U.S. f.w. with a yellowish-green apical patch square 

 in outline. H.w. entirely yellow-ereen with dusky 

 suffusion. Hab. S. Europe, Asia Miuor.

45 — 50 mm. 



A much larger species than L. sinapis, from which 

 it is quite distinct. Wings pure white. F.w. 

 slightly angulated at apex and having an apical 

 circular patch of deep black in S , lighter in o ,

sometimes in that sex almost absent. U.s. f.w. 

 very faintly yellowish at apex and along costa. 

 H.w. white, with a very indistinct trace of a dusky 

 transverse band. 



Hab. Ask., Chab., Vladimar Bay, and other 

 places in the Amur, also Japan. V. and VIII. 



a. var. vernalis Graeser. K. H. p. 143. 35 — 40 

 mm. Smaller than type ; ground-colour yellowish- 

 white, with the black apical spot less marked and 

 less denned in outline. Amur. V. 



3. L. duponeheli Stgr. Cat. 1871, p. 5. Lg. 

 B. E. p. 46, pi. x. fig. 5. 



36 — 38 mm. 



Differs from L. sinapis as follows : Apex f.w. less 

 rounded ; apical spot less defined at inner edge, 

 extending much further in a downward direction. 

 H.w. greenish-grey, with two white blotches ; bases 

 decidedly tinged with yellow. U.s. h.w. quite 

 different from those of L. tinapis, uniform greenish- 

 grey, with two white blotches, one central, the 

 other marginal ; both triangular in shape. Clubs 

 of antennae blacker than in L. sinapis.

a. var. aestiva R. H. p. 143. The summer genera- 

 tion. Apical blotch, f.w. paler in colour and less 

 extensive, shaped more like that in L. sinapis. 

 Hab. as type. VII. 



I have taken both Leueapliasia dvponcheli and 

 var. aestiva at Digne, where the species is common. 

 The difference between them appears to be marked 

 and constant. This species is very distinct from 

 L. sinapis, but is very local and of limited dis- 

 tribution. The two species, L. sinapis and L. 

 duponeheli, fly together at Digne ; but the flight 

 of the latter is stronger and more sustained. By 

 this character they may be distinguished when on 

 the wing with some amount of certainty. 



Genus 14. TERRACOLUS Swainson. 



Antennae rather short and thick, with a broad 

 blunt club. First and subcostal nervules of f.w. 

 close together. Colour of wings white, orange, or 

 yellow. This genus contains a number of species 

 of widely differing appearance, some of them 

 having the aspect of Anthocharis, and others that 

 of Colias. They are mostly African or South- 

 western Asiatic. These species, however, extend 

 into the Palaearctic region. 



1. T. fausta Olivier, Voyage en Syrie, pi. 33. 4. 

 Idniais fausta Stgr. Cat., et al. auct. 



35 — 40 mm. 



Ground-colour of wings a peculiar light reddish- 

 yellow, very difficult to describe. Shape of wings 

 resembling that of Colias hyale. F.w. with a 

 double row of narrow black marginal spots ex- 

 tending from the costa nearly to the an. anp. 

 There is a small and indistinct black discoidal spot. 

 A black wavy band begins at the outer third of 

 costa and reaches to the first median nervulo. 

 Immediately about the submedian nervure in the 

 $ is a small patch of thickened scales. H.w. 

 without markings, excepting a row of five very 

 small marginal black spots. $ less brilliant in

colour than S , but with all the black markings 

 stronger and much more pronounced. U.s. very 

 light yellowish-orange, especially the h.w., which 

 are neai-ly white in J • There are no proper mark- 

 ings except a very faint trace of a narrow central 

 band of yellow on the h.w. The dark markings of 

 the upper surface show through more or less.

F.w. salmon-colour, black at base and along 

 costa, with a broad black marginal band containing 

 three spots of the ground-colour, two near the apex 

 and one in the centre ; discoidal spot black and 

 distinct, but touching the black costal shading. 

 H.w. white with a broad black unspotted marginal 

 band. U.s. light yellow dusted with grey. No 

 marking except on f.w. Disc, spot and three
