the beetles the Elateridce were dominant, and the Phytophaga 

 very rare. No species of Cassida was taken at all ; frogs, 

 toads, snakes, and lizards abound ; but he says nothing 

 about the birds, or the higher vertebrata. He collected 50 

 species of butterflies, and saw two or three more. Of 

 these he felt justified in considering 13 to be new, in- 

 cluding nearly all the Danaidce, and three species of 

 PapilionidcB, reckoning the Ornithoptera as one. The 

 following are Mr. Doherty's descriptions of P. Nerds, to 

 whch are added my own additional observations on his 

 types and co-types, from which the figures in the plate 

 are drawn : — 



" $ . Above black, the cell immaculate, the veins of the 

 disc black, bordered with rather conspicuous whitish rays. 

 Hind wing golden yellow, bordered with a deeply scal- 

 loped black band, which is only about i-ioth of an inch 

 wide at the ends of the veins, the base black above the 

 middle of the costal space, including the root of the cell ; 

 two (in one specimen five) black discal spots subanally in 

 the gold below, the white streaks near the veins are more 

 continuous, and the end of the cell is slightly touched 

 with whitish ; a little red at the base of the wings." 



[The inner subanal spot is 3 or 4 times the size of the 

 outer, and on the underside of the wing where they are 

 repeated they are slightly larger. The under surfaces of 

 the wings are in all respects like those above with the 

 exception that the golden yellow of the secondaries is 

 more lemon in intensity, and that the space between the 

 3rd median nervule and submedian nervure contains a 

 rather large black spot, separated from the brown that 

 occupies part of the space by golden yellow atoms, with 

 an elongate spot close to the anal angle, also divided by 

 golden scales or atoms. The sexual pouch is silky olive 

 black above, brown black below, with brown black ab- 

 dominal fringe.] 



"2. With the outer third of the cell entirely dull 

 whitish the whitish streaks between the veins coalescing, 

 and extending nearly to the outer margins, the black rays in 

 the middle of the spaces not nearly reaching the cell ; 

 hind wing very dull golden, the border wide, the discal 

 spots coalescing widely with each other and with the outer 

 black band, so as to enclose small yellowish lanceolate 

 spots in pairs, divided by the veins. Below, the hind wing 

 is dull pale whitish-yellow, without any golden tint ; this 

 area extends only to the upper subcostal vein, and 

 occupies 2-3rds of the cell. Several males and two 

 females were taken, but one of the latter was unluckily 

 destroyed, and the other is worn." 



On the Primaries the white between the veins is not so 

 much modified by dark dustings of scales as in other 

 species, and is very closely copied on the under surface of 

 the wings. The yellow of the secondaries is within the cell, 

 between the 1st and 2nd subcostal nervules, a small 

 portion of the space close to the 3rd median nervules, 

 and between that and the submedian nervure, more or 

 less whitish like the under surface. A streak of whitish 

 and dustings of whitish scales are also found on the 

 abdominal fold. 



The opaque white of the under surface of the hind wings 

 distinguishes this form from all others in the Pompseus 

 group. The affinity of this species is with P. minos, of 

 Southern India. 



There are six specimens of this species in the collection 

 of the Hon. Walter Rothschild, all that were collected, five 

 of them $ $ and one 2 , including the two types. I have 

 numbered these specimens for future reference. 



Nos. 1 and 2 have only one subanal black spot on 

 the upper side, and two on the underside : the outer one 

 being a mere dot, which can be seen from the upper 

 side in certain lights. No. 3 has three black spots on 

 the underside of the right wing, and two on the left : the 

 larger, inner one, is repeated on the upper surface, and 

 faint clouded indications of the others are visible. The 

 space between the submedian nervure and 3rd median 

 nervule contains two black spots also, the upper one 

 surrounded by black scattered scales on a whitish yellow 

 ground. 



No. 4, which I have figured in the plate, will speak for 

 itsslf (fig. 3), as will No. 5 the type. No. 6 (the ? ) also is 

 fully represented in the plate. 



$ . Head : eyes chesnut black, articulations of antenna? 

 48. Abdomen: the dorsal brown black, enclosing a longitu- 

 dinal stripe or patch on three of the segments of a red 

 fawn colour ; the lateral lemon yellow ; subdorsal redder 

 lemon. Five lateral subdorsal black dots, obscurely 

 represented. Anal valves delicate fawn colour. Pseudo- 

 neura fairly prominent in the discoidal cell of the upper 

 wings. 



Length of costa, 67 mms. ; antennae and abdomen, 28 

 mms. ; thorax with head, 19 mms. ; width of primaries, 

 36 mms. ; of hind wing, 31, and length, 42 mms. 



No. 1 $ , Length of costa, 72 ; of No. 2 <? , 68 ; of No. 

 3 71; and of var. <?, 67 mms. 



2 . Head : eyes chesnut black. Articulations of antenna?, 

 46 mms. Thorax and abdomen smoky brown ; lateral 

 parts of the latter a sordid yellow with five black dots, 

 and of subdorsal yellow. Anal tuft reddish brown. 



Length of costa, 82 mms. ; of antennae and abdomen, 

 28 mms. ; thorax with head, 20 mms. ; width of primaries, 

 each, 41 mms. ; of secondaries, 39 mms. ; and length, 

 55 mms.

I am indebted to the Hon. L. Walter Rothschild for 

 the pleasure of figuring this lovely species. 



A prominent feature of the $ S of this species is the 

 beautiful gradation of the silky golden or greenish yellow 

 of the under wings to a very green ruddy yellow towards 

 the base and interior margin. Viewed obliquely against 

 the light, the golden becomes intense.
