Eleventh REroRT of the State Entomologist 181 



introduction shall prove to be an Upper Austral zone insect. Certain it 

 is, although perhaps only accidental, that by far the greater part of the 

 infested locality in northeastern Massachusetts is bounded by the Gannett 

 contour line of loo-feet elevation, which, there is reason to believe, will 

 hereafter be accepted as the boundary line in that part of New England 

 of the zone above named. 



Remedies. 

 In reply to the request in the inquiry for indication of a method for 

 destroying the insect, the following remedies for the asparagus beetle are 

 given in the First Report on the Insects of New York, '^^^Z^ viz., employ- 

 ing fowls for hunting the beetles, dusting freshly air-slacked lime over the 

 larvae upon the plants, cutting away the young seedlings, and the removal 

 of the seed-stems when the asparagus season is over. Of these, the lime 

 remedy is the most simple and, it is believed, the most effective.
