SLEEPING POSITION OF THANAOS TAGES. 



THANAOS TAGES. 



On the evening of June 12th last, when searching for Lyccsna 

 medon and L. icarus, of which I found several at rest on the 

 heads of grasses, I noticed one grass head which seemed rather 

 weighty, with what I at first took to be some kind of Noctua at 

 rest ; but, on closer examination, found it to be Thanaos tages at 

 rest. The wings were held in exactly the same position as a 

 Noctua when resting. The anterior wings entirely covered the 

 posterior wings, the head bowed so as to touch the grass, and 

 antennae bent back parallel with the costal margin of the wings. 

 The colours of both butterfly and grass head upon which it 

 rested were of wonderful similarity ; and, coupled with the 

 position taken up on the brown tuft, was a remarkable and 

 perfect disguise. 



Having my sketch-book with me at the time I was able 



to make a sketch of it on the spot, from which the above 



drawing was made.
