REPORT OF THE STATE ENTOMOLOGIST I9OO IOI9 



in one garden. [Raphidodemas titea Cram.] was also taken at 

 this time. Ap. 26. Appletree tent-caterpillars [Clisiocampa 

 americana] made their appearance during a warm spell on Ap. 28. 

 It has been very cold since, the mercury dropping to 15 and 20 above 

 zero, and I have not seen any of them since then. May 10. I find on 

 a neighbor's trees many tent-caterpillars which have survived the recent 

 cold and rain. The town is full of birds, and they are doing good work 

 feeding on the forest tent-caterpillars [Clisiocampa disstria]. 

 May 18. The English sparrow has been eating the forest tent-caterpil- 

 lars, and last summer they attacked the cocoons and fed on the moths. 

 We have an unusual number of orioles, which I have seen feeding on the 

 caterpillars. I have also seen the yellow and several other warblers, the 

 yellow-billed cuckoo, the robin, the cedar waxwing and, I believe, the 

 house wren feeding on the caterpillars. The maples in front of the house 

 have been filled with warblers, all of which were very busy with the 

 trunks and branches, and yesterday I noted five varieties. May 26. We 

 have practically no forest tent-caterpillars in town. They hatched in 

 large numbers, but the cold evidently killed many, and the birds appear 

 to have cared for the remainder. They are said to be present in large 

 numbers in the country. The appletree bark louse [My til asp is 

 p omo rum] is abundant on appletrees, vines and shrubs. June 1. I 

 have seen but one forest tent-caterpillar since sending my last report. 

 The appletree tent-caterpillar is very abundant in the country. June 9. 

 Two fine maples are badly infested with borers [since proved to be 

 Prionoxystus robin iae]. June 16. I send you two pupal cases 

 [Prionoxystus robiniae] which were projecting from the trunk 

 of the tree. Much of the bark on this tree is loose, and the trunk is full 

 of burrows. June 20. Moths of [Prio noxy s tu s r o b i ni ae] were 

 taken on the infested maple today, the 2d. Pupal cases of this insect are 

 very abundant on the trees at the state hospital. Grasshoppers are pres- 

 ent in myriads, more than we have ever seen before. The spiny elm 

 caterpillar [Euvanessa antiopa] has done much damage to small 

 elms. July 2. There are a great many beautiful maples dying in tnis 

 vicinity, probably from borer attack, as mentioned above. The gouty 

 gall beetle, Agrilus ruficollis, is causing considerable trouble.

 appletrees and maples show signs of injury from the appletree tent-cater- 

 pillar [Clisiocampa americana] and from the forest tent-caterpillar
