with the wind. The ends are neatly tucked into the somewhat tight roll till 

 a compact, cylindric, nearly solid mass of vegetation is formed. Before the 

 entire leaf is rollecl, she deposits a single egg, rarely two, in the middle 

 next to the midrib, where it lies loosely in a little cavity. The egg 

 hatches in about a week. 



Eight-spotted forester 



Alypia octomaculata Fabr. 



Reddish, black-ringed caterpillars about x}i inches long, feed from June into August 

 on Virginia creeper and grapevine. 



This rather common insect is occasionally quite injurious to Ampelopsis 



or Virginia creeper, and it is also a grapevine pest. The caterpillar is 



easily recognized by the above characters and can be readily controlled by 



spraying with an arsenical poison wherever this measure is practical. The 



parent insect is a beautiful black moth with eight lemon yellow spots on its 



wings, which latter have a spread of i^ inches. 



Rose beetle 



Macrodactylus subspinosus Fabr. 



This familiar species is a well known pest of roses and needs no descrip- 

 tion. It is particularly abundant on sandy soils, where it sometimes occurs 

 in immense numbers. Grapevines and rosebushes in particular suffer from 

 its depredations, though it is almost equally injurious to apple, pear, cherry, 

 peach, plum and most other fruit trees as well as some forest trees. A few 

 specimens were taken on hard pine at Karner in June 1901, and it was 

 abundant the following year on scrub oak. 



There is probably no better way of protecting valuable plants from 

 the ravages of this voracious insect than by covering them with mosquito 

 netting. 



Calligraphus lunata Fabr. was found eating wild rose blossoms at 

 North Chatham June 6, 1902.
