136 EUPROCTIS. By Dr. E. Strand. 



of the inner margin to the cell -n-ith an only slightly distinct obliqxie stripe formed of black specks, with- 

 out diseocellular spot. tS 30, $ 35 mm. The type-form has black spots at the apex of the forewing; this is 

 interna, not the case in intensa Bull, from Japan. In the latter the dark median band is moreover slightly more 

 distinct, and is'divided at or shortly before the centre into two narrow bands almost reaching the costal margin. 

 bipundi- Amur, Ussuri, Corea, China, Japan. — ab. bipunctigera Strand ab. nov. In o and $ there are in the costal 

 ''^"" half of the marginal area of the forewing two black dots, usually mth a lighter edge, forming a trans- 

 verse row, two or three mm apart and only half as far from the margin; these spots, to judge from the speci- 

 mens before me, arc more or less distinct in most cases. Yokohama and Noith Cliina (Museum Berol., 

 type from Yokohama). 



stramiiiea. E. straminea Leech (23 a), from West and Central China, is light yellow, face whitish, palpi dark, 



abdomen light gi'ey-brownish, anal tuft white variegated with orange (rj') or brown ($): Foremng light yel- 

 low, with a dark median band which is interrupted by the veins, forked before the median vein, not reaching 

 the costa; no apical or submarginal spots. Hindwing silky white. Underside white; forewing with an inter- 

 rupted dark subcostal stripe and a dark smear on vein 3. ^ 33 — 40, $ 42 — 48 mm. Allied to E. flava intensa Btlr. 



niphonis. E. tiiphonis Butl. {= squamosa Butl., raddei Stgr.) (21e, f). ^ grejash smoke-colour, forewing above 



densely coveied with black and yellow scales, costal margin broadty leather-yellow, hkewise the outer 

 margin, which is sparsely scaled ^vith black, diseocellular spot black. Hindwing smoky grey. Head and 

 collar ochreous, antenna blackish, thorax light leather yellow, abdomen browTiish. Underside of ^vnngs 

 bro-vvn, costal and distal margins partially leather-j'ellow. 36 — 37 mm. $ (21 e) ochreous; forewing above 

 leather-yellow with a broad reddish smear between the cell and the inner margin, not reaching the base, and 

 black diseocellular spot ; base white, with black subbasal spot. Hindwing with black diseocellular spot and 

 straw-coloured underside. 47 mm. Japan, Corea, China, Amur, Ussiu-i district. — Fixsen describes spe- 

 cimens from Corea which differ in being smaller (length of forewing 18 mm) and less woolly; body slenderer, 

 abdomen blacker, with golden yellow anal tuft; wings above dark black-browTi with the exception of the 

 margin and a broad pointed stripe along the costal margin, which are golden yellow; at the costal margin 

 not far from the apex the black spot is very sharpl}^ indicated, on the underside of the forewing the whole 

 coreana. area is black. This form has been named coreana by Staudinger and is perhaps a different species from niphonis. 

 Larva until Jime on Ostrya. 



piperita. E. piperita Oberth. (21 e) resembles flava Brem.-. gi'ound-colour bright yellow, markings violet-brown, 



with black dots, forming a broad transverse median band extending distad, not quite reaching the costal 

 margin and usually united to a large basal spot, so that only a small triangular spot remains j^ellow bet- 

 ween the two at the inner margin. Behind the curve of the median band there are two small dark spots close 

 above one another, while there is a tliird before the apex and a fourth close to the inner margin. Underside 

 pale yellow, suffused M'ith blackish in the middle. Hindwing pale yellow above and below. S 26, ? 35 mm. 

 In true 'piperita the median band is said to be like the head of a dog (,,a la forme d'une tete de chien") 

 and the basal spots are not mentioned in the original description, however the description is very poor. If the 

 basal spot is really absent in true piperita, the form described above would have to be kept separate as a good 



snelleni. variety vuider the name of Snellen! Stgr. — Described from Amurland, is also said to occur in Japan, South and 

 West China. 



pulverea. E. pulverea Leech (21 f), from. Japan and Corea, is similar to piperita, but is smaller and has no 



dark markings apart from brown scales which are sparsely distributed from the base almost to the margin, 

 forming a kind of a mantle-shaped mark, whose outer margin bears a few silvery spots. Hindwing and under- 

 side of both wings leather-yellow without any markings. 



conspersa. E. conspersa Butl. (21 f), from Japan (Yokohama), has the forewing ochreous, the basal two-thirds 



being dusted with black scales, with the exception of a light angulate band close before the basal third; at 

 the distal edge of the black area there is also an indication of a lighter band; two black subapical spots. 

 Hindwing deeper ochreous than the forewing. Underside of forewing with white inner margin, the basal 

 three-quarters of the wing suffused with light brownish. 36 mm. According to Leech the ^ is sometimes deep 

 choka. chocolate-colour: ab. choka nom. nov. 



staudingcri. E. staudingeri Leech (21 f), from Japan, is deep leather-coloured or bright ochreous; forewing with a 



purple brown basal smear and an elbowed central band constricted in the middle and at the costal margin and 

 merging together with the basal smear at the hindmargin; diseocellular spot black, large and round. Hindwing 

 without spot. Head and thorax orange, abdomen velvet^' black, orange at both ends. Underside leather-yellow, 

 forewing darker in the centre.
