This genus, established by Professor Bonelli, embraces near 
40 species from every quarter of the globe, presenting consi- 
derable variety of outline in the thorax, which will afford very 
good characters for several subgenera or divisions : In con- 
firmation of this assertion it is only necessary to refer to the 
figures in the plate, the thorax of C. sulci colli s being triangu- 
lar, truncated anteriorly, whilst that of C. nigricornis (fig. 9) 
is nearly quadrate ; and in C. vestitus the difference is even 
greater, the thorax being slightly narrowed behind. 
Chlcenius sulcicollis is figured in the 125th plate of Sturm’s 
beautiful Insects of Germany (Deutschlands Fauna), which 
enabled me to identify our insect, which had stood in the ca- 
binet many years without a name. It appears to be very rare 
upon the Continent, where it is found under stones in moist 
situations. I am indebted to my brother for the female de- 
scribed, which is the only British specimen known ; he found 
it dead under the cliffs at Covehithe, Suffolk, where I have 
frequently sought for it since without success. 
There are 3 other species inhabitants of this country which 
our insect will follow ; viz. 
1. C. vestitus Fab., Panz. 31. 5. — found as early as March 
on moist banks and in woods. 
2. C. nigricornis Fab. — found upon moist banks and in 
marshes in April. 
3. C. holosericeus Fab., Panz. 11 . 9. — very rare, taken by 
the Rev. T. Skrimshire in Norfolk in the spring. 
Like most of the Carabidce they are vernal insects : many 
of the exotic species are very beautiful ; green is a prevailing 
colour amongst them, and they frequently have a margin of 
yellow or ochre-colour round their elytra. 
The plant figured, Bunias Cakile (Sea Rocket), was ga- 
thered in the neighbourhood where the insect was found.
