" Kandy and Galle. Gomnaon " (Wade). 



" Found all over the island, predominating in the low countiy. Very difficult 

 to capture perfect. March and April principal time for emergence from chrysalis " 

 (Mackivood) . 



" Darts rapidly through the air, alighting on the ruddy foliage of the Hibiscus, 

 or the dark green foliage of the Citrus, on which it deposits its eggs. The larva has 

 a hump on the fourth or fifth segment, and from this hump, on being irritated, it 

 protrudes a horn of an orange colour, bifurcate at the extremity, and covered with a 

 pungent mucilaginous secretion, and strikes it upon the offending object with 

 unerring aim " (Emerson Temient).
