S6 SPILAECTIA. By Dr. A. Skitz. 



different from that insrct. The lihick liasc (if the costa is very distiuct in tlic j ami tin- olihtjm^ row 

 of dots on the forewing varies strongly in development. Hindwinj^ above and below often stronglj' suf- 

 fused with rose-red. This ri'ddish hue may also be continued on the forewing, this being tiie case in 



bu-ilimbala ''''• fOSacea £»//. In ab. basilimbata Vii///. there are dark shadows in the internervular spaces of the fore- 

 wing. The larva, according to tfT.\UDiN«ER, very like that of Spilos. menthasiri, somewhat darker 

 and especially distinguished from it by the hairs of the sejiarate tufts being denser. East Siberia, North 

 China, Corea and Japan, locally very common. 

 inacqiudis. S. inaequalis Bull. (15 c).- Very like the two preceding, smaller, the obhque row of dots of the 



birewing always complete, as in caHUjnctd; distinguished from this form by the palpi being carmine below, 

 instead of lieing black as in casigmiii. The groun(l-c<»lour \ai'ies from orange-3'ellow to creamy-white. 

 In .rajian. not lare. 



coslhnacula. S. costimacula LeccJi (1-) c). I'mewing creamy-white, hindwing usually snow-white, thorax white 



with yellow markings; abdomen rose-red. Forewing with brownish spots at and below the costa, and with 

 a very regular, somewhat curved, oblique row of brownish dots. In West China, Washan and Mnpin. 



rhodophila. S. rhodophila Walk. (= rubridorsa Moore) (15 c). ^lill;y white, head yellowish, abdomen rose-red, 



with dots which are very faint in the $ and almost indistinguishable in the J. Lateralh' on the neck 

 distinct small rose-red spots. From Kashmir to Western China; also in the Indian Himalayas, not being 

 rare in Sikkim. Often only a discal dot and the oblique row of dots remain of the black markings; of 

 the forewing. The species varies greatly as regards the size and intensity of these markings, a more 

 weakly marked form (dorsata) has been separated from the form with stronger markings [rhodophila). — 

 Larva dark brown, light brown laterally, wuth a reddish brown head. White streaks dorsally and rows 

 of pale ones laterally, hairs long, on yellowish M'arts. On low-growing plants. 



iankowskii. S. jankowskii Oi)cr//(. (15 c). Forewing and thorax ivory yellow', hindwing pure white, abdomen red, 



base of abdomen with white hairs. Very fine black spots at the apex of the cell of the forewing, travers- 

 ing the latter in an oblique and sometimes interrupted row, which does not often extend beyond the 

 submedian vein. In the $ usually only that part of this oblique row beyond the apex of the cell is 

 soror. distinct, the lower part Ijeing only slightly indicated. From Amurland. — The form soror Leech, from West 

 (Tiina, has no discocellular spot on the forewing, the oblique band of spots curves towards the costa, 

 and there is a further sjjot at the inner margin. — Larva (last but one stage) black, the hair appearing 

 grey because consisting of a mixture of black and wliite hairs; laterally on each segment three brown 

 streaks, one abo\-e the other: head lirown; venter with brown sjjots. Moth in August. 

 sHbccirn(M. S. subcarnea Walk. (= bifrons Walk., leucothorax Fldr., erubescens Moore, trybakowi Alph., ober- 



thueri Semp.) (15 d). Thorax and forewing ivory yellow, the latter usually finely spotted with black. 

 Hindwing purple-red or white, slightly suffused with rosy-red, seldom without a red tinge. Abdomen 

 bright blood-red, white at base and apex, with black dots dorsally. Throughout Japan, Corea and China; 

 eastward to the Philippines and southward to the Malay Archipelago. 

 robusta. S. robusta Leech (15 c) is probably only a more robust form of the preceding, the (^ having black 



dots on the tegidae, wdiile the spots on its wings are on the contrary somewhat reduced. Underside, as 

 in suhcarnea, often suffused with rosy-red. West China. Perhaps a seasonal form. 

 sligmaia. S. stigmata 3/oore (= lacteata B«<L) (15 d). Light ivory yellow', hindwing creamy white; abdomen 



carmine. On the forewing, beginning at the apex, there is an abbreviated row of fine short black comma- 

 shaped dashes, and a dark row' of dots interrupted at the apex of the cell. The hindwing has a small 

 black spot before the apex and two to four similar spots above the anal angle. In the $ the black 

 markings are less distinct. Distributed from Kashmir over Tibet (Yatung) to West China. Pupa black 

 with tufts of dirty white and black hairs; the hairs on the last segment reddish yellow. 

 comma. S. comma Walk. (= abdominalis Moore) (15 d). Thorax and wings pale orange-yellow, forewing 



with one or two costal spots aiad an abbreviated inner-marginal stripe, above the base and apex 

 of which there are small black spots, which may be connected with the costa by rows of dark shadowy 

 spots. Hindwing with dark discal dot, the basal portion often tinged with rosy red. Kashmir, appears 

 to be rare. 

 bifasciata. S. bUasciata Buil. (15 e). The largest Spilarctia; ? sometimes as large as Arctia caja. Thorax and 



w'ings orange-yellow; U\o wide black strijies, merging together at the inner margin, traverse the forewing, 

 the inner one of which is often interrupted, and the outer one sometimes also. Hindwing without spots, 

 or sometimes in the $ with one to three black discal spots. Abdomen orange-yellow; dorsally a row 

 of dots (rj) or transverse spots ($). Ho far only known from the Main Island of Japan, where it was 

 found at Tokio and Nikko. I caught two specimens near Yokohama. 

 flaveula. S. flaveola Leech (15 d). A small form, orange, suffused with red-lead colour, legs striped with 



black, abdomen pale red dotted with black above. Fore- and hindwing with a dark spot before the 

 apex of the cell, the former with and oblique row of spots. West China. 



jlammeola. S. flammeola ^1/oore (15 e). Likewise a small form; reddish orange; head light yellow, abdomen 



with fine dots, forcAving with two parallel rows of dots, ajid also like the hindwing with a dark discal
