82 European Butterflies and Moths. 



23. 5". Stclidiformis (Freyer). — Blackish-brown ; thorax with three longitudinal yellowish 

 stripes ; hind margin of the fore-wings streaked with yellowish ; the 4th segment of the abdomen 

 bordered behind with a white belt, which covers the segment almost completely in the middle 

 and at the sides. It varies considerably in colour, as well as in size, expanding from three-quarters 

 to one and a quarter inches. Common in Southern and Eastern Europe. 



24. 6'. Rambtcrii (Staud.). — Brownish-black ; the outside of the antennae scaled with ochre- 

 yellow, hind margins of the fore-wings with obscure yellowish stripes ; abdomen, with segments 

 2, 4, and 6 in the female (as well as 4 in the male), belted with white. It is nearly allied to 

 6". Doleriforinis, but is more slender, and the forehead, coxe, and abdomen are darker, although 

 the general colouring of this species is whiter. Expands about i inch. It is found in Andalusia 

 in June. 



25. S. Laiiipes (Led.). — Allied to Doleriforinis, but whiter, and with the tibije still more 

 densely tufted. The body and fore-wings are dull blackish-brown, and appear to be covered with 

 fine whitish atoms. Segments 2, 4, and 6 of the abdomen are bordered with white behind, and 

 the remaining segments have only obscure narrow yellowish-brown hind borders. The anal 

 tuft is blackish-brown above, and white below and at the sides. Expands nearly i inch. It 

 inhabits the mountains of Bulgaria. 



26. S. Agdistiforniis (Staud.). — Brownish-grey ; the wings not hyaline ; fore-wings with 

 whitish stripes towards the tip, and whitish spots in the middle ; hind-wings whitish, with the 

 broad hind margins and the nervures smoky ; abdomen unicolorous and very slender ; anal tuft 

 whitish beneath and at the sides. Expands i inch. It is found at Sarepta. 



27. 5". Bibioniformis (Esp.). — Much resembles the following species, but the antennae are 

 suffused with yellowish on the outside, and the disco-cellular nervule of the hind-wings is 

 uniformly thick, and almost equally broadly scaled. The palpi and front co.x^e are pure white, 

 and the abdomen has generally a series of small whitish spots in addition to the yellow scaling. 

 The anal tuft is mixed with white, and the three longitudinal stripes of the thorax are yellowish- 

 white. On the under side the white coloration is predominant. Expands three-quarters of an 

 inch. It inhabits South-Eastern Europe and Western Asia. 



28. * .S". Muscaforniis (View.), P/ii/aiit/iiforiiiis (Lasp.). — Brownish- black ; the thorax with 

 three yellow longitudinal stripes, the front of the eye-caps and segments 2, 4, and 6 of the 

 abdomen white, the palpi and coxae white or yellowish, and the abdomen above dusted with 

 yellow, often so as to form a series of small spots ; anal tuft mixed with yellow. The band 

 and margins of the fore-wings are dark brown, the latter dusted with yellow ; the disco-cellular 

 nervule of the hind-wings is broadly scaled with blackish above, and is narrow behind. The 

 antennae are not suffused with yellowish, but are whitish before the tips in the female. Expands 

 three-quarters of an inch. Appears to be widely distributed in Central Europe in June and July. 

 It is a very local insect oh the coast of England, where the larva lives for one season in the upper 

 part of the roots of the sea-thrift. It has been found at Torquay and in the Isle of Man. 

 {S. Leiicome/cEiia, Zell., is of a smaller average size, and has the palpi and front coxae beneath, 

 and only segments 4 and 6 of the abdomen, bordered behind with snow-white ; the transparent 

 space at the tip of the fore-wings is nearly always composed of five cells. It occurs in Turkey. 

 .S. Corsica, Staud., is another form closely allied to this, which is distinguished by the very small 

 transparent spaces of the fore-wings, the outermost composed of three cells only. It is found 

 in Corsica, and is of the size of Latcoineltzna. Both these forms are perhaps only southern 

 varieties of Muscafonnis!) 



29. 5". Affinis (Staud.). — Very like Muscceformis, but the middle yellow line on the thorax is
