274 Longicornia Mnlayana. 



brevioribus, ultimo longissimo ; (j) corpore longiores, ar- 



ticulo quarto tertio breviore ; ultimo praecedente paulo 



longiore. Prothorax transversus, utrinque fortiter spinosus, 



apice uni- et basi bi-sulcatus. Elytra convexa, apicem 



versus angustiora, apice rotundata. Pedes robusti, sequales ; 



femora linearia ; tib'KE anticae vix curvatae ; tarsi dilatati, ar- 



ticulo ultimo mediocri. Prosternum simplex. Mesosternum 



elevatum, productum. 



The principal characters of this genus are the great length 



of the antennae in the males, and the linear femora, which, 



as well as the tibiae and tarsi, are only slightly variable in 



length in all the legs. The nearly straight anterior tibiae and 



more or less elevated mesosternum are also to be remarked in 



conjunction with other characters. Two very fine and noble 



species, but varying very much in size, are comprised in this genus ; 



three others, which I have also referred to it, must for the present 



remain somewhat doubtful, as I have seen only one example of each, 



and these are so remarkable that I have given a figure of each.
