pied by a large wine-red smear. Hindwing similar, but the whole marginal area wine-red. 42 mm. ■ — ■ Habitat 

 as in the preceding species. 



D. violacea Bull. (48 d). ,^ light purple-grey. Forewing with reddish yellow costa, both wings with violacea. 

 traces of an antemedian line and an oblique sharply marked reddish yellow postmedian luie, which is con- 

 tinued through the centre of the hindwing. 38 mm. — Kashmir. 



D. lilacina Moore. (48 d). Closely allied to japonicn, but the forewing longer, the colour, which varies Hlacina. 

 from silver-grey to light straw-yellow, not quite the same, and the brown transverse Imes narrower and edged 

 with deeper yellow. On the costal margin an antemedian and two postmedian dark transverse spots; before 

 the proximal one of these spots the fu'st transverse line runs almost vertically to the inner margin, while the se- 

 cond begins at the costal margin between the apex of the wing and the distal one of the three spots; both 

 lines are contmued on the hindwing. Forewing with dark submarginal dots. 33 to 41 mm. Sikkim, Kashmir, 

 in September. — simillima Moore differs in that the sharply marked transverse lines are absent, the spots similHma. 

 being also absent or only indicated. Forewong with small brown discocellular bar. Costal area of forewing 

 whitish. Antennae and face golden brown. (^ 38, $ 43 mm. Kashmir. 



10. Genus: Spiea Swinh. 



Forewing with an areole, at the apex of which the short-stalked, or at least strongly approximated, 

 veins 8 and 9 originate, while 7 and 10 are thrown off near the apex of the areole. Middle tibia with one pair, 

 hind tibia with two pairs of spurs. Pectinations of antenna of (^ short and close together. Segments 1 and 

 2 of palpi densely scaled. — Only one species of this genus in our area: 



S. parallelangula Alph. (48 c). Forewing bright light yellow, suffused with brownish at the costal parallel- 

 margin, with a violet tinge ; three slightly brownish parallel transverse lines, one subbasal, one antemedian """" "" 

 and one submedian, which are elbowed almost at right angles in the centre with the point directed marginad; 

 at the apex of the wing a similar oblique streak. Hindwing lighter, more greyish white, and without markings. 

 $ 36 mm. — West China; Amdo district. On the wing in June and July. 



B. Proboscis present. Frenulum absent. 

 (Genera 11 and 12). 



11. Genus: l>eroea Walk. 



Differs in the following particulars from PJialacra, which is otherwise the only genus of tliis group 

 characterised by the presence of the proboscis and absence of the frenulum: Antennae of (J with long pecti- 

 nations, of $ with short ones, wings hyaline or subhyaline, forewing with rounded apex, vein 6 originating 

 from the areole, likewise veins 7 — 11, in the hindwing 8 anastomoses with 7 for a considerable distance. 



D. hyalina Walk. (48 c). Body black with sparse white hair. Wings hyaline, with slight traces of two hyalina. 

 postmedian and one submarginal wavy line, the forewing also with two similar antemedian ones; margmal 

 spots and line indicated. 34 to 44 mm. India, also North-Western Himalayas, Central and Western China. 

 In Sikkim a small, less completely hyaline, form occurs, which may at least be separated as a variety (sub- subhyalina. 

 hyalina var. nov.). 



D. inconclusa Walk. (= maculata Moore). Differs from hyalina in the more distinct and more spot- incondusa. 

 like markings and the white hair onthewmgs; at the costal margin three dark spots, a large double discocellu- 

 lar spot present, in the marginal area two rows of partially confluent spots, the hindwing with traces of two 

 postmedian transver.se bands and 6 distinct marginal spots. ^ 33, $ 36 to 43 mm. Widely distributed in 

 India, also in Kashmir. — phasma Bull. (48 c), from Japan, has darker and more sharply marked .spots, the inner- pluisma. 

 margin of the forewing, which bears two spots in the main form, is without spots, and the hindwing bears 

 markings only at the margua, viz. very small spots. — Leech records the species also from Western China, 

 but does not say whether his specimens belong to the main form or the variety. 



12. Genus : Plialaera Walk. 



Differs from the preceding genus in the following characteristics : Antennae of (^ serrata, of $ widened 

 and flattened, forewing with prolonged sharp apex, vein 6 originating from below the angle of the cell, but 

 7 — -10 from the areole; hindwing nearly rectangular at vein 6. Habitus more like that of the Thvridids. 



P. vidhisara Walk. (= metagonaria Walk.) (30 f). Greyish brown with a reddish tinge and a few black vidhisara. 

 scales here and there, as well as marginal and submarginal black dots. Indications of transverse lines on both 

 wings. Fringes divided by black. (J 28, $ 38 mm. Larva spindle-shaped with broad head, bristly and spinose.
