This as well as the following specie? belongs to Erichson's divi- 
sion II. B. of the g.j both having the abdomen immarginate and 
the 4th tarsal joint bilobed. Everything about this species is 
elongated. The head is about one-third broader than the thorax, 
the forehead is slightly excavated with 2 elevated ridges running 
from the root of the antennae a short distance upwards, a third runs 
from the crown of the head down towards the centre of the two 
former,but all three reach only to about the middle of the head. The 
part below the antennee is covered with white hair« The antennae 
have the 3rd joint much elongated and the terminal club composed 
of elliptic joints. The thorax is rather slender, incrassated at the 
middle, gradually narrowed in front but nearly quadratic behind. 
The elytra are longer than the thorax, about double its breadth and 
oval being slightly narrowed at the shoulders and the apex. The 
legs are long and slender, hairy at the apex of the tibiae and the 
tarsi, the latter very much so on the inner side. The insect is of 
a metallic black color highly polished, the legs, palpi and the first 
2 antennal joints are whitish, the tibiae and the apex of the palpi 
being, however, rather darker, joints 3-11 of the antennae are 
brownish, the coxae and the mouth are yellowish, the tarsi have a 
brown spot at the apex of the first 3 joints, the claws are black. 
The insect is punctured all over, but less so on the abdomen, the 
apical segments of which are indeed nearly smooth, and sparingly 
covered with small white hairs.
