Dr. Arzeuius’s Ob/fervattons on the Genus Paufus. 257 
Now I find from thofe of his manufcript papers which Mr. 
Drury obligingly has permitted me to perufe, that though he often 
travelled to different places between Ifles de Lofs and Sherbro’, 
fill he refided chiefly at the Bananas ;—and therefore I think we 
fhall not be much miftaken, if we confider this ifland, or the adjacent 
part of Sierra Leone, as the only native country hitherto known of 
P. microcephalus, this rare infect, of which there are no more to 
my knowledge now exifting in Europe than the three fpecimens 
before-mentioned, all of which I have feen, but in a very different 
manner ;| for, of the Linnzan one, now in the poffeffion of Dr. Smith 
at Norwich,-I had only a curfory view, at a time when I entertained 
no idea of defcribing it; but the other two I have been allowed to 
examine and compare carefully. And as the figures annexed to 
Linné’s differtation, though upon the whole of merit, were found 
to be capable of conveying a wrong notion of the true ftructure of 
the antennz, and principally of their fuperior joint ; Sir J. Banks 
did me the favour of granting me leave to have his fpecimen drawn 
in different fizes and pofitions. . 
- _ Linné defcribes this infe& as niger elytris piceis, Thunberg and 
Gmelin as totus niger, and Fabricius as fu/cus.. Herbft calls it afer, 
but figures the elytra piceous, and the reft of the body blackifh- 
cinereous ; and thus makes it very curioufly refemble an harlequin. 
As to Fuefsly, he has only copied Linné’s words; but in the French 
edition both niger and ficeus are tranflated by noire-—Hence we find 
that this infect has been defcribed now with one colour and now 
with another, and fometimes as having two colours, though it does 
not poffefs but one, and that almoft uniform. This is a fingular 
fact, and a ftriking inftance of authors not knowing the true figni- 
fication of Linné’s terms.
