CRIOCERIS Geoff. 



C. asparagi Linn. Throughout the State wherever asparagus grows, from 

 early spring to late fall, in some stage; hibernates as an adult. An 

 imported species, often very injurious. On young plants brush the 

 slugs from the shoots to the ground on the middle of a hot sunny day. 

 On larger plants apply dry hydrate of lime with a powder gun very 

 early when the plants and slugs are a little moist. Destroy all volun- 

 teer asparagus; in bearing fields let trap shoots grow until covered 

 with eggs, then cut and destroy them. 



C. 12-punctata Linn. Also an introduced asparagus feeder, more recently 

 arrived, not so common and not so widely distributed in the northern 

 half of the State as the preceding.
