bles that of the section of Ithomin, to which 7. Hyala, Diasia, &c., 
belong. The colour and markings are the same as in tawny specimens 
of Z). Jemima, but the dark borders form only a very narrow and ill- 
defined edging, and there is no pale yellowish tinge on the disc of the 
wings. The antenns9 are yellowish, with the base black.

89. — Ithomia Hippocrenis. 
S . Exp. 2." Closely allied to I. Diasia, Hewits. (Exot. Butt., Ith. 
f. 28) and belonging to the same section, in which the males have an 
oblong vessel near the costa of the hind-wings filled with long hairs. 
The wings are hyaline with black borders, and tlie fore-wing has a 
black streak across the middle and another over the end of the cell ; 
but the latter in /. Hippocrenis forms a broad spot, very wide on the 
costa, and the two radial nervures are white near the base. The black 
space behind tlie median nervure is much nai'rower and longer than in 
I. Diasia ; the wing is more elongated, and the outer border rounded. 
Beneath : the borders of the wings are all rufous. The antenna^ are 
black ; the collar is red, and the thorax streaked with white.

90. — Ithomia heraldica. 
^ ? . Exp. 2" 5."' Closely allied to I. IpJiianassa (Dbldy. & Hew.), 
but quite distinct from all the local forms of that species. The neuration 
of the hind-wing difliers from that of I. Iphianassa in the middle disco- 
cellular running much less obliquely towards the apex, and the whole 
wing is shorter. The fore-wing differs in being very much broader, 
and in having an upper disco-cellular of considerable length, whilst this 
nervule in /. Iphianassa is so short as to be scarcely visible. 
The fore-wing is blackish-brown, with an elongated diaphanous 
stripe extending from the base to near the hind angle, a second oblique 
discoidal belt consisting of two elongated spots, a third sub-apical belt 
also of three spots, and an apical row of three round spots ; the basal 
stripe and middle macular belt are bordered with dark tawny, which 
colour also occupies the basal half of the costal area ; the other macular 
belt is yellowish, the apical spots whitish. Antennae black, club tawny- 
yellow. Collar dark fulvous, thorax and wing lappets black lineated 
with grey. The hind-wing is reddish-tawny, paler, and diaplianous in 
the middle, and having a dentated narrow black border. Beneath : all 
the dark parts are ruddy-tawny ; fore-wing with five rounded white 
spots at the apex, hind-wing with six white marginal spots, and basal 
streak yellow.
