l^arva given, gramilosc, a dorso- lateral scries of jwinled tubercles from 

 ])ronotiiiu to liorii. Head produced dorsad into a long jjrocess, whicli is siunatc at 

 end ; in last stages the ])rocess lias disa]iiicarcd, llie liead becoming only m<ulerateiy 

 triangular. Hum first long and slendei-, straigiit ; in later stages rather sliort and 

 stout, curved.

c??. Tliis form only has been dissected by us; tiie above description of tlie 

 structure of the se.xual armature ajiplies, therefore, to the present subspecies. The 

 third antemedian line of the forewing, above, is undulate, the brown marginal area 

 of the up{)erside does not reach hinder angle, and that of the underside is of nearly 

 the same tint from the apex of the forewing to the anal angle of the hindwing. The 

 dot at the base of the forewing is mostly double, or the (hits are fused to one; 

 seldom is one of them absent.

 antemedian line almost straight, first discal line less straight than in ijrayi : brown, 

 marginal area extending to hinder angle, its inner edge almost evenly curved ; 

 marginal area of underside of both wings not distinctly browner than disc, except 

 below apex of forewing and at anal angle of hindwing. Structure of the eighth 

 tergite and of the vaginal armature not examined.

 ])oints : Forewing; the basal dot replaced by a short inconspicuous line; antemedian 

 lines 1 and "J + :5 converging costad; the brown apical area not narrowed to a point 

 at the apex of the wing, but remaining here several mm. broad ; a brown are alike 

 this also present on the underside, but here smaller, stopping at E'', rather sharply 

 defined ; the hindwing, below, dark brown at apex as well as at anal angle, the 

 j)ostdiscal line less curved than in (/ray/. — Not dissected.
