The Green-Striped Maple-Worm, Anisota (Dryocampa) 



rubicunda. Lot 325. 

 So numerous upon the maple have been these caterpillars for 

 two seasons, in many cases entirely defoUating the trees, that the 

 following description and accompanying illustrations are given. 

 "The larva measures when full grown about one and one-half 

 inches. It is pale yellowish green, striped above with 8 very 

 light, yellowish-green lines, alternating with 7 of a dark green, 

 to black. There are two prominent spines on the second 

 thoracic segment, and two rows of spines on each side of the 

 body, one above and one below the spiracles, and on the 8th and 

 9th abdominal segments there are four prominent dorsal 



spines." ^' 



The species passes the winter in the pupa state and pupae were 

 commonly found in the same ^situations as those of the saddled 

 prominent under the fallen leaves in the infested maple growths. 

 The moth which emerges in the spring (for Maine about the 

 first of June) is an exquisitely beautiful moth with wings of 

 pale yellow banded with rose pink. 



Symmerista (Bdema) albifrons. 

 The White Tipped ]\Ioth. Lot 386. Among the forest cater- 

 pillars this season, the larva of this moth was very common. 

 This caterpillar was taken on oak, birch and other trees. "It 

 is smooth and shining, with no hairs. Along each side of the 

 back there is a yellow stripe, and between these, on the back, 

 fine black lines on a pale lilac ground ; on each side below the 

 yellow stripes there are three black lines, the lowest one just 

 above the spiracles. The head is orange-red ; and there is an 

 orange-red hump on the eighth abdominal segment." (Professor 

 J. H. Comstock-Manual). The conspicuous orange-red at each 

 end of the caterpillar together with its rather peculiar shape 

 make it a little puzzling to tell whether one of these caterpillars 

 is traveling backward or forward.
