172 RHOPALOCERA AFRICA AUSTRALIS. 



Both the figure and description referred to are of the female 

 of this species; but no doubt can be entertained, on comparing 

 the insects, that the specimens for which Mr. Hewitson pro- 

 posed the name of Ephira, are really males of Ethalion. 



This species appears peculiar to South Africa, and has, as yet, only been 

 taken at Natal. I am nearly certain that I once noticed the male insect on 

 the borders of a wood at Knysna, on December 23rd, 1858. The Butterfly 

 flew twice from the edge of the wood over the hill-side rising above it, and 

 attracted attention from its very black appearance, as it rapidly passed me. 

 1 can think of no other species resembling it both in size and colour.

Black, glossed with metallic deep-Hue ; and with transverse 

 rows of blue spots. Fore-wing : blue brightest at base ; 

 beyond discoidal cell, a little below costa about middle, is 

 the first of an obliquely-transverse row of four blue spots, 

 tending towards anal angle, and meeting an outer, transverse, 

 slightly-waved row of similar spots, extending from costa 

 near apex to inner-margin not far from anal angle ; hind- 

 margin varied with a row of conspicuous, dull-ochreous, 

 lunular marks. Hind-wing : blue gloss brightest near base ; 

 near hind-margin, two rows of sub-lunular blue spots, the 

 outer row parallel to hind-margin, the inner, more irregu- 

 lar ; two rows of dull-ochreous lunules along hind-margin ; 

 two short, black, tails, at extremities of first and third median 

 nervules, respectively the former the longer of the two. 

 UNDER-SIDE. Shining, dull-olivaceous grey ; with blue-black, 

 white-edged, transverse striae, and dull-yellow spots. Fore- 

 wing : three transverse striae in discoidal cell ; one just 

 beyond it ; two short striae beneath cell one above, the 

 other below, third median nervule ; a dentate, externally 

 white-edged, blue-black stripe, from first median nervule 

 beyond cell, almost to inner-margin near anal angle ; the 

 outer row of blue spots, on the upper-side, represented by 

 dull-yellow, larger spots, increasing in size near inner-margin, 

 the two last being internally black-margined, and externally 

 with two blue-black, violet-edged spots. Hind-wing: some 

 transverse striae, near base, enclose a space of dull-yellow;
