Fig. 19. FERONIA (LYPERUS) ATERRIMUS, Payk. \F. Feroniidje. G. Feronia, 

 Latr. s-G. Lypcrus, Chaudoirl] (Omaseus atcrrimus, Curtis.) 



Deep sHning black. Head much narrower than the thorax ; smooth, with two deep curved 



impressious between the antennas. Thorax sub-quadrate, scarcely narrowed behind, slightly 

 rounded at the sides, its lateral margins reflexed, posterior angles rounded, disk convex, a deep 

 finely rugulose fovea on each side at the base. Elytra a trifle wider than the thorax, elongate, 

 finely punctate- striate ; interstices flat, smooth, the third with three large impressions, the anterior 

 of which is contiguous to the third stria, the two posterior to the second stria. Length, 6.^-7 lines. 

 Formerly abundant at Whittlesea Mere, and in the fens of Cambridgeshire and Norfolk. 



Fig. 20. FERONIA (PTEROSTICHUS) ELONGATUS, Curtis. [F. Feroniidfe. G. 

 Feroniaj Lff/r. s-G. Pterostichus, iJowe//i.] (Pterostichuspyrenseus? rfeC^awf^ozV.) 



Narrow, elongate, shining black. Head large, nearly as wide as the thorax ; antennas, 

 brownish, the three basal joints black. Thorax broader than long, narrowed behind, posterior 

 angles acute, with a consjiicuous central longitudinal channel, and an elongate fovea on each side 

 at the base. Elytra scarcely wider than the thorax, elongate, their sides par.illel, sinuate- 

 truncate at the apex ; the sutural angle acute ; finely striate, the stria; minutely, remotely, and 

 obscurely punctate ; interstices flat, smooth, the third with five large impi-essed points, of which 

 the anterior is contiguous to the third, the four posterior to the second stria. Length, 7' lines. 



Nearly allied to Feronia (Pterostichus) Lasserei, Fairm., but readily distinguished by its 

 narrower form, and its elongate, depressed, parallel, sub-truncate elytra. 



Introduced into the British list upon the authority of an example, extant in the British 

 Museum, supposed to have been taken, many years ago, in Devonshire, by Dr. Leach. 



Fig. 21. POGONUS LURIDIPENNIS, Germar. [F. Feroniidse. G. Pogonus, Dejean.'] 

 (P. BurrcUii, Curtis.) 



Head and thorax bright green, with a brassy or coppery tint ; palpi, antennse, legs, and 

 elytra, pale yellow ; the latter occasionally with a dark, ill-defined patch on the disk. Head 

 conspicuously narrower than the thorax ; smooth behind ; finely chagrined anteriorly and at the 

 sides, witli two broad longitudinal impressions between the eyes. Thorax much broader than 

 long, rounded at the sides, narrowed behind ; the base depressed and ruggedly j)unctate ; posterior 

 angles nearly rectangular ; foveas shallow, bounded externally by a little ridge ; disk convex 

 transversely wrinkled, dorsal channel distinct. Elytra elongate-ovate, finely punctate-striate ; 

 interstices flat, the third with three impressions, the two anterior contiguous to the third stria, 

 the")wsterior to the second stria. Underside brassy green. Length, 3i-3| lines. 



First discovered in Britain near Salthoixse on the coast of Norfolk. Taken, also, near 

 Lymington ; and abundantly near Sheeruess, on the muddy margins of pools of salt water. 



Fig. 22. DYSCHIRIUS NITIDUS, Dejean. [F. Scaritidfe. G. Dyschirius, Fabricius.'] 

 (D. iriermis, Curtis.) 



Brassy black, with a slight bluish or greenish tint. Head usually smooth, bi-dentate in front, 

 forehead with a deep transverse impressed line, which is sometimes interru]ited in the middle, a 

 deep furrow on each side, the space intervening between it and the eye forming an elevated ridge, 

 a broad, shallow depression in the centre, and one or two indistinct transverse strias behind ; man- 

 dibles, palpi, and base of antenna;, pitchy red. Thorax ovate, convex, longer than broad, its 

 greatest width a little behind the middle, with an arcuate impi-essed line in front, the space en- 

 closed between it and the anterior margin with fine closely set longitudinal stri», central 

 longitudinal channel deep. Elytra oblong ovate, sub-truncate at the base, shoulders moderately 

 rounded, with eight dorsal stria;, the first and second uniting at the base in a deep round im- 

 pression, the strias of equal depth from base to apex, but becoming gradually shallower towards 

 the sides, distinctly punctured at the base, interstices smooth, the third with two or three large 

 punctures contiguous to the third stria. Legs reddish-brown ; of the anterior the thighs robust, 

 black, the tibiaj wide, their external margin unarmed. Length, 2-21 lines. 



Preston Marsh, and Lytham, Lancashire ; and, it is said, near Yarmouth.
