 The first three anteniuti lamellae are much shorter than the last three. 

 Although the elytra are united in most specimens' the lateral and interme<liate areas 

 of the metasternum are tli.stinet. This is also the ca.se in Plmrnriiis hr<trhiji>hifU>is, from 

 the Indian Peninsula,' a species in which the elytra are coiu-ave between the shoulders and 

 the wings show little or no trace of reduction. The elytra of the present spe<-ies are 

 convex between the .shoulders and the wings or always reduced, being intermeiliate in 

 form Iwlween those of I'UurariH.s hrnrhifphylh(.s and those of Marrolnni.s iJmsu.s.
