184 HELICOPIS GNIDUS. 



Caterpillar thickly clothed with soft hairs, the chry- 

 salis suspended by the tail, and having a band round 

 the middle. 



The best known and most common species of this 

 genus is H. Cupido, which is rather smaller than 

 H. Gnidus. The former is commonly named the 

 Golden-spot, and the latter the Silver-spot Butterfly.
