620 Mr. J. O. Westvvood on the Paussida, 



who, with a liberality as disinterested as rare, permitted me not 

 only to examine, describe and figure, but also to relax his spe- 

 cimen, thereby enabling me to render my paper more complete 

 by adding figures of its various characters, especially of the 

 trophi, which from their size I was able to effect with facility, 

 and which, together with the other dissections figured by me, 

 are the first representations which have been given in detail of 

 those most valuable organs in the family. Of its locality that 

 gentleman can give me no further information than that it came 

 into his possession in a large box containing chiefly African in- 

 sects. 



Genus 2. Paussus. Linn., Fabr.t Latr., ^c. 



Pausus. Thunb., Afz., ^c. 



Type of the Genus P. microcephalus Linn. 



It is not my intention to detail the characters of this genus, 

 the Transactions of this Society being already enriched with 

 the elaborate details given by Afzelius. I however insert the 

 cibarian characters, in consequence of the confusion existing in 

 the writings of Afzelius and Latreille upon their nomenclature 

 and formation. A considerable portion of the following cha- 

 racters is indeed derived from their researches, but those of the 

 lower lip and its appendages are the result of my own dis- 

 sections. 



Corpus subdepressum. Caput mediocre, thorace angustius, pos- 

 tic^ coUo brevi instructum. Antenna magnae, articulo Imo 

 minori, crasso, cylindrico-ovato, apice obliqufe emarginato, 

 tunc articulus ? parvus, subglobosus, emarginaturae prioris 

 immersus, cui insidet articulus ultimus maximus saepiils ir- 

 regulariter obtrigonus, compressus vel subdepressus, angulo 

 infero et externo interdum uncinato. Labrum subcoria- 

 ceum, parvum, transversum, angulis anticis rotundatis.
