7th and 8th abdominal segments, there is freqviently a large 

 reddish area. Furthermore, this caterpillar has on the 2d tho- 

 racic segment, just behind the head, a pair of long, black spines, 

 and on the posterior extremity shorter, stout spines on the loth 

 and nth segments. These spines are represented on the inter- 

 vening segments by minute, black points arising from similar 

 tubercles. There are also two lateral rows of short spines 

 similar to the smaller ones in the submedian dorsal lines ; the 

 ventral spines being decidedly larger. Spiracles rather large, 

 black. 



The eggs, according to Professor Riley, are deposited in

 states that it rarely feeds on oak in nature. The attack at 

 Berlin was confined almost entirely to sugar maples, though a
