PAPILIONIDAE. 

 1. Troides chimaera spec. nov. (PI. 111. f. 25. ?). 



?. Black. Head smaller than in tlie allied species. Eye without white 

 border. Red colour of breast restricted, forming two patches which are not 

 extended downwards to coxae as in tithoiins and paradisea. Abdomen shagfry, 

 each segment with a yellow aj)ical band all round. Legs black. 



Wings, upjjcrsidc black. Forewing : subfalcate, the distal margin being 



shallowly emarginate ; vein SC from angle of cell as in paradisea, stalk SC^° 

 about as long as the upper two cross-veins ; a transverse, sinuous cell-patch, an 

 interrnpted row of discal spots, another of postdiscal ones, and sharply marked 



fringe-spots white, shaded with black. Hindwing similar in shape to that of 



paradisea, but niore deeply scalloped, rather woolly pro.ximally ; a spot in cell 

 and the disc white shaded with black, the discal area externally tinged with 

 yellow : seven black spots within this area, the first and the last connected with 

 the black area, the other iive isolated ; white fringe-spots distinct. 



Underside similar to upper. Forewing : spots larger, purer white, discal 



series complete from SC to (SM'), the postdiscal spots more or less edged with 



grey, some diffuse grey scaling from postdiscal spot SC — SC^ outwards. 



Hindwing : cell-spot and proximal portion of discal area purer white, distal 

 portion purer yellow. 



Length of forewing : 103 mm. 



Hah. Owgarra, north of head of Aroa River, May 1903. 



This very peculiar insect is in neuration nearest to paradisea, but differs 

 from all species known in the banded abdomen. 



2. Troides goliath. 



Ondthoptera arrimna, Felder ; aberr. ? goliath Oberthiir, Et. Eiit. xii. p. 1 (1888). 

 Ormthoptvra goliath id., l.r. xi.x. p. 1. t. 4. f. 19 (1894). 



Dr. Pagenstecher, in Ja/ir/j. ]!fass. Ver. Nat. Ivi. jx 77 (1903), has published 

 an article on this fine insect. We agree with Dr. Pagenstecher perfectly in his 

 conclusion that <joliath, supremus { = schoenbergi), elisahetkaereginae, and titan, are 

 names applying to one species only. But we mast make a reservation. The 

 specimens from British New Guinea are certainly different from those obtained in 

 other parts of the island. We possess of this southern form {goliath titan) two 

 ? ? from the Aroa River, one collected by Weiske and the other found by Meek. 

 Both specimens differ from those known from Dutch and German New Guinea 

 in the forewing bearing only a few very small white markings, and in the posterior 

 black discal spots of the hindwing being smaller. 



We have no specimens of goliath from German New Guinea, but possess one 

 $ and two ? ? from the Dutch portion of the island. The S came from somewhere 

 about Geelvink Bay. It was contained in a collection made by natives or half-castes. 

 This specimen agrees in colour well with the second one of Pagenstecher. It has 

 a forewing of 82 mm. length. (We mention incidentally that it is erroneous to 

 say that the green jiosterior aroa of the forewing is powdered with black. Tlie 

 green scales belong all to the upper layer. It is a black area powdered witli 

 green.) 



Our two ? ? from Kapaur, Dutch New Guinea (IJolierty)— the one caught in 

 January, the other in February 1897 — differ from one another in the size of tlu'
