322 NYCTIPAO. By W. Warren. 



9. Genus: Xyctipao Hbn. 



Tongue well developed: frons smooth; palpi upturned, moderately scaled, the terminal segment long; 

 thorax clothed with hairs, without crests; pectus woolly; all the tibiae spined; cell of forewing l / s , of hindwing l / 5 ; 

 hindwing of <? not aborted, with neuration normal as in ?. Type N. crepuscularis L. 



Sect, 1. Wings of cf with androconia. 



albicinctus. N. albicinctus Koll. (=rivularis Westw.) (59 a). Forewing metallic purple fuscous, the whorl-shaped 



stigma large, placed on a greenish patch with some brick red scales in the centre; the black head with a 

 blue patch, two white specks, and some white scales on it; a curved ochreous white narrow subterminal band, 

 angled above vein 3; veins towards termen and the fringe ochreous white, more strongly in ¥ than cf; 

 hindwing with the subterminal band angled above veins 6 and 3; the fringe and veins white. The forewing 

 of cf is clothed with velvety androconia on upper side as far as outer line except at costa, and is altogether 

 browner, less purplish than the ?. An Indian species recorded by Leech from Kwei-chow, Western China; 



obnubilate, sometimes, in ab. obtiubilata ab. nov. (59a) of the cT, the outer pale line is attenuated and partially obscured 

 by brown suffusion. 



pilosa. N. pilosa Leech (58 d). Forewing fuliginous brown, suffused, especially in outer half, with purple; 



inner, median, and outer bands darker, indistinct; a large chocolate brown ocellus outlined in black, with blue 

 scaling on the inner edge of the black comma-shaped pupil; beyond it a fine sinuous white line, which does 

 not reach the inner margin; hindwing with two darker bands and a sinuous white line. The forewing of cf 

 on upperside is clothed below cell and discoidal stigma with rough androconia to beyond middle; the hindwing 

 with rough androconia throughout, except a narrow space along termen. Occurs in Central and Western China. 



glaucopis. N. glaucopis Walk. (= prunosa Moore) (58 d). Forewing smoky olive brown, shot with purple; differs 



from pilosa in the subterminal line being almost evenly curved, and not irregularly sinuous, broad and white 

 below subcostal vein, less distinct below vein 5; in the hindwing this line, running nearly parallel to termen, 

 is marked with two broad white lunules betwen costa and vein 6, then with narrow linear ones ; on underside 

 of forewing this line consists of large white lunules throughout. A $ in the Felder collection from Kashmir, 

 probably authentic; as the species occurs in the N. W. Himalayas, as well as in Sikkim and Assam. In this 

 species the forewing of the cf is without androconia, but the hindwing on upperside is clothed with rough 

 androconia to near outer line, except at inner margin. 



Sect. II. Wings of cf without androconia. 



crepus- n_ crepuscularis L. (= ephesperis Guen. part nee Hbn.) (58 d, 59a). cT Forewing dark brown; inner 



line sinuous, indistinct; the whorl brown with black edges, its head bilobed and accompanied by a few blue 

 scales; beyond it a black line, angled beyond cell and oblique to near base of inner margin, with a broad 

 white or fulvous band beyond it; outer line sinuous, black; subterminal black, irregularly lunulate, the lunules 

 containing white marks: terminal area grey, with a large triangular costal patch before apex; hindwing with 

 pale basal band, followed by a black line; a waved median line with long pale hair beyond it; a black 

 lunulate subterminal line, inbent between veins 3 and 6, with white patches on it; terminal area fulvous 

 brown except at apex; ? greyer, with less contrast of colour than in the <f, but the nearly straight outer 

 line is often whitish. The above is the common form of the species occurring in India and many of the Malay 

 Islands, also in Kashmir; the Japanese and Chinese forms, which also occur in the Loochoo islands, are 

 laetilia. darker with the outer white band more prominent; in the ? of ab. laetitia Btlr. (59b) which is smaller, the 

 ground colour, instead of being greyer, is fuliginous fuscous; the outer straight line is white, sometimes 

 swollen into a narrow band with a ragged outer edge; the pale outer area of the curved median stripe is 

 replaced by dull fawn or fuscous; the white submarginal lunules are shallower and more conspicuous; the 

 cfcf, though not prominently different, are also darker and duller than in the type form, hi the more eastern 

 Malay Islands two other forms of the species occur, both with dark ??, one without, the other with a broad 

 ephesperis. while band with ragged edges; this last is ephesperis Hbn.; Guenee in his description of epliesperis, of which 

 he thought he had two ??, confounds the two forms; his example from Japan, from which his description 

 seems to have been made, being Butler's laetitia, while that from Amboina was the true epliesperis. 



clavifera. N. clavifera Hmps. (= leucotaenia Guen., part). $ Forewing fuscous brown; basal area with a slight 



purplish grey gloss; inner line dark, indistinct, oblique below ceil; discoidal mark an inverted comma with 

 bilobate head, defined by black, and its head by silvery blue scales; some white and rufous scales in inner 

 part of centre; median line black, denned externally by while, excurved from costa round and below discal 

 mark, then indistinct and oblique to inner margin; an oblique pure white outer band, with dentate outer 

 edge, arising below costa ami narrowing above; a wedge shaped white patch below costa before apex with
