582 Mr. Westwood's Si/nupsls of the Genus CVrapterus. 



with doubt, as identical with C IMacLeaii. Mr. MacLeay himself, the pos- 

 sessor of the specimens described by Swederus and Donovan, liaving 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, Smithil and MacLea'ii, 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.hifipes. Swed. ; and Horsfie/dii.Wef^tw. 



Subgenus 2. Ortliopterns. Westw. C. Smithil. MacL. 



Subgenus 3. Arthropterus. MacL. C MacLeaii. Donov. 



Subgenus 4. Phi/mufopterus. Westw. C. piceus. Westw. 



In addition to tlie species from South America mentioned at the comuience- 

 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 oflfer the following synopsis of this genus, now con- 

 sisting of ciglit distinct species. 



Subgenus 1. Cerapterus (stricte sic dictus). 

 Thorax latissimus, lateribus rotundatis. Antenmv latissimœ, lateribus serratis, 

 articulo ultimo maximo. Elytra al)domen tegentia. Tihia' latissimœ, spina 

 nulla interna [in C. A-maculato certe bicalcaratse].] 



Species I. Cer.\pterus latipes. Swed. 



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

 tatâ posticè lobatâ ; antenais rnfis, articulo ultimo in tuberculo ad basin 

 elevato." MacLeaif. [I'alpis labialibus secnriformibus secundum figuras 

 Swederi.]
