42S RHYNCH1NA. By W. Warren. 



eel internally ; the base fuscous-tinged along median vein and vein 1 ; abdomen greyish fuscous, with a 

 complete, yellower tinge in $; in the ab. completa Warr. there is no pale scaling along inner margin below vein 1; 

 the inner line is simply curved, and the outer preceded by a thick brown line; the bluish grey scaling of 

 the basal and terminal areas tends to meet along the costa ; hi the hind wing there is some dark scaling at end 

 of vein 1. Perhaps only a form of trigonalis, along with which it occurs. 



arnica. D. arnica Btlr. (72 i). Differs from frustalis in having no pale scaling along inner margin below vein 1; 



the pale grey inner line is simply curved, and the outer preceded by a thick brown line; the whole median 

 area therefore is dark across whig, and not merely a triangular costal space, as in trigonalis and frustalis; 

 the bluish grey scaling of the basal and terminal areas tends to meet along the costa, which is dark only just 

 before outer line; in the pale yellow hind whig there is some additional dark scaling at end of vein 1. Japan 

 and Yesso. Intermediate in size between trigonalis and frustalis. 



opulenta. D. opulenta Alph. (72 i). Forewing fuscous brown; the inner margin below vein 1 pale dull grey; 



the basal area grey speckled with brown; inner line grey, oblique to vein 1; outer line nearly vertical, pro- 

 jecting slightly outwards on each fold, followed by a broad white space with diffuse outer edge, speckled 

 with brown ; the obliquely curved apical streak and the tornal area white thickly dusted with black, the sub- 

 apical cloud and the patch on costa before subterminal line brown; a row of slender dark terminal lunules 

 preceded by a white line; fringe whitish, with three waved grey hues; hind wing pale yellow, with a fuscous 

 terminal border, diffusely edged internally, running to submedian fold; terminal line blackish; fringe pale 

 grey, darker towards apex; abdomen luteous grey. Persia and Bokhara. 



claripennis. D. claripennis Btlr. (72 i, k). Forewing pale chocolate brown; abroad costal stripe dark grey, finely 



dusted with pale; inner line absent; outer oblique, nearly straight, lilac grey, followed by a band of hlae 

 grey speckled with brown; a triangular apical patch of the same colour; subterminal line obscure, lilac grey, 

 plainest below middle; terminal line deep brown, preceded by some lilac grey scaling; fringe lilac grey, 

 with three wavy dark lines ; hind wing orange yellow ; fringe grey, preceded by a slight brown shade ; abdomen 

 yellow; the $ has the basal area of forewing yellower, showing a raised black spot in cell, which is some- 

 times visible also in the $. Japan. 



orosia. D. orosia Cram. (72 i). Forewing pale grey thickly peppered^with fine dark atoms; a little before 



middle of costa a large deep chocolate brown cone-shaped blotch, its truncated apex reaching vein 1, its 

 edges formed by the pale inner and outer lines which become confluent; terminal area towards apex shaded 

 with brown ; fringe grey brown ; hindwing bright yellow, with a brownish fuscous terminal border, gradually 

 attenuated to vein 2; fringe brownish, yellow at anal angle; abdomen and hindlegs yellow. Larva pale green, 

 covered with series of small black tubercles. Found in China, as well as throughout India. 



quadraUs. D. quadralis Walk. (= mollis Swinh.) (72k). A large edition of trigonalis; the inner line curved across wing 



to meet outer line on inner margin, where the grey of the basal area becomes tinged with brown: hindwing 

 bright yellow, with a black border which in very broad at costa, narrowing to a point below vein 2. An 

 Indian species which extends into Japan. 



115. Genus: It liyu china Gum. 



Tongue present; palpi porrect, very long, fringed with long hair above, the terminal segment ob 

 liquely upturned ; frons with a sharply pointed tuft of scales ; thorax and abdomen smooth ; tibiae smooth ; 

 forewings narrow and elongate, with acute apex and oblique termen; hindwings broad and ample; no tufts 

 of raised scales on forewing. Type R. pionealis Guen. 



Sect. II. Antennae of $ subserrate, with fascicles of long cilia. 



Subsect. A. Forewing not exceptionally narrow. 



abducalis. R. abducalis Walk. (72 k). Forewing pale grey or lilac grey, often brownish before an oblique rufous 



brown line from apex to before middle of inner margin, elbowed on vein 4, and sprinkled throughout with 

 blackish scales; a faint curved oblique line from base of vein 1 to middle of cell, beyond a dark dot in 

 cell; two small elark dots on discocellular ; the oblique line from apex is edged with paler; in the pale ter- 

 minal space are two pairs of curved dark lines, often much obscured, but plainest on inner margin; ter- 

 minal line finely rufous ; a row of minute dark subterminal dots ; fringe with three dark grey lines ; hindwing
