middle; an irregular brown partially black-margined fascia from costa 
before middle to anal angle, anterior edge with a short median projection

Appears to vary very little. 
From the female of a pair taken in cop. Mr. Fereday obtained eggs which 
hatched out in February, but the young larve refused all kinds of food- 
plants offered, and died. At this stage they were 10- legged, very slender, 
dark purplish-brown, almost black; spiracular creamy- -white, wrinkled ; 
head shining pale brown.
