Dr. Afzelius'j Obfervalbns on the Genus Paufus. 249 



Unn6 c/ava, to which I atfo would add his other appellation of 

 fihda, if it could be done with any fort of propriety. By this 

 epithet he certainly meant nothing more than wA?#fr, adopting it in 

 contradiftindion to lamellatm and perfilhtus. And it anfwered the.' 

 pnrpofe very well, as long as no other infects were known than 

 thofe having their clavaD entire and at the fame time folid. But now 

 it would imply a contradiftion, fince we have got a coleopterous 

 infea with an entire clava though not folid ; which is undoubtedly 

 the cafe as to V.fpharocerus, being provided with clava?, or head-balls, 

 almoft pellucid, and feemingly containing no fubftance whatfoever 

 but perhaps fome fine liquid. As to the clava? of P. microcephnlus 

 I am not fo certain, but they have alfo an appearance of being in- 

 flated j and befides, as they are larger than the whole head, one 

 would fuppofe them too heavy to be carried in the front, if quite 

 folid. However this may be, the word is ftill improper in regard 

 to the other fpecies, and I .fhall therefore avoid ufing it. The 

 under-joints of both fpecies are almoft parallel, but the upper ones 

 very diverging. On the vertex of thefe latter, at the end of the 

 raifed line above defcribed, there are one or more fmall protube- 

 rances, tipped with flefhy fubftances, like hairs, which probably are 

 organs for feeling. 



The Mouth, and its different parts, as to their ihape and ftruclure, 

 I have not been able to afcertain fo accurately as I could wifh, and as 

 it ought to be done ; for, independent of their finallnefs in fo little an 

 animal, it is quite impoffible to defcrihe them rightly, without their 

 being taken feparate from one another ; and for this purpofe I had 

 not any of thefe rare infects to iacrifice, three of one fpecies and 

 fix of the other being all which I have feen. Befides, the former 

 were not my own ; ths latter I could fubjecl to a clofer fcrutiny, 

 not minding much whether any of them became broken. The
