508 SEVENTH REPORT OF THE FOREST, FISH AND GAME COMMISSION. 



spittle masses were observed in the early part of the summer, and the a.dult insects 

 were captured from the latter part of June through September. 



Aphrophora saratogcnsis Fitch was the most abundant form and was captured in 

 sinall numbers from the last of June till after the middle of September. It may be 

 recognized by its uniform brown color, variegated with very light brown or yellow. 

 It is a slender species about y% of an inch in length. 



Aphrophora parallcla Say was taken in smaller numbers during July. The adult 

 is nearly i^ of an inch in length, dark brown mottled with black, and may be easily 

 recognized by the whitish spot near the center of each wing cover. (Plate 12, 

 figure 22.) 



Aphrophora quadrangularis Say is a smaller species than either of the two pre- 

 ceding and measures about ^ of an inch in length. It is a rather pretty, oblique- 

 banded form w'hich was met with in small numbers on hard pine during August and 

 September. 



INSECTS AFFECTING THE FOLIAGE. The foliage of the pine is attractive to a 

 considerable number of insects and a few of the more important are noticed in this 

 connection. 



LE CONTE'S SAW-FLY. 



Lophyriis Iccoiitci Fitch. 



Dirty yellowisli, black spotted caterpillars may be met with in clusters on the 

 upper branches of pines in July and in Septem.ber and October. These insects feed 

 upon the old leaves and therefore cause less injury than those that attack the 

 recently developed ones. They live in companies and frequently strip one or more 

 branches. Dr. Fitch states that these worms, when nearly mature, are so large that 

 two often unite, standing face to face and holding together the five leaves which form 

 a bundle, commence at the tip and gradually eat it down to the base. The larvae 

 and their work are represented on plate 13, figure 8. There are several other species 

 which possess similar habits. 



LIGHT LOVING GRAPEVINE BEETLE. 



Anoutala Incicola Fabr. 



This short, stout, little beetle, measuring from '^ to nearly ^ of an inch in 

 length, was very abundant the latter part of June and throughout July, 1901, on 

 hard pines at Karner. It may be easily recognized by the illustration at plate 12, 

 figures 12, 13, 14, and is universally known as the grapevine beetle. It undoubtedly
