60 EUROIS; CERASTIS. By W. Warren. 



leucocyma. A. leucocyma I [iimps. Forewing red brown, with dark dusting towards base; the veins black; a 



black streak below base of cell; stigmata outlined in black; the claviform narrow, emitting a black streak 

 to outer line: orbicular wedgeshaped, oblique; reniform with whitish lunule on outer edge; submarginal line 

 white, wavy, accompanied by black streaks; hindwing dull white, tinged with brown externalh'. — ■ Des- 

 cribed by Hampson from - 2 ?? only, from Nubra, Kashmir. 



31. Genus: Euvois Hbn. 



Frons smooth: palpi porrect, hairy, the terminal segment not elongated; foretibiae hairy, without spines. 

 Type E. prasina F. 



prasina. E. prasina F. (= herbida Hbn., egregia Esp., mixta Hate, herbacea Gum.) (14a). Forewing olive 



green, variously tinged with dark green or blackish; a green-tinged creamcoloured or whitish blotch between 



the renifonn stigma and outer line; stigmata dark green edged with black; inner and outer lnies black, 



conversely edged with white, or whitish green, or concolorous; hindwing fuscous with a paler fringe. 



jaspidea. Generally distributed through Europe and Northern and Central Asia to Japan. — In jaspidea Bkh. the 



pallida, pale patch beyond the reniform stigma is wanting and the stigmata are blacker; ab. pallida Tutt represents 

 the extreme pale form, the whole wing being whitish green, in which the white patch beyond the reniform 



suffusa. is absorbed, and the bnes and shades are distinct only in the costal half of wing; — ab. suffusa Tutt is 



a rare form in which the green tints are superseded by red brown with the area round the stigmata blackish; 



albimacula. — in albi macula Hornmz., from the Bukowina, the groundcolour is a mixture of dark and light grey, 



lugubris. with the patch beyond the reniform clear white, or filled in with grey; — lugubris Petersen from Esthland 

 is dark brownish grey with only slight traces of green or white colouring. — Larva purplish brown, with a 

 pale dorsal line intersecting a row of blackish dorsal blotches; spiracular line pale, with a dark edge 

 above: on various low growing plants. 



virens. E. virens Btlr. (14a). Forewing bright moss green, speckled with dark; the veins lilac-grey, also 



dark-mottled; costa with black spots; lines green, black-edged; stigmata Avith green edges, their centres and 

 the cell area blackish; submarginal line preceded by blackish wedgeshaped spots; hindwing dull blackish, 

 with white fringe. — Found in Amurland, West China, Japan, and Corea; originally described from N. India. 



32. Genus: Cerastis TV. 



Agrees with Mythimna and Orthopia in having the fore tibiae without spines; the frons smooth; 

 pectus and abdomen hairy, the latter flattened. The imagos of the European species appear in spring, 

 the larvae feeding in the summer and passing the winter as pupae. 



Type C. rubricosa F. 



Section I: Antennae of r? bipectinatecl. 



leucographa. C. leucographa Schiff. (14b). Forewing pale brickred; the median and narrow terminal area brown; 



upper stigmata prominently pale ochreous grey with dark centres; teeth of outer line very long, the veins 



dark beyond; hindwing dirty grey; veins and a diffuse terminal shade darker. Occurs in France, Germany, and 



lepetitii. Switzerland, and in Britain, Denmark, and Russia in the North; also recorded from Amurland. — lepetitii Bsd. 



suffusa. is wholly redbrown, without the pale submarginal band, the stigmata without pale edging; — suffusa Tutt 



is an extreme form in which the dark median shade is expanded to cover the whole forewing, making it 



rufa. deep blackish red; — rufa Tutt is pale bright red, much paler than the type. — Larva green or reddish, 



with darker mottling; dorsal and subdorsal lines pale; a row of dark lateral oblicme stripes; spiracular line 



pale greenish; feeds on various low plants during summer time, hybernates as pupa, and emerges in spring. 



pailescens. C. pallescens Btlr. (= lata Stgr.) (14b). Forewing dull red brown; basal area above vein 1, the 



semicircular orbicular and costa above it pinkish ochreous dusted with grey; reniform stigma redbrown with 

 inner edge pale and outer partly black; cell velvety black; lines indistinct; the submarginal pale; hindwing 

 grey, the fringe pink. Amurland and Japan. 



caelebs. C. caelebs Stgr. (14 b). Like the grey form of sobrina Bsd., but the o" has strongly pectinated 



antennae. Kuku-Nor and Amdo, Tibet. 



Section II: Antennae of c? serrate and fasciculate. 



rubricosa. C rubricosa F. (14b). Forewing red brown, varied with grey, sometimes with a purplish-brown 



tinge; stigmata grey with fine dark outlines; a broad angled median shade; lines all starting from black 



costal spots; hindwing fuscous grey; fringe grey. Generally distributed in Europe, except Spain, and found 



rufa. in W. Siberia ami W. Turkestan. — The form rufa Haw. (14b), the usual British form, is almost wholly
