146 Mr. Kirby on some nerc genera and species 

 Genus. Cnemida. 



Nasus trapezoideus, apice subemargiiiatus subreflexus. 



Ajitennie novem-articulatas : scapo (*) breviusculo incrassato ; 

 articulis sequentibus quatuor subcylindricis brevissimis, sexto sub- 

 paterae formi ; capitulo triphyllo reliquam antennam longitudine 

 ffiquantem. 



Maiulibulcc cxtus bidendataj : deiilibus obtusis. 



Palpi aiticulo extimo subcyliiidrico, truiicato. 



ScapulariaX inter elytra et prothoracem'+ intrusa,ut in Cetonia 

 F. 



Prosternum || triangulare, pone basin brachiorunn § elevatum. 



Mesosiernum** obtusum, inter pedes intermedios subporrectum, 

 supra canaliculatum. 



Prothorax subhexagonus, latitudine longior, ulrinque subfove- 

 atus, postice emarginatus. 



Scutellum elongatum, triangulum isoscelem figurans. 



Elytra humeris productis, rotundatis. 



Pedes. Tibice fcmorum fere crassitudine : posterioribus qua- 

 tuor maximis. Cubitus%X apice tridentatus. Calcaria l^l^^i, 

 T«rM subclavati : unguiculis iiiaeqnalibus, 2,2,2. In manibusW 

 unguiculus internus externo major est et apice bifidus: lobo interi- 

 ori magno truncato ; interiori minuto acuto ; in ta7'sis autcm 

 quatuor posterioribus, unguiculus internus externo multoties 

 minor. 



Abdomen segmentis duobus ultimis dorsalibus apcrtis : podice |||[ 

 magno, subtrapezoideo. 

 Co7-pus convexum. 



Having only single specimens, I have not been able to examine 

 the trophi of any species of this genus, but probably they are not 

 very different from those of the other Rutelidce; yet the mandibles 

 are less prominent. With regard to external and secondary cha- 

 racters, Cnemida differs from the other insects of that family con- 

 siderably. For instance, its front is distinguished by a long fovea
