and narrow. Southern France to Central .Spain, Nortliern Italy and the S(juthern Tyrol, ii\ hot summers also 



iemtata. in South- West Germany. The larva does not differ from that of true querciis. — tenuata Fuchs comes very 

 close to spartii; it occurs from Central Germany southw-ard and both sexes are dark-coloured and bear a nar- 

 ildhiiiitina. row band, which is very prominent on the dark ground. — ab. dalmatina Gerh., from Dalmatia, is hardly se- 

 parable from /e^mate and sjmrtii; the band of the forewing is narrow and that of the hindwing still narrower, 



viburni. and the fringes of the hindwing are dark, having only a thin light edge. — viburni G-'i<e«., which inhabits Southern 

 France, the Pjrenees, Italy and Sicily, is scarcely distinguishable in the imago from spartii and tenuata, but the 

 larva is well characterised, its ground-colour being darker, the deUcate long hair predominantly white, the 

 short felty hair of the dorsum bright reddish brown, the intersegmental bands narrower. The larva feeds on 

 various shrubs, such as Vibiirnum, Rubus, ffytisus, Erica arborea, Scoparium, etc., is full-grown early in January

aatalau- up into a ring when disturbed. — The extreme form of this series is catalaunica Stgr., from Catalonia and Central 

 Italy, in wliich tlie band is very narrow, being a mere line, (^ very dark brown, $ reddish brown. 



b. trifolii-group. 



L. trifolii E.sp. The numerous forms vary from deep reddish brown to pale yellowish grey, the body 

 being of the same colour as the wings. Forewing witli prominent, black-edged, white discal spot, both wings 

 bearing a narrow or more broad, sharply marked or sometimes quite obsolete, whitish transverse band, which 

 is often proximally bounded by a dark shadow on the forewing ; some forms have between the cUscal spot of forewing 

 and the base a dark dentate band, which sometimes bounds a paler basal patch. — Egg oval, flattened, with central 

 depression, lighter or darker yellowish grey shaded with brown or minutely dotted with black, deposited singly. 

 Larva black, hair greyish yellow to yellowish brown, rather short, dense and matted, intermingled with some 

 long tliin hairs, and sometimes foxy red on the dorsum. Incisions blackish blue or black, these bands rather 

 narrow, interrupted by tlu-ee white dorsal longitudinal lines, of which the median one is the most distinct. Head 

 reddish brown, witli black dots, frons yellow with black markings, pronotum and anal tergite reddish yellow 

 spotted with black. Segments 2 and 3 each with a red dorso-lateral spot, 4 — 10 with oblique whitish side-stripes. 

 Underside yellowish red, more or less extended black-spotted. Stigmata white. The larvae emerge late in August 

 and in Sej)tember, hibernate young and feed up from May or June on various Papihonaceous plants, preferably 

 species of clover, but also on Medicago, Genista, Ononis. The larva of the name-typical form usually in localities 

 with sparse vegetation, while tho.se of ab. medica.rjini.s prefer luxinious meadows. Pupa greyish green, in a regular, 



Irijidil. oval, hard, clayish cocoon. Moths from June until September. — True trifolii Esp. (25 c, d) is unicolorously 

 deep red-brown, with sharply marked discal spot, the band of the forewing being prominent in the ^, diffuse 

 in the $. The band of the hindwing is either absent or only vestigial. Distributed from Southern Sweden, 

 the Baltic provinces and England throughout Central and South Eurojie to Asia Minor, Armenia and Turan. 

 mcdicagi- With the name-tjrpical trifolii, and in some places even more commonly than this, occurs medicaginis Borkh. ( = tri- 

 '"*'• folii Panz.) (25 d), which is more greyish brown, the forewing and thorax being densely shaded with grey scales 

 and hairs and the dark shadow at tlie proximal side of the band of the forewing more prominent in consequence 

 of the paler tone of the ground; the fringes of the forewing dark reddish brown. In Asia Minor this form entirely 

 replaces true trifolii. — Also in this species Tutt has given names to the various gradation in colour and mark- 

 jUtva. ings: he distinguishes as ab. flava a pale yellow form with distinct dark, transverse, pale-edged band, several 

 modifications of this form being known, one without any markings (ab. obsoleta- flava), another with an in- 

 distinct pale median band between the lines (ab. pallida' flava), which band may be constricted or interrupted 

 (ab. contr acta- flava). The pale greyish brown forms comprise medicaginis Borkh., specimens of which without 

 markings being ohsoleta- medicaginis Tutt, while examples with a more or less distinct median band are separated 

 as virgata-medicaginis Tutt; here belong also ratamae H.-Schdff. and codes Hbn. (see below). The fawn-coloured 



ceivina. or reddish grey form with normal markings and distinct median band is ab. cervina Tutt (without markings 

 = ab. obsoleta-cervina Tutt, with constricted median band = ab. contracta-cervina Tutt). To the group with 

 red-brown ground-colour belong true trifolii and iberica G-iien. (cf. below); besides these Tutt calls specimens 

 with the basal band of the forewing obsolete in c? and $ ab. unilinea-typica, and a form with obsolescent trans- 

 verse bands and distinctly pale veins ab. suffnsa-ti/pica. Lastly, the examples with the very dark red-brown 

 rufa. ground shaded with deep red are ab. rufa Tutt, specimens without markings (= ab. obsoleta-rufa Tutt) or with 

 the median band constricted (= ab. contracta-rufa Tutt) also occurring. — Besides the Central European forms 



ibcrica. several well-characterized Mediterranean varieties are known, iberica G-uen. (= trifolii Dup.), from Spain, is 

 uniformly red-brown, having no markings apart from the almost black discal .spot of the forewing. It occurs 

 singly also in France, Switzerland and Southern Germany. — A form likewise inhabiting Southern Spain is
