JSTEW INDO-MALAYAN BUTTERFLIES. 329 



Hindtving with the usual spots scattered over the disc, but all very- 

 small; a marginal series of seven small round prominent spots. 

 Female. TJpperside, foreicing with the outer black margin very 

 much wider than in the male. Hiniiving with the costa broadly 

 dusky. Otherwise similar to the male. 



Perhaps nearest to C. ahasa, Horsfield, from South India, Ceylon, 

 Java, and Sambawa, from which it differs in the far greater extent 

 and different shade of blue on the upperside, and the narrower outer 

 black border to the forewing : the two species agree absolutely on 

 the underside. It is also near to G. aWoccendeus, Moore, from the 

 Khasi Hills and Himalayas, but has more blue coloration and a 

 narrower black border on the forewing on the upperside. 



At present the genus Cyaniru is represented in my collection by 

 five species only from Java, viz. : — 0. akasa, Horsfield, C. puspa, 

 Horsfield, C. huegelii, Moore, apparently identical with Western 

 Himalayan specimens, G. coalita, de Niceville, and C. ceyx^ de 

 Niceville. Mr. Doherty speaks of capturing seven species in the 

 mountains of Eastern Java.* 



C. ceyoc is described from two male and one female specimen sent 

 to me by Heer M. C. Piepers.

 broadly black, the abdominal margin fuscous ; the anal lobe small, 

 black ; the tail moderately long, black tipped with white. Under- 

 side, both wings dull fuscous- or hair-brown, without any gloss, all 

 the macular markings but very slightly darker than the ground-
