 Characteres ut in Exocentro, sed antenn'is attenuatis, elongatis, 

 articulo tertio quarto breviore, spina prothoracis in medio sita, 

 longe tenuata et recurva. 

 The long and slender antennae shut this genus out from the 

 genuine Exocentri, with which I had formerly arranged it. It 

 may be remarked that the femora are more clavate, and the 

 slender basal portion so lengthened that it is seen from above. 

 The single species upon which the genus is founded is remarkable 

 for the long hooked spine of the thorax, which is also slightly 

 bifid at the point of its greatest convexity.

 portion ; scutellum subtransverse ; elytra dark brown, with a
