582 Mr. WEsrwoop's Synopsis of the Genus Cerapterus. 
with doubt, as identical with C. MacLeaii. Mr. MacLeay himself, the pos- 
sessor of the specimens described by Swederus and Donovan, having found a 
new species of the genus in Dr. Smith's African collection, published a Mono- 
graph of this genus in the first portion of the Annulosa of Dr. Smith's work, 
containing descriptions and figures of four species, namely, Cerapterus latipes, 
Horsfieldii, Smithii and MacLeaii, the last of which he separated as a distinct 
subgenus under the name of Arthropterus. | 
In a subsequent notice on this genus, rendered necessary by the publication 
of Mr. MacLeay's Monograph, I arranged the five species with which I was 
then acquainted in the following manner : 
Subgenus 1. Cerapterus propr. C. latipes. Swed.; and Horsfieldii. Westw. 
Subgenus 2. Orthopterus. Westw. C. Smithii. MacL. 
Subgenus 3. Arthropterus. MacL. C. MacLeaii. Donov. 
Subgenus 4. Phymatopterus. Westw. C. piceus. Westw. 
In addition to the species from South America mentioned at the commence- 
ment of this paper, I have further become acquainted with two more new 
species of this curious genus, sent to me by Mr. Westermann of Copenhagen, 
the possessor of a splendid collection of insects, and to whom I am indebted 
for many valuable additions to my collection. As one of Mr. Westermann's 
species and that of Mr. Miers constitute two remarkably distinct subgenera, 
it will be serviceable to offer the following synopsis of this genus, now con- 
sisting of eight distinct species. 
Subgenus 1. CERAPTERUS (stricté sic dictus). 
Thorax latissimus, lateribus rotundatis. Antenne latissimæ, lateribus serratis, 
articulo ultimo maximo. Elytra abdomen tegentia. Tibiæ latissimæ, spina 
nulla interna [in C. 4-maculato cert? bicalcaratæ |. 
Species 1. CERAPTERUS LATIPES. Swed. 
* C. piceus; elytris maculà apicali flavescente subrotundá antice quadriden- 
tata posticé lobatá; antennis rufis, articulo ultimo in tuberculo ad basin 
elevato." MacLeay. [Palpis labialibus securiformibus secundum figuras
