582 Mr. Westwood'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 ^rthropterus. 



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 Hors^eldii.'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 (stride sic dictus). 

 Thorax latissimus, lateribus rotundatis. Antennce latissimse, lateribus serratis, 

 articulo ultimo maximo. Elytra abdomen tegentia. Tihice latissimse, spina 

 nulla interna [in C. A-maculato certfe bicalcaratae].1 



Species 1. Cerapterus latipes. Swed. 



" C. piceus ; elytris macula apicali flavescente subrotunda anticfe quadriden- 

 tata posticfe lobata ; antennis rufis, articulo ultimo in tuberculo ad basin 

 elevato." MacLeay. [Palpis labialibiis securiformibus secundum figuras 

 Swederi.] 



Habitat in Oriente.
