Fubl. 20. IV. 1913. PHEOSIA. By Dr. K. Grunbekg. 297 



many and further south the species has two broods, the larva being full-grown in June and October; moths 

 from hibernated pupae are met with very early in the year, of ten already the end of April and in May, the second 

 brood being on the wing in August. Abundant in most districts ; larvae most frequent on old Oaks. 



D. chaonia Hhn. (= ruficornis Auriv.) (45 e). Thorax greyish brown to light grey, abdomen light chaonia. 

 brown. Forewing dark grey-brown, the dark pre-andpostdiscal zigzag bands as in querna, but closer together, 

 particularly at the hind margin, edged with white on the proximal and distal sides respectively; the median 

 area between the transverse bands paler grey, bearing a sharp black luniform discal spot ; in the margmal area 

 a whitish undulate line, which is frequently obsolete. Hindwing light grey-brown. In the southern districts, 

 from southern Central Europe soutliAvard, a uniformly darker form predommates, grisea Turati (45e), m which grisea. 

 the median area of the forewing is also darkened. Another form, which we call ab.lunulaaft.now. (45e), is inter- lunida. 

 mediate between grisea and true chaonia; the whitish colour is restricted to the outer half of the median area 

 beyond the cell and usually interrupted in the centre into a costal and a hindmarginal patch. This aberration 

 likewise belongs to the southern districts. — Europe, northward to Denmark and Livonia, southward to South- 

 ern Italy and Sicily, Dalmatia, Southern Russia, Asia Muior, Armenia; also in Japan. Egg green. Laiwa 

 pale green, with 4 equidistant chrome-yellow longitudiiial lines, of which the 2 dorsal ones are sometimes whitish, 

 the lateral ones on a level with the black-edged spiracles. May to July on Oak, when at rest always on the 

 underside of the leaf along the midrib. Pupa black-bro^\^l, with lighter segmental incisions; in the ground in 

 a cell lined with silk. Moth in April and May, in the South again in August. Even more abundant than the 

 preceding species. 



D. delia Leech (45 d). Forewing grey with a brownish tone, the median area silvery grey, only the delia. 

 costal margm being darker; a subbasal, a pre- and a postdiscal black double band, the first sharply broken 

 in the centre, the second straight, directed obliquely back- and outwards, the third strongly undulate; at the 

 margin a black lunate line. Hindwing olive-brown. — Japan. 



D. circumscripta Bull. Ground-colour of forewing white, densely dusted with brown and grey scales; circum- 

 basal third pale green, distally bounded by a white proximally black-edged undulate line and interrupted by a ^'^^P^- 

 white band which extends from the costal to the hmd margin and is traversed by a red-brown line ; discal spot 

 white; beyond the cell a large olive-green patch, which reaches to the costal margin, extends to apex in the 

 shape of a very irregular streak and bears in its outer half two black dentate lines enclosmg 5 white dart-spots; 

 the outer one of these two lines forms the proximal edge of the apical streak; in the marginal area a strongly 

 curved white submarginal band, the margin itself somewhat darkened. Hindwing greyish brown, with a paler 

 median stripe. • — Japan. 



D. permagna B^^tl. Forewing slate-grey, semitransi^arent ; the base, hind margin and a discal dentate pernmgna. 

 band sap-green ; the usual pre- and postdiscal bands slightly darker than the ground and only feebly developed, 

 each accentuated by a yellow spot at the hind margin ; on the green discal band likewise 2 yellow spots ; disco- 

 cellular vein black, beyond the cell a white costal spot, a larger one at the apex; margin dark browai spotted 

 with yellow. Hindwing greyish brown, with a slightly curved M'hitish median band which ends at the anal 

 angle in a large sulphur-yellow spot which is edged with black proximally as well as distally, at the outer black 

 edge a small patch of blue scales. — Japan. 



D. eximia s-pec. nov. (45 d). Exceptionally bright-coloured and large for this genus. Ground-colour eximia. 

 of forewing white, somewhat toned do^vn by dispersed black scales ; a large blackish bro^vn basal patch does 

 not quite reach the base and extends a little beyond the white prediscal band; the postdiscal band, which is 

 less promment, is contiguous with a large dark subapical patch which occupies the whole costal area to near 

 apex; the dark discal spot distmct; near the margin a black lunate line. Hindwing dark greyish brown. — ■ 

 Japan. 



D. tnandschurica Oherth. (49 b). Thorax and forewing bluish grey. Forewing with a whitish basal spot, mayidschw 

 the prediscal band indicated by a whitish spot at the costal and hind margins, the postdiscal band also only "''''■ 

 represented by some pale spots; fringe light-spotted. Hmdwing yellowish grey. — Manchuria (Sidemi). 



18. Genus: Pheosia Hhn. 



Antennae pectinated to the apex, the branches rather long in ^, short in $, the basal segment of ^ 

 with a tuft of hair. Palpi very short. Proboscis vestigial. Eyes naked; ocelli absent. Forewmg long and narrow, 

 apex rather pointed, distal margin strongly oblique, forming an obtuse angle with the hind margin, the latter 

 curved, bearing a tooth of scales in the centre, vein 6 from upper angle of cell together with stalk of 7, 8, 9, 10; 

 no areole. Hindwing broad, the anal angle slightly prominent, veins 6 and 7 on a long stalk. Thorax with long 

 and dense, but smooth hair, the legs likewise long-hairy, the hair on abdomen shorter. Hmd tibia with mid- 

 and end-spurs. — Larvae elongate-cylindrical, smooth and as glossy as porcelain, bearing only dispersed minute
