TWO NEW SPECIES OF BHOPALOCERA FROM THE 

 SOLOMON ISL.\NDS. 



By TilE HON, WALTER ROTrT8< 'IIILD. 



LATEL'i' I liavp received some butterflies collected by Carl Ribbe on the island of 

 Bougainville, among wliicli are two striking novelties. 



1 . Prothoe ribbei sp. nov. 



This species in size approaches nearest to P. hnjardi Godni. I'C: ?>alv., P. Z. !i., 

 p. 7o8 (1882), from New Ireland, but is a most distinct species. 



Male. — Uppersule : black. Forewings crossed bv a transverse creamy-white 

 baud, which is narrow between the discoidal nervules and widens suddenly at the 

 upper median branch, but does not become so wide as in allied species. Hindwings 

 also with a transverse creamy-white band, which is of almost uniform width, and which 

 is inwardly nearly straight, except at flie extremities; basal third of abdominal 

 margin white. 



Underside: blackish brown. Forewings with a submarginal row of creamy 

 patches, of which those in the apical region are more distinct ; beliiiid the co.sta are 

 also two indistinct spots ; within the cell are a varying number of minute w'hite spots, 

 from five to seven. Hindwings with a submarginal row of golden yellow markings, 

 which are linear, except the two before or behind the upper median branch ; inside 

 this row stand eight pale blue irregular half-rings, inside which again there is a band 

 of thin huffish transverse streaks; on the basal third there are some minute white 

 spots. 



Female. — Similar to the w/'^e; larger, browner. The baud on the forewings is 

 much narrower, macular, or is even obliterated, except a spot near the inner margin ; 

 that on the hindwings also narrower ; abdominal margin unicolorous. Below, the 

 submarginal spots to the forewings more distinct. 



Expanse of wings : cJ, 4'2 inches = 107 mm. ; ¥, 4-5 inches = ll.J mm. 



II(di. Bougainville Island, Solomon Islands (Carl Ribbe le;/.; 6, ¥. types in 

 coll. Jtibhe; S. ? ill Mils. Tring). 



2. Delias schonbergi >p. no\. 



Male. — Uppernide : white, base powdered with black .scales. Forewings, in the 

 apical region, with a row of six white spots inside which the disc is grev ; apical 

 margin black. Hindwings with a narrow black margin. 



Underside: foi-ewings with basal third yellowish ; outer half bla<-k, the black 

 area entering the apex of the cell, including six well-defined white subapical 

 markings. Hindwings with basal half yellow ; outer half with a snlimarginal row 

 of six large pear-shaped scarlet patches, each ciri'led with white; disc between 

 costal margin and lower median nervule and the outer margin black. 



Female. — Uppe^-side : grey. Forewings with outer half black : a suliapical row 

 of white sjiots, of which the anterior ones are large, the posterior ones small.
