A QUEER LITTLE FAMILY ON THE BITTERSWEET 91 



But the little harlequin is as wary a bird as he 

 was a thorn ! No sooner do we touch his head 

 with our finger than with an audible " click " he is 

 off on a most agile jump, which he extends with 

 buzzing wings, and is even now perhaps aping a 

 thorn among a little group of his fellows some-

 thus enlarged it is difficult to get entirely rid of 

 the idea of a bird. I have shown a group of the 

 insects in various attitudes, the position of the 

 eyes alone serving as a starting-point for our 

 comprehension of his singular make-up. The tall 

 neck-like or thorn-like prominence is then seen to
