Hab, Sarepta, S.Ei Russia, Crimea, Askabad, 

 Syria. Lepsa, Central Asia, North Tianchan, 

 Byschtan and Tschaptschatschi on bhe Lower 

 Volga, the Ural River, Amasia. IV., V. 



Larva. Yellow, with a white lateral band and 

 Large black points arranged in threes on the sides 

 ui' each segment. On Sinwpis incana and other 

 Crucifers. 

 Pupa. Whitish, not boat-shaped. 

 a. ab. tschudloa II. S. II'.'. 150. Smaller than 

 type. Pure white above. U.S. h.w. w th large 

 white spits; orange apical patch very small. 

 Hab. Sarepta. 



h. var. menestJio Men. Cat. Rais. p. 245. A large 

 form of the species. The disc, spot f.w. is narrower 

 and often divided into two; the greenish-yellow 

 colouring of the u.s. is lighter and more extended. 

 HAB. Amasia. Syria. IV. 



c !var. meridionalis Led. Z. b. v. 1852, p. 30. 

 Lg. B. E. p. 44, pi. x. 3 (Z menestho). Larger than 

 Z. eupheme. F.w. with the dark shading at the 

 apex more strongly marked ; disc, spot large and 

 doubled, especially in $ , in which sex the orange 

 is almost absent from apex. U.s. h.w. deeper 

 yellow than in type. Hab. Spain — Leon, Anda- 

 lusia. Castile. Larva, according to R. H., greenish 

 yellow, sometimes entirely suffused with red, finely 

 pilose, with black lateral spots. On Sinapis, Ra- 

 phanus, and Urassica. If this form is co-specific 

 with Z. eitphcnw, and not distinct from it, it is 

 remarkable that it should present so striking a 

 solution of continuity in the distribution ; for 

 whilst Z. eupheme is confined to the extreme S. E. 

 of Europe and W. Asia, the form meridionalis is 

 found nowhere but in Spain, and no other European 

 country has a Zegris amongst its fauna. It is quite 

 possible that this is really a distinct species, though 

 in appearance it differs from Z. eupheme only by 

 slight characters. 



3. Z. fausti Christoph. Hor. Ent. Soc. Ross. xii. 

 pi. v., Lg. B. E. p. G9. 



35 — 37 mm. 



Wings pure white, $ f.w. with apices bright 

 orange, almost scarlet, and very slightly black at 



outer edge, but with a broader, blacker, and 

 straighter internal band than that seen in Z. 

 eupheme. Disc, spot larger and less crescentic. 

 U.s. h.w. green, with large silvery spots and no 

 yellow colouring. $? with apex f.w. less brightly 

 red and with more Mack. 



Hab. Turkestan (no! Amur). Krasnowod* k, 

 Kisil-arwat, Ferghana, Osch. IV,. V. 



This is a well-marked and beautiful species, 

 quite distinct fr anj of the forms of Z. evplieme. 



By an error on p. :;•';! this species i- stated to 

 occur in the Amur. It seems to lie confined to 

 Turkestan, in the neighbourhood of the Caspian, 

 and not to oeenr eastward of that region. 1 wa- 

 misled in 1884 when 1 gave Siberia ;i- ;i Locality 

 lor this species. 



Genus i:i. LEUCOPHASIA Steph. 



Head moderately large, eyes large and promi- 

 nent, palpi longer than the herd and covered with 

 strong hairs. Antennae of moderate length, fur- 

 nished with a flattened oval club. Abdomen very 

 slender, reaching beyond h.w. Wings white. 

 rounded, and elongated. Discoidal cells very small. 

 Subcostal nervure five-branched ; all the branches 

 are given off beyond the cell. Larvae pubescent, 

 tapering at the ends. Pupa angular, not boat- 

 shaped. 



1. L. sinapis L. Syst. Nat. x. 648. Lg. B. E. 



p. 45, pi. x. fig. 4. " Wood-white." 

 35 — 40 mm. 



Wings white, f.w. with a circular blackish blotch 

 at apex. U.S. f.w. faintly yellowish-grey along 

 costa and at apex. H.w. yellowish streaked with 

 grey. 



Hab. Europe (except the Polar portion). In 

 Britain chiefly in the south and west, but also in 

 the Lake District and other places. On the Con- 

 tinent it is common and widely distributed, in 

 England very local. It extends throughout West- 

 ern Asia, and occurs in the Amur. Corea, and 

 Japan. IV.. V.— VII.. VIII. 



Larva. Green with a darker dorsal stripe : be- 

 neath this is a _yellow stripe. On Vioia, Lulus. 

 Zathyrvs, and other Leguminosae. 



Pupa. Yellowish-green or grey rusty on the 

 sides and wing-cases VI. and IX. 



This species presents marked seasonal variation. 

 There seems to be some difference of opinion 

 respecting the nomenclature of the various forms. 

 I subjoin them as they are given by R. & 11. 



a. var. lathyri Hub. 797-8. Gen. I. The u.s. 

 h.w. shows a darker green colour. Flies with the 

 type in S.. Europe and Western Asia. IV., V. 



I>. ah. -,' erysimi. Bkh. i. 32. Wings entirely 

 white above. Hab. Occurs with type throughout 

 Europe. A dimorphic form of $ found with 1. 

 and 11. general ions. 



c. var. diniensis Bdv. g< n. ti. Apex of F.w. rather 

 less rounded than in type. Wings entirely white 

 beneath Apex of f.w. above varying in the in- 

 tensity of the black patch. Occurs as a variety- of 

 the second generation. Hab, Principally in S. 

 Europe.
