1886.] RHOPALOCKRA FROM THE SOLOMON ISLANDS. 34^ 



few minute yellowish atoms : secondaries not tailed, margins 

 scolloped ; a broad transverse outwardly-sinuated greenish creamy- 

 white fascia, its inner margin touching, but not extending into, 

 discoidal cell ; a conspicuous orange-red oval spot at anal angle. 

 Underside black : primaries with four white apical spots, and a 

 whitish streak at base of cell : secondaries with a row of seven 

 orange-red marginal spots, the one at anal angle being much the 

 largest, and above these a series of six lunules composed of pale- 

 bluish atoms ; indentations pale yellowish. 



Exp. 144 millim. 



Hab. Ugi, Solomon Islands. 



This fine Butterfly belongs to the Erectheus group. It was 

 tolerably common at Ugi in June 1883, but difficult to catch on 

 account of its powerful flight, and its habit of keeping in the thick 

 forest, where it could not he easily followed. I saw several of what 

 I believe were the females of this insect ; they were much larger 

 thau the males, of a dark brown, and with more white across the 

 wings. 



I have named this species in honour of Admiral James E. Erskine, 

 who commanded the Australian Squadron at the time I was on the 

 Station. 



Papilio bridgei, n. sp. (Plate XXXIV. fig. 2.) 



Male. — Upperside deep black, appearing greenish black in certain 

 lights: jjrimaries, a marginal band of eight somewhat square-shaped 

 pale greenish-white spots curved inwards at the apex, the apical 

 spots being small and indistinct ; base of cell and apex dusted with 

 a few whitish atoms : secondaries not tailed, scolloped ; a broad 

 transverse outwardly-dcntated pale greenish-white fascia, its inner 

 margin enclosing lower part of cell, and its upper portion running 

 between costa and subcostal nervure nearly to base. Underside 

 black : prityiaries, subcostal nervure inwardly bordered by a narrow 

 whitish streak from base to near middle of cell ; a few whitish 

 atoms at apex : secondaries, a marginal row of seven pale pinkish- 

 orange spots, the three nearest the apex small and obscure, the one 

 at anal angle large and nearly square-shaped ; above these a row of 

 seven ill-defined lunules of pale-bluish atoms, the one at apex nearly 

 obsolete ; indentations conspicuous, white, crescent-shaped. 



Exp. 1 18 millim. 



Hab. Treasury Island, Solomon Islands. 



This is another fine species, and also belongs to the Erectheus 

 group. It was not uncommon, but, like P. erskinei, frequented the 

 thick forest and was difficult to capture. I only obtained one, a 

 very perfect example. I saw a larger insect, of a dark brownish- 

 black hue and with larger spots and fascia, which was probably the 

 female of this. 



I have named this species in honour of Captain Cyprian A. G. 

 Bridge, who commanded H.M. ship ' Espiegle ' during her long and 

 interesting Commission of nearly four years, a great portion of which 

 time was speut among the islands of the Western Pacific.
