1883.] MR. A. G. BUTLER ON INDIA.V LEPIDOPTERA. 153 



The females of this species are yellow below, as iu the males ; 

 sometimes with a row of browa spots on the secondaries. 



29. IXIAS KAUSALA. 



Ixias kausala, Moore, Ann. & Mag. Nat. Hist. ser. 4, vol. xx. 

 p. 49 (1S77). 



S ?. Depalpore, December 1881, January 1882. 



" Very common on the banks of the Depalpore lake iu November, 

 December, and January ; not observed anywhere else in this dis- 

 trict." -C. S. 



Chiefly differs from what I believe to be the 1. pyrene of Linnaeus 

 in the decidedly narrower black inner border to the apical patch 

 on primaries. 



SO. Ixias depalpura sp. n. (Plate XXIV. figs. 6, 7.) 



Allied to /. agnivena of Moore, but differing in the broader and 

 brighter orange patch on primaries and the narrower macular border 

 of secondaries. Wings above white ; primaries with the basi-internal 

 area almost to the middle of the wing white, tinted at base and 

 towards the costa with bluish grey ; a broad oblique black patch 

 across the end of the cell, continued in the male as a narrow 

 oblique black band to the external angle, so as to separate the basi- 

 internal and apical areas ; the latter area bright orange ; the costal 

 margin, apex, and external border black- brown, somewhat as in 

 /. mm-ianncB; the disk in the female marked with four small black 

 dots parallel to outer margin : secondaries white, with a marginal 

 series of subconfluent squamose brown spots somewhat as iu the 

 female of /. dharmsulee ; base greyish. Under surface similar to that 

 of/, agnivena and some examples of I. marianncB, but with only 

 four ocelloid spots towards apex upon the disk of primaries and with 

 no large brown patch at external angle ; the ocelloid spots on the 

 secondaries are large and white with pale cotfee-brovvn borders. 

 Expanse of wings 48-51 mm. 



Five examples. Depalpore, January 18S2. 



" This Ixias is also very plentiful at the same place in company 

 with /. kausala in the same months, and has not been observed any- 

 where else iu these parts." — C. S. 



31. PaPILIO DIPHILUS. 



Papilio diphilus, Esper, Ausl. Schmett. ph40 B. fig. 1 (1 785-1 798). 



Dudhi and Shahgunge in the Mirzapore distinct, N.W. Provinces, 

 in February 1882. 



The example from Dudhi is smaller than the other; and Colonel 

 Swinhoe regards the two as distinct local forms. This may be so ; 

 but hitherto I believe all have been regarded as varieties of P. diphilus; 

 and I should be sorry, with single specimens before me, to question 

 the correctness of this view.
