Nearly allied to the preceding species, but larger, greyer, with the outer margin of the 
primaries less strongly dentated, the spot near external angle smaller, and the dusky lines 
difi'erent in direction; the secondaries altogether deeper in colour, with broadly diffused 
smoky brown outer border, and smaller black spots at anal angle ; thorax darker, with less
