GAILEUS.— OESOXOBA. 53 



(particularly the secondaries); a grey-edged dark brown discal line, and a zigzag grey 

 submarginal line : secondaries with two or three scattered fulvous dots. Expanse of wings 

 39 millim. 



North-east Himalayas (Lidderdale) . 



Garseus costatus, sp. a. (Plate CXIV. fig. 1.) 



Curiously like Ellopia in pattern and Plutodes in general coloration. Wings above 

 rufous-brown, covered with minute pale striations : primaries with the costal and external 

 borders very irregularly and unequally lemon-yellow ; discoidal cell on the edge of and below 

 the costal border irroratcd with plumbaginous scales ; a large irregular apical grey patch 

 bounded on two sides by the yellow borders and between them by a diffused streak of 

 ferruginous; its upper edge (where it is bounded by the costal border) irroratcd with plum- 

 baginous scales; an ill-defined brownish streak across its centre: secondaries paler than 

 primaries, with the apex and apical fringe yellow ; a few marginal subapical plumbaginous 

 scales: head, collar, and shoulders lemon-yellow; remainder of body above pale brown. 

 Under surface brownish grey ; with sulphur-yellow borders, as above : primaries with a 

 narrow oblique blackish streak from the origin of the second median branch to near the 

 external angle; a nearly transverse blackish subapical band connecting the two yellow 

 borders : secondaries with a bifid subapical blackish patch, followed by an ill-defined smaller 

 patch of blackish scales. Expanse of wings 46 millim. 



Darjiling (Lidderdale). 



This beautiful species, although different in pattern from the other known forms of 

 Gareeus, agrees structually with it. 



ORSONOBA, Walk. 



Orsonoba pallida. (Plate CXIV. fig. 5.) 

 Orsonoba pallida, Butler, Ann. ij' Mag. Nat. Hist. ser. 5, vol. vi. p. 125. n. 28 (1880). 



Allied to 0. delta, but much smaller, the outer margin of the primaries much less 

 sinuated, not at all so below the third median branch ; altogether paler, the prevailing colour 

 being creamy white; costal half of primaries grey, the markings very nearly as in 0. a 

 all the bands testaceous, the oblique dashes across the costal border of the primaries blackish 

 browu : secondaries with the hyaline spot at the end of the cell elongated, transverse, 

 margined with testaceous instead of black. Expanse of wings 48 millim. 



North-east Himalayas (Lidderdale). 



The true position of the genus Orsonoba must at present remain doubtful ; though its 

 general resemblance to the females of Hyposidra renders it possible that it has been correctly 

 placed in the Ennomidae, it nevertheless possesses features characteristic of the Erosiidse
