black, femora, and occasionally the tibise greenish black. Length

This brilliant species varies occasionally in colour, being 

 sometimes golden green, purplish or violet, rarely obscure black. 

 It is somewhat local, but occasionally abundant. Rather plen- 

 tiful in a damp wood near Newark, Notts; Gamlingay and 

 Paxton Woods ; Coombe Wood ; Epping Forest ; Hertford, &c. 

 I have also taken it on the coast, near Ramsgate.

 parallelis, viridibus, suturd cupreo-aned, tenue punctato- 

 striatis, punctis 6 impressis ; antennis pedibusque nigris.

Head and thorax coppery with a greenish tinge, the former 

 oblong and narrowish; palpi and antennae black. Thorax 

 quadrate, short ; sides regularly and equally rounded from the 

 anterior angles to the base, lateral margins reflexed and rather 

 elevated at the hinder angles and somewhat rugose, the angles 

 scarcely rounded, disk very much wrinkled transversely, with an 

 impressed dorsal line, and two broad, deep, subpunctate fovese 

 at the base. Elytra wide, sides almost parallel, apex obliquely 

 sinuated, green, with the suture obscure coppery as far as the 

 first stria, finely striated, some of the striae at the base minutely 

 punctured, interstices flat, the third with six punctures, and the 

 outer margin with a series of deeper impressions most numerous 

 at the base ; body beneath greenish black, sides of the head 

 green and transversely strigose ; legs black. Length 4 lines. 



This insect is distinct from C. Austriacus, Fab., though it is 

 identical with Carabus Austriacus, Dufts., and Agonum Austri- 

 acum of Dejean's Catalogue. It is much more slender, the 

 thorax is smaller, narrower and shorter, not much contracted 

 behind as in that species, nor the sides so widely margined, and 

 the hinder angles are less rounded and less obtuse, in which 

 respects it accords more with the form of marginatus, while 

 Austriacus corresponds with 6-punctatus in the structure of the 

 thorax; the elytra also are narrower and more parallel, not 

 oblong-ovate as in Austriacus, and instead of a wide coppery 

 common streak at the base, have the suture alone as far as the 

 first stria dull coppery or purplish copper.
