learn anything of its life history, as a number placed in a breeding 

 cage failed to breed in confinement. 



Monoptilota nuhilella. On July 16 a number of lima bean plants, 

 upon the stems of which were numerous galls, were sent to the depart- 

 ment by Mr. Oscar L. Moore of Salisbury. They varied in length 

 from % inch to II/2 inches. An opening had been made by the larvs 

 in one end. Upon cutting into one of these galls, a beautiful bluish 

 green larva was found to be responsible for their formation and the 

 subsequent injury to the plants. The larva is a striking one in ap- 

 pearance, because of its uncommon metallic blue reflections. Several 

 of the adults emerged from the galls and were identified as Monoptilota 

 nubilella. A detailed account of this insect by Doctor Chittenden of 

 the Bureau of Entomology may be found in Bulletin 23, new series, 

 U. S. Department of Agriculture. 



This pest was first found in the state in 1899 and has no doubt been 

 responsible for more or less injury to lima bean plants since that time. 

 No serious complaints of its injury came to the office, but should it be- 

 come plentiful, it would no doubt be a hard pest to combat. The only 

 means of control suggesting itself would be the removal of the galls 

 from infested plants. 



Thyridopteryx ephemeraeformis. This species of bag worm was re- 

 sponsible for a large amount of injury to fruit and shade trees the 

 past season. Numerous inquiries as to its name and habits were re- 

 ceived from widely separated localities in the state, showing that its 

 occurrence was general. In many different places the writer saw 

 evergreen trees, mostly arbor vitae in hedges, killed by it. Its attack 

 was by no means confined to evergreens, however, for it was found on 

 locust, blackberry, rose, maple, apple, plum and cherry. Young fruit 

 trees seemed especially subject to its attack and trees in several young 

 orchards visited were badly stripped. 



Other pests of the season which were responsible for more or less 

 damage but deserve no more than passing mention were : Army 

 worm (Heliophila unipuncta) , old-fashioned potato beetle (Epicauta 

 vittata), bean leaf beetle (Ccratoma trifurcata), striped cucumber 

 beetle (Diabrotica vittata), stalk borer (Hydroecia nitela), red humped 

 apple worm (Schizura concinna), yellow-necked caterpillar (Datana 

 ministra), and corn bill bugs (SphenopJiorus sp.). 



ENTOMOLOGICAL NOTES FOR 1907 



By E. P. Felt, Albany, N. Y. 

 The climatic conditions of 1907 departed widely from those of nor- 

 mal years, and as a result the development of animal and plant life
