EUPITHECIA. ByL. B. Prout. 



gratiosata. E. gratiosafa H.-Sch. (^ subseparata Chr.) (12 d). Median band similarly formed to that of c/iieneata 



but more traversed by white lines; ground-colour always glossy white. Very variable; in the typical form 



lavata. well marked. — lavata Fuchs from Sicily is somewhat larger and less sharply marked, but the differences do 



pallida, not seem important. — pallida Dietze, from Orenburg, perhaps only an individual aberration, is much lighter 



still, with the abdomen entirely white. — Larva on the seed-umbels of Ferulago galbanifera. Distributed on 



the Mediterranean littoral, and from the Balkan through Asia Minor to Central Asia. May — June. 



bveviculata. E. bfcviculata Donz. (13 g). Easily known by the pure white ground-colour, brown basal patch reaching 



nearly to the black discal dot and brown apical half of the distal area of the forewing. Larva on flowers and 

 seeds of Ptychotis heterophilla, an Umbellifer. The pupa hibernates, sometimes twice. S. Europe, France, 

 N. Africa, Syria, Asia Minor and Transcaucasia. 



extremata. E. extremata i^^. (= glaucomictata ilfaww) (13g) vesembXes hreviculata but is somewhat narrower-winged, 



less pure-white, the markings less bright brown, the basal area more variegated, sharply dark-edged distally, 

 the postmedian line represented by dark vein-dots (dashes), without the grey double line or band of breviculata, 

 the distal patch on costal margin more restricted, not reaching the distal margin, more blue-grey than brown. 

 Hindwing more strongly marked. Larva unknown; said to live on Clematis (Mabille). Local in Central and 

 South Europe, Asia Minor, Syria and Transcaucasia. 



stertzi. E. stertzi Rbl. Affinities uncertain; recalls Gymnoscelis, but hindtibia 4-spurred. Wings rather elongate, 



whitish with a tinge of ochreous; forewing slightly more reddish costally and distally, basal patch dark fuscous, 

 small, but almost united by dark shading with a narrow fuscous band, which arises before middle of costal 

 margin and forms a strong curve or angle distally at the submedian fold; some blotches in the distal half of 

 the wing, but leaving a clear area between the 3'''* radial and 2"'' median; fringe strongly spotted. Hindwing 

 with curved transverse lines, strongest on veins and inner margin, a small dark inner-marginal patch close to 

 base. Antenna in cf with slender fascicles of long cilia. Teneriffe: Orutava and Guimar in March. 



f.halictrafa. E. ttialictrata Pilng. (13 g). Dark grey-brown, the forewing with indistinct pale markings somewhat 



recalling those oi pumheolata ov valerianata ; from the costal margin to the subcostal and more or less on the 

 veins these pale lines are generally rather more distinct, in particular the double line distally to the median 

 area; subterminal line obsolete. Larva on the flowers and fruit of Thalictrum foetidum. The pupa hibernates, 

 the moth emerging in May and June. Only known from Valais. 



actaeata. E. actaeata Walderdorff (12 i). A rather large, rather broad-winged species. The large discal mark and 



dark costal spots remind of trisignaria, but the postmedian is placed nearer to the cell-spot; a conspicuous 

 bergunemis. whitish spot near the hinder angle of the forewing. — bergunensis Dietze is an essentially larger, more distinctly 

 marked form from the Alps and the far north. — Larva on Actaea spicata, also, in the Alps, on Thalictrum 

 aquilegifolium. The pupa usually hibernates, but sometimes produces a partial 2""^ brood in September. The 

 principal emergence is in July. Switzerland to East Prussia, also in Finland and again in Transbaikal, Amur- 

 land and the Ussuri district. Probably also in Japan (Dietze). 



selinata. E. selinata H.-Sch. (13g) is near trisignaria but may be distinguished by its broader median area, 



generally less thickened costal spots, weaker subterminal line, obsolete discal dot on the hindwing and according 

 to Dietze longer ciliation on the basal part of the cT antenna. Larva on the flowers and seeds of Umbelliferae, 

 especially Angelica, Peucedanum and Heracleum. Moth in May, with a partial 2"'' brood in July, distributed 



addictaria. in Central Europe from the Pyrenees to the Ural. — addictaria Dietze, perhaps a separate species, is smaller, 

 more ash-grey, less greasy-looking, discal spot of forewing smaller aud rounder, the costal darkening of the 

 lines slighter; forewing traversed, at uneven distances, by slender darker lines, of which about 12 can be 

 counted on the costa; between them there are some scattered withish-grey scales, especially distally to the 



tenebricosa. median area, where they tend to form a double line. Hindwing almost unicolorous. Ussuri. — tenebricosa 

 Dietze is an aberration (?) with a dark sinuous (S-shaped) band on the middle of the hindwing. Radde, 

 Amur (1); Ural (1). 



trisignaria. E. trisignaria H.-Sch. (12g). Moderately variable, though always obscurely marked. On the differentiation 



from actaeata and selinata I have already spoken above ; the palpus is somewhat shorter than that of selinata. 

 Sometimes the only distinct markings are the three dark spots (2 costal and the cell-spot) from which the 

 species receives its name. Larva on various Umbelliferae, especially Heracleum, Pastinaca and Angelica. Moth 

 May— July, distributed in Central Europe. 



Jatipennata. E. latipennata noni. nov. (= latipennis Warr. nee Hulsi) is a rather large species, characterized by its 



rounded costa, pointed apex and strongly oblique distal margin. Palpus long. Forewing fuscous, somewhat
