Head black : palpi blackish-piceous : antennae 

 brown towards the tip: thorax entirely black;

 base very slightly wider than any other part; 

 lateral edge nearly rectilinear, very slightly in- 

 curved before, and not at all excurved near the

OBSERVATIONS. 



This species is an inhabitant of Pennsylvania, 

 and may be occasionally found under stones and 

 other objects, which rest loosely on the soil. Its 

 colour is a uniform black, without any tint of 

 those gay colours for which the two preceding 

 species are remarkable.
