a Family of Coleopterous Insects. 
683 
POSTSCRIPT. 
Since the preceding sheets were printed, Mr. Melley of Man- 
chester, the possessor of a very fine collection of exotic Coleo- 
ptera, has liberally submitted to my examination a remarkable 
new species of this family ; and I am happy in being enabled 
to add the following description of it, although I regret that, in 
consequence of the Plate having been completed, I cannot add a 
figure of it, and the more especially, since the insect in question 
is one of the most extraordinary in the family. From the forma- 
tion of the antennae and palpi it is clearly referrible to my new 
genus Platyrhopalus , and in the former of those organs most 
nearly resembles PI. Icevifrons; but in the extraordinary breadth 
of its elytra (which considerably exceed, in proportion to its size, 
even those of the Cerapterus Horsfeldii), and in its very broad 
and flat retractile legs, it evidently approaches Cerapterus. 
Mr. Melley informs me that a description and figure of it will 
shortly appear in M. Guerin’s Magazin de Zoologie. I am not, 
however, aware of the specific name which he is about to pro- 
pose for it, and am consequently restricted from introducing it 
in the ordinary manner with a nomen triviale, unless indeed its 
liberal possessor will allow me the honour of applying to it the 
name of 
Platyrhopalus Melleii, JVestw.
