fuscofasciata, Blanch.”, to Uracis infumata, Ramb., but I see no reason for rejecting Hagen’s identi- 
fication® *, adopted above. Blanchard’s figure represents an insect whose hind wings are wide at the 
base, as is the case with wmbrata, but not with U. infumata. 
The widest transverse bands on the wings * reach from the nodus (and one to two cells proximal thereto 
behind the principal sector) to the middle of the stigma (Belize g, Altamira ¢, Livingston ¢, Los 
Amates ¢), the narrowest from the first to the penultimate postcubital (Tehuantepec ¢, Crooked 
Island @ ), or from the fourth to the last postcubital (Chapada ¢); or, most extreme, from the level of 
the first to that of the fourth postcubital, behind (and not in front of) the subnodal sector (Vera Cruz @ ). 
These females constitute a partial transition from the banded, or homeochromatic, to the unbanded, or 
heterochromatic, forms, which ordinarily are perfectly distinct, for although many heterochromatic 
females have large parts of the wings brownish-yellow, few of them can be considered as intermediates. 
The brown at the tips of the wings of unbanded females may reach in to the middle of the stigma 
(Sapucay) or even be continued into a paler brown between nodus and stigma (Gualan), 
The presence of brownish-yellow on the base of the hind wings of certain mature or submature females 
(Puerto Cabello, Samana, and especially Acapulco), reaching out almost or quite to the discoidal triangle, 
leads me to think that the broken cotype of montezuma, Calv.®', before me represents merely a very old 
and pruinose female of this extreme of basal wing-marking, where the brownish-yellow has darkened 
with age. ; 
The point on the front wing where the three post-triangular rows increase to four varies even in the same 
locality and time of year (Teapa, January, February), nor is it correlated with size. 
As an instance of variation in size in the same locality, the specimens taken at Teapa in. January furnish’ 
the following dimensions: abdomen, ¢ 23°5-30, 9 26-28; hind wing, ¢ 26-33, 9 30-32 mm: 
While the males affording these two extremes do not differ + in the number of antecubitals on the hind 
wing (9), the larger male departs from the usual specific character by having two rows of cells between 
the short sector and supplementary sector next below, on all the wings. That this increase in density 
of reticulation is not a necessary concomitant of great size is shown by a still larger (abd. 31, 
h. w. 34:5 mm.) male from Teapa, in March, which possesses only the usual single row of cells in 
this area. 
Dimensions.— Abdomen, ¢ 23°5-31, 9 20-30; hind wing, ¢ 26-34°5, 9 25-35; costal edge of stigma, 
front wing 3°2-5°5 mm.

* Two individuals are asymmetricaily banded. A mature male from Morales, Guat., has the band of 
almost maximum width on both hind and left front wings, while the right front wing lacks the band 
completely, although it has some pale yellow in the first and second postcubital areas from nodus to stigma ; 
the venation and dimensions seem normal. A female from Frontera has a dark brown band from first to 
penultimate postcubital on both front and on left hind wings, while the right hind one has a much paler 
brown streak across the entire width of the wing between the levels of the nodus and of the third postcubital, 
the central parts of the cells yellow, as also is an ill-defined distal margin to the brown; here also the 
venation and dimensions are normal. 
7 The smaller male is peculiar in having two submedian cross-veins on both hind wings. 
~ The banded-winged, or homeochromatic, females are designated with a 0 in this list.
