HARPALID^. — AGONUM. 93 



Allied to the preceding but discriminated by its uniform colour abovej and by 

 the deep impressed line near each basal angle of the thorax, the last species 

 being usually destitute of any impression on that part : the entire insect is of 

 a deep metallic black, with the exception of the antennae and legs, which are 

 of a pale ochraceous-pitchy hue : the disc of the thorax is convex, and the 

 elytra are rather sHghtly striated, with an obsolete interrupted marginal series 

 of dots, which become stronger towards the tip. 



This, which is probably the Ag. pelidnum of Sturm, seems rare, 

 as I have hitherto seen one specimen only, which I caught near 

 London. 



Sp. 28. pusUlmn. Atrum nitidum, thorace breviore, postice utrinque Jbvea im- 

 presso, elytris striatis, strid marginalis obsolete punctatd. (Long. corp. 2| lin.) 

 Ag. pusiUum mihi. — Steph. Catal. p. 19. JVo. 149. 



The smallest indigenous species of the genus : the entire body, with the legs, 

 antennae, mouth, and palpi, is of a deep black, obsoletely tinted with violet : 

 the thorax approaches in form to that of the insects of the first division, being 

 short, and apparently more orbicular than oblong; it has some obsolete trans- 

 verse wrinkles and an impunctate fovea on each side near the basal angles : 

 the elytra are simply striated, the margin having a very obsolete series of 

 impressed dots. 



The smallest species of the genus, and very distinct from all. It 

 might probably arrange more advantageously near Ag. consimile 

 and its congeners : one specimen only has been seen by me, which 

 was taken near London. 



Sp. 29. livens. Oblongum, depressum, nigrum, ore antennis pedibusque rufo- 

 ferrugineis, elytris striatis, fronte rufo-bimaculatd. (Long. corp. 3^ — 4 Un.) 

 Ha. hvens. Gyllenkal. — Ag. Uvens. Steph. Catal. p. 19. No. 150. 



Head smooth, glossy black," with two ferruginous spots between the eyes: 

 mouth pitchy-red : palpi reddish : antennae ferruginous, the second, third, 

 and fourth joints pitchy at the base: thorax glossy shining black, cordate, 

 the disc sub-convex, channelled, slightly strigose, the margin smooth, with a 

 deep, elongate, punctulated impression at the base on each side : scutellum 

 smooth, black: elytra oblong, above depressed, black, shining, slightly 

 striated, the strise and interstices impunctate, the margin with a nearly con- 

 tinuous series of impressions, which approximate towards the apex : body 

 beneath smooth, pitchy-black, with the apex testaceous : legs totally rusty-red. 



Apparently a maritime species. It has been captured at Bognor 

 and Hastings ; and I have an immature specimen, which was found 

 in the vicinity of Brighton : it has also been taken in Norfolk.
