and Borneo chiefly in that the median band on the hindwing beneath is well margined, with black distally and 
is never placed so near to the fourth and smallest ocellus, but on the contrary there is always a remnant of ground- 
colour between band, and ocellus; the anal ends of the two bands on the hindwing beneath, do not converge so 
strongly at the margin of the wing as is the case in typical specimens. Described by Martin from I I <$<$ am) 
2 from Deli on the north-east coast of Sumatra, also in coll. Fruhstorfer in large numbers from the neigh¬ 
bourhood. of Padang. — fruhstorferi Mart. (93e) may be distinguished, at once from medura, which flies in the fruhstorferi 
same districts, by the ocelli of the hindwing being separated, and decreasing in size and by showing distinctly 
4 small ocelli above the large anal ocellus of the forewing. Yellower, lighter and. smaller than typical argentinei 
and delia, the underside of both wings is without the slight violet gloss (,,purplish” of English authors) which shows 
very distinctly in the forms already mentioned.; the bands are yellow and not brown, but the median, distal, 
angled one possesses a character peculiar to the Javan subspecies, a yellow spur running proximally along the 
margin of the cell, which where the band, leaves the cell accompanies the latter for a short distance, but does 
not reach the discal straight band. That Java with its rich fauna should produce more than one species of 
Erites was a 'priori to be expected. Described from a from South and a $ from West Java; in the Fruh¬ 
storfer collection at Geneva there are further examples; the insects must, however, be rather rare, for in nu¬ 
merous consignments of butterflies from Sukabumi, which 1 have carefully looked, through, there were many 
medura , but not a single fruhstorferi (Martin). 
E. angularis is chiefly characterized, by having the proximal band, of the hindwing angularly broken. 
Apex of the forewing somewhat falcate, in the anal angle of the forewing a large ocellus, and above it along the 
margin of the wing 4 smaller eye-spots, which, however, are wanting in the dry-season form, but may otherwise 
be occasionally absent. — Two branch races: angularis Moore, type from Upper Tenasserim at elevations of angularis. 
3—5000 ft., also known from Pegu, is represented, in my collection by a large series of examples from Perak. 
The dry-season form was found by me at the borders of Siam and Burma, near Kanburi, West Siam, in April. 
pseudofalcipennis form. nov. In this the anal ocellus of the fore wing shows through but weakly above, and pseudofalci 
the under surface resembles the figured, falcipennis (93 e), except that the eye-spot of the forewing with its yel- V ennis - 
low bordering is pointed-oblong and the ocelli of the hindwing are a little longer. — sumatrana Mart. A local sumatrana. 
form of somewhat darker colouring, on the under surface of the forewing, in particular, it closely approaches 
typical angularis from the Malay Peninsula, but it is on the whole a decidedly darker insect; the median, distal 
band, of the hindwing in the $ shows through but little yellow above and. then only for a short distance along 
the apex of the cell, whilst in typical this band, shows yellow on the upperside for its whole length; of the 
5 ocelli of the hind.wing above the second, and. fifth are distinctly the largest in both sexes, whilst in angularis 
from the mainland the fourth and fifth show the largest diameter; the 4 small ocelli placed, over the large anal 
ocellus of the forewing are mostly complete, the upper, costal one is never absent, the fourth, and lowest but 
rarely; in the $ the black marginal lines on the underside of the forewing show quite distinctly, whilst in conti¬ 
nental specimens they are hardly discernible. In North-East Sumatra this species was by far the commonest 
of the three Erites occuring there. 
E. elegans is a pretty species, and deserves its name; from all the other Erites it is distinguished, at a 
glance by the absence of the large anal ocellus of the forewing, on the underside of which are placed 5 about 
equally large, or rather equally small ocelli. Moreover the bands of the forewing, which are very distinctly 
visible on the upper surface, present a characteristic feature in that they run completely parallel and. are distinctly 
convex towards the base of the wing; in all other Erites the proximal band is fairly straight and. only the distal 
one, turning aside from the large anal ocellus, shows a convexity directed towards the base. The discal, proxi¬ 
mal band, of the hindwing is straight, as in all the species with the exception of angularis , but the median, distal 
band is twice bent, the first time about over the middle of the second, subcostal vein, the second, time over the 
base of the upper median vein; only angularis shows exactly the same conformation of this band. In consequence 
of the bend, above the second, subcostal vein the end. of the band converges strongly at the costal margin of the 
hindwing with the end. of the discal, inner stripe and in set specimens is more inclined to meet the proximal 
band, of the forewing than the distal one which really corresponds with it, a condition which is not found, 
in angularis. The $ of elegans is larger than the and has broader wings, the bands of the forewing very 
distinct on the upper surface also; on the upperside of the hindwing the distal band is distinctly yellow and the 
ocelli have broader, brilliant yellow margins; the upper, costal ocellus of the row on the hindwing is no longer 
visible on the upper surface, while in the $ it has not entirely disappeared. A further peculiarity of the 3 middle 
ocelli of the hindwing in the $ consists in their having the black pupils not placed, exactly in the centre, but 
removed eccentrically towards the margin of t-lie wing, so that the eye-spots present a comical, squinting 
appearance (Martin). — Two geographical races may be separated: elegans Btlr. (93 e), just described, from elegans . 
North Borneo, which is represented in coll. Fruhstorfer by 2 examples from South-East Borneo and accord¬ 
ing to Shelford also occurs in Sarawak, where it has perhaps developed a local race, thetis Shelf. — But thetis.
