the bars heavy, their plumbeous edges also conspicuous ; admarginal interspaces of 

 hiudwiiig dirty gallstone-yellow. Upper tail 4 — 5 mm., second half the length or less. 



? . Wi/iffg, nppersidc, basal area up to median bars varies from brownish tawny 

 orange to ochraceous tawny orange, being on the whole browner in the specimens 

 from Batjan than in those from Halmahera; the discal, postdiscal and admarginal 

 interspaces paler, being dark orange ochraceous, except the outer portion of the 

 discal interspaces at the postdiscal bars, and the posterior portion of the disc of the 

 hindwing, which are of nearly the same tint as the bases of the wings. Fore- 

 wing : median bars SC= — W forming triangular patches, bars R- — M' generally also 

 heavy, while median bar M' — M- is mostly feebly marked ; of the discal, Inniform, 



barSj the upper three are the heaviest, the others are often fulvous, not black. 



Hindwing with two median bars, only in one specimen (type of brenmis) with one bar. 



Underside : submedian, pro.ximal portion of discal, and admarginal interspaces, 

 buff-colour, median interspace ranch more brown ; all the bars heavy, inclusive of 

 those on the abdominal fold ; jMstdiscal hmiform spots of the hindwing tawny 

 russet ; the discal, black, lunules of the furewing a little more distal in the Batjan 

 specimens than in most individuals from Halmahera. Upper tail 6 — 8 mm long, 

 second 2 J — 3| mm. 



Length of forewing : c?, 39—45 mm.

Ihh. Northern Moluccas. In the Tring Museum from Halmahera, 4 (?<?, 5 9 ? ; 

 Batjan, 5(?cJ, 7 ? ? (W. Doherty, March 1892, 1 ?). 



The tt/pe of latona was said to be from " Timor," but it does not differ from 

 Halmahera individuals ; the figure in P.Z.S. 1865 is rather roughly executed. The 

 specimen was bought, according to the " Register," from Mr. Stevens, together with 

 a number of other Lepidoptera, all said to be collected by Mr. Wallace on Timor. 

 This collection contained several well-known North Moluccan forms which cannot 

 be expected to occur as such on Timor (see Nov. Zool. VI. p. 442). 



The specimens from Batjan are on the whole darker than those from Halma- 

 hera; but the distinctions do not hold good according to the material from both 

 islands submitted to us for examination and selection by Messrs. Staudinger and 

 Bang-Haas. In one of our Batjan SS the black scaling of the upperside is much 

 more extended than in ordinary specimens, the costal margin of the forewing and 

 anterior third of the cell are black, the tawny area of both wings is also less bright 

 than in ordinary iS- 



i\ Ch. latona ombiranus Rothsch., subsp. nov. 



$. As large as the largest specimens of latona latona. 



Wings, upperside. Forewing : black area fully as wide as in the average 



example oi latona latona ; bar D obsolete behind ; median bars R- — M' developed; 



edge of black area not obviously incised upon R^ and BI'. Hindwing : black area 



wider behind than in latona latona, a slight indication of the tawny admarginal 

 intersp)aces M'— SM-. 



Underside darker than in latona latona, the bars still heavier. Forewing : 



the i)ost(iisco-submarginal patches very indistinctly marked, extending close to the 

 discal lunules, admarginal interspaces less yellow than in latona latona, interrupted 

 at the veins ; in one specimen the outer half of the wing minutely striolate 



transversely. Hindwing : admarginal, gallstone-yellow, interspaces more deeply 



concave outwardly than in the allied form ; tails somewhat longer.
