not yet been reported in the Connecticut valley. Tliis pest 

 passes its early stages iu the asparagus berry. 



On the 2d of June, IDOD, a Clialcid parasite was captured at 

 Amherst, laying its eggs in the eggs of the common asparagus 

 beetle (Crioceris asparagi L.). The parasite was quite abun- 

 dant, and was later discovered at Concord. It proved to be a 

 new species, and was described by Mr. J. C. Crawford of the 

 United States National Museum as Tetrastichus asparagi. This 

 insect has two and probably three broods a year, corresponding 

 to those of the asparagus beetle, and, to judge from its work 

 last summer, it promises to be quite effective in controlling its 

 host.
