34 MANDIBULATA. — COLEOPTERA. 



side in front : thorax rather broader than the head, convex, deeply punctate* 

 with a deep dorsal channel furcate anteriorly, and terminating abruptly pos- 

 teriorly ; on each side are several deep impressions : elytra broader than the 

 thorax, convex, finely punctate, each with four rows of catenulated impres- 

 sions, interrupted by smooth glossy violaceous spaces; these series are separated 

 by a slightly elevated ridge : body beneath bronzed green : thighs the same or 

 coppery : tibiae and tarsi dusky blue. 

 I first detected a third species of Elaphrus in the British cabinets, and pointed 

 out the fact to Messrs. Cooper, Curtis, and Ingpen, from my own collection, 

 which at the time contained no less than six specimens of the present species, 

 varying considerably in size and colour ; some being of a very rich metallic 

 green above, others bronzed-green, and some coppery; but all possessing 

 bluish-black tibiae, and agreeing with each other in the form of the thorax 

 and in sculpture. 



It lias been stated that this species appears peculiar to the metro- 

 politan district, but two of my specimens were taken near Swansea, 

 and one in Devonshire, in 1812; the others were captured by my- 

 self in a wet path in the hollow, beneath the " gallery," at Coombe- 

 wood, in June 1814, where the species appeared at that period to 

 be in considerable plenty. " Once taken at the root of a willow 

 near Chelsea, in September, 1824." — Mr, Ingpen. 



Sp. 2. cupreus. Cupreo-aeneus, thorace latitudine capitis, elytris maculis rotun-

El. cupreus. Megerle. — Steph. Catal. p. 42. No. 410. 



Above glossy brass, obscurely tinged with greenish : head thickly punctate, with 

 an arched impression between the eyes ; two larger beneath, and a transverse 

 frontal line : thorax above convex, punctate, with a deep anteriorly furcate 

 dorsal line, and some deep impressions on the disc, the latter not touching the 

 base, which is rather distant from the elytra, the latter above convex, of a 

 dusky-brass, thickly, but irregularly punctate, each with four rows of large 

 violaceous-green circular impressions, interrupted by polished brassy spaces, 

 those towards the suture being largest and subquadrate : body glossy greenish- 

 brass beneath : thighs greenish-brass, with the base somewhat testaceous ; the 

 tibiae pale testaceous, with the apex and tarsi blue-black : antennae greenish- 

 brass at the base, dusky at the apex. 



Differs a little in colour, being sometimes of a dusky, and at others of a brilliant 

 greenish-brass. 



Common in several places near London, especially in Battersea- 

 fields, where I have very frequently taken it, and in Copenhagen- 

 fields, at Hampstead, Hertford, &c. It also abounds near Whittle- 

 sea Mere. " Carlisle."— T. C. Heysham, Esq.
