rubl. 5. IV 1913. SPEIREDONIA'i XYLOPHYLLA. By W. Warren. 325 



13. Genus: ^pcirodonia Hbn. 



Tongue present; irons smooth; palpi upturned, stout, the second segment well scaled, the third short, 

 slender, pointed; antennae of cf ciliated; thorax and abdomen smoothly sealed, stout; legs long, without fringes 

 of hairs; wings large and thick, heavily sealed; the forewing marked with a more or less clearly expressed 

 spiral: the body beneath and underside of wings red. Type S. retorta L. 



Seel. II. Antennae of o n minutely serrate and Fasciculate; hindwing with a fold on 

 i n ne rmargi na I area of upper side, containing an expansible fringe of long stiff hairs. 



S. retorta L. (= spiralis F., chimista Kott., jinchuena Btlr., inaequalis Btlr., confusa Btlr) (59d). ? retorta. 

 Forewing olive oehreous clouded with brown: lines dark, curved; the inner edged inwardly with pale, followed 

 below middle by a diffuse darker curved line indented mi vein 1 : median line strongly outcurved above, then 

 inwardly oblique, followed by a dark shade below middle; outer line angled on vein 6, followed by white 

 below middle: subterminal line lunulate dentate, double below middle; terminal line festooned, preceded by a 

 similar one; a large hornshaped blotch in midwing before median line, filled up with dull black, thickly outlined 

 with deep black bounded below by yellowish white and above more narrowly by steelblue; a pale oehreous 

 oblique streak from above it towards apex: deep black lines in the intervals above veins 5 and 6 and often 

 concise white lines above veins 7 and 8; hindwing with a broad blackish anfeniedian band, formed by the 

 widened continuation of the median, the shade beyond it, and the dentale outer line of forewings, the latter 

 followed by a white space: subterminal line pale yellowish, nearly straight, preceded by a broad and followed 

 by a narrow dark brown shade; the two festooned lines as in forewings: underside vermilion red, with dark 

 eellspot and three lines. & Both wings smoky brown to beyond middle, then paler; the lines and the discal 

 mark of forewing all more or less obscured: underside concolorous. This common Indian species occurs in 

 China and Japan; the specimens are somewhat larger than the average, and exhibit two forms of aberration 

 in the ?. both without the paler oehreous shadings: ab. suffumosa Quen. (= Isabella Guen., cohaerens Walk) suffumosa. 

 (60a) is uniform reddish fawn without dusting and dark shades; the other, ab. rubicunda ab. nov. (60b) is rubieunda. 

 tinged with bright fulvous below the grey costal area. 



S. japonica Guen. (60 a). Smaller and brighter than retorta; the & very nearly as strongly coloured japonica. 

 as the 2. and on underside more or less tinged with reddish. China and Japan: the Chinese ?? are paler 

 and brighter than the Japanese. 



S. helicina Hbn. (59 e). Like the last smaller and brighter than retorta; characterised by the yellowish helicina. 

 subterminal line of hindwing being prominently dentate instead of straight, and even. This Indian form also 

 occurs in China and Japan. 



S. martha Btlr. (= aegrota Btlr) (60 b). Forewing pure fawn colour, ranging from pale pinkish fawn martha. 

 to reddish brown, or greyish fawn, often with lower half of median area dark brownish fuscous; lines darker, 

 but rarely prominent: inner line curved, darker dotted on veins, sometimes continuous and plain from costa 

 to middle: median line outcurved from costa to vein 2, then oblique: outer line dotted with dark on veins, 

 followed by a paler line, oblique outwards to vein 6, then inwards; subterminal line pale, undulating, between 

 two dark shades, often all but obsolete; a long deep green crescent on discocellular, sometimes thickened, at 

 others quite slender, or even obsolete; three large green oval spots between bases of veins 2 to 5, sometimes 

 swollen and confluent with one another and with the discal crescent, more often variously divided, or again 

 pale and small and sometimes obsolete; hindwing with inner, outer, and subterminal lines all straight and 

 parallel, the two last outwardly pale-edged; the outer marked by black dots on veins or else dentate lunulate; 

 in the pinker examples the ground colour of hindwing is also pinkish; space between inner and outer lines 

 often darker, and with a middle dark line in between; the palest pinkish fawn coloured examples may be 

 separated as ab. carnea ab. nov. (= ab. 3 Hmps.) (60 b): in the ab. grisescens ab. nov. (60 c) the greyer tints i^se^cens. 

 predominate to the effacement in a great degree of the fawn coloured tinge; Japanese examples are on the 

 average more strongly marked than Chinese, the ?? of which last have a sandy oehreous tinge; — in the ab. 

 signata ab. nor. (= abb. 1 and 2 Hmps) (60 c) the green discal spots are strong, the whole hindwing and signata. 

 innermargin of forewing being generally dark ; — in ab. innotata ab. nov. (60 c) the markings of both wings innotata, 

 are nearly obliterated. Restricted to Japan and China. 



14. Genus: Xylopliylla Hmps. 



Tongue fully developed: frons smooth with a large tuft of hair; palpi obliquely upturned, second segment 

 broadly scaled, third very long, thickly sealed, and somewhat dilated at extremity; antennae of c? simple,
