a 9 



In a ? in the author's collection the superior cellular 

 patch is nearly as if the upper half had been cut away in 

 an oblique direction, only the faintest indication of it in 

 white being left on the brown. The other white marks of 

 the wing are all larger and more prominent, every neural 

 space containing one or two. 



Plate X., fig. 3, represents a var. of the 2 in 

 the British Museum, in which the discoidal patch is so 

 large as to suggest that it might belong to 0. Cronius. 

 The best portion of the patch is creamy white subdued 

 by grey atoms, the clouded part with grey atoms on a 

 smoky brown. The submarginal parts of the patches of 

 the inferior wings are suffused with a golden olive 

 yellow ; the intra-submedian space contains a black spot 

 covered with grey scales ; the central thoracic stripe is 

 emerald green ; the abdomen grey yellow, with an orange- 

 lemon beneath. Length of costa ioo mm. 



Hab. Wokau, Aru Islands. 



Fig. I, PL X., is also of a ? in Brit. Mus. 5 mm. 

 greater in costal length, with a sharply serrated subquadrate 

 discocellular patch, and considerable variation in the 

 other markings of the upper wing. Hab. Aru Islands. 

 A much smaller 2 in the same collection appears as 

 fig. 2 in which the elongated marks outside the cell are 

 very important and large, and in the space bounded by 

 1st and 2nd median nervules, in addition to the elongated 

 irregular-edged mark, are two small submarginal spots, one 

 within and nearest to the larger mark. These are all grey 

 on a brown ground. The whites of the inferior wings are 

 all ochreous grey ; and this individual also suggests a 

 close resemblance to 0. Cronius. Its Habitat is the 

 Aru Islands, but which of them is not indicated. 



<? . In Brit. Mus. Green on median vein only faintly 

 seen ; 3 black spots on the under wings. The costal 

 band of the Primaries seen against the light is a purple 

 green, suggesting the colour of P. Urvilliana; the general 

 green is bluish. Opposite the light, it is a warm yellow 

 emerald, almost golden in the centre of the secondaries. 

 On the under sides silvery bluish green ; hind wings warm 

 silvery green ; markings nearly the same as those in our 

 figure. The black of the costa is shot with a silvery 

 purple gloss. Length of costa 78 mm. Hab. Wokau, 

 Aru Island. 



$. In Brit. Museum. Greens, dark vegetable; against 

 the light very dark olive, opposite light only emerald 

 green with a slight warmth ; salmon-coloured reflections 

 even on the black. Spots of Secondaries 3 ; on the under 

 side 6. In the cell of the upper wing on the under surface 

 all but a broadish mark nearest the costa, 2-3rds of length 

 green ; colour of under sides against the light not a very 

 warm yellow. 



PL X., fig. 5. Green on upper side of the Primaries 

 only on the median nervure, and slightly down the 

 nervules. Length of costa 88 mm. Hab. Aru Island. 



$ . Brit. Mus. A much warmer golden green ; 4 spots 

 on the lower wings, the lowest only faintly produced by 

 atoms ; on the under side 7 black spots, the 7th in 

 ochreous yellow. (The under side very golden green.) 

 Other markings, except in one respect like those of our 

 fig. on PL IX. The same Habitat. 



<? . In the Hewitson coll. With 2 spots only on the 

 hind wings. The green is beautifully dusted with black 

 atoms, growing denser at the base. This and another 

 example are placed together as vars. poseidon, and 

 aruanus of PRIAMUS — the latter from New Guinea, or 

 Waigiou. Length of costa yy mm. All the greens are 

 very golden. The 2 is of the ordinary type, with a costal 

 length of 102 mm. 



In the S figured by Dr. Fickert in his paper (fig. 3, 

 PL xx.), the discocellular green mark on the under surface 

 of the anterior wing extends the entire length of the cell, 

 all but a fraction, with a width generally more than half 

 that of the cell ; and the costal length of the wing is 

 83 mm. 



It will not be difficult in another part of this work to 

 show that aruana, poseidon, and pronomus are only local 

 varieties of a sub species of Priamus, and that, at any rate, 

 the two former are identical in specific value. 



PL 9, figs. 5, 6, represent varieties, one in the British 

 Museum, and one in the author's collection. PL g, figs. 

 3#, 36, give the exact shape of the costal band and the 

 sexual patch of a variety in the author's collection. 

 PL 10, fig. 12, the shape of the abdominal fold of the ? , 

 and fig. 13 of the $ drawn flat, or only partially closed.
