Moerua is confined to places of fairly light rainfall, where the veget- 

 ation is comparatively" scant and more or less desert localities. 

 Heia,ce the butterfly is also confined to snch places ; so that Colotis 

 fansta and its form tripuncta are found in Baluchistan ; Sind ; the 

 Panjab ; Rajputana, extending westward to Afghanistan, Persia, 

 Arabia, Asia Minor and European Turkey ; Western and Southern 

 India; the Nilgiris up to 6,000 feet, the Anamalai Hills; Eastern 

 India ; Orissa in Bengal, Ganjam ; Ceylon. Fausta is supposed not 

 to extend south of Bombay ; triinmcta is supposed not to exist in 

 Sind. This latter however does occur in Sind round Karachi and the 

 probabilities are that the two are really one species, notwithstanding 

 that only tripuncta has seemingly, always, the white form of the 

 female. 



121. Colotis eucharis — M.&\6, upper side: pure white. Forewing : base and 

 costa for a short distance generally sparsely irrorated with black scales ; 

 a broad, apical, orange-yellow patch with its inner edge straight and 

 margined with gamboge-yellow ; this spot is sometimes immaculate but 

 generally bears a black, diffuse spot on its lower, inner edge which may or 

 may not extend to the termen below the orange ; costa, apex and termen, 

 the latter nearly up to the tornus, edged and festooned beyond the orange area 

 with black. Hindwing : with black spots at the apices of the veins that 

 vary in size and end on the termen, also a diffuse, preapical, black spot 

 on the costa. Underside : pure white in most specimens, suffused, except on 

 the disc of the forewing, with pinkish-yellow and, at base of the same wing, 

 with pure sulphur-yellow ; apical, orange patch and terminal, black mark- 

 ings on the upperside of the forewing show through by transparency, the 

 former crossed by a sinuous, fuscous fascia that ends in a diffuse, black spot. 

 Hindwing : shaded with ochraceous at base with a fuscous, preapical spot 

 on costa ; also a few scattered, transverse, fuscous stride and small spots. 

 Many specimens have the preapical, fuscous spot continued as an obscure, 

 fuscous fascia across the wing and bear a series of large, terminal, fuscotis 

 spots that correspond to the black spots on the upperside. Both wings with 

 black, discocellular dots. Antennse, head thorax and abdomen black ; 

 antennae speckled with white on the sides ; head and thorax clothed with 

 short, greyish-brown hairs ; beneath : palpi, thorax and abdomen white. 

 Female : ground-colour similar, the markings differing from those of the 

 male as follows: — Upperside, forewing: base and costa more heavily irrorat- 

 ed with greyish black scales ; discocellular spot larger ; apical area black, 

 with three enclosed, elongate, orange spots ; inner margin of black area 

 irregularly sinuate and diffuse, extended shortly inwards in interspace 3 ; a 

 transverse, black spot across middle of interspace 1. Hindwing: base 

 irrorated more sparsely than the forewing with greyish-black scales ; 

 preapical-costal and terminal spots much larger ; in a few specimens there is 

 an obscure, transverse, posterior, discal fascia. Underside : markings similar 

 to, but very much broader and more heavily marked and more prominent 

 than, those in the male ; the transverse, fuscous strife and dots more numer- 

 ous. Antennte, head, thorax and abdomen as in the male. Expanse 

 36-50mm. 



JEffff. — The egg is shaped as in the marginal figure which is magnified 

 thirty times. It has 17 longitudinal ribs, some of which coalesce before 

 reaching the top ; reaching the top, after coalescing, in a single point or 

 tooth for each ridge thus formed, each composite ridge no broader than 

 either of the original two (or three) ; the teeth form a tiny crown around
