368 B ATRAC HART A; ERYGIA. By W. Warren. 



virens. B. virens Btlr. (= japyx Stgr) ((37 h). Forewing pale grey green, speckled with black scales; lines 



double filled in with green mixed with whitish; the inner nearly vertical, indented on subcostal vein and 

 dentate outwards below it, rectangularly angled outwards on median vein; its inner arm deeply indented be- 

 tween submedian fold and vein 1 ; space between subbasal and inner lines fdled up with a chocolate brown 

 fascia, outwardly black-edged, as far as submedian fold; its inner edge reaching vein 1 narrowly; outer line 

 lunulate dentate, oblique outwards to vein 4, where it is acutely angled, and toothed at 6, below 4 insinuate 

 inwards, followed by a chestnut brown fascia, inwardly black-edged and broad to vein 5, paler and narrow 

 below: the veins across its broad upper half black; subterminal line green, interrupted and confused; a row 

 of green Iunules with black centres along ternien, continuous in costal half of wing, interrupted by the thicken- 

 ed brown vein ends in the lower; fringe chequered brown and green; orbicular stigma a white spot; reniform 

 whitish, subquadrate, the discocellular green at its centre, with a black dot at each end; a dark grey median 

 shade running parallel to outer line; hindwing dull greenish grey with the veins and the lunulate dentate outer 

 line dark; a dull brown terminal border from apex to vein 2, darkest and broadest at apex; terminal Iunules 

 black, edjjed inwardly with green and below vein 2 with white; fringe brown rayed and tipped with green. 

 Japan, Yesso, Amurland. 



staudingoi. B. staudingeri Leech (= ? niveola Motschl.) Forewing pale bluish green, crossed by several 



conspicuous, black, wavy-dentate lines; a black brown patch on costa towards base, a larger brownish patch 

 in apical area, with a smaller one below it at anal angle; stigmata white with black outlines; hindwing pale 

 fuscous, with two dark median lines and a broad diffuse submarginal band. Described from a single ¥ from 

 Gensan, Corea. - - Distinguished from B. virens Btlr. by the black transverse lines, white stigmata, and brown 

 patches. 



15. Genus: Batracliarta Walk. 



Tongue present; irons with slightly projecting scales; palpi obliquely upturned, the second segment 

 thick, reaching vertex, the third long, slender, blunt; antennae of cf with sessile fascicles of cilia; abdomen 

 elongate, slender, tufted on first two segments of dorsum; mid and hind tibiae with a fringe of long hair on 

 upperside; forewing elongate, the costa straight; apex rounded; termen obliquely curved; inner margin sinuate ; 

 covered with strigose shading and suffusion; the usual lines indistinct; veins 8 and 9 anastomosing to form 

 an areole; vein 5 in both wings from just above 4. Type B. obliqua Walk, from Borneo. 



cossoides B. cossoides Walk. (67 h). Forewing deep red brown with numerous dark curved strigae; the black 



areas without any white dotting as in irrorata Hmps.; basal black area limited by an oblique deep black line 

 from median vein to inner margin; outer line forming two conspicuous teeth outwards above and below 

 median vein, the upper one acute; the black shade preceding narrow and not connected with the basal 

 area except along costa ; subterminal line black, close to termen, and swollen, as in irrorata, into tooth-edged 

 blotches on both folds; veins towards termen reddish, vein 1 red beyond inner line; hindwing brownish, with 

 veins and cellspot darker; fringe pale ochreous. Closely allied to irrorata Hmps. but rather smaller; the type 

 from Borneo; a ? in Tring Museum from the Khasia Hills; recorded by Leech from Kiukiang. 



16. Genus: Erygia Guen. 



Tongue developed; irons smooth; palpi slender, obliquely upturned, the second segment hardly reaching 

 vertex, the third pointed; antennae of cf ciliated'; metathorax with large tuft; basal segments of dorsum with 

 slight tufts; hind tibiae and tarsi dotted with long hair; forewing elongate triangular; the costa straight; apex 

 produced; termen oblique, crenulale; inner margin sinuate, the anal angle with slight tooth of scales. Type 

 E. apicalis Guen. 



apicalis. E- apicalis Guen. (= exempta Walk., squamiplena Walk., geometroides Walk) (67 h). Forewing dark 



brown with red intermixed on a pale ground; with numerous indistinct and interrupted inwardly oblique wa- 

 ved lines; a blackish band before inner line from cell to inner margin; black markings on costa towards apex 

 and before anal angle; hindwing fuscous with reddish patch near middle of termen. The species, which 

 occurs from India to Australia, is mentioned by Leech from Japan, Corea, and W. China. Usta Walk., with 

 median area clearer, seems to me a distinct species.
