112 Dr. H. Eltringham on Specific and 



from Colombia and Venezuela. A drawer filled with these 

 forms presents a most bewildering diversity of patterns 

 linked together by intermediate forms. On PL XVI I have 

 illustrated eight of the claspers. From these it will be 

 seen that there is a strong tendency for the point of the 

 clasper to be fuller and more rounded than in cydno and 

 some of the other forms. Two drawings are shown taken 

 from consecutive specimens of melpomene ihelxiope. The 

 difference between these is as great as that between the 

 second of them and one of the cydno forms, whilst that of 

 melpomene timareta contiguus is essentially of the cydno 

 pattern. 



H. amaryllis, Feld. 



The typical and two subspecies occur in Central America, 

 N.W. Brazil, Peru, Venezuela, Colombia and Trinidad. 

 Of the two claspers shown on PL XVI that of amaryllis 

 rosina euryas is of the cydno type, whilst that of amaryllis 

 euryades comes nearer to that of some forms of melpomene, 

 showing that here again this reputed species cannot be 

 definitely separated. 



H. vulcanus, Butl. 



The typical form occurs in Colombia and Panama, 

 and is rather doubtfully recorded from Guiana. The 

 form cythaera, Hew., occurs in Ecuador. Claspers of the 

 two forms are shown on PL XVI, and present no clearly 

 distinguishing features. 



H. xenoelea, Hew. 



This species appears as batesi in Stichel and Riffarth's 

 monograph, Riffarth having thought that xenoelea belonged 

 to the second section of the genus. Kaye pointed out the 

 error,* and has given the name microclea to the form in 

 Section II which resembles Hewitson's species. It occurs 

 in Ecuador and Peru, and is distinguished by the two 

 separate rounded spots on the fore- wing. 



The clasper figured on PL XVI is not distinguishable 

 from several of those already described. 



H. nanna, Stich. 



This reputed species occurs in S. Brazil, and a form 

 occurring further north, in which the fore-wing red discal
