thorax narrower, and less transverse, and having an ob- 
solete, but always more or less distinct, central longitu- 
dinal channel, the hind-body less pointed at the extremity, 
and the thorax and elytra not quite so finely punctured. 
The antenne are pitchy in colour, with the basal joint 
yellowish, and the next pitchy-yellow; they are thickened 
towards the apex, the third joint is distinctly shorter 
than the second, the fourth joint is smaller than the 
others, and about as long as broad, joimts 6-10 are 
slightly transverse. The head is blackish, about half as 
broad as the elytra; the thorax is about half as broad 
again as it is Jong; it is convex transversely, but not 
longitudinally, it has an indistinct central longitudinal 
channel, and is densely and finely punctured and pubes- 
cent (owing to the channel, this pubescence has the 
appearance of being combed or parted on each side). 
The elytra are rather lighter in colour than the head and 
thorax, are about one-third longer than the latter, and 
are densely and finely punctured. The hind-body, 
though distinctly narrowed to the apex, is not very 
pointed, it is throughout very finely and very densely 
punctured, the extremity, and sometimes the hind mar- 
gins, of the segments, being ferruginous. The legs are 
yellow. Distributed throughout England and Scotland, 
but rather rare. 
The next species is very different from any other I am 
acquainted with.

The antennee are pitchy in colour, sometimes a little 
paler at the base, they are but slightly thickened to- 
wards the apex, third joint slightly shorter than the second, 
fourth a httle smaller than the fifth, 6-10 slightly trans- 
verse, eleventh joint scarcely so long as the two preceding 
together. The head is pitchy, or pitchy-black, more than 
half as broad as the elytra, closely and finely punctured, 
rather shining; the palpi are yellowish. The thorax is as
