In pattern characters this rare and remarkable butterfly be- 
longs, together with a few other genera or aberrant species, to 
what may be termed the “catochrysopoid” pattern group in 
Plebejince (some notes on the subject will be found further on 
and at the end of this paper), none of the members of this group 
having, however, any structural connection whatever with the 
Catochrysopince genitalically. Moreover, the present assign- 
ment of bornoi and jaga to the true Plebejince adds two “tailed” 
species to the small number (all in Chilades ) already known 
(first recognized by Chapman 1916).
