128 Dr. H. Eltringham on Specific and 



is amaryllis euryades, lacking the yellow band on both 

 surfaces of the hind-wing, though in the form euryas 

 it is present on the underside, and in one example 

 before me from the Rio Dagua there is a trace of a 

 white submarginal band on the hind- wing underside. 

 These forms bring us to melpomene, fig. 20, which is 

 merely a modification of the form of heurippa shown at 

 fig. 12. All the yellow has disappeared and nothing but 

 the bright red fore- wing patch remains. Occasionally an 

 example of melpomene may be found in which the dull 

 brown of the hind-wing underside has a rather lighter 

 appearance corresponding in position to the yellow band 

 of other forms. 



Fig. 21 is the form described by Lathy as xenoclea 

 confluens. It may be regarded either as a xenoclea in 

 which the two patches have run together, or more prob- 

 ably as a melpomene with an extended patch not yet 

 separated into two. In any case it connects melpomene 

 with xenoclea, shown at fig. 22. In fig. 23 the two 

 patches of xenoclea are white with a dusting of red. The 

 example shown at fig. 24 exhibits the well-known " flame " 

 pattern in the hind-wings together with basal red in the 

 fore- wing. The flame pattern occurs in many forms of 

 melpomene and also in species of Section II, though in the 

 latter the red streaks radiate from the borders of the cell 

 and have not the appearance of being horizontally cut off 

 at their upper end. 



Fig. 25 represents melpomene eulalia, in which, as in 

 fig. 26, we see a distinct trace of the heurippa band in the 

 fore-wing, the flame pattern recurring in fig. 26. Fig. 27 is 

 a remarkable combination of the melpomene amandus f ascies 

 with the flame pattern superimposed. Finally, fig. 28 

 shows H. pachinus. The genitalia of this cannot be dis- 

 tinguished from those of all the other forms shown on the 

 plate, and as to pattern, the yellow bands appear to be 

 a mere modification of those of the fore- wing of figs. 3 

 and 6 and the hind-wing of fig. 4. Moreover, on the 

 und rside of pachinus there is frequently to be seen on 

 the hind-wing a submarginal series of white spots like the 

 vestige of the white border of cydno. 



I have discussed the melpomene association at some 

 length because I happen to have had access to a great 

 number of examples, and these fortunately exhibit remark- 

 able intermediate forms, which, together with the pre-
