20. Ercheia latistria, sp. u. 

 ? . — 55 mm. 



Head and body coloured as in sliarply marked dubia, the 

 wliite segmental lines of abdomen rather stronj^. AVinjjs 

 shaped as in dubia, or M'ith the termen slightly more 

 crenulate. 



Fore wing uith the coloration and essential markings 

 of dubia and cyllaria ; probably equally variable ; in the 

 unique type the prominent dark markings are the " semi- 

 circular" costal patch between submedian line and apex, 

 the costal end of antemedian and median lines, and a thick 

 black longitudinal streak behind cell and proximal part of 

 IVP from base nearly to postmedian line, here crossing M' 

 and continuing in cellule 2 to termen ; postmedian line 

 moderately distinct; subterminal line weak; broad but ill- 

 defined terminal clouding between R* and tornus. 



Hind wing blackish fuscous, with clean white markings, 

 similar to those of qxiadriplaga, Walk., but broader. 



Underside as in the most sharply marked forms of dubia, 

 the basal part of both wings being predominantly white; 

 cell-spot of hind uiiig smaller than in most dubia. 



Gilolo, 1901. 



Perhaps a local race of dubia, in which case quadriplaga 

 and cyllaria may also belong to the same protean species. 



21. Achcea cyanobathra, sp. n. 



S . — 47 mm. 



Head and body dark brown, the abdomen darker dorsally ; 

 pectus and hair of femora and tibiae partly more ochreous ; 

 bases and tips of spines and narrow rings at ends of tarsal 

 j iints also pale. 



Fure wing dark brown with very strong purple gloss (in 

 the proximal area somewhat darker and much bluer, in the 

 narrow terminal area wanting) ; a faint curved pale subbasal 

 line from costa to S]\P ; antemedian line 6 mm. from base 

 at both margins, almost straight, slightly waved, little paler 

 than th.e ground-colour ; a weak dark spot representing the 

 orbicular stigma ; reniform nearly as in intercisa. Walk., 

 but less conspicuous on the darker ground ; postmedian line 

 feeble, apparently formed as in leucopera, Druce, the veins 

 beyond it with slight pale dashes ; a dark double sub- 

 terminal line slightly nearer the termen than in leucopera 

 and wanting the apical ornamentation of that species ; a 

 crenulate dark terminal line ; fringe with slender pale line 

 at base and a less sharply defined one in middle.
