114 Longicornia Malayana. 



rotundatiis. Elytra brevia, basi callosa, luimeris baud pro- 



diictis. Pedes breves, siibaequales ; tarsi antici baud dilatati. 



Mesosternum paulo pioductum. /Abdomen segmento ultimo 



elongate. Corpus subdepiessum. 

 I bave separated tbis genus from Cacia, to wbich 1 fornfierly 

 referred it, on account of its sbort antennae in botb sexes, its 

 elytra being callous at tbe base, and its mesosternum being simply 

 produced anteriorly, not baving a distinct tooth. The legs also 

 are shorter and the body more depressed than in any species of 

 Cacia. My original specimen was much worn. These insects 

 were taken flying in the jungle.
