S ? . Gcnal process very obtuse, shorter than pilifer ; a tuft of scales below 

 pilifer as in the allied genera. Palpus not projecting, with rough hair-scales at 

 sides ; patch of sensory hairs on innerside at the base vestigial. Head sunken, with

 of midtibia nearly equal in length. Distal margins of wings uneven or denticulate ; 

 hinder angle of cell of liindwang more or less acuminate.

S ?. Some specimens are far more grey on body and forewing, and have more 

 conspicnous markings than others. The two forms intergraduate, however, as the 

 series now in the Tring Museum shows, and are the same in structure ; pnlchcrri- 

 mam sinks, therefore, as a synonym. 



c?. Tenth tergite mesially grooved above, rather flat, convex at end which is 

 rounded (PI. XLIY. f. 37) ; sternite (A>) broader than the tergite, not strongly 

 chitinised, rather suddenly acuminate. Clasper rounded sole-shaped (PI. IL. f 'Zf<) ;
