Pennsylvania to Wisconsin, rare. The head is punctured, with a smooth spot between 
the eyes: the lateral grooves of the thorax are less deep than the medial one, and the 
sides are perfectly straight. The body beneath is bright copper-coloured, densely and 
coarsely punctured on the trunk and sternum, more finely and less densely on the abdo¬ 
men. The last ventral segment is a little more subtruncate in the female, and in both 
there is a little submarginal transverse elevated line. 
2. C. erythropus, “ viridi-a;nea, tboraee viridi-purpureo, elytris punctato-striatis, corpore subtus viridi- 
aurato, pcdibus fcrrugineis.” Long. -40.

Unknown to me: perhaps from tropical America. The characters are however so dis¬ 
tinct by the colouring, that it will be readily recognised by the above diagnosis, should it 
occur in our territory. The characters given in the description of Gory, with the excep¬ 
tion of colour, are those of the preceding species. 
GROUP III. 
While adhering very closely to the previous one by its general structure, this group is 
at the same time sufficiently marked to enable it to be readily distinguished. The chief cha¬ 
racters separating it are: the small rounded or transverse scutellum, and the sharp pointed 
prosternum, with acute lateral angles behind the coxa), as in Chrysobothris: the meso- 
sternum is separate from the metasternum, and divided by a narrow fissure in which is 
fitted the acute tip of the prosternum. The antennal pores are terminal: the mentum 
is partly membranous in one genus, entirely corneous in the other. The tarsi are slen¬ 
der, but slightly lobed, and the ungues are entire.
