 caterpillar with black intersegmental bauds and long branched spines, a species 

 of Automeris, some of the black bands of which appeared to be swollen. To his 

 amazement these swellings, when touched, quickly slid over the back of the 

 caterpillar to the other side with the hurried motion of a Pyralid larva, and 

 indeed turned out to be small lepidopterous larvae as black and glossy as the 

 bands of the Automeris caterpillar.
