint of the antennse pitchy red, rest of the 

 antennae obscure. Thorax pitchy black with the margins often 

 narrowly rufous, sometimes the disk pitchy rufous with the 

 margins paler, oblong-ovate, narrow, sides a little rounded, con- 

 tracted behind, posterior margins rounded so that the hinder 

 angles are very slightly evident, disk very convex, having 

 numerous transverse wrinkles on each side the dorsal furrow 

 and a very slight stria near each hinder angle. Elytra rufescent, 

 with an obscure dash in the middle next the suture, elongate, 

 narrow, about twice the width of the thorax, shoulders rounded, 

 sides very nearly straight, disk very moderately convex, finely 

 striated, the third stria with two punctures and the second with 

 one or two placed as in the preceding species ; body beneath 

 pitchy, with the thorax occasionally rufescent in less mature 

 individuals ; legs red with the joints pitchy. Length 3 lines. 



This insect nearly resembles pelidnus, but it has always rufes- 

 cent elytra ; it is also smaller ; the elytra are less convex, more
