244. Dr. Arzexius’s Obfervations on the Genus Paufus. 
But whether this etymology and explanation be right or wrong, I 
cannot find any better; and thus I am induced to follow Thunberg, 
Gmelin, and Herbft, in their mode of fpelling Pau/us with one /, 
being as to my idea the moft rational. 
Linné knew but one fpecies of this genus, from which he took 
the generic charaéter, and which he called (ftom pups and xegaa%) 
micro-cephalus, on account of its head being very. {mall in proportion 
to the other parts of the body. It is fhortly defcribed in the dif- 
fertation above-mentioned, and five figures of it fubjoined, reprefent- 
ing it in different views, two in its natural fize, and three in a 
magnified one. 
After this original account of Linné, there have been very few 
authors that have publifhed any thing concerning Paufus. Thofe. 
J have had an opportunity of feeing, and I think I have feen 
all, are the following; and whofe writings I fhall mention in the 
fame chronological order as they have appeared. 
Thunberg, during his travels in the country of the Hotentots, in 
the year 1772, having met with two unknown infects, defcribed 
them as conftituting a new genus in the clafs of Coleoptera. But 
having returned to Sweden, and being then acquainted with the 
Paufus of Linné, he thought his two fpecies might be referred to 
this genus, eftablifhed during his abfence; and accordingly he 
wrote a paper on the fubject, which he delivered to the Royal Aca~ 
demy of Science at Stockholm, and which is printed in its Tranf- 
actions for the year 1781.—Here he defcribes and {pecifies his two 
infe@ts, calling the one Paufus ruber, and the other Pau/us lineatus ; 
annexing two figures of the laft mentioned, one fhewing it in its 
natural fize, and the other reprefenting it magnified. He alfo makes 
fome few additional remarks on the genus itfelf, and gives the 
{pecific difference of P. microcephalus.
