HARPALID^'.. — PTEROSTICHUS. 123 



" Occasionally taken near Bagley-wood, Oxfordshire." — Rev. F. 

 W. Hope. " Near Windsor; and in a salt marsh near the Lary." 

 — Dr. Leach. 



Sp. 6. octopunctatus. Plate VII. f. 4. — Alatus, nigro-aeneus, nitidus, tibiis 

 tarsisque rufescentibus, elytris striatis punctis quatuor impressis. (Long. corp. 

 51 lin.) 



Ca. octopunctatus. Marsham. — Pt. octopunctatus. Steph. Catal. p. 25. No. 207. 



Deep greenish bronze, shining : head porrect, with two rather obsolete impres- 

 sions on the nasus: thorax rather narrow, somewhat convex, the dorsal channel 

 not very deep, with a slightly punctate fovea at each posterior angle : elytra 

 seneous, rather convex, broader than the thorax, simply striated, with about 

 four rather deep impressions on each elytron between the second and third 

 stria, and an interrupted marginal series, the margin itself reddish : legs dusky 

 black : tibiae, tarsi, and palpi reddish. 



Probably a strong variety of the preceding, diflfering in being rather more slender, 

 and in having fewer impressions on the disc of the elytra, but decidedly not 

 the Pt. parumpunctatus of De Jean, of which the characters are noticed in 

 page 121, from Germar, who has given a full description of that insect in his 

 " Nova Species Insectorum," &c., vol. i. p. 19, and tells us that it inhabits 

 France and "Western Germany ; neither is it the Ca. octopunctatus of Fabricius, 

 which according to him is a native of America ; I have, however, retained 

 the name, as the Fabrician insect is apparently referable to another genus. 



I have seen but three specimens of this species : one in the col- 

 lection at the British Museum, a second in that of Mr. Vigors, and 

 the third in my own ; with their localities I am unacquainted. 



Sp. 7. macer. Plate VII. f. 5, — Alatus, nigro-piceus, nitidus, thorace postice 



utrinqve unistriato, elytris striatis, pedibus rufis. (Long. corp. 5^ — 6J lin.) 

 Ca. macer. Marsham. — Pt. macer. Steph. Catal. p. 25. JVo. 208. 



Deep glossy pitchy-black or ferruginous : head smooth, with a rugose impression 

 on each side of the forehead : thorax much narrowed behind, vnth a strong 

 dorsal line, and a deep oblong impression at the base near the posterior angles, 

 which are a little punctate : elytra flat, simply striated, with three remote im- 

 pressions on the disc between the second and third striae, and a few on the 

 margin, approximating at the base : thorax punctate beneath : legs and palpi 

 rufous : antennae dusky at the tip. 



Var. )S. Larger and of a deeper colour : the thorax rugose. 



This and the two preceding insects differ from the other Pterostichi by having 

 the terminal joint of the external maxillary palpi rather shorter than the third, 

 and by possessing ample wings; by these characters approaching to the genus 

 Platysma. 



Copenhagen-fields ; abundant in Hackney-marshes, and near 

 Southend ; under the bark and roots of trees, beneath stones, &c..
