fusiform, tapering from the head backward, yellowish black in 

 general color, with large black markings from which arise long, stiff 

 hairs. With each successive molt the black markings become pro- 

 portionately smaller and the yellowish markings more pronounced. 

 The mature larva has the body somewhat flattened and nearly equal 

 in width throughout, the hairs becoming fewer in number, shorter 

 and lighter in color. A full grown larva is about half an inch in 

 length and has a wide dorsal stripe of yellow, with a lateral stripe of 

 the same color on each side. The greater part of the head and legs 

 and the posterior portion of the last segment of the body are black. 

 In Fig. 1, gr, a larva is shown enlarged, and on a leaf several are 

 represented as feeding. 



As soon as the young are hatched, they begin to feed, which they 

 continue to do for about two weeks, but as the eggs do not all hatch 

 at once, the larvae may be found on the trees for a much longer
