chestnut scaling in the outer area of the forewing beneath is also deeper than 

 in 0. wildei, and the genital armature agrees with that of phalaris. 



The subapical obUque bar in the cell of the forewing does not form a direct 

 contmuation of the brown vein-streak R', but ends below the lower angle 

 of the cell. On receipt of more material this may prove to be an mdividual 

 distinction only. 



2. Oxyambulyx substrigUis tattina subsp. nov. 



(J. Linea submarginaU alae anticae minus cm vata infra indistincta, armatura 

 genitali diversa. 



Long. al. ant. 55 mm. 



Hab. Battak Mts., North-East Sumatra (Dr. L. Martin), one male. 



Forewing conspicuously shaded with ohve-green, especially between the 

 antemedian lines and again between the discal ones ; the subapical costal 

 triangular ohve-green patch broader and less obhque than in 0. s. substrigUis ; 

 the marginal band less widened before middle ; the black submarguial line 

 not accompanied on the proximal side by a pale line, but instead by a diffuse 

 ohve-green shadow ; the subbasal round spot drab in this specimen. Hind- 

 wing more tawny than in the male of 0. s. substrigUis. 



On the underside the forewing almost uniformly reddish tawny in the area 

 proximal to the grey marginal border ; the latter less wide before middle than 

 in O. s. substrigUis, and the submarginal Une boxmding it not distinct, being 

 diffuse and but httle darker than the area proximal to it. 



The apex of the ventral process of the harpe almost symmetrical, the apical 

 margin of it shghtly incurved ; distally of the long pointed upper process indica- 

 tions of teeth. Inside-rod of penis-sheath broad, not pomted. 



3. Oxyambulyx semifervens celebensis subsp. nov. (text-fig. 3). 



(J. Ahs angustioribus, antica margine exteriore in medio recto, macula 

 diffusa fusca subapicaU magna, linea submargmaU supra et subtus ohvaceo nigra. 



Long. al. ant. 39 mm., lat. 12 mm. 



Hab. Maros, South Celebes, July 30, 1906 (Dr. L. Martin), one male. 



In shape and colourmg recaUuig 0. subocellata reld.(1874). The forewing 

 has two subbasal grey-bordered spots below the cell as in semifervens Walk. 

 (1864) ; the discal markings are distinct, as in many subocellata, and the ohvaceous- 

 black subapical cloud also reminds one of that species ; the submarginal hne, 

 which is ohve-black both above and below, is distinct to R' ( = vein 4 of Herrich- 

 Schafifer) and is curved as in 0. s. semifervens ; the distal margin is straight 

 from below apex. The anal angle of the hindwing is less produced than m 

 subocellata and shghtly more than in semifervens. 



On the underside the forewing bears blackish lunules on the disk ; the 

 grey marginal band is as broad as in semifervens. Distal margin of hindwing 

 blackish ; this narrow band indented at the veins on the proximal side. 



As in semifervens the harpe without the long upper process found in suh- 

 ocellata ; the ventral process long and narrow (text-fig. 3), very different from 

 that of 0. s. semifervens.
