Male, — Length 11-5-12 mm. ; wing 14*4-15 mm. ; an-

 antennae and the coloration of the wings and abdomen. 



Compared with binotata, the present species differs as 

 follows : — 



Antennae of male approximately one-half longer than the 

 body. Vertical tubercle more prominent. Wings with the 

 ground-colour yellowish grey, the ocellate spot at mid-length
