AMBLYPODIA GEOUP OF THE LY(L£N1D,E. 35 



Var. eibbei Rober. 



6 . Upperside rich purplish or violet-blue ; primaries with very narrow black 

 costal and posterior margins ; secondaries with broad blackish costa and very narrow 

 outer margin ; tail moderately long, stout, black, tipped with white ; lobe slightly 

 developed. Underside exactly as in amytis Hew. 



? . Upperside paler than the male and more violet in tone ; primaries with very 

 broad costa, and much broader posterior margin and apex ; secondaries with very 

 broad margins all round. Underside exactly as in amytis Hew. 



This insect is evidently a local form of Hewitson's species amytis, but it differs in the 

 deep tone of the blue of the upperside, and the very narrow margins of the males. I 

 have specimens of it before me from Aru (the types), Tokal Key, one male from 

 Waigeoe, and one male from Ati Ati Onin (New Guinea). Miskin has also recorded 

 two specimens of it from Cape York under the name cryonthe, but, as Rober described 

 it two years previously, Miskin's name falls. Amytis is somewhat variable as to the 

 tone of the blue, and decidedly variable as to the pale subcostal streak on the underside 

 of the secondaries, which is subject to obsolescence. I have several specimens in which 

 it is practically obsolete, and many where there is only a slight trace of it, and these 

 forms occur irrespective of locality. 



Through the kindness of Mr. H. Druce, I have been able to examine some specimens 

 from Fergusson and Woodlark Islands, all of which have no trace of the pale sub- 

 costal streak ; one female from Fergusson Island is unusually large and robust.

d . Upperside : both wings brilliant silvery morpho-blue, purplish at the costa and 

 apex of the primaries, which have a very narrow costa, rather broader posterior border 

 of black ; the secondaries have a broadish black costa, narrow black posterior margin, 

 and dark grey abdominal fold ; the tail is long, stout, and white-tipped, and above it 

 at the end of the second median nervule is a tooth-like projection. Underside : both 

 wings very dark ; the primaries have three discal spots traced out by silvery-bluish 

 edges, almost obsolete as to the internal edge of the third spot, which has a pale outer 

 edging ; otherwise the ground is very broadly quite pale, with more or less of a lilac 

 suffusion, the paleness extending throughout the submediau area. Below the second 

 and third discal spots are two other obscure spots divided by the lower median nervule. 

 The transverse band in the middle of the pale area is continuous, slightly curved, 

 broadish, and generally slightly tapering narrower to the lower median nervure, where 

 it terminates ; it occasionally has a distinct bend or angle. Submarginal row present 

 as usual. Secondaries: the basal three-quarters of the wing very dark indeed and
