ticed the formation of the tarsi of this species. Again in Trogosite vi- 
rescens, cerulea, and enea, which are proportionably much longer 
insects, and which, as their names import, are much more brilliantly 
coloured than the rest of the genus, the head is almost square, with three 
emarginations in front (Tab. Supp. XLvu. fig. 6.), the Jabrum is transverse, 
and slightly emarginated in front (Ibid. fig. 6.), the jaws are long, exserted, 
and acute at the tips (Ibid. fig. 6.), the last three joints of the antenne are 
much larger than the preceding (Ibid. fig. 6.), the mazille are long, and 
with one process only (Ibid. fig. 5, B.), the last joint of the maxillary palpi is 
nearly cylindric, and transversely truncate (Ibid. B.), the mentum is formed 
as in Trogosita Mauritanica, the labium is long, and its anterior half is 
divided into two divaricating lobes, which are ciliated, (Ibid. C.) The 
palpi are three-jointed, and affixed to long scapes united together, and 
their terminal joint is truncate, (Ibid. fig. 5,C.) The margins of the thorax 
are slightly notched in the centre, (Ibid. fig. 6.) the legs are longer than in 
Tr. Mauritanica, and the tarsi are only four-jointed, the three basal 
joints equally short, and the last joint as long as the three preceding, 
with a short style furnished at the tip with two diverging bristles between 
the two strong claws, (Ibid. E. and F.) These characters will, I have no 
doubt, be considered sufficiently strong to warrant my proposing the 
establishment of the insects exhibiting them, into a distinct genus, which 
I propose to name, from the divided labiwm, 
TEMNOSCHEILA.* 
In addition to the preceding, I have noticed several other forms of 
Trogosita in the cabinets of our entomologists, especially in that of the 
Rev. Mr. Hope. 
In order to render this paper as complete as possible, I now beg leave 
to add a few remarks upon the two remaining genera, which have been 
occasionally considered to belong to the family Cucujide, namely, Pa- 
randra and Hemipeplus. The observations which I shall have occasion 
to quote upon the genus i 
ParANpRA, Latr. (Isocerus, Illiger.) 
will perhaps be thought more generally interesting than any of the pre-~ 
ceding, in consequence of their shewing to us the recorded opinion of
