j)alus. The armature of the tibiae is a more tangible character, 

 but Mr. MacLeay has either shown that he deemed it as of no 

 value, or has dreaded the establishment of a third subgenus for 

 the reception of C. Sinithii, [which differs from all the other 

 species in this respect. In like manner M. Gory's species will 

 not enter into the subgenus Arthropterus, as described by 

 MacLeay, so that its characters must be modified, and which 

 will render the following distribution of the species necessary: 



Subgen. I. — Cerapterus. 



Thorax latissimus lateribus rotitndatis : antennce laiissima; 

 laterihus serratis, articulo ultimo maximo : elytra abdomen 

 tegentia : tibice spina nulla interna. 



Habitat Asia. 



Sp. 1. The original C. latipes of Swederus, which Mr. Mac- 

 Leay characterizes thus: — "C piceus, elytris macula apicali 

 flavescente subrotunda antice quadridentata postice lobata, 

 antennis rufis, articulo ultimo in tuberculum ad basim ele- 

 vato :" and 



Sp. 2. The species which I doubtingly described as C. latipes, 

 suggesting that if distinct it should receive the name of C. 

 Horsjieldii. Mr, MacLeay, however, although stating this, 

 gives the reference to my name, C. Horsjieldii, with a mark 

 of interrogation. Mr. MacLeay's character of this species 

 is, " C. piceus, thorace antice emarginato, elytris macula 

 apicali flavescente baud rotundata literam Y quodammodo 

 simulante." 



Subgen. IL — Orthopterus, Westwood. 



Thorax latus fcapite haud duplo latior) : antennce longiores 

 sublatcB plana} lateribus siihrectis, articulo nltimo mediocri : 

 elytra abdomen tegentia : tibiae spino apicali intus instructed 



Habitat Africa. 



Sp. 3. O. Smithii, Westw. C. nigro-piceus, subnitidus : elytris 

 macula fulvd, thorace latioribus et fere quintuplo longiori- 

 bus. (Long. corp. lin. 7^.) 

 Habitat South Africa, within the tropic of Capricorn.
