86 Mr. J. O. Westwood’s Descriptions of 
cript name of Xiphocera brunnea of Latreille. Having been kindly 
permitted by its conscientious possessor to examine and figure 
this insect, I have not the least doubt of its specific identity with 
the Paussus Klugii, notwithstanding M. Buquet’s insect is from 
Senegal, and Dr. Klug’s from the Cape of Good Hope. The 
structure of the head, antennae, and thorax, is precisely similar, 
the latter being furnished with the two sericeous patches which 
especially distinguishes this species. The elytra are similarly 
subnitidous, finely punctured with a marginal series of hairs. The 
specific name given to the insect by Latreille, brunnea, indicates 
its colour, which is entirely dark-castaneous, with the elytra ru- 
fescent at the side. In this respect it therefore differs from the 
typical specimens of Paussus Klugii, but as the specific dis- 
tinctions of this family consist of structural variations, and not 
of differences of colour, I can only think this a variety of the 
former. Moreover, as it is also certain that variation in the 
formation of the antennae is in this group only of specific and not 
of generic rank, I cannot adopt Latreille’s idea relative to the 
generic distinction of this insect from the true Paussi ; if indeed we 
were to proceed in the other manner, it would be necessary to 
form almost every species into a distinct genus. 
It is a curious point in geographical Entomology, that a species 
of this curious and very rare genus should be so widely distri- 
buted as to be found both in Senegal and at the Cape of Good 
Hope. The same observation has however recently been made 
upon other insects.
