Dr. AfzeliusV Obfervatiom on the Genus Paufus. 255 



The Palpi are nearly of equal length, the anterior affixed to the 

 back of the maxillae, and the pofterior to the middle of the lip, the 

 former confiding of four joints and the latter of three. Fabricius 

 fays, that the palpi are filiform, and all their joints cylindrical, and 

 of the fame fizc. This may be true as to the hinder palpi, but it is 

 not equally {o in regard to the foremoft, as thefe latter have the 

 middle joints veficular and incraffated in the male, and obconical 

 with the terminal one much larger in the female. 



The Mandlbulce are toothlefs and without {heaths. 



The Lip is cylindraceous, elongated, and contracted where the 

 palpi are inferted, and above them bifid. 



The Thorax is Eat, but marked with no inequalities, being neither 

 depreded nor excavated. 



The Elytra are rounded at the end, and neither bent down there, 

 nor at the exterior margins. 



The Abdomen is furnilhed on the fides with papillary folds. 



The Tarfe of the fore feet have five joints, but thofe of the hinder 

 feet only four. 



Thefe few remarks may be fufficient to fhew that Cer&ccma is as 

 different a genus from Paufus as can be fuppofed, and perhaps 

 much more lb than many which Fabricius has eftabliihed. Having 

 thus far fettled the generic character, I mall now proceed to the. 

 hiftory and defcription of the fpecies in particular.
