25. — HELICONIUS XANTHICUS. 



Agrees with S. Jucundus in every respect, except that the macular 

 belts of fore-wing above and beneath, and the apical spot of the hind- 

 wing above, are yellow instead of white ; and that the costa of hind- 

 wing has a sub-marginal black stripe. 



Several examples in company with S. Jucundus, Panama. This 

 form, whose distinctness from S. Jucundus must at present remain a 

 matter of doubt, connects S. Jucundus with H. Zuleika (Hewits), an 

 inhabitant of the same countries. 



26. — HBLICONIUS MAGDALENA. 



Same in size and colour as S. Bhea (Cramer, 54, c.d.). Differs 

 constantly in both the yellow belts being linear and narrow instead of 

 oblong aiid broad. The inner belt consists of the same number of spots, 

 but it is only one-half the breadth of the same belt in S. Bhea, and 

 terminates in a point on the first median branch nervure. The apical 

 belt is narrow, and extends nearly across the wing to the outer border. 

 Another point of distinction from H. Rhea is a narrow white edging or 

 fringe to the hind-wing, always very conspicuous in //. Magdalena, but 

 scarcely visible in S. Rhea. Beneath : the same, except that the pos- 

 terior line of red spots in hind- wing is seldom present in H. Magdalena. 



This form takes the place of the Guiano- Amazonian U. Rhea in the 

 valley of the Magdalena and neighbouring regions in New Granada. 

 It seems to be common on the Isthmus of Panama. 



27. — HELICONIUS VEB^PACIS. 



Closely allied to S. Rhea and S. Magdalena ; differs in the shape 

 and colour of the pale belts. In colour they are much paler, the apical 

 one especially being nearly white. The basal belt is as broad as it is in 

 H. Rhea, but it consists of four distinct spots, and commences in a 

 square form near the costa, terminating in a point on the first median 

 branch nervure. The apical belt is very short, narrow, and interrupted. 



This form was found only in the province of Verapaz, interior of 

 Guatemala. AU the examples taken agree perfectly in their points of 

 difference from allied forms.* 



• Heliconius Sprticei. Similar to B. Shea and H. Magdalena, but smaller, 2" 5'". The white 

 fringe of the hind-wing is very conspicuous, owing to the edae of the wing itself being also white, and 

 thi! outer border of the fore-wing is edged with white. Yellow belts of the fore- wing the same in breadth, 

 position, and colour as in S. Magdalena. 



Western side of Chiraborazo, at an altitude of 8-4000 feet. Tslfen in great numbers by Mr. Spruce. 

 All the examples agree perfectly in their distinctive characters.
