TAURIPHILA. 297 
[BB. Hind wings with 5-6, usually 6, antecubitals and a brown nodal point, 
membranule white or pale grey ; all wings with more often two rows of cells 
in the middle of the field between subnodal sector and supplementary sector 
next below Ce ee ee ee ee ee we ist *.] 
AA. Hind wings with two (occasionally three) post-triangular cells followed imme- 
diately by three rows (formula 2, 3, 3,3,3.... or 3,3,3,3,3... .)3 all 
wings with more often two rows of cells in the middle of the field between sub- 
nodal sector and supplementary sector next below. 
C. Abdominal segments 3-6 with a transverse apical black band occupying a fifth 
or a sixth of the length of the segments, confluent with a mid-dorsal black 
line which is triangularly dilated at the bases of 5-7 and is widened into a 
band on 8 and 9; superior appendages of male asin A above . . . 2. azteca. 
CC. Abdominal segments with no transverse or mid-dorsal bands ; superior 
appendages of males in dorsal view converging, in profile view proximal two- 
thirds of upper edge strongly convex, terminal third nearly straight, denticles 
of lower edge beginning at two-fifths’ and ending at two-thirds’ length of the 
appendage. 2. 1. ee ee ee eee BL GO.

Hagen says of the brown spot on the base of the hind wing of the female of australis that it “bis zum Dreieck 
oder selbst hineinragt”!, and of the same spot of the male of iphigema “ triangulum non attingente ”°*. 
In the present material, it is only in three of the Samana, the Cuban, and the Bonda males that the brown 
reaches the triangle and in them only by a slender limb along the posterior side of the submedian vein ; 
in the fourth Samana male it does not reach farther out than barely beyond the level of the first ante- 
cubital ; in all the other males to scarcely beyond the beginning of A,. In the females the distal limit 
is the submedian cross-vein (Teapa, Guayaquil, Turbo, Cuba), or origin of A, (Bonda). The posterior 
extent of the basal marking is shown in the table below :—
