.still darker than the granulata- type to yellowish ochreous igualensis in all kinds of transitions, yet each of the 
forms may occur predominantly or exclusively at the two typical habitats, so that both the names may be 
maintained. 
B. monava Dyar. The submarginal band being broad in the preceding species is linear in monava. 
Ground-colour of both wings olive grey, strewn with straw-colour at the base, with dense dark reticular lines. 
The forewing with a small triangular hyaline spot in the cell. The band behind it dark, broad at the costal 
margin. The distal margin narrowly dark. The large hyaline spot on the hindwing is indented outside. The 
whole marginal area behind it dark. Submarginal line indistinct, interrupted. 1 from Zacualpan (Mexico). 
B. liypothyris Dyar. The body is more slender than in the other species. Wings broad, bronze black. 
Forewing with a few yellow spots at the costal margin and in the centre of the wing below the cell. Similar 
spots in the dark median band of the hindwing. Both wings with large hyaline white discal spots, that of 
the forewing oval, that of the hindwing rounded quadrangular. Nothing is mentioned of a submarginal line 
on the forewing; it will be covered by the dark ground-colour. Violet beneath, the forewing with 2 black bands 
and scattered streaks. 15 mm. 1 from Guerrero. 
2. F o r e w i n g w i t h o u t a w h i t i s li hyaline discal spot. I f s u c h a spot 
is present on the h i n d w i n g , it is not quite transpare n t. 
B. dixozoiia Dyar. Body partly dark greyish brown. The forewing yellowish with fiery red spots. The 
basal area fiery red. brown at the costal and inner margins, the interior band behind it, beginning below the 
costal margin. Reticular lines fine, dense. The main band oblhpie, broad, united with a first band from be¬ 
fore the middle of the costal margin and a second band close at the end of the main band, forming a fork of 
it. Hindwing with a broad basal band. The hyaline spot narrow, despatching a basal ray from the lower edge. 
Exterior band broad, running obliquely to the anal angle. 22—24 mm. Mexico. 
D. siipsa Drc. (173 a). Body and wings reddish brown, the transverse bands somewhat darker. The 
interior band and the main band of the forewing are somewhat widened in front, the submarginal band un¬ 
interrupted, parallel to the margin. Hindwing with a luniform white spot without a prolongation to the base. 
Under surface lighter. 30 mm. Panama. I consider nipsa to be an oculatana without a spot in the forewing. 
The indistinct dark marking is the same in both the species. I have one specimen each at hand with and 
without a hyaline spot on the forewing, from Chiapas (Mexico); they would therefore have to be two species 
from different groups. 
B. angulisola Dyar. Ground-colour yellow with some copper red. Forewing with broad violettish 
brown bands; the interior one broad at the costal margin, filled rather dark. Submarginal band interrupted, 
the anterior part terminating into the costal margin near the apex, the other part forming a spot above the 
anal angle. Hindwing dark at the costal margin and in the basal band. The discal spot is angular, divided. 
The centre of the wing with fine reticular lines, broadly light, without intense lines. 25 mm. 1 specimen from 
Panama. - - Three somewhat different specimens probably belong yet to this species. One specimen each from 
Costa Rica and Mexico has a darker hindwing; in the former the wing is uniformly dark, in the latter the 
light median stripe is narrow. The third specimen, from Peru, is more intensely copper red on the hindwing, 
the costal margin not darker. Both the hyaline spots are larger. Dyar himself thinks that angulisola may be 
identical with the following thyridina Fldr., which may be correct. 
D. thyridina Fldr. (173 a) was formerly combined with speculifera Sepp, but according to Warren and 
Dyar they are different. The ground-colour is brownish ochreous, not orange red, the costal margin in both 
wings is broader dark than in speculifera. The reticular lines are finer, forming pale spots between the veins. 
The cellular spot of the hindwing is shaped as in oculatana. its 2 parts being united in the $, separated in the 
rj. The dark band extends before the hyaline spot, not behind it. On Feeder's figure in his work “Reise der 
Novara", pi. 117, fig. 20, the anterior part of the submarginal band on the forewing extends near the distal 
margin, and not into the costal margin as in angulisola. This would be only a slight difference. According to 
1 § thyridina from the Chanchamayo, which is before me by the kindness of Dr. Jordan, the figure is wrong. 
The submarginal band is exactly like that described in angulisola. thyridina was described from Guiana, it 
occurs also in Colombia, Peru, Bolivia. 26—30 mm. 
In the following species as far as flagrata inclusively, the submarginal band of the forewing ends at vein 3 
or 4, or it is linearly continued at most. The median band of the hindwing is forked, a feeble branch extends to the 
anal angle. 
D. speculifera Sepp (= aequalis Wkr.) (173 b) shows the hyaline spot on the hindwing large, undivided. 
The median band on the forewing terminates pointed at the inner margin. The species is never recognizably 
figured. The original work shows an orange yellow insect and a reddish violet one. The main band on the 
forewing is extremely broad at the costal margin, narrower at the inner margin. An interior band and a basal 
one are very thickly painted. The costal margin is not darkened. The dark brown band on the hindwing 
encloses the large hyaline spot. 32 mm. Florida, Tropical America. — Hampson takes flagrata Wkr. and 
thyridina Fldr. to be synonymous with speculifera. According to Warren, they are 3 different species. There 
are 5 specimens before me, which may be speculifera, because they do not fit to the descriptions of the other
