244 Longicornia Malayana. 



apicem versus decrescenlia, luimeris rotundata, apicibus bi- 



apiculatis. Pedes mediocres, sub-aequales ; tarsi antici arti- 



culis tribus basalibus valde transversis. Pro- et meso-sterna 



elevata, hoc antice latioii, margine rotundato. 



This genus approaches Othelais and Dinllus in habit and in 



many of its characters ; from both it is distinguished by the short 



straiglit spine of the prothorax, and the broadly-transverse joints 



of the anterior tarsi. The tliree species described below are very 



distinct in coloration, but the sculpture is very similar, especially 



of the first two. The second antennal joint is more than usually 



elongate in this genus.
