HYALOCOA: HYPERBOEEA; NYCTEMERA. By Dr. A. Seitz. 103 



short ciliae. The abdomen of the $ is stout, cyhudrical, that of the ^ slender and hairy. The larvae are 

 very brightly coloured, with sparse hair, and feed on Senecio; pupae very glossy, stumpy, immobile, on the 

 ground. The moths fly on stubble, pastures and alpine meadows. 



H. jacobaeae L. (= senecionis GW<.) (18 h). Forewing grey; inner margin, a stripe below the costal jacobaeae. 

 margin, two marginal spots and the hind wing purple-red. Europe and Western Asia to the Altai. In 

 ab. gilleti Andre (= confluens SclntUz) the red markings of the forewing are more or less confluent. In giUeti.

 black marked with yellow, and the hairs sparse and brownish; on Senecio vulgaris, S. paludosus, said to 

 feed also on Tussilago; full-grown in July and August. Pupa l)lack, glossy, in a cocoon on the ground: 

 the moth in May and June, on meadows, flying by day when flushed; settles on stalks of grass. Com- 

 mon everywhere. 



73. Genus: Hyalocoa Havips. 



This genus also contains only one species, which was formerly placed with Hipocrita. But the 

 areole is absent, and it is doubtful whether the genus ought to be placed here at all. Head small; eyes 

 very large; palpi small; tongue quite aborted; antennae simple, thorax and abdomen very slender in the^. 

 in the $ stouter, short and rather club-shaped; wings comparatively broad, very thinly scaled. Nothing is 

 known of the early stages; the only species inhabits East Asia. 



H. diaphana El-. (18h). Sooty grey-brown; head and thorax darker, collar bright reddish yellow, diaphana. 

 abdomen paler yellow, in the ? with dark doi-sal spots in the middle. Wings without markings, diaphanous 

 grey-brown. Seems rather rare, in Amurland and near Irkutsk, in May and June. 



74. Genus; Hyperborea (Jr.-Grsh. 



This genus contains one East-Asiatic species resembhng Parasemia in facies. Slender, with small 

 head, short palpi, simple antennae, large tegidae, slender abdomen, broad triangular forewing and large, 

 almost circular hindwing. 



H. czekanowskii Gr.-Grsh. (18 h). Forewing grey-brown, semitransparent ; a white costal stviTpe, czejxanows- 

 another above the inner margin and two crossed stripes in the outer area; tho veins are also white, narrow, 

 and sharply defined. On the hindwing the margin is irregular, grey-brown, and before it, on the semi- 

 diaphanous ground-colour, are two spots below the apex and above the anal angle. From the Tunguska 

 River. 



75. Genus; Xycteiiiera Hbn. 



Moderately large, slender moths, usually black and white in colour with simple markings. Head 

 rather large, on a long constricted neck; eyes prominent: ocelli present; palpi moderately long, porrect, 

 with thin end-segment. Tongue developed. Antenna of S pectinated. Thorax thin, tegulae spotted, 

 abdomen of (J slender, in the $ cjdindrical, usually with dorsal spots, very smoothly scaled. Wings 

 broad, usually white with dark edges, forewing with distinct areole. Larvae as far as known yellow or red 

 with dark rings, some with tufts of hair, many hving on Senecio. Pupa smooth, thin-skinned, in a loose 

 cocoon; before the moth emerges one can see the spots of the thorax and abdomen shining through. 

 The moths are on the wing in daytime, their fhght being restless; they seem to be protected; I saw a 

 dragon-fly which had caught a A', conica let it go again after a few seconds. Pagexstecher, who 

 monographed the genus, enumerates about 80 mostly Indo-Austiahan forms. Only two forms extend to 

 the Palearctic Region at its southern boundary. 



N. plagifera Walk. (18 h). White with blackish brown discal and marginal markings. Thorax and plagifcra. 

 abdomen spotted with black, tip of the latter and the head yellow. Common throughout India, north- 

 wards to Tibet, China and Formosa. In warm districts during the whole year, in the Palearctic Region 

 more in the autumn, flying together with Pieris canidia, from which it can scarcely be distinguished when 

 on the wing. 



N. lacticinia Cr. (18 h). Thorax anteriorly yellow spotted with black. Forewing black-brown vdth I act icini a 

 white obhque band before the apex rounded at both sides, and a white stripe basally at the inner margin. 

 Hindwing white, semivitreous, with broad, proximally irregular, marginal band. Throughout India, Southern 

 China ana Formosa. Lar^-a grey, dorsally red, this colour- being inteirupted by tufts of hair situated on 

 warts; at ths sides of the head two porrect tufts of hair; found on Cacaha conchifolia. Common.
