wiih the wind. The ends are neatly tucked into the somewhat ti<,du roll till 

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

 entire leaf is rolled, 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 octiviiaciilata Fabr. 



Reddish, black-ringed caterpillars about \]z 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 

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

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

 wings, which latter have a spread of \y, inches. 



Rose beetle 



Macrodactyhis siibspinosits 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 e(iuall\- 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 mos(]uito 

 netting. 



Calligraphus lunata I'abr. was found eating wild rose blossoms at 

 North Chatham June 6, 1902.
