REPORT OF THE STATE ENTOMOLOGIST I9OO IOO3 



July 10. The green pea louse [PNectarophora pisi Kalt,] 

 has nearly destroyed some pieces. July 13. The pigeon Tremex, 

 Tremex tolumba, has been quite plentiful the past two weeks. 

 Many were found dead on the trunks of trees where they went to lay 

 their eggs. [The presence of this insect in numbers is good evidence that 

 the trees of Binghamton are in bad condition, most likely from the work 

 of the maple-borer, Plagionotus speciosus] Aug. 9. The yellow 

 necked appletree worm [Datana ministra] and the red-humped 

 appletree worm [Schizura concinna] were found injuring one tree. 

 A number of caterpillars of [Datana integerrima] were found on 

 a black walnut tree. Sep. i. 



Cayuga county (Joseph Foord & Sons, Auburn) — We can not see 

 that the recent cold weather has had any effect on the tent-caterpillars 

 [Clisiocampa americana], they appear as healthy as before the 

 freeze. May 14. 



Chemung county (M. H. Beckwith, Elmira) — I have just examined 

 several nests of tent-caterpillars [Clisiocampa americana], and 

 find them alive and active -vxhere the sun is shining on the nest. A few 

 cabbage butterflies [P i e r i s rapae] have appeared, and click beetles 

 are numerous. May 11. Larvae of the currant worm [Pteronus 

 ribesiij appeared on gooseberries May 14. May 19. Tent-caterpillars 

 are very numerous in this section. Potato beetles [Doryphoi;a 10- 

 lineata] have just made their appearance in quite large numbers. 

 Asparagus beetles [Crioceris asparagi] are very abundant. June 



I. Cut worms have been very numerous and have destroyed many 

 plants in tobacco fields. Potato beetles are few in numbers compared 

 with other seasons. June 2. The imported elm leaf beetle [? Galeruc ell a 

 1 u t e o 1 a] has been in this locality for several years, working mostly on 

 the elms near the Chemung river. Its depredations do not appear to be 

 as great this season as in former years, when at times it was so abundant 

 that the sidewalks and fences along the streets were literally covered with 

 the larvae. July 28. 



Clinton county (A. G. Meiklejohn, Plattsburg) — Young forest and 

 appletree tent-caterpillars [C lisiocampadis stria, C. americana] 

 were seen on the 21st here and there from Whitehall to Plattsburg. 

 A few cold days have caused them to disappear. Ap. 27. Young cater- 

 pillars ^ to J of an inch long were frozen stiff on the night of the loth, 

 but, when brought into a warm room, were soon as lively as ever. May 



II. Tent-caterpillars of both species are more than usually numerous at
