V.—New Races and Aberrations of Heliconius. 
By J. J. Joicey, F.E.S., and W. J. Kays, F.E.S. 
[Plates V. & VI.] 
THE races and aberrations here described are all in the 
collection of Mr. J. J. Joicey at Witley. It will be noted 
that we have kept cydno as a species, and not treated it as a 
form of melpomene as Dr. Hltringham has maintained in his 
valuable paper in the Trans. Hunt. Soc. 1916, pp. 101-148. 
While we think his contention is possibly sound, we prefer 
for the present to keep cydno as a separate species, on account 
of the constant red markings on the underside. If ultimately 
cydno should be definitely proved to be conspecific with 
melpomene, one would expect this red marking on the under- 
side to occasionally occur in me/pomene races and forms in 
other geographical areas outside Colombia and adjacent 
portions of Venezuela. Southwards these forms are unknown ; 
only to the north, in Central America, are they further to be 
met with. ‘The two forms eratophylla and melpophylla—the 
one a subspecies of erato, the other a subspecies of melpomene 
—are of more than ordinary interest in the extraordinarily 
close resemblance they bear to one another, although of a 
complicated pattern. It is very curious to note that it is the 
yellow transverse band that has displaced a portion of the 
streaking in the erato form, but has filled up a vacant space
