V. — iV^ew Baces and Aberrations o/ Heliconius. 

 By J. J. JoiCEY, F.E.S., and W. J. Kayb, F.E.S. 



[Plates V. & A^.] 



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 imdpomene as Dr. Eltringliam has 'maintained in his 

 valuable paper in the Trans. Eut. 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 tlie 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 melpomene races and forms in 

 other geographical areas outside Colombia and adjacent 

 portions of Venezuela. Southwards these forms are unknown j 

 only to the north, in Central America, are they further to be 

 met with. The two forms eratophylla and melpophjlla — the 

 one a subspecies of erato, the otlier 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 tiansverse band that has displaced a portion of the 

 streaking in the eralo form, but has filled up a vacant space
