NEW LEPIDOPTERA. 



By THE HON. WALTER ROTHSCHILD. 



1. Papilio aristolochiae lombockensis suhsp. nov. 



(??. U\ie P. aristolochiae anliplnis. hut differs as follows: the white streak? 

 on the underside of the forewing are much shorter and narrower, the black border 

 of the wing being almost twice as broad as in antiphus from Sumatra ; the red sub- 

 marginal spots on the hindwing below are mostly larger and less linear, the middle 

 ones often overpowdered with black scales ; the tail is broader at the base and at 

 the apex, being sometimes as broad as in aristolochiae kotzebueus. 



Hah. Sawela, Lombock Island, 1000—2000 feet, June 1896 (W. Doherty). 



2. Papilio memnon clathratus subsp. nov. 



Papilio memnon merupii, Nnv. Zocil. 18'Ji. p. 315 (t) {rx p.). 



I am now in possession of a Sumba specimen of merapu, and find that W. Doherty 

 was right when he told me during his last visit here that the Sanibawa and Sumba 

 memnon are not identical, but belong to two subspecies. Therefore I ha\e to give 

 a name to the Sambawa form. Besides the inferior size, clathratus is distinguished 

 from merapu by the marginal area of the underside of the hindwing being less 

 ochreous, mostly grey, and more extended on the disc, and by the grey rays of the 

 upperside of the hindwing being, near the margin of the wing, broader. Tlie female 

 of TTverapu is unknown ; that of clathratus I have described in Nov. ZooL. 1895. p. 316. 



Hah. Sambawa (\V. Doherty, September 1891). 



3. Papilio albinus thomsoui ah. mordiugtoni ab. nov. 



This most singidar specimen reminds one strongly in its style of aberration 

 of Papilio nubilus Stand, and P. walkeri .Tans., and I should have gladly given 

 it equal specific rank with these two forms, but it was sent together with a great 

 number of P. albinus thomsoni which show so much variation that I can clearly see 

 that this specimen can be made out as an extreme sport. 



Forewim/: black-brown, with a few white scales between cell and apex. 



Hindwinij: black-brown; four wiiite patches on disc, one in apex of cell 

 extending half-way to base and rather ill-defined, the second between veins 6 and 7, 

 the third almost obliterated between 2 and 3, and the fourth triangular before vein T. 

 One oblong red jiatch between abdominal margin and vein 2 near anal angle; another 

 more indistinct, 11 mm. long, between veins 2 and 3. 



Underside as above, but hindwing without white patches ; the two red patches 

 near anal angle larger and much more distinct. Both above and below these two 

 spots are dusted with blue .scales. 



The two first of the series of red sulmiarginal spots of albinus are present, 

 although altered in shape. 



Hab. Little Kci Island, one ? (('apt. II. Cayley Webster). 



Although as a rule I do not give a per.sonal name to an aberration, I do so in 

 this case at tlie request of the collector.
