EROSIA. 103 



numerous dark strigoc. Fore wing with an indistinct, highly-concave brown band from just 

 before the middle of costa to middle of inner margin ; a distinct postmedial band, concave to 

 second median ncrvulc, then convex to inner margin ; a dark lunulate submarginal line. 

 Hind wing with waved and curved brown antemedial and postmedial bands ; a lunulate dark 

 line from the first subcostal tail to near anal angle. Underside whitish, with dark strigse. 



Nearest in markings to D. obscwraria, but whiter, and with the hands more regular. 

 D. obscuraria has the apex of fore wing acute, the tails of hind wing longer, and the outer 

 margin emarginate between the tails and also towards anal angle. Also near D. lilacina, 

 which has the apex of fore wing somewhat acute ; the outer margin of hind wing emarginate 

 between the tails, and the bands bent outward towards the anal angle.

 Erosia unicauda. (Plate CL. fig. 21.) 



Expanse S inch. 



Male. iVpex of fore wing rounded, as also the outer margin of hind wing except for one 

 slight tail at first subcostal ncrvulc. Wings pale purplish grey, irrorated with dark scales. 

 Fore wing with costal area darker, a large oval spot on it with first brown, then a pale 

 border, one third from apex, and extending to lower end of cell ; a smaller dark subtriangular 

 spot, with pale border, on the inner margin two thirds from base ; a series of blackish sub- 

 marginal lunules with pale borders inwardly, and obsolete towards outer angle. Hind wing 

 brown ; antemedial and postmedial curved narrow bands ; some indistinct pale-bordered 

 lunules from tail to anal angle. Cilia of both wings black. 



Nearest in markings to E. binotata, but quite distinct in shape and coloration. 



Erosia longlpennis. (Plate CL. fig. 20.) 



Expanse § inch. 



Male. Fore wing long ; apex rounded ; inner margin more excised than in the other 

 species of the genus : hind wing with costa excised towards apex ; outer margin with a slight 

 tail at first median, and a more pronounced one at the subcostal nervules, and highly irregular 

 in outline. Both wings smoky black : hind wing with an indistinct darker medial band. 



This species may be closer to the genus Gathynia, the hind wing is more excised and 

 the tail longer. 



Erosia fulvilinea. (Plate CL. fig. 19.) 



Expanse g inch. 



Male and female. Apex of fore wing slightly acute; hind wing with pronounced tails at 

 first subcostal and second median nervules. White : fore wing with some yellow strigse near
