254 Dr. Arzexius’s Obfervations on the Genus Paufis, 
hairs. The ¢arfi are nearly cylindraceous and very flender, com- 
pofed of four joints, three of which are of equal length, but the outer- 
moft longer, all marked at their tops with a hair on each fide, and 
otherwife hardly diftinguifhable. At thesend of the tarfi there/are 
two longifh claws, crooked inwards, and diverging. 
From this generic defcription it is very eafy to be convinced that 
Paufus never can be of the fame genus as Cerocoma. And it is 
rather a matter of furprize that Fabricius, who always has been 
ready to divide the genera of Linné, and fometimes has done it for 
reafons, I fear, not very urgent, fhould now unite two fo ftrikingly 
and effentially diftinct. He fays, it is true, ‘‘ that he has only put 
it in here for future examination, that it feems to be a genus of it- 
felf, and that he does not know it rightly.” But then it might 
perhaps have been as-well not to have mentioned it at all. Be this 
however as it may, in order to prevent any farther mifconception on 
the fubjeét, I will here ftate all.the principal circumftances by 
which Cerocoma differs from Pau/fus. 
The Body is of an oblong fhape, and almoft of an equal breadth 
throughout, the head and the thorax being {carcely narrower than the 
elytra. It is found without the tropics in the South of Europe and 
the moft Northern parts of Africa, on plants growing in open fields. 
The Head is oval, and inflected downwards. 
The Antenne are fmall, fcarcely as long as the thorax, and com- 
pofed of many joints of various fize and fhape, particularly thofe of 
the male. And therefore I do not comprehend what could induce 
Fabricius to call the joints equal, and the antenne moniliformes, 
efpecially as he adds that the latter are irregulares ; for this term, 
according to the fignification he has attached to it himfelf, flatly 
contradicts the former affertions.
