Dr, Avzenius's Ob/ervations on the Genus Paufus. 249 
Linné clava, to which I alfo would add his other appellation of 
folida, € it could be done with any fort of propriety. By this 
epithet he certainly meant nothing more than integer, adopting it in 
contradiftin@ion to /amellatus and perfoliatus. And it anfwered the 
purpofe very well, as long as no other infe&ts were known than 
thofe having their clave entire and at the fame time folid. But now 
it would imply a contradiction, fince we have got a coleopterous 
infect with an entire clava though not folid ; which is undoubtedly 
the cafe as to P. fpherocerus, being provided with clave, or head-balls, 
almoft pellucid, and feemingly containing no fubftance whatfoever 
but perhaps fome fine liquid. As to the clavez of P. microcephalus 
Tam not fo certain, but they have alfo an appearance of being in- 
flated ; 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 {mall protube- 
rances, tipped with flefhy fubftances, like hairs, which probably are 
organs for feeling. 
The Mouth, and its different parts, as to their fhape and ftruéture, 
I have not been able to afcertain fo accurately as I could with, and as 
it ought to be done ; for, independent of their {mallnefs in fo little an 
animal, it is quite impoffible to defcribe them rightly, without their 
being taken feparate from one another ; and for this purpofe I had 
not any of thefe rare infe&ts to facrifice,: three of one fpecies and 
‘fix of the other being all which 1] have feen. Befides, the former 
were not my own; the latter I could fubje& to a clofer fcrutiny, 
not minding much whether any of them became broken. The
