GADIRTHA; BLENINA. By W. Warren. 



of subterniinal black spots; hindwing yellow; a black terminal band, broad at apex, extending along costa to 



near base and narrowing off to termen at vein 2 ; the band is shot with blue ; the veins across it are blue, some- 



indica. times swollen at middle to form a band; — the subsp. indica Roths, is smaller, both wings shorter; the terminal 



band of hindwing narrower, the deeper yellow ground colour bluntly angled above middle, instead of being 



javanica. curved; the blue gloss both above and below much reduced; — subsp. javanica Roths, is still smaller; the terminal 



border of hindwing as broad as the yellow area, and limited by an evenly vertical curve; the dorsal spots of 



philippi- abdomen quite small; — the subsp. philippinensis Roths, differs in the larger size of the subterminal spots of 



nensis. forewing. The type from China has longer narrower wings; but this form occurs also atDarjiling, N.India; the 



subsp. indica being confined to the South. 



6. Genus: Gadirtha Walk. 



Tongue present, but small; frons smooth; palpi upturned, strong; the second segment thick, densely 

 and closely scaled, slightly roughened in front, the third as long as the second, smoothly scaled, spatulate; 

 antennae of <$ with minute sessile fascicles of cilia, the shaft thickened basewards; thorax and abdomen smoothly 

 scaled ; legs hairy ; the fore tibiae with broad thick pad of hair, the proximal segments of fore tarsi also hairy ; 

 forewing narrow, the apex blunt, termen well rounded oblique below vein 3, with a strong crenulation be- 

 yond submedian fold; slight raised tufts of scales along both folds. Type G. inexacta Walk. The single species 

 is large and stoutly built. 



inexacta. G. inexacta Walk. (= bufonia Fldr. = tinctoides Snell.) (53 b). Forewing pale grey, freckled and 



striated with darker, the costal half suffused in the g with reddish brown, in the $ with pale lilac brownish or 

 greenish ; lines slenderly black, irregularly angled and interrupted, the inner preceded by a large fuscous costal 

 blotch and met below median vein by a black streak from base; costa with two small dark spots in middle 

 and 3 more towards apex, more or less conjoined to form a patch; submargmal line pale, waved, preceded and 

 followed towards anal angle by irregular dark patches ; orbicular stigma round, grey or brown ; reniform with 

 a very fine black outline, rounded internally, externally with a sharp tooth at middle, the centre usually darker; 

 marginal lunules dark grey; hindwing dingy fuscous, darker in the^. This widely spread insect, found through- 

 out India, Burma, in Java, New Guinea, and N. Queensland, is recorded also from China: Chusan Ids., Hong- 

 kong, Ichang, Changyang; and in the Tring Museum is a dark grey $ from Japan. These Chinese and Japanese 



uniformis. examples, like some from the Khasias, belong to the ab. uniformis ab. nov. (=ab. 1 Hmps.) (53b), with uniform 

 greyish forewings and fuscous brown hindwings; the Japanese specimen, moreover, is decidedly smaller than 



impingens. the average ; • — the form impingens Walk. (53 b) $3 only, has the forewing suffused with purplish brown, and 

 the tornal area greyish white from middle of termen to middle of inner margin ; in the New Guinea form the 

 hindwing is ochreous white, the terminal area only suffused with fuscous brown narrowing to a point at tornus ; 



papuensis. — ab. papuensis ab. nov. (= ab. 3 Hmps.). ■ — ■ The larva is sait to be one of the most common in Southern 

 China and to resemble that of Demas coryli, with the skin and tufts of hair greenish yellow; it makes its 

 cocoon on the trunks of trees, and is as difficult to distinguish as that of Cerula furcula; the pupa is flat, 

 and moves its abdomen very quickly, so that the anal segments, playing upon a row of silken strings, like 

 those of a guitar, spun by the larva at the lower end of the cocoon, emit a noise somewhat resembling, though 

 fainter, the chirping of Cicadae. The above facts were communicated by Dr. Seitz who also sent the cocoon 

 with the apparatus for inspection. 



7. Genus: ISleiiiiia Walk. 



Tongue present; frons smooth; palpi upturned, with appressed scales, the third segment long and slender, 

 blunt ; antennae of $ shortly ciliated ; thorax and abdomen smoothly scaled ; dorsum with more or less distinct 

 tufts at base; forewing short and broad, shouldered at base; termen vertical to 4, then sharply oblique; the 

 areole long and narrow; the retinaculum bar-shaped in the^; slight ridges of raised scales on inner, median, 

 and outer lines, and on discocellular; hindwing with rounded termen; vein 5 from lower angle of cell. Type 

 B. donans Walk. 



Sect. IV. Palpi of <$ normal. 



senex. B. senex Btlr. (53 e). Forewing pale to dark blue green, varying according to the denseness of the 



dark grey and fuscous dusting; the $ always dull dark grey green; lines black, wavy; the inner line outcurved 

 to near middle of inner margin; the outer, nearer to inner line than usual, slightly excurved round cell and 

 dentate below middle, approaching inner line on submedian fold; a slight dark cellspot; submargmal line pale, 

 flexuous, preceded by a dark green line, which above anal angle is marked with black, forming a black lunule on 

 submedian fold with a black dash before it ; hindwing brownish luteous or fuscous with dark outer line separated 

 by a paler band from the broad blackish terminal border ; fringe luteous grey, dotted with dark ; the hindwing 

 of the $ is darker than in the $. Two forms in the <$$ may be differentiated from the simple typical form; 

 jasoiata. ■ — ab. fasciata ab. nov. (53 e) has the median area diffusely filled in with fuscous greenish extending often to the
