Mimetic Relationships in the genus Heliconius. 107 



of pardalinus lucescens shown on PI. XIV is shorter and 

 broader than those already considered, yet, except in size, 

 there is no very satisfactory difference between it and that 

 of anderida zuleika on PI. XV, and some forms of anderida 

 are barely separable from aristiona. 



H. fortunatus, Weym. 



This and two subspecies occur in N. Brazil. I have 

 illustrated a clasper of fortunatus spurius on PI. XIV. It 

 is much more rounded than those so far considered. If 

 every specimen dissected out were identical with this, 

 then we might, perhaps, say that it differed constantly 

 from the other species, but a very small amount of variation 

 would make it as difficult to distinguish as the rest. 



H. quitalenus, Hew. 



The type form and three subspecies range through Peru, 

 Ecuador, Bolivia and N. Brazil. Reference to the drawings 

 on PI. XIV shows a marked difference between quitalenus 

 quitalenus and quil<denus felix. The first might well be a 

 variation of one of the forms of novatus. If the second 

 differs from these it does so no more than from its own type. 



H. anderida, Hew. 



The type and six subspecies range through Venezuela, 

 Colombia, Central America, and one form is said to have 

 been taken in Dutch Guiana. The claspers of six forms are 

 illustrated on Pis. XIV, XV, from which it may be seen 

 that there is considerable variation. There is less difference 

 between anderida holocophora and aristiona floridus than 

 between the former and anderida anderida. Kaye is of 

 opinion that anderida fornarina is either a good species or a 

 form of hceale. The clasper is, however, very near to that 

 of anderida mdicerla. and though hecale has a somewhat 

 different appearance it still seems connected with the other 

 forms of this group. 



H. paraensis, Riff. 



The two forms of this species are described from Para 

 and Itaituba respectively. A clasper of the form latus, 

 Riff., is illustrated on PI. XIV, and Is seen to be not satis- 

 factorily distinguishable from several of the other forms 

 described.
