58 Mr. A. G-. Butler on Delias belladonna. 



white; the yellow spot at anal angle is also perfectly separate 

 from the yellow commencement of the discal macular band, as 

 in the figure by Donovan ; the shape and markings of the pri- 

 maries are quite as in that figure, and therefore quite dissimilar 

 from D. Horsfieldii $ . 



I think therefore that we may conclude that Delias bella- 

 donna is a species confined to the North-west Provinces, that 

 D. Horsfieldii is confined to Nepal, and that other forms 

 allied to these may yet be expected to turn up. The two 

 following have been confounded with D. Horsfieldii : — 



Delias Hearseyi, sp. n. 



^ . Nearly allied to the Nepalese D. Horsfieldii, slightly 

 smaller ; the yellow patch at base of secondaries duller and of 

 a more orange colour ; the yellow patch on abdominal area 

 only represented by a dull yellowish nebula at the extremity 

 of the white area, which is restricted owing to the anal angle 

 being broadly black-bordered ; the yellow spot near anal 

 angle represented by a few white scales, whereas in D. Hors- 

 fieldii it is always present as a squamose yellow spot sub- 

 confluent with the abdominal patcli : on the underside all the 

 yellow spots are of a dull chrome-yellow, not bright gamboge, 

 as in D. Horsfieldii) they are also rounded and narrower than 

 in that species, so that they are in consequence smaller and 

 further apart. Expanse of wings 79 millim. 



Barrackpore (Sir John Hearsey). B.M. 



Delias Boylece, sp. n. 



J . Form and size of D. Horsfieldii, but in the coloration 

 of the wings much nearer to D. ithiela, the ordinary markings 

 being represented by internervular grey streaks, upon which 

 the submarginal spots of the primaries and three or four small 

 spots on the disk of all the wings alone show white ; base of 

 secondaries almost brick-red (or dull orange) ; basal half of 

 abdominal area grey, anal half bright chrome-yellow : below 

 all the spots smaller and much more restricted than in D. 

 Horsfieldii ', all the yellow spots duller, chrome-yellow. Ex- 

 panse of wings 84 millim.

Females in this group seem to be very rare ; of the four 

 species here mentioned we only have male examples in the 

 British-Museum series.
