section are in very bad condition owing to the work of the elm 

 leaf beetle. Striped encumber beetles continue very numerous, 

 and potato beetles have appeared in the past week in increasing 

 numbers. It looks as though the appletree tent caterpillars had 

 been destroyed by some climatic condition; possibly the severe 

 rains in May and June. Since we had 31 days of rain with hardly 

 a ray of sunshine, the webs are empty and there are no signs of 

 cocoons. Mosquitos are somewhat scarce. The work of the pear 

 midge (Diplosis pyrivora Riley) is very evident, and 

 cherry borers (probably the fruit tree bark beetles S c o 1 y t u s 

 rugulosus Ratz.) , have ruined some trees. — July IS 



Westchester county [Mrs Edwin H. Mairs, Irvington-on-Hudson] 

 — White marked tussock moth caterpillars (Notolophus 

 leucostigma Abb. & Sm.) are injuring the foliage of a fine 

 purple beech, which is also suffering severely from plant lice, 

 probably the woolly beech aphis (Phyllaphis fagi Linn.) . 

 Mapletrees have dropped many leaves, probably because of plant 

 lice injury. Very likely this is the work of Chaitophorus 

 aceris Thos. — June 29. A curious worm (Seirodonta 

 bilineata Pack.) was found feeding on foliage of purple beech. 

 Mosquitos are more abundant than ever. Elm leaf beetle larvae 

 (Galerucella luteola Mull:) are crawling along the 

 trunks of infested trees, the foliage of wmich is turning brown. 

 American, English, weeping and slippery elms are all attacked. 

 Maple and beech trees are still suffering from plant lice injury. 

 Some red bugs are present on the infested trees. — July 12 



Wyoming county [W. H. Roeper, Wyoming] — Appletree tent 

 caterpillars (Malacosoma americana Fabr.) were first 

 observed May 2. They are present in small numbers, and some 

 think this is due to the excessively cold weather. — May 9. Insects 

 of various kinds are much scarcer than usual. — May 18. Tent 

 caterpillars are not causing much injury though canker- 

 worms are working to some extent. The weather continues 

 very cold at night, and it is exceedingly dry. — May 25. Cod- 

 ling moth larvae (Oarpoc a p s a p omonella Schiff.) are 

 unusually abundant in this locality, and apple aphis (Aphis 

 m a 1 i Fabr.) is very numerous and rolling the leaves to a con-
