The medial carina of the frons becomes obsolete upon the vertex. 

 Lateral carinae of the prouotum rectilinear, and reaching the base. 

 Sometimes a black dot appears on each side of the presternum, above 

 the fore coxae. Ovipositor of the $ dark brown. 



I have found this species in one place only, on the Arundo pJir- 

 apnitis, surrounding a secluded pool in an osier bed near Leicester, in 

 August and September.
