A. ruficollis Fab. Common throughout the State in June. The larva 

 bores in stems of blackberry and raspberry, forming galls on some 

 varieties and becoming more or less injurious. Cutting out the galls 

 and burning the cuttings in winter destroys the brood. As the eggs 

 are all laid by July 1st, cutting out all shoots made at that time and 

 depending upon those starting after that date will secure exemption 

 for the year next following. 



A. lateralis Say. Eagle Rock (Bf) ; Staten Island (Lg) ; West Berlin VI, 

 25 (Brn); Buena Vista (Li); Brown's Mills VII, 4, Lacy VII. 14
