HARPALIDiE. POGONUS. 107 



An elegant species, discovered by the late Rev. J. Burrell near 

 Salthouse, on the Norfolk coast, which, so far as I am acquainted, 

 is its only locality in Britain, 



Sp. 2. chalceus. Plate VI. f. 5. — Viridi ant cupreo-oeneiis, pedibus ryfescen- 



tibus, antennis hasifuscis. (Long. corp. 2^ — 3^ lin.) 

 Ca. chalceus. Marsham. — Po. chalceus. Steph. Catal. p. 22. No. 175. 



Glossy feneous : head smooth, with a deep stria on each side between the eyes : 

 mandibles dusky-red: thorax slightly convex, the base punctated, with a 

 fovea at the hinder angle on each side, and an impressed line : elytra coppery, 

 varying much in colour, from tinges of green, brassy, black, and dusky to 

 bluish ; punctate-striated, the lateral strise rather obsolete, the interstices flat, 

 with three impressions on the third from the suture : body beneath black, 

 tinged with seneous : palpi rufescent, with the terminal joints dusky : legs 

 rufescent : antennae dusky or fuscous, with the tip reddish. 



Var. p>. With the antennae and legs ferruginous : the body narrower than usual. 



Var. y. Antennae riifescent : legs dusky. 



Var. S. Very short and broad, of a blue-brass, with the margins of the elytra 

 and legs bright ferruginous ; probably distinct ; I formerly called it by the 

 name of Po. brevis, in allusion to its abbreviated form. 



This insect varies greatly in form and colour, and were it not from the circum- 

 stance of most of the specimens in my collection having been captured at the 

 same time, beneath the same heaps of rejectamenta, I shoidd be disposed to 

 consider several of them as distinct species. 



Inhabits the eastern coasts of Britain, and found not uncommonly 

 on the shores of the Thames and Medway ; it also occurs in com- 

 pany with the former species, and likewise on the coast of Gla- 

 morganshire. 



Sp. 3. seruginosus. Plate VI. f. 6. — Oblongus, viridi-ceneus, antennarum apice 



pedibusque rufescentibus. (Long. corp. S^ lin.) 

 Po. seruginosus mihi. — Steph. Catal. p. 22. JVo. 177. 



Allied to the last, but considerably more oblong, and narrower, especially the 

 thorax, with the head more porrect ; it is of a bright brassy-green above : 

 head smooth, with a slight impression on each side: mandibles dusky: 

 antennae greenish-bronze at the base : thorax as in the last, but the base very 

 thicldy punctate : elytra deeply punctate-striated on the back, but obsoletely 

 so at the apex and sides, the latter with a row of remote impressed dots; the 

 tip of the elytra and the legs rufescent : the body beneath very smooth glossy 

 brassy -black. 



This species (of which six specimens only have come under my 

 inspection) was discovered about ten years since by a very active 

 collector, Mr. D. Bydder, on the Hampshire coast, near Christ- 

 church, and I am unacquainted with any other locality; bright
