632. Mr J.O. Wzsrwoop on the Pausside, 
As this species has already been very fully described by 
Afzelius, I shall not recapitulate its specific characters. It 
is necessary, however, to make a few observations upon the 
species, in consequence of the Linnean cabinet at the present 
time not possessing the original Linnean specimen, a distinct 
species being attached to the Linnean generic label. For the 
purpose therefore of identifying the species, I beg to direct 
attention to the size of the insect, which is stated in the original 
description to be equal to Dermestes lardarius, and also to the 
original figures, which are sufficiently exact to convince the 
student that the specimen originally contained in the Banksian 
cabinet, and now belonging to the Linnean Society, is the 
P. microcephalus: it is true, that Afzelius states that he only 
casually examined the Linnean insect in the possession of our 
late lamented President; but it is not to be supposed that 
Afzelius, himself the capturer of one of the species, could have 
mistaken any other species which might at that time have been 
introduced into the Linnean cabinet when he examined it; and 
this is rendered more unlikely, from the circumstance of the 
original figures of the insect having been drawn by J. Afzelius. - 
Whence the first above-mentioned circumstance has arisen may 
perhaps be learned by tracing the history of the three specimens 
known to Afzelius. ‘That in the cabinet of Sir Joseph Banks 
now belongs to the Linnean Society (from which both Afzelius's 
and my own figures were drawn). The second, originally in 
the cabinet of Mr. Drury, I understand subsequently came. 
into the possession of Mr. MacLeay: but of the third spe- 
cimen, originally belonging to Linnæus, I can discover no 
trace. It appears, barare, in the Histoire Naturelle &c. that 
Latreille received from “un des naturalistes de l'Angleterre le 
plus estimable par ses connoissances, par ses communications 
amicales, Alexandre MacLeay,” three species of the genus, but 
- which
