While the local variations of this species may be 

 broadly divided into distinctly recognised types of colour, 

 as blue and blue green ; if a long series of the 3 are 

 brought together from the different localities in which 

 they were found, a multitude of connecting graduations 

 of tint will be presented, ranging from extreme violet 

 to extreme green blue. The undersides will also present 

 a number of variations of tint on both wings. The 

 amount of variation in the number, size, or shape of the 

 spots, or the extent of black dusting of the upper surface 

 of the hind wings, will differ in each example. Whether 

 the extreme manifestants of these colours are ever to be 

 found flying together in company it is not yet possible, 

 though it would be interesting, to know. As our know- 

 ledge at present stands the green forms are chiefly con- 

 fined to New Britain and New Ireland ; the blue forms in- 

 habit certain of the Solomon Islands, the New Hebrides 

 (?), and New Guinea. The females vary very much in 

 depth of colour (from light to dark), and number, shape, 

 and size of markings : this is especially the case with 

 respect to the discocellular patch of the upper wing — 

 it being very large in some, and almost obsolete in others. 

 [See PI. 17, figs. 5, 6, 7.] 



I may mention also that in New Britain the 2 2 of 0. 

 Aruana are difficult to separate from those of Urvilliana, 

 if a series of the two are mingled together, one of the chief 

 distinctions being the yellower tone of the under-surfaces 

 of 0. Aruana. 



On PI. 17, figs. 2, 3, are portraits of a tolerably 

 extreme green blue example of the 3 , which comes pretty 

 near the var Bornemanni of Pagenstecher, which I had the 

 privilege of figuring from the museum of Dr. Francis 

 Walker. It has the typical markings on the hind wings : 

 its vivid blue green is so intense, uniform, and silky when 

 viewed opposite the light, as to suggest a close affinity 

 with 0. Eumceus, the hind wings exhibiting the greatest 

 amount of golden tint ; against the light the hind wings 

 are greenish violet, the outer-marginal band of the front 

 wings opalescent violet, and the subcostal band a dead 

 undefined green. The amount of black on the hind 

 wings also causes them to appear, when viewed obliquely 

 in any direction, almost entirely and intensely velvety 

 black. The markings of the underside are most nearly 

 like those of 0. Priamus. Length of the costa, in a 

 direct line, 81 mms. 



3 . In the collection of the British Museum (ex God- 

 man and Salvin collection), primaries a rich violet. The 

 submarginal terminals of the veins and folds are so 



strongly expressed and arranged, that the submarginal 

 band, instead of being continuous as in many other 

 examples, is caused to appear as a band of strongly 

 lunate blue spots. This specimen, with an accompaning 

 2 , is labelled New Hebrides ? 



3 . Brit. Mus., ex Godman and Salvin coll. Centre 

 of hind wings light blue on the undersides. Habitat, 

 Florida Island, Solomon group. 6 3 3 and 3 ? 2 collected 

 by Mr. Woodford from this locality are in the collection. 



3 . Brit. Mus., ex G. and S. coll. Rather lightish 

 blue ; the submarginal row of black spots on the under- 

 surfaces very large and varied. 2 , large and light in 

 colour. Hab. Aola, Guadalcanar: Solomon Islands. 



3 . Brit. Mus., ex G. and S. coll. The blue delicate 

 in tone ; the spots medium size ; the wings not so in- 

 tensely dusted with black atoms. Hab. Fauro Island : 

 Solomon Group (Woodford). 



2 . The discocellular mark of the primary wings 

 almost obsolete. 2 , with the same mark rather obscure, 

 the wings are also very melanistic on the upper surface. 

 Hab. Fauro Island : Solomon Group (Woodford). 



2 . Small example, light brown ; marks very light, and 

 larger than in the preceding. Hab. Fauro Island : Solo- 

 man Group (Woodford). 



$ . Same collection. Colour ranging from violet to 

 green, according to the light. Underside of primaries 

 blue, of secondaries golden green and blue green ; the 

 black spots all large. Hab. New Ireland. 



3 . Brit. Mus. Secondaries with four small orbicular 

 spots, the fourth almost obsolete. Hab. New Ireland. 



3 . Brit. Mus. ex G, and S. coll. (two 3 3 and six 

 2 2 ), var. Bornemanni, Pagenst. The costal band of the 

 primaries is golden green from the base to the blue 

 green at the apex ; secondaries, greenish blue ; the spots 

 are medium size ; the cell black : between the veins much 

 dusted with black atoms — the cell slightly dusted with green 

 atoms ; some blue atoms on the black borders ; under- 

 surface of secondaries golden greenish ; of primaries, gol- 

 den greenish-blue. 2 2 with large discocellular marks. 

 Hab. New Britain.
