bat the black spots in it approach its onter edge more closely, flilia on both wings 

 grey. ' 



Female. — Upperside: both wings dasky fdiginons grey. On the anterior 

 wings the pale central area is much more restricted and more densely irrorated by 

 dusky grey scales. On the posterior wings there is scarcely any trace of the pale 

 subbasal area of T. henyis and T. icallucei, the wings being only slightly paler 

 towards the base and the upper part of the inner margin. 



Underside : differs from T. heiu/is as follows : on the anterior wings the black 

 costal and outer-marginal band is much broader, covering nearly the whole of the 

 cell, and extending broadly along the outer margin to the outer angle. On the 

 posterior wings tlie white band is rather narrower and more sinuate on its onter 

 edge. Cilia of both wings more dusky. 



Expanse of wings : If inches.

In the Tring Museum and Mr. Grose-Smith's collection (types cJ, ?). A good 

 series of both sexes was sent. 



6. Thysonotis helga sp. nov. 



BIale. — Upperside : both wings rather brighter blue than in T. horsa. Anterior 

 wings with an indistinct patch of white scales in the middle of the disc ; costal 

 margin narrowly and onter margin more broadly black than in T. Jiorsa. Posterior 

 wings with a broad snbbasal white band crossing the wings, with a basal band 

 of blue; a broad outer-marginal black band, broadest towards the anal angle, not 

 indented on the veins, and extending at the apex along oue-third of the costal 

 margin ; the blue area crossing the disc between the white band and the outer- 

 marginal black band is more restricted than in other allied species. 



Underside: with the costal and onter-marginal black band broader than in 7". 

 horsfi, extending over the cell and a little below it, and more broadly along the onter 

 margin to the onter angle, the white central area being corresjiondingly more 

 restricted. Posterior wings with the central white band broader, and the sub- 

 marginal azure-blue band narrower, the black spots in the blue band being less 

 elongate. Cilia of both wings narrowly white, crossed with black at the ends of 

 the veins. 



Female. — Upperside : both wings blackish brown. Anterior wings with a con- 

 spicuous oblique broad white band, diffused outwardly, extending from a little above 

 the uppermost median nervule, and slightly invading the cell, to the basal half of 

 the inner margin. Posterior wings with the inner half white and dusky at the base. 



Underside : anterior ivings with a costal and onter-marginal broad black band 

 of uniform width, centred by a pale azure-blue band, which extends from the base 

 round the wings nearly to the outer angle, the rest of the wings white. Posterior 

 wings as in the male, but the inner edge of the black outer-marginal area is more 

 regnlar. 



Expanse of wings : c? li, ? If inches. 



JJa/j. Ansus, Jobi Island (W. Doherty, April and May 1897). 



In Mr. Grose-Smith's collection (types c?, ?) and in the Tring Museum. 



7. Thysonotis lamprosides sp. nov. 



Male. — Uppeiside: both wings very closely resemble 3". lampros Druce, but 

 the white baud on the posterior wings is comparatively narrower and more sharply
