hitherto referred to the Genus lolaus. 145 



the most brilliantly coloured species of the group, and Hewit- 

 son's figure does not do it justice. It is, I think, doubtful 

 whether the insect referred to by M. Oberthiir can be placed 

 under this name.

^. Allied to A. iulus, Hew. Upperside paler and less 

 brilliant blue ; primaries distinctly whitish at base of the 

 costa : secondaries, cilia pure wliite ; a dark red spot, below 

 which is a small black one occupying the upper half of the 

 lobe, the lower part being white, with a narrow black line at 

 the margin ; tails pure white, with a narrow black central 

 line. Underside creamy white ; primaries with costal mar- 

 gin and apex slightly fulvous ochreous : secondaries with a 

 well-marked orange band, thickening slightly at each nervule, 

 running from the apex to the anal angle, where it converges 

 into the usual anal reddish-orange patch, and connected with 

 a patch of the same yellow (having a black spot in centre) 

 between the lower median nervules; a narrow broken zigzag 

 line running from near the apex inside the yellow band and 

 reaching to the inner margin, where it is rather more distinct; 

 a deep black spot, with a few blue scales under, in the lobe, 

 and on the anal orange patch are a few pale lavender scales. 

 A narrow black marginal line from the apex to the anal angle 

 and down the centre of the tails ; cilia white. 



Head white ; thorax greyish ; palpi white below, black 

 above, and black-tipped ; legs white ; antennas black, spotted 

 with white beneath. 



Expanse 2 inches.

This is evidently a distinct species from A. iulus, Hew., to 

 which it was referred by Messrs. Godman and Salvin in the 

 list of butterflies collected by the late Mr. Jameson (' Story of 

 the Rear Column,' p. 442, 1890). It is a different shade of 

 blue. The specimen has a label attached, " Yambuya Camp, 

 Jameson."

I am not certain that this species is correctly placed here.
