260 Dr. Arzexius’s Obfervations on the Genus Pau/us, 
at their top rounded, and provided with fhining hairs of a fulvous 
colour, and incurved downwards. 
The Evra are without dots, and rather longer than the abdomen. 
The folds of the exterior borders, and the tubercles on the outer 
angles of the ends, are both larger than thofe of P. /pherocerus. 
The Under-wings are quite footy, and without the leaft gloffinefs. 
The Aédomen has the terminal fegment very retufe, and the mar- 
gin of the next before it vifibly raifed. 
The Hinder-feet are a little fhorter than the others. The high 
of thefe feet are larger than thofe of P. /pherocerus. The legs of 
the four foremoft feet are linear, but thofe of the two hindmoft 
ones nearly lanceolated, being alfo fomewhat broader. The joints 
of the ¢arfi are exceedingly difficult to be diftinguithed.
