on the head and pronotum are generally from 14 to 16 in 

 number, thereby more fully expressing the acrseoid or 

 dananid appearance of the species ; an elongated triangu- 

 late black mark occupies 2 of the abdominal articulations 

 from the base. 



The undersurface of the Primaries with nervures and 

 rays dark brown ; the pseudoneura of the discoidal cell 

 are fairly prominent — the lower 3 united towards the base 

 as a branch, the upper is independent — a large area of the 

 wing is ochraceous grey-white ; the costa is brown ; and 

 there is a large rufous or red-brown apical area ; the pos- 

 terior wings with the base brick-red, extending a little way 

 into the cell ; the disc is brick-red, shading upwards into 

 rufous brown ; the cell is grey-white, subdued by rufous 

 scales, and the contiguous portions of the disc are treated 

 in the same manner ; the rufous brown submarginal band 

 has 7 pairs of white spots : the apical pair coalescing ; 

 the precostal nervure is broadly black — the upper branch- 

 let being immersed in a black club-shaped mark ; in the 

 cell the pseudoneura form 2 longitudinal curved black 

 lines, branching from a basal short black line, by which 

 the cell is completely divided into 4 parts. 



The thorax has a considerable number of white spots 

 on each side from the head to the base of the abdomen, 

 arranged between all the legs, which are themselves 

 striped with white on the femora, and spotted on the 

 trochanters : there is also a white spot at the base of the 

 wing, and on the base of the anterior wing costa. The 

 abdomen is orange, with lateral and subdorsal black 

 spots and quadrate marks, generally with a white spot in 

 the centre of them ; the anal segment is the same colour 

 as the rest of the abdomen. Expanse of the costa, 73 

 mms. Hab. Gaboon. 



<? . In the Horniman Museum. Wings steely blue ; 

 very silky, greenish or purplish in some lights ; the 

 Secondary submarginal band of twin spots are 12 in 

 number, with 2 minute spots at the anal angle : all steely 

 blue, but growing silvery white at the apex of the wing. 

 The Primaries with the veins all deep black : the black 

 rays irrorated on each side with black scales — the lower 

 rays very short, and merging into a black irregular mark. 

 The subcostal band is black, with a delicate ray of 

 greenish-gray scales ; the apical black area less than in 

 the preceding example, which appears to be the normal 

 characteristic. The secondaries with the submarginal 

 black band narrower than in the last example, and blended 

 into the blue by blue atoms between the veins and rays. 



Under surface. Primaries grey bluish-white, showing 

 in a strong light a warm blush towards the outer margin ; 

 a short dark line obliquely from the distal end of the cell ; 

 base of the wings clouded with black atoms ; the sub- 

 median fold is black at the base, and along its whole 

 length is placed a little below the black submedian ray : 

 the costa is black, and apical area fuscous brown. The 

 posterior wings differ very little from the preceding- 

 example, except that the brick-red area from the base is 

 rather more extensive. 



Length of costa, 79 mms. ; greatest width of Primary 

 wing, 46 mms. ; length of secondary wing, 50 mms. ; 

 width, 36 mms. [The third subcostal nervure begins at 

 the apex of the 1st discocellular nervule.] Length of 

 antenna? or abdomen, 25 mms. ; of thorax with the head, 

 1 1 mms. ; eyes and villose tuft prominent. [The antennae 



are shorter in proportion to the wing, than in most of the 

 Ornithoptera.]

<? . In the author's museum. Wings a slightly greener 

 blue, but very blue towards the apex : apical area of black, 

 less extensive than in the preceding ; the secondary wings 

 with the black submarginal band interrupted by green- 

 blue atoms, which make the blue of the wing nearly 

 continuous with the blue submarginal twin spots, and give 

 nearly all the black rays the aspect of an oval black mark 

 on the lower part of the ray. On the underside the cell 

 of the posterior wing is whiter than usual, but otherwise 

 there is no important difference. Length of costa, 80 

 mms. Hab. Congo. 



<? . In the author's museum. The submarginal row of 

 twin spots on the posterior wing much smaller and 

 orbicular. Underside, with the base, and the whole of the 

 cell clouded with dark atoms ; the cell of the posterior 

 wing is unclouded grey, but the fuscous brown of both 

 wings is darker. Length of costa, 80 mms. Hab. 

 Calabar. 



There are 6 $ S at present in the British Museum, 

 excluding the Hewitsonian type. <? . The browns 

 of the under surface chestnut brown ; the posterior wing 

 submarginal band is reddish black, the light twin spots 

 well expressed. Hab. Cabinda, N. of the Congo.

 blue. Hab. Old Calabar.

 surface of the hind wings nearly entirely suffused brownish- 

 red. Hab. Cabinda. 



a . Ibid. Very violet-blue on upper wings ; the inter- 

 nervular rays not so stout as on the lower wings. Hab. 

 Calabar. 



Examples from the Cameroons do not differ materially. 



The British Museum does not possess a 2 of this 

 species, although the Godman and Salvin series is now 

 amalgamated with the national collection. Prior to the 

 late Mr. Hewitson's death, he became possessed of other 

 examples of this species, and consequently the Hewitsonian 

 collection in the British Museum contains 5 specimens, 

 including the type, which are all males. 



Apropos of the colour resemblance of this species to some 

 of those of the genera Romaleosoma and Euryphene (notably 

 R. ravola, Hew., R. cutteri, Hew., R. -ruspma, Hewit., and 

 R. luperca, Hew., all from Old Calabar; R. Zampa, 

 Westw., from Sierra Leone ; R. rezia, Hew., from the 

 Gaboon; E. carshena, Hew., and E. phranza, Hew., from 

 Old Calabar ;E. lesbonax,~He\v.,hom the Niger; E.eliensis, 

 Hew., from the Gaboon, with several others) we find 

 several species of the Nereus group of Papilios assuming
