tibia with two pairs of spines; tlie tarsus ringed faintly at the joints 

 with light scales. 



Fore wing: basal area, median field and terminal space brassy 

 yellow which may be said to be the pervading colour, the purple- 

 brown body-colour appearing as minute powderings, sometimes 

 in the terminal space obliterating the yellow, except at the apex, 

 the ante- and post-median areas purplish, tempered by the body 

 brown, becoming more bluish in some specimens and exhibiting a 

 glistening sheen especially in the outer area. Maculation of the 

 usual pattern but not sharply drawn; basal line vague, except as it 

 outlines the basal spots which are yellow and never white; ante- 

 medial line brown, sinuous, extending close to the claviform, below 

 which, at the submedian vein, it outcurves to the inner margin; 

 median shade-line occasionally traceable as an angled brownish 

 shading, best defined in the lower median field ; the post-median line 

 geminate, the inner brown, the outer dull purplish, outcurved over 

 the cell, thence incurved with a nearly full ogee sweep to the inner 

 margin. The sub-terminal is very irregular, paralleling in a way 

 the outer margin, and consists of a series of dentations running 

 outward on the veins in little points. It defines the terminal area 

 with a glistening boundary that is not, however, very contrasting. 

 The fringes are slightly dentate, dull purplish and glistening. The 

 stigmata are of the usual formation, but not large; the orbicular is 

 rounded, white, with a yellow scale at centre; claviform double, 

 two spots in line with the orbicular, the upper minute and oc- 

 casionally yellow, the lower white. The reniform consists of a 

 lunulate, yellow marking around which are a number of small spots 

 clustered in the usual manner and cut by the veins, the innermost 

 usually white, the outer one yellow. The secondaries are smoky- 

 brown, shaded darker at the outer margin. The abdomen is of 

 similar hue. Expanse 32 to 43 mm. 



The male genitalia are generically typical and offer no particu- 

 lar specific feature. The corona is more fully rounded than most 

 of the allies, with the pollex prolonged prominently and at right 

 angles to the costa, and this section of the valva heavily spinose, 

 as is customary. At the clavus, or perhaps better defined as the 

 anterior margin of the sacculus, a patch of dense setae occurs.
