excluded. Thus P. albifimbria Warren (1896) and P. marginata Warren (1899) 

 should undoubtedly be assigned to Comostolopsis ; P. rubripunctata Warren 

 (1909) would be better placed in Chloeres, while the actual affinities of P. caerulea 

 Warren (1893) and P. cosmetocraspeda Prout (1916) are not yet quite clear. 

 There remain the following species : P. deliciosa Warren (1896), founded on a 

 single example from the Natuna Islands and probably a race of the species 

 next in order, i.e. P. pyrrhogona W'alker (1866), of S. India and Ceylon, with 

 subspecies turgescens Prout (1917. — Khasi Hills) ; P. marginata T. P. Lucas 

 (1888), of Queensland and the Tenimber Is. ; P. augustata Prout (1917.— 

 Loyalty Is.) ; P. cornuta Warren (1896), distributed from the Malay Peninsula 

 and the Philippine Is. to the Louisiade Archipelago and the Solomon Is. ; P. 

 viridula Warren (1903. — British and Dutch New Guinea) ; P. rhodometopa 

 Prout (1913. — Mt. Goliath, Central Dutch New Guinea), possibly a form of the 

 following ; P. ruficeps Warren (1906. — British and Dutch New Guinea). 



The species now described extends the range of the genus eastward into 

 Polynesia. It belongs to the group containing P. ruficeps and P. rhodometopa 

 — green, with brighter red borders and crown — which is connected by P. viridula 

 with the two bluer species, P. pyrrhogona and P. cornuta. 



6. Pyrrhorachis rhodoselas, sp. n. 



(3\ 19 mm. Near P. ruficeps Warren (1906) and P. rhodometopa Prout 

 (1913). Body, as in the former, with the red dorsal streak not interrupted with 

 green at base of abdomen ; its colour still brighter, without pale central dash 

 on thorax posteriorly, but with an indistinct dark dot in the centre of each 

 segment. 



Fore wing with costal margin brighter red than in the allied species, and 

 less densely dark-irrorated ; red distal border intermediate in width, but 

 widening appreciably at tornus, and near its proximal boundary marked through- 

 out with small, deep violet-grey interneural spots ; a crescentic yellow cell-mark, 

 scarcely noticeable with the naked eye. Hind wing similar, except costally. 



Fore wing beneath with costal margin pale pink to whitish, at extreme 

 edge proximally bright rosy, wanting the black admixture seen in the allied 

 species.

This specimen will be figured, in colour, on a plate which will be published
