Asparagus Beetles. 



Attention was called in my Notes of the last two seasons to the progress of the two species 

 if Asparagus beetles westward from the Niagara river. In 1899 they had reached St. Catharines ; 

 in 1900 nearly to Hamilton. Thi« year they were present in the Asparagus beds at the O. A. C. 

 fat 111 in considerable numbers. I have not heard of their appearance in places west of Guelph, 

 but undoubtedly they are Weshva'd, Ho! and are bound to join hands with their brothers in 

 Michigan. 



At the College the Twelve-spotted species {Crioceris 13-pn)ictatvs, fig. 19) was l)y far the

more abundant, and it is apparently leading the other species {G. asparagi, fig. 20) in its march 

 through Ontario. 



About St. Catharines the beetles did much damage. They appeared in such numbers on 

 the tender shoots and disfigured them so much ,that the shoots were unmarketable. They 

 seemed to gnaw the epidermis as the shoot was peeping above the ground, before it was ready 

 to cut for market. 



It is prjbable that when greater attention is given to the destruction of the beetles after 

 tlie spring cutting is over, fewer beetles will hibernate and give trouble in early spring.

 These insects were numerous the past seas:)n, and in some sections " alarm^was beginning 

 o be felt." Three species were common, viz , Upicauta Pennsylmnica, Epicanta cinerea.
