beetles (Crioceris asparagi Linn.) are plenty. There 

 are not many potato beetles as yet. Cigar case-bearers (Coleo- 

 phora fietcberella Fern.) are very numerous in some 

 orchards. Something has happened to tent caterpillars, as they 

 are extremely scarce ; so evident is this that it is a source of com- 

 mon remark. There are no evidences of injury by cankerworm. — 

 May 25. The cabbage root maggot (Phorbia brassicae 

 Bouche') is unusually numerous and very destructive to early cab- 

 bages. The four-lined leaf bug (Poecilocapsus lineatus 

 Fabr.) is quite abundant and, as usual, is indifferent as to what 

 kind of plant it attacks, occurring with great impartiality on 

 burdock, peppermint, sage, currant etc. Cankerworms are very 

 scarce in this immediate vicinity, but are reported as having done 

 considerable damage in orchards between here and Rochester. 

 In a trip to Niagara Falls I observed several orchards between 

 LaSalle and that place, which were brown from the work of this 

 pest. — June 3. There is practically no Hessian fly (Cecido- 

 m y i a destructor Say) as after inquiry at a grange meet- 

 ing, onlj- one farmer reported any, and that was in a field of late 

 sown no. 6 white wheat. A similar inquiry regarding canker- 

 worms and tent caterpillars resulted in statements that very few 

 or none had been seen. There is some complaint of plant lice on 

 plum and cherry trees. — June 15. The black or cucumber flea 

 beetle (Crepidodera c u c u m e r i s Harr.) is much com- 

 plained of and has not only perforated potato leaves but is said 

 to be at work on corn and beans as well as tomatoes. The striped 

 cucumber beetle (Diabrotica vittata Fabr.) is very 

 numerous on squash, melon and cucumber vines, nearly destroy- 

 ing them in some gardens. Following our severe drouth Ave have 

 had three weeks of drizzling rain, and plant lice are very bad on 

 fruit and other trees. We have never seen them on so many varie- 

 ties of trees till this year. The young growth of quinces for 6 

 or 8 inches on each shoot is a mass of lice, and the leaves are black- 

 ened and rolled up. This plant louse outbreak has been exceed- 

 ingly severe and injurious to a great many plants. There is a 

 very general complaint among cabbage growers about the root
