HARRISIMEMNA TEISIGNATA 



GENUS, HARRISIMEMNA. 



SPECIES, trisigna'ta (" thrice-marked "). 



The first sight of this queer caterpillar is usually mis- 

 leading, for the cast masks which adhere to the long 

 hairs over the head are of a dirty orange-color, and 

 look like drops of decayed animal matter, while the 

 black, white, and dirty yellow of the caterpillar and 

 its shaking and waggling from side to side make it 

 look like a mass of unpleasantness, and it needs a 

 second look to show that it is alive. It may be found 

 on spiraea, lilac, and other shrubs. When disturbed it 

 hangs as in B, and gives its body a most peculiar mo- 

 tion, utterly unlike any other living thing we have ever 

 seen. Gibson gives an excellent description of it in 

 one of his Ijooks or magazine articles. 



The sketches given here were taken from the first 

 caterpillar we found, just before it bored into a bit of 

 rotten wood to pupate.
