SPOLIA ZBYLANICA. 



VARIATION OF "CATOCHRYSOPS PANOAVA," 



Horsfield. 

 By N. Manders, Major, R.A.M.C. 



/ 



A SERIES of five males and ten females of this Lycaenid 

 -^--^ Butterfly, reared by Dr. Willey, and submitted to me with 

 the remark that they were hatched on July 4, 1902, from larvae 

 collected from a species of Cycas in the Museum grounds, show 

 an aberration which is especially noticeable in the females, and 

 is worthy of record as an example of non-seasonal variation. 



The five males are of the ordinary rain season form, and do not 

 vary on the upper side of the wings beyond an intensification of 

 the dark pigment inside the posterior border in three of them, 

 giving rise to dark lens-shaped spots, which are not conspicuous in 

 the other two specimens. 



The females are also of the rain 

 season form, and present an interesting 

 series showing gradual diminution of 

 pigment in the posterior margin of tbe 

 hind wing. Two of them may be 

 regarded as typical examples of the 

 species C.pandava ; four of the others 

 show a whitish suffusion of the pos- 

 terior margin on the upper surface 

 between the veins and above the black 

 lunules, but separated from them by 

 some blackish scales. 



In the remaining four females the 



black lunules are entirely replaced by 



white, the veins however remaining 



black ; the whitish suffusion above the 



lunules has become concentrated into 



^'f^lrl^ . lwi';jf:S;^Z definite white lunules, though not of so 



of variation in thesubmarginal clear a white as the marginal lunules; 



pigment spots of the hind 



wing. the blackish line between the series of 



outer and inner lunules still persists. In all these specimens the 

 black lunule or ocellus external to the tail-like appendage of the
