170 SOUTH-AFRICAN BUTTERFLIES. | 
of wing, ratlier broad, truncate at extremity. Hind-ivings large, rounded, ' 
somewhat prolonged inferiorly ; costa variable in convexity ; hind-margin I 
entire, or (in Cleodora) moderately dentate ; costal nervure usually ex- ! 
tending to apex, but in Lcda ending at some distance before it ; first 
subcostal nervule much arched, given off far before end of cell ; disco- 
cellular nervules very oblique, — lower one more than twice, or nearly 
thrice, as long as upper, and strongly sinuated ; discoidal cell more than 
half as long as wing, more or less acuminate inferiorly at extremity; 
abdominal channel formed by inner margins complete, but not deep. 
Legs short, slender ; femora hairy inferiorly for more than half their 
length from base ; tibiae set with short appressed silky bristles, and 
sparsely and finely spinulose beneath, — their terminal spurs very fine ; 
tarsi rather thickly spinulose. 
Abdomen rather long, deep, arched, clothed with long silky hair at 
base. 
I do not find ground for following Mr. Butler in limiting Eronia 
to E. Cleodora and the Leda group," but would retain in it the other 
African species, only separating from it the Asiatic and Austro-Malayan 
species ( Valeria^ Cram., Hipina^ Fab., &c.), whose much longer abdo- 
men, antenna3, and fore-wings, as well as their totally different pattern 
and facies, amply distinguish them.-^ 
Eronia in general structure and neuration is near Teracolus^ differ- 
ing, however, in having the subcostal nervure of the fore- wings five- 
(instead of four) branched, much smaller and blunter terminal joint of 
palpi, and gradually formed, not flattened, club of antennae. In its 
robuster body and gradually clavate antennae, and in outline of wings, 
it exhibits some approach to Ccdlidryas (one species, E. Buqiietii, in tint 
and marking has quite the aspect of the pale species of that genus). 
The seven or eight species which Eronia contains are good-sized 
butterflies, and present remarkable differences in pattern and colouring, 
the $ being in some instances highly variable and quite unlike the $. 
The type of the genus is E. Cleodora^ in which the sexes are alike 
white or yellowish, with a sharply-defined black hind-marginal border, 
and have the under side of the hind-wings creamy-yellow bordered and 
spotted with mixed brown and silvery-grey. E. Leda (on which Bois- 
duval founded his genus Bryas) is vivid-yellow, with a brilliant-orange 
apical patch in the fore-wings, and looks like a magnified Teracolus 
Auxo ; and the Madagascar E. Lucasi, Grandidier, is white with a 
lemon-yellow apical patch. The males in E. Argia and Thalassina are 
greenish-white and greenish respectively, with black borders, but their 
females are coloured with ochre-yellow and orange-red in imitation of 
certain species of Picris and Mylotliris. Both sexes of E. Euquetii are 
alike of a plain greenish-white, with a blackish apical hind-marginal 
^ The (5 s of this group are bluish or bluish-white, with black border and neuration, and 
the 9 s, by a modification of these markings, closely mimic various species of Danais. (See
