INSECTS AFFECTING PARK AND WOODLAND TREES 



their annoying operations in dwellings in Albany and vicinity. Dr A. S. 



Packard has recorded this species as injuring a wounded elm tree at Salem 

 Mass., and Dr Hagen cites an instance where 

 it attacked living maple trees. He states that 

 three trees more than 60 feet high and 2 feet 

 in diameter and apparently in good condition, 

 except for a splitting of the bark in some places, 

 were infested. On removing portions of the 

 bark, living white ants were found and proved to 

 belong to this species. Observations revealed 

 mes fUvipes: ,i=dorsai thc prcsencc of Small open gangways, covered 



ewly hatched larva; 6=vcn- 

 tral aspect of same; f=egg, all enlarged.

outside by the split bark, 

 which ran along the tree 

 to a hight of 30 feet or 

 more. There were no 

 old rotten stumps near 

 by, except on some of the 

 adjacent estates. The 

 infested trees were 

 remarkable for their 

 abnormally small leaves 

 and an examination 

 showed that the bark in 

 the vicinity of the gang- 

 way had been extensively 

 bored by these miners.

 of this insect and the different forms the species assumes are so well known 

 that detailed descriptions of them in this connection seem hardly necessary.
