18 MANDIBULATA, — COLEOPTERA. 



The largest of the genus : head and thorax of a bright coppery-green or brassy- 

 black, the former smooth, with the usual sulci rather obsolete, the ophthalmic 

 fold very distinct : thorax slightly convex, with a moderate dorsal line ; the 

 base impunctate, with a deep fovea on each side, margined with a longitudinal 

 carina, as in Argutor : elytra brassy-brown, punctate-striated, with a trans- 

 verse pale waved fascia towards the apex, and two deep impressed dots between 

 the second and third striae from the suture : body beneath greenish, or brassy- 

 black, shining: legs and basal joint of the antennae brown, the rest of the 

 latter and the palpi dusky, sometimes a little tinged with piceous. 



Not very common : it is, however, occasionally taken in damp 

 places near London, but is far more abundant in South Wales, 

 occurring near Swansea and Milford. " Earl's-court, Old Bromp- 

 ton, rather plentifully." — Mr. Waterliouse. " Walham-green " — 

 Mr. Westwood. " Netley, Salop." — Rev. F. W. Hope.

Much less than the last: head and thorax of a green or bronzed copper, the 

 former minutely punctulated, with two rather shallow frontal sulci ; the latter 

 with a deep dorsal line, and a deep large fovea on each side at the base : 

 elytra of a livid hue, glossed with aeneous, with various irregular brown 

 streaks and patches, leaving a waved paler band towards the apex ; they are 

 rather faintly striated, the striae punctate and brown ; the disc with two im- 

 pressed dots : the body beneath pitchy-black or brassy : the legs testaceous 

 brown; the basal joint of the antennae the same; the others pitchy or dusky. 



Sometimes met with in the metropolitan district, though not in 

 company with the last, but infinitely more abundant near Swansea. 

 " Netley, Salop ; Isle of Siieppey, Sandown, and Deal, in June 

 last." — Rev. F. W. Hope. 6i Banks of ponds, Battersea, and Copen-
