Dr. Arzevius’s Objervations on the Genus Paufus. 247. 
Both thefe fpecies } have carefully compared, and found to 
agree in many circumftances; but I fhall here only mention the 
moft ftriking ones, as well as thofe which ftand in need of fome 
explanation, or where, from want of proper termini technici, I fhall 
be under the neceflity of ufing circumlocution in order to be under- 
ftood. 
The Body is hairlefs, fmooth, and polifhed, above fomewhat de- 
preffed, before narrower, and behind nearly cylindrical ; the fixe 
{mall, being from the top of the antennz to the end of the abdo- 
men only three lines long, and acrofs the elytra not quite one broad; 
the colour uniform, a darker or lighter brown ; the motion fteady and 
flow, at leaft in the {pecies I have feen alive. It is very unlike all 
other genera I know ; but it feems to come neareft to the Clerus of 
Fabricius, bearing to it, at leaft upon the whole, fo much natural 
refemblance that its moft proper place in the fyftematical arrange-- 
ment will be next after that genus. 
’ The Head is {maller and thorter than the thorax, almoft round, 
and at the bafe furrounded as it were by an annular fegment; inthe 
living animal it is pointing ftraight forward, but when dead it com- 
monly bends a little downwards. The c/ypeus is minute, and more 
or lefs depreffed in the middle. On the throat there is a convex 
fpot, raifed in form of a triangle, which is nearly equilateral, the 
bafe of which forms a crofs-bar between the eyes, its two upper 
angles being acute, but the lowermoft cut off by the annular feg- 
ment juft mentioned. 
The Eyes are rather large, tranfverfally oblong, prominent, and 
fituated in a focket, the brim of which is elongated into one angle 
before lying horizontally, and another behind ftanding upright; 
which ftructure feems to prevent the infeét from being able to look 
in any other direction than forwards,
