ticed the formation of the tarsi of this species. Again in Trogositce vi- 

 rescens, ccBTulea, and asnea, which are proportionably much longer 

 insects, and which, as their names import, are much more brilUantly 

 coloured than the rest of the genus, the head is almost square, with three 

 emarginations in front (Tab. Supp. XLVli. fig. 6.), the labrum 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 antennceare 

 much larger than the preceding (Ibid. fig. 6.), the maxilla are long, and 

 with one prodess only (Ibid. fig. 5, B.),the last joint of the maxillary palpi is 

 nearly cylindric, and transversely truncate (Ibid. B.),the menfum 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 suflRciently strong to warrant my proposing the 

 establishment of the insects exhibiting them, into a distinct genus, which 

 I propose to name, from the divided labium, 

 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 Cucujidce, namely, Pa- 

 randra and Hemipeplus. The observations which I shall have occasion 

 to quote upon the genus 



Parandra, 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 



• Tifivo scindu et x<(Xoc labium.
