hesitate to name them, preferring to consider them, at any 

 rate for the present, as forms of virilis. In mosl of them 

 the upper discal K.W. blue spots (whitish in one example) 

 are distinct in areas 2, 3, 5, and 6, being the most prominent 

 markings on the wings except the submarginal white .spots 

 of the II. \\\. the only markings that are not blue in most 

 specimens. The F.W. post-disca] spots can generally be 

 made out, although very faint. The blue band of the K.W. 

 is more outwardly placed than in carpenteri, although very 

 similar in its angulated direction : within it the H.W. as 

 well as the basal third of the F.W. is a steely blue of great 

 brilliancy in certain lights in some of the specimens. The 

 females differ from virilis and many other female forms in 

 the faint linear development or absence of red in the ad- 

 marginal spots of the H.W., which are peacock blue (in one 

 female pale grey), generally bacoming olive green at the anal 

 angle, but sometimes persisting unchanged. The upper sur- 

 face markings are very elusive and very variable. Although 

 developed to a much fainter degree they greatly resemble 

 those of carpenteri, a form which could probably be easily 

 derived from variable male-like females such as these. 



Now that Mr. Swynnerton, (apt. Lamborn, Mr. Farquharson 

 and the Rev. K. St. Aubyn Rogers (who in 1916 bred the 6* 

 and what is probably the 9 form a of ethalion from a known ° 

 parent of the same form, at Dabida) have shown that it is 

 not difficult to real- these most interesting of all species of 

 Chqraxes, it is to be hoped that more will be done in breeding 

 from known female forms in the same and other localities. 

 It may perhaps be possible to pair in captivity and thoroughly 

 test the Mendelian relationships.
