pinkish brown, some clear fawn-color, others chocolate- 

 brown, and one was almost black, growing purple- 

 brown as it grew larger, as if the color were diluted to 

 cover the increased surface. Each had a dark dorsal 

 line, lighter broken subdorsal lines, the first five seg- 

 ments speckled with black, the sixth to tenth segments 

 having two black dots each on the dorsum and a few 

 on the venter ; all were lighter in color on the dorsum

 more brown than green caterpillars. 



Both species now ate voraciously and grew very 

 rapidly. They are very satisfactory crawlers to rear, 

 for they are not delicate, do not hurt each other, and 

 have no unpleasant ways. Their boxes give out an
