II. Upper side entirely brouze ; antennae dark. 



i.^ 8tri;e of elytra us plain at ape.t as at base ; elytra 



parall.;l-sided P. MTTORALIS, Bit/l. 



ii. StrisB of elytra mueh weaker at apex; elytra 



slightly ovate P. chalceus, Marsh. 



P. luridipennis, Germ. {Burrellii, Curt., Fig. Brit. Eiit. i. 47). 

 Very conspicuous by its bright-green head and thorax and testaceous 

 elytra, which are sometimes slightly clouded on disc ; antennae and pal})i 

 testaceous ; thorax short, sides rounded to behind middle and thence 

 nearly straight to base, })osterior angles sharp, dorsal furrow distinct, 

 base depressed and punctured, with two broad foveas near angles bounded 

 by a longitudinal fold ; elytra rather broad^ wdth punctured striae ; 

 underside bronze-green ; legs testaceous. L. G-7 mm. 



Rare ; first discovered in England by K'ev. J. Hurrell at Salthouse on the Norfolk 

 coast in 1806; Wbilstable and Shoroliain (Clianipion) ; Slieerness (salt-marshes, 

 June, S. Stevens) ; llastinj^s ; Sandwich ; Deal ; Pegwell liay (Matthews) ; Lyniingtoa 

 Salterns; apparently it used to be very counnon in tlie Island of Sheppy, but of late 

 yeai's it appears to have become very rare in that locality. 



P. littoralis, Duft. Dark bronze, usually with a slight greenish 

 reflection ; antenme fuscous black ; thorax somewhat transverse with 

 sides considerably more dilated and rounded in front than in the pre- 

 ceding species, slightly narrowed behind, posterior angles distinct but 

 not projecting, dorsal furrow^ distinct, abbreviated in front, base de- 

 pressed and strongly and rugosely })unctured, basal fovese deep, rugose, 

 l)ounded by a longitudinal fold ; elytra rather broad, parallel-sided, striae 

 ))unctured, strong and well defined to the extreme apex, the punctures 

 however ceasing behind middle ; legs ferruginous, femora dark. L. 

 6|-7s nim. 



Local but not uncommon ; Whitstablc, Gravesend, Sheerness, Chatham, Deal, 

 Hastiny^s; Marirate ; Portland; Isle of Wiijht ; Lymington Salterns; North Devon; 

 apparently confined to the more southern portions of England. 



P. chalceus, ^larsh, IJronzo, or brassy, sometimes bluish or 

 greenish, or almost black, shining; smaller than the preceding, and dis- 

 tinguished from it by having the striae of the elytra distinctly feebler 

 towards apex, and by the fact that the sides are more rounded ; the 

 sides of the thorax are less dilated in front, whicli give it the appearance 

 of being somewhat longer, and the posterior angles are .slightly sharper : 

 in other respects the two species are very similar, but there can be no 

 question as to their being distinct. L. 6 mm. 



Common and widely distributed along the coasts of England towards the south, 

 but much rarer towards the north. I liave never taken a specimen on the Lincoln- 

 shire or Yorkshire coast, and only one locality is recorded from Northumberland; 

 Scotland very local. Forth, Tay, Sohvay ; Ireland, Baldoyle and Portrayne, Dublin. 



TRUNCATIPENNES. 



The Trunratipenne series contains a largo nundier of exotic forms, of 

 which, if we except perhajis the Dromius group, only comparatively few
