Ferepay.—Species of Butterfly belonging to the Family Satyride. 3038 
convex on the upper side with the apex curled back; underside of outer 
margin of club deep yellow, extending partly down the shaft. 
Kyes, naked. 
Labial palpi, of moderate length, contiguous, slightly diverging towards 
the apex, obliquely elevated in front of the head, densely clothed with hairy 
scales, three-jointed, middle joint long, third joint very small. 
Body, sooty-black. 
Fore-legs, sooty-black, rudimental, very small, rather smaller in the 
female than in the male; tarsi not jointed, two rudimental claws on the 
tarsi of the female. 
Middle and posterior legs, sooty-black, ungues double. 
Wings, sooty, velvety-black, shot with rich bronzy-brown; fringe same 
colour. Expanse, Mas., 19-21 lines; Fem., 24-25 lines. 
Upperside—Primaries, entire ; costa and hind margin convex; apex and 
anal-angle (the latter considerably) rounded ; a submarginal patch (slightly 
paler than the ground colour) from three to four lines broad near the costa, 
and narrower towards the anal angle. Within the patch are several con- 
fluent black ocelli with small silvery-white pupils. There are generally five 
of these ocelli, three of which are in a line drawn from the costa (near the 
apex) towards the middle of the inner margin; the pupil of the ocellus 
nearest the costa being very minute and in some specimens obsolete, and 
the ocellus farthest from the costa being the largest of all the ocelli. The 
two other ocelli are respectively situated in the areolets between the third 
subcostal, externo-medial, and sub-externo-medial nervures, and are im 
some specimens followed by a third ocellus, detached from the others and 
situated in the areolet formed by the sub-externo-medial and interno-medial 
nervures ; these latter ocelli form a sub-marginal row. 
' Secondaries, orbiculate-triangulate ; hind margin slightly denticulated, 
but denticulation hardly perceptible ; discoidal cell closed; color same as 
the primaries, but without any markings. 
Under side, colour and markings of the upper side repeated, but rather 
paler and more richly bronzed. fone e

Habitat, Western range of mountains, Province of Canterbury, New 
Zealand; also, mountains at Lake Guyon, Province of Nelson, New 
Zealand : 
This interesting butterfly is found at a great altitude, frequenting the 
slopes formed by the débris from the disintegration of the mountain peaks. 
No vegetation is scen on these slopes, the débris being composed of emall 
angulated stones continually slipping down the incline. The butterfly is 
generally seen flying in the hot sunshine, close to the surface of the stones,
