IXCXNIDJR. 267 



Thysle occurs as far West as Caledon.* I anticipate information on the 

 subject as regards portions of the intermediate ranges of country, which 

 will probably further elucidate this point. 



Sandy hill-sides and broken ground, chiefly near the sea. 



September (m) April (e). 



Nothing can exceed the brilliant beauty of a blue-glossed specimen of 

 this exquisite little butterfly, as it settles in the bright sunlight on the white 

 sand, or on the deep-green fleshy leaves of the Meserabryantheraum. My 

 first introduction to Thysbe took place at Mossel Bay on the 20th September, 

 1858, and there was never a more decided case of " love at first sight." 

 The species was very numerous there on the sand-hills near the beach, but 

 I regret to state that I only captured three specimens, expecting to see a 

 like profusion at Knysna. At the latter place I only beheld three Thysbe 

 proper in the space of nine months ! This mournful case should prove a 

 warning to collectors of natural objects never to overlook a species because, 

 on their first encountering it, it appears abundant. Many animals and 

 plants are so local that years may elapse before a second opportunity of 

 obtaining specimens occurs.
