146 Mr. Kirby on some new genera and species 



Genus. Cnemida. 



Nasus trapezoideus, apice subemarginatus subreflexus. 

 Antennce novem-articulatae : scapo (*) breviusculo incrassato; 

 articulis sequentibus quatuor subcyUndricis brevissimis, sexto sub- 

 pateraeformi ; capitulo triphyllo reliquam antennam longitudine 

 sequantem. 



MandibulcB extus bidendatae : dentibus obtusis. 

 Palpi articulo extimo subcylindrico, truncate. 

 ScapulariaX inter elytra et prothoracem]+ intrusa, ut mXJetonid 

 F. 



Prosternum || triangulare, pone basin bracbiorum § elevatum. 

 Mesosternum''^* obtusum, inter pedes intermedios subporrectum, 

 supra canaliculatum. 



Prothorax subbexagonus, latitudine longior, utrinque subfove- 

 atus, postice emarginatus. 



Scutellum elongatum, triaugulum isoscelem figurans. 

 Elytra humeris productis, rotundatis. 



Pedes, l^ibice femorum fere crassitudine : posterioribus qua- 

 tuor maximis. Cubitus XX apice tridentatus. Calcaria 1,2,2* 

 Tarn subclavati : unguiculis inaeqnalibus, 2, 2, 2. In manibus-^^ 

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

 ori magno truncate ; iuteriori minuto acuto ; in tarsis autem 

 quatuor posterioribus, unguiculus internus externo multoties 

 minor. 



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

 magno, subtrapezoideo. 

 Corpus 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 diflfers from the other insects of that family con- 

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