Effect of Cyaxide upon Colour. 

 — A very curious case of artificial col- 

 ouring in a butterfly has been sent me 

 by a friend. He says that the speci- 

 men, a male Gonopteryx \_sic\ rhanini, 

 was placed in a spare cyanide bottle, and 

 left undisturbed for two years ; l)ut that, 

 at some intermediate time, the st<)])per 

 was tampered with and not properly 

 replaced, so that air was introduced. 

 The result is. thai the butterfly is richly 



coloured with crimson along the costal 

 area, and partially round the other mar- 

 gins of the fore-wings, and lias large 

 blotches of the same on the hind-wings. 

 Indeed, the only portion of the wings 

 w hich is left entirely of the usual brim- 

 stone colour is that portion which, in 6". 

 cicopatra. is clouded wltli crlvison. —
