Dr. AfzeliusV Obfervatlons on the Genus Pan/us. 263 



fides and underneath, the foremoji above and on the fides convex 

 refembling an annular fegment, and the hinder one imprefled in the 

 middle with a mark fomewhat like two fmall diverging wings of a 

 blackifh filvery colour. 



The Elytra are fhorter than the abdomen, and minutely punctated. 



The Under-wings are of a mining and changeable violaceous, 

 colour, and not very dark. 



The Abdomen has the terminal fegment a little convex, and in the 

 female more fo than in the male. Underneath, the third and laft 

 iegments are darker than the others. 



The Feet are all of equal length. The thighs have fmaller ap- 

 pendages- than thofe of P. microcephalus. The legs are at the top 

 broader, truncated and hairy, having the exterior margin drawn, 

 out into a fharp lamina, on each fide of which there is a row of 

 fmall diverging hairs, which make the leg appear as if it were 

 canaliculated, at lead in a certain light*, and with a imall magnifier. 

 On the interior margin there is but one row of hairs, and on the- 

 hinder legs I do not obferve any. The tarfi are longer than thofe 

 of P. microcephalia and have alio both the joints and the claws* 

 much more diftindi.. 



Having thus given a fufficiently detailed account of the genus^ 

 Paufus, and its two fpecies, which I have feen myielf, as to- 

 their hiftory, their generic refemblance, and fpecific difference, I 

 fhail now endeavour, to defcribe them in a fhorter and more fcien- 

 tific language. 



In fettling his genera of infects, Linn6 attended chiefly to the 

 entennce and their ftruclure ; but he took occafionaily into confider- 

 ation alfo other parts, as the head, the thorax, the elytra, Sec. &c. 

 IFabricius has adopted a different method, and made out the generic 



5 defcriptions.
