as broad ; areolet entire and sometimes sessile, emitting the 

 recurrent nervure but very slightly before its apex ; nervellus 

 distinctly geniculate below its centre and sometimes emitting a 

 distinct nervure. 



lianye. Europe, Assam. 



This genus was erected with no type ; but recently Professor 

 Schmiedeknecht, following Tschek, has reierred Pi/ r acmon f ale i pes, 

 Holmg. (Sv. Ak. Handl. 1858, p. 102) to it. An Indian pair, 

 ditfering only in the absence of the clypeal production and in the 

 shape of the areolet, appears also to belong to it.
