SOUTH-AFEICAN BUTTERFLIES. 
more hairy head and palpi, less robust thorax, origin much nearer to 
discoidal cell of third subcostal nervure of fore-wings, larger fore-legs 
in ^, and much longer middle and hind legs in both sexes. 
The limits of Euryphcne^ Aterica, said Harma — all purely Ethiopian 
genera — are by no means well defined, and authors appear of late years 
to have referred newly-discovered species to them somewhat at random. 
Aterica, founded by Boisduval in 1833, is oldest in date, and its 
type was A. Eahena, Boisd., of Madagascar. Uu7'iphene (sic) was pro- 
posed, but not defined, by Boisduval in 1847 (Appendix to Dele- 
gorgue's Voyage dans VAfrique Australe^ p. 592) for a South- African 
butterfly ( E. cmrulca^ Boisd.) brought from Natal ; and it was West- 
wood (oj;. cit.) who first gave a diagnosis of Euryiohene, adding to E. 
ccerulea the Fabrician species, So2)Jms and Ahsolon, with Eoriclea, Drury, 
and seven others referred with doubt to the group. Among the nume- 
rous species since added to the genus, such differing forms as E. Comus, 
JVivaria, and Forphyrion, of Ward, and E. Soemis, Phantasia, Ammis, 
and Eoralice, of Hewitson, seem ill associated with E. ccerulea and its 
allies ; and those of them which prove not to be better placed with 
Aterica (or some possibly with Harma) will probably require new genera 
for their reception. Harma — also characterised by Westwood in 1850 
— is a more homogeneous group in general facics, but, as its founder 
pointed out, variable in neuration ; and in nearly all respects its struc- 
ture agrees with that of Aterica. 
E. ccerulea would appear to be a very rare butterfly, as no example 
has to my knowledge occurred in any collection made in Natal or the 
neighbouring regions since the time of Delegorgue's visit. It is, 
however, a species of small size and dark colouring, and if, like some 
of its congeners in Western Africa, it frequents the shadiest parts of 
the woods and is not very active, it would easily escape observation. 
No other Euryphene is recorded from Southern Africa, nor does the 
genus appear to be represented in Eastern Africa, all the species except 
E. ccerulea being natives of Tropical Western Africa to the north of the 
Equator.

Habit and size of Guineensis} — Deep-blue, as in Veronica, Cram. ; 
near hind-margin of hoth wings a row of oval spots rather darker than 
ground-colour, succeeded by a marginal streak of the same hue. Basal 
portion of wings, as far as middle, of a darker hue than ground-colour; 
and on this darker portion, in f ore-wing, are two or three annular spots 
of paler blue, situated transversely between costa and median nervure. 
^ This seems to be only a manuscript name of Boisduval's, and is by Westwood {Qen. 
Diurn. Lep., ii, p. 286) doubtfully given as a synonym of E. Ahsolon (Fab.)
