Bolivar gives a very brief description of the species, 

 under the name received from de Saussure. The speci- 

 mens in the Brunner collection are named " hrunneriana" 

 but there can be no doubt that de Saussure changed his 

 name on publishing the description. In the meantime 

 Bolivar had gained priority and his name must stand. 

 The specimens in the Brunner collection named " hrun- 

 neriana " by de Saussure agree perfectly with the latter's 

 description, and there is no doubt as to the correctness of 

 the synonymy. 



It varies considerably in size and intensity of colour. 

 The male is very markedly smaller than the female.
