In the number of the joints in the antennse this genus stands 
alone in the family; several of its species, however, exhibit rela¬ 
tions with some of the genera ; thus Cerapterus latipes hears a 
strong resemblance to Platyrhopalus Mellii; the Australian species 
in their simple-formed prothorax and general form resemble the 
species of Paussi in which the prothorax is not bipartite, whilst 
C. Westermanni in its slender legs and dilated prothorax resembles 
Lebioderus. 
Mr. MacLeay, in 1838, in his Paper on this genus, (introduced 
into Dr. Smith's Illustrations of the Zoology of South Africa, in 
consequence of a new species of the genus having been brought from 
thence by that naturalist) published figures of four species. I am 
now enabled by the kindness of several correspondents to describe 
as many as nino distinct species, which may be divided into the 
following subgenera. 
Sub-Genus I.—CERAPTERUS (stride sic dictus). 
Prothorax latissimus, latcribus rotundatis, antenna? latissiraa? lateribus serratis articulo ultimo 
tnaximo. Elytra abdomen tegentia. Tibia? latissimae (in C. 4-maculato bicalcarata?, iu 
reliquis ecalcaratae). Scutellum mediocre. 
Species l.^Cerapterus latipes. (Plate 49, fig. 1.) « C. piceus ; elytris macula apicali fla- 
vescente subrotunda antice quadridentata postice lobata ; antennis rufis articulo ultimo in

Ihe above description and the accompanying figure are taken 
from Mr. MacLeay’s memoir above referred to, as that gentleman 
now possesses the original and still unique specimen described by 
Swederus, who states that it came from Honduras ; but Donovan, 
on the authority of General Davies, the original possessor of the 
insect,^ stated it to be a native of Bengal. Mr. MacLeay further 
adds. Thorax capite duplo latior medio postieeque litrinque foveo-
