 Ha. emarginatus. GyUenhal. — Ag. emarginatum. Steph. Caial. No. 130. 



Closely allied to Ag. moestum, but known by its prominent shoulders ; entirely 

 of a deep glossy black : thorax slightly strigose transversely, with a deep 

 longitudinal channel and basal fovea on each side: elytra rather conveXj 

 striated, with an impressed dot near the base of the third stria from the suture, 

 and two on the second, at equal distances between it and the apex of the 

 elytra : the humeral angle very prominent, and slightly acuminated : the 

 region of the scutellum depressed : body beneath and legs glossy black ; the 

 latter sometimes piceous. 



Not uncommon in Battersea-fields, and on the borders of Whit- 

 tlesea-mere; also near Netley, Salop.

Shorter and broader than the last; entirely deep black, or delicately glossed 

 with bluish, shining : mouth pitchy : thorax nearly transverse, the sides 

 regularly rounded, with an impressed dorsal line, and a fovea at the base on 

 each side : elytra shorter and broader than in Ag. viduum, rather convex, 

 deeply striated, the striae slightly punctate, with two large impressed dots on 

 the anterior half of the third stria from the suture, and one on the second 

 stria, midway between the last and the apex of the elytra : basal joint of an- 

 tennae pitchy. 



Found in Coombe-wood and Battersea-fields; also near Bristol, 

 and in Shropshire, not uncommonly. 



Sp. 11. afrum. Angustior, nigrum, nitidiim, thorace sublongiore, lato, elytris

 Ca. afer. Duftschmidt.—Ag. afrum. Steph. Catal. No. 132. 



Head black, glossy, smooth : thorax a little elongate, rather distant from the 

 base of the elytra, slightly convex, with a slender abbreviated longitudinal 

 line, and a fovea on each side at the base : elytra glossy-black, a little convex, 

 oblong-ovate, slightly striated, the striae impunctate ; between the second and 

 third from the suture two deep impressed dots, towards the apex, and one 

 near the base on the third : body beneath and legs entirely black. 



Known from the preceding by its more elongate form. It occurs 

 near London and Bristol, and is said to be common in Norfolk. 



f Sp. 12. Bogemanni. Nigro-piceum depressum, subtus dilutiore, ihorace breviori 

 cordato, elytris obsolete inwqualiter striatis, interstitiis subtilissime strigosis.
