spots below nearly obsolete ; the space between the lowest median nervule and the 

 inner margin almost devoid of scales over the basal three-fourths. Posterior wings with 

 the white band as above, edged on each side with greenish blue, a streak on the costal 

 margin at the liase, and another below it along the costal nervure, two submarginal 

 bands divided by the veins and ^ narrow streak just before the outer margin, all 

 greenish blue. 



The female resembles the male, but the wings are rounder, and the spots and 

 band are larger and wider. On the underside the greenish blue gloss extends in some 

 lights over the whole of the wings. 



Expanse of wings : 2J inches. 



A long series of this is in the collection. It is neare.st to N. venilia Linn, and 

 N. brebissonia Boisd.

A long series from Biak, Korrido, Joliie, and Humboldt Bay. 



113. Neptis anceps sp. nov. 



Male. — Upperside: both wings dark brown. Anterior wings with two minute 

 blue spots in the cell, two beyond it between the lowest subcostal and upper 

 discoidal nervule, the outermost centred with white and a triangular blue patch, 

 having its apex between the two uppermost median nervules, and its base on 

 the inner margin about its middle, a submarginal row of eight white round spots, 

 tlie lowest almost obsolete. Posterior wings with an irregular blue bar before the 

 middle, commencing below the lowest subcostal nervule, where it is narrowest, and 

 becoming wider towards the inner margin when it becomes pale ; a submarginal row 

 of small white sjiots, those in the middle the .most distinct. 



Underside brown, with three spots in the cell and one beyond, and an indica- 

 tion of a second and a submarginal row of spots ; all the spots larger and more distinct 

 than on the upperside and faintly tinged with blue, a grey streak and a few scattered 

 grey scales at the base. Posterior wings with a grey streak, followed closely by a 

 broad grey band extending partially down the inner margin at the base, and a sub- 

 marginal row of bluish white spots larger and more distinct than on the ui)perside ; 

 incisions on both wings dotted with white. 



Expanse of wings : 2 inches. 



I have considerable hesitation in di'scribing this as a species distinct from 

 N. veniliii, but the wings are shorter and broader than that species. In some of the 

 inuks there are white .spots in the blue bands, varying in size and number, but in no 

 specimens so wide as the white spots in the blue bands on N. venilia, and on the 

 underside of tlie jiosterior wings the bands which cross the wings are narrow. 



114. Neptis gauina sp. nov. 



(1-1. ML, fig. 4.) 



Male. — Upperside dark brown, faintly tinged with purple. Anterior wings 

 with two indistinct violaceous grey spots ))laced obliquely between the lowest subcostal 

 and upper discoidal nervules, and a submarginal row of similar indistinct spots more 

 or less ob.solete. Posterior wings without any markings. 



Underside: lioth wings purplish brown, paler than on the upjierside. Anterior 

 wings with two spots in the cell, that nearest the base indistinct, and a ])ale brown
