Dr. Arzertus’s Odfervations on the Genus Paufus. 263: 
fides and underneath, the foremoff above and on the fides convex 
refembling an annular fegment, and the Snder one impreffed in the 
middle with a mark fomewhat like two {mall diverging wings of a 
blackifh filvery colour. 
The Elytra are fhorter than the abdomen, and minutely punétated. 
The Under-wings are of a fhining and shaueeatae violaceous 
colour, and not very dark, 
The dédomen has the terminal fegment a little convex, and in the 
- female more fo-than.in the male. Underneath, the third and laft: 
fegments are darker than the others. 
The Feet are all of equal length. The ¢highs have fimaller ap- 
pendages than thofe of P. mucrocephalus. The legs are at the top 
broader, truncated and hairy, having the extericr margin drawn. 
out into-a fharp lamina, on each fide of which there is a row of 
{mall diverging hairs, which make the leg appear as if it were 
canaliculated, at leaft in a certain light,.and with a {mall magnifier. 
On the interior margin there is but one row of hairs, and on the 
hinder legs. I do not obferve any. The ¢arf are longer than thofe 
of P. microcephalus, and have alfo both the joints and the claws. 
-much more diftinét. 
Having thus. given a fufficiently detailed account of the genus. 
Paufus, and its two fpecies, which. I have {een’ myfelf, as to 
their hiftory, their generic refemblance, and {pecific difference, F 
fhall now endeavour to defcribe them in a fhorter and more f{cien- 
- tific language. 
In fettling his genera of infeéts, Linné attended chiefly to the 
antenné and their ftructure ; but he took occafionally into confider- 
ation alfo other parts, as the head, the thorax, the elytra, &c. &c. 
Fabricius has adopted a different method, and made out the generic
