The work of the last two years has been continued, and a large 

 number of observations have been added to previous records. 

 39 voluntary observers were appointed during the season, and 

 35 of them have rendered more or less detailed reports. The 

 summaries of these reports, representing as they do, the ento- 

 mologic conditions in 33 counties, are given below. 



Very naturally, owing to the great destructiveness of the for- 

 est tent-caterpillar, Clisiocampa disstria, and its close 

 ally, the appletree tent-caterpillar, Clisiocampa ameri- 

 c a n a, many of the reports dwell much on these two insects. 

 The Hessian fly, Cecidomyia destructor, has also 

 received considerable attention at the hands of the voluntary 

 observers. 



Summaries of reports from voluntary observers 

 The scientific names or other matter inserted in brackets indi- 

 cate determinations or information supplied by the entomolo- 

 gist. The other names are presumably correct, except where 

 questioned. The dates given after the records are those of the 

 reception of the reports, and they are usually from one to three 

 days later than the writing of the report. 



Albany county (E. T. Schoonmaker, Cedar Hill) — Forest tent- 

 caterpillars [Clisiocampa disstria] are hatching out 

 in large numbers, and the prospects are that they will be more 

 numerous than last year. Ap. 30. They are eating in the 

 center of the leaf buds and thus making their control exception- 

 ally difficult, though the cold weather of the past week has 

 caused them to remain comparatively inactive up to this date. 

 May 5. Elm leaf beetles [Galerucella luteola] have 

 appeared in limited numbers, though many still remain in build- 

 ings. The forest tent-caterpillars are quite abundant on maples, 

 and their ravages are now quite noticeable. Heavy rains have 

 checked their ravages to some extent, but conditions are not 

 favorable for their wholesale destruction. May 21. Striped 

 cucumber beetles [Diabrotica vittata], squash bugs
