124 Dr. H. Eltringham on Specific and 



fore-wing evidently bears a close affinity in the two species. 

 If tumatumari be carefully examined in a good light, it 

 will be seen that on the hind-wing underside the brown 

 colour above the cell is very dark, whilst beneath this 

 dark area is a paler stripe traversing the cell, its hinder 

 border line passing out of the cell exactly at the origin 

 of the second subcostal branch. The positions of these 

 dark and light areas correspond precisely with those of 

 the black-brown and orange-browu in vetustus, whilst 

 there is an orange-brown streak below the cell in vetustus 

 corresponding accurately with the distinctive yellow 

 streak in tumatumari. Taken singly these points may be 

 small and might be accidental; collectively they appear 

 to me to be very significant. 



H. elevatus, Nold. 



It is scarcely surprising that this species has been 

 regarded as a form of melpomene. There is practically 

 no external feature to distinguish it, beyond the yellow 

 streak already referred to, yet it is more nearly related 

 to some of the Silvaniformes than to melpomene. Three 

 male examples are before me from Chanchamayo, Sao- 

 Paulo (Amazon), and Beni River (Bolivia) respectively. 

 The first two agree nearly with the description of elevatus. 

 The third differs in the following respects. The fore- wing 

 discal yellow fills the outer third of the cell, and extends 

 across the space between the first and second median, and 

 as a suffusion half-way down to the sub median. On the 

 margin of the hind-wing underside it has very distinct 

 white dots, absent in the two other specimens. These 

 dots are described as occurring in the type. In all three 

 the hind- wings above have an orange-red horizontal 

 band passing through the cell and ending beyond the 

 subcostal. This is followed by the usual straight band of 

 black, and seven orange-red internervular " nail-headed " 

 streaks almost reaching the hind-margin. 



As has been stated, the armature approaches in structure 

 that of sergestus. If there is any real affinity there is no 

 indication of it on the upper surface. On the under 

 surface, when the third specimen described above is 

 compared with sergestus, we find that the position and 

 general contour of the fore-wing discal yellow is very 

 similar to that in sergestus. The latter furnishes one of 

 the rare cases in which a silvaniform Heliconius has a red
