544 MR. H. W 
12. Ithomia Antisao. 
Ithomia Sao, Hewitson, Exot. Butt. Ithomia, f. 110, 111. 
This form requires to be distinguished by a separate name from J. Sao of Hubner, 
although it be only a local variety of it, on account of its wings being less clear, the 
nervures tinged and bordered with reddish, and the hind-wing border having a reddish 
stripe within it. The true Sao of Hubner, of which I examined the typical example in 
Dr. Boisduval's collection, has very clear wings, sharply defined nervures, and the hind- 
wing border wholly dark brown. I did not find this in the Amazon region, the 
whole of the examples collected agreeing with the figs. 110, 111 of Hewitson. On the 
Upper Amazons it is an extremely abundant species. 
With this species commences the tendency to determination of the hind-wing neuration 
towards the costa. In the tf the upper radial is placed as a branch of the subcostal near 
the apex, and consequently there is no upper disco-cellular nervule. In the 2 the upper 
radial is connected with the cell by means of an upper disco-cellular, in the same way as 
in the typical Ithomia I. Flora and its allies. 
13. Ithomia Tuctjna, n. sp. 
J 2 . Expanse 1" 9"'-2" 4'". Closely resembles in shape, markings, and neuration 
Ithomia Zerlina (Hewitson, Exot. Butt. Ithomia, f. 94-96). Differs in colours. Fore 
wmg hyaline : above, the entire margin evenly bordered with dark brown, which colour 
also forms a short oblique belt running from the costa across the end of the cell ; the 
hyaline part brownish, with a large spot in the middle of the cell, a crossbelt beyond the 
cell, and a row of elongate spots between the nervures, near the margin, light yellow ; the 
costal stigma, with the nervures crossing it, and the base of the upper radial light 
yellow. Beneath, the same, except that the outer margin, from the costal stigma to 
the hind angle, is orange-coloured, edged with black, and that there are two white spots 
at the apex. 
Kind wing ; above, more broadly margined with dark brown, except on the abdominal 
edge ; the whole basal part of the disk, extending to the abdominal margin, with the 
nervures traversing it, light yellow ; an elongate spot over the lower radial, also, same 
colour. Beneath, the same, except that the margin is orange, edged with black, and that 
there is a marginal row of five white spots set in black semicircles. 
Body black ; thorax spotted with white ; abdomen yellow beneath. Antenna? black ; 
club orange-yellow. 
Abundant in humid parts of the forest, at St. Paulo, Upper Amazons. The hind-wing 
upper radial is totally wanting in the c? . 
14. Ithomia Salapia, Hewitson. 
Ithomia Salapia, Hewits. Exot. Butt. Ithomia, f. 15. 
The collar and wing-lappets are rufous, and the antennal club yellow ; otherwise it 
very closely resembles I. Primula.
