and cybele are the most fixed and definite races of this 

 section, the former giving fifty-five nearly typical examples, 

 and the latter fifty-one examples. Of funebris, of which 

 there are only four completely typical examples without 

 any trace of markings beyond the red basal area to the fore- 

 and hind-wing, there are interesting examples showing 

 that funebris is an extreme development of both cybele 

 and diana. Of the new forms negroida, maris, elegantula, 

 faustalia and dianides, the last is doubtless well known 

 but hitherto undescribed, but the remaining four, we think, 

 have probably never been seen before. Elegantula is at 

 once a development out of lucinda, and faustalia a develop- 

 ment of eulalia. Negroida is a striking aberration, and 

 quite unlike any already described form. It must be 

 looked upon as a parallel development to deinia, but 

 suffused heavily with black. Maris is a perfectly natural 

 advance on lucia as figured by Cramer (vol. iv, PI. 350, 

 fig. E), being simply the addition of the red base to fore- 

 and hind-wing. We are surprised that no intermediate 

 forms are available, showing either a red fore-wing base 

 only or a red hind-wing base only. The two red areas 

 are always present together, and this is the only 

 phase of variation where connecting forms are not to be 

 found. 



Unquestionably the most interesting form is the one we 

 name eltringhami in honour of Dr. Eltringham, who has 

 recently advanced our knowledge of the genus Heliconius 

 by his researches. This form, of which we have but one 

 specimen, is connected by two other forms to a more or 

 less typical deinia. One of these specimens is a deinia 

 form, but with the hind- wing basal stripe half red and half 

 yellow, the outer half being yellow. In the other specimen, 

 which is of the cybele type with the yellow spotting very 

 much reduced, only just the tip of the transverse red streak 

 is yellow. 



The aberrations which we herein describe appear to be 

 terminal developments in different directions, and as such 

 should be named, because it is possible and quite likely 

 that in certain localities these may have become races 

 of at least subspecific rank. In every instance except 

 eltringhami there are two or more identical specimens, 

 thus proving that these forms are recurrent, and there 

 are series of graduating specimens leading up to these 

 types.
