&. The younger males have the thorax coloured nearly as described‘ for the females, except that the brown 
has a metallic-blue reflection, the mid-dorsal carina is pale, but often there is no pale submedian stripe 
on each side of it; abdomen black, with two or three spots on each side of segments 2 and 3, a small 
basal spot on each side of 4 (and in some 5 and 6), and the large spot occupying the basal two-thirds of 
each side of 7, yellow. 
None of the present males have the tips of the wings brown. 
Q. Not all the present females have the tips of the wings smoky, ¢. g. those from Cuba, Coatzacoaleos, Salina 
Cruz, Tehuantepec, Gualan, Guayaquil, and some of those from Teapa; the presence or absence of this 
colouring does not seem to depend on age. Singularly enough, the only female taken in coitu, that 
from Gualan, has the internal triangle of both front wings 3-celled, but in all other characters agrees 
with equalis. 
The Venezuelan and Ecuadorian examples only differ from the others, so far as I can discover, in having the 
bases of the hind wings with a little more colour (brownish-yellow), reaching, in the males, in the 
subcostal and submedian spaces, out to the level of the submedian cross-vein and, in the postcostal space, 
back to the level of the apex of the membranule ; in the single female this yellow is clearer and reaches 
to the distal angle of the triangle and back almost to the anal “ angle,” with a still fainter yellow on the 
same part of the front wing.

The type of V. septima, Selys’, from Barranquilla, Colombia, is in the possession 
of Her Royal Highness the Princess Therese of Bavaria, who has graciously permitted 
Dr. F. Ris to study it. To him I am very greatly indebted for much information and 
help with this genus, and he has communicated the fact that this type is identical with 
equalis. The other individuals in the Selysian collection which de Selys referred to
