dark fuscous raised scales from below this dot to below fold, edged with 
white posteriorly; three dots closer to each other along costa from middle 
to before s / 4 ; three smaller discal dots below those, so as to form together 
with the above mentioned costal dots an invert triangle, with top reaching 
halfway across wing; two posterior discal dots followed by white raised 
scale tufts ; two small black points on apical 1 / 6 of costa ; a small transverse 
dorsal mark on end of fold; a row of small dots along termen and in
