 grey band: on Primula acaulis. 



E. accipiter Fldr. (14 h). Forewing dull purple brown: costal area pale green, more broadly at accipiter. 

 base and beyond cell; lines and stigmata tinged with vinous; stigmata black -edged, the reniform with 

 curved green central line: submarginal line preceded below costa by two black sagittate marks; hindwing 

 pale yellow with broad fuscous border; fringe yellow: head and tegulae ochreous, streaked with brown and 

 sprinkled with black. — Yatong, Tibet. Recorded originally from N. \Y '. Himalayas. 



38. Genus: Triphaena Hbn. 



Funis smooth: tibiae hairy; only the mid and hind tibiae spined; palpi hairy, the terminal segment 

 short; forewing long, with subparallel margins, as in Epilectu: antennae of d* ciliated. A genus of stoutly 

 built moths, with strongly developed legs. 



Type T. interjecta Hbn. 



T. efflorescens Btlr. (= jankowskii Obertlt.) (14 h). Forewing mossy green in basal two-thirds, then efflorescens. 

 purplish: veins lilac grey, black-spotted; stigmata green, with dark centres and black edges; cell black; a 

 large diffuse white blotch beyond cell; hindwing orange, with broad black border; costal and inner margins 

 and a submedian streak from base more narrowly black: cellspot large and black; fringe yellow. Restricted 

 to E. Asia, occurring in Amurland and Japan. 



T. semiherbida Walk. (= decorata Btlr.) (14h). Forewing pale green, mixed with lilac- or purplish- semiherbida: 

 grey, especially on inner and outer margins and along the veins; upper stigmata rufous and green with 

 black lateral edging; a black dagger-shaped mark below costa before submarginal line; hindwing orange 

 with broad black border; the inner margin from base brownish; cellspot large and black. Occurs in 

 W. China and Japan ; originally described from N. India, where it is widely spread. 



T. fimbria L. (= domiduca Hufn.) (14i). Forewing ranging from pale ochreous and rufous in the $ fimbria. 

 to redbrown and olivegreen in the d*; ochreous d"c? are rare; markings slight in the ?, strong in the d"; 

 inner line dark; outer and submarginal pale; upper stigmata large, pale-edged, often touching; a dark 

 costal blotch before submarginal line: hindwing and fringe orange, with a very broad black border; the 

 pale rufous forms are known as ab. rufa Tutt (14 i), and the deep redbrown forms as ab. brunnea Tutt; — rufa. 

 the dark olivegreen cfcf are solani F. (14i), while the paler more ochreous green specimens (? cfcf) brunnea. 

 are ab. virescens Tutt; — a rare and handsome form of the a 71 called by Tutt ab. brunnea-virescens has solani -

the deep redbrown and olivegreen tints combined. — Generally distributed throughout Europe, and f, nmnea .' 

 occurring in Algeria, Asia Minor, and Armenia. — Larva reddish-ochreous , paler at the sides and spotted virescens. 

 with brown; dorsal line paler; a dark pale-edged bar across the 12" 1 segment; spiracles pale on dark spots; 

 feeds on Primula, and probably other low plants. 



T. interjecta Hbn. (15a). Forewing greyish rufous, sometimes darkened with fuscous; lines and interjecta. 

 stigmata a little darker, often very obscure; hindwing orange yellow with a broad marginal black border; 

 costal and inner margins , a submedian streak from base, and the cell blackish ; fringe yellow. Found 

 throughout South and Central Europe and in Britain. — Larva pale ochreous with black dots; the lines 

 pale, with darker edges; on various low plants. 



T. janthina Schiff. (15 a). Forewing purple and brown; costal edge, like the head and shoulders, pale janthina. 

 ochreous; upper stigmata edged with ochreous; claviform absent; a chestnut red costal blotch before sub- 

 marginal line: hindwing orange yellow with a broad black outer border, the base and inner margin suffused 

 with blackish. The species agrees with T. fimbria in distribution. - - In ab. rufa Tutt (15 a), the whole rufa. 

 forewing is bright rufous; on the other hand the form latimarginata Rob. (15a), occurring only in the lati- 

 Harz Mts. , is deep purple black, with a very broad black border in the hindwing; in ab. flavomaculata marginata. 

 Spider the orange ground is reduced to a rounded blotch at centre. — Larva greenish ochreous, the dots ^°' l[ata 

 black: dorsal line pale: a series of oblique dorsal and lateral marks, sometimes obscure, and two black- 

 spots on 1*2"' segment; on various low plants. 



T. undosa Leech (15a). Forewing grey brown, darker in parts; median area black above median undosa. 

 vein, with waved lines below it: the stigmata black-outlined; submarginal line whitish, waved, preceded by 

 a black costal patch; hindwing dark fuscous, the fringe ochreous yellow. Found only in Japan. 



39. Genus: Eueretagrotis Smith. 



Characterised by the rough-haired pectus and femora; second segment of palpi broadly fringed in 

 front with hair, the third depressed ; antennae of <f , in the palaeai*ctic species, with pedicellate or tuberculate 

 fascicles of cilia.
