is certainly an effective scale destroyer on smooth-barked trees, 

 and no better treatment is known for the peach orchard than to 

 spray it in the spring with the lime-sulphur wash, which is an 

 excellent fungicide and a good preventive of leaf-curl. 



INSECT NOTES. 



Snow-White Linden Moth Abundant. On July 8th the Associ- 

 ated Press and several New Haven newspapers telephoned to the 

 entomologist's office regarding the reported occurrence of the 

 brown-tail moth in Woodstock, where some newspaper corre- 

 spondent had reported it as being abundant and swarming around 

 the street lights. Through telephone and written communication 

 with several reliable men in that part of the state, including Mr. 

 L. H. Healey, Master of the State Grange, this report could not 

 be verified and specimens could not be obtained. 



A few days later the New York papers told about a pure white 

 moth that swarmed about the electric lights in New York and 

 Brooklyn. On July 19th a similar swarm of white moths appeared 

 in New Haven, and the description was a feature of the news- 

 papers the following day. These moths were present for about 

 two days, then disappeared, but were very abundant while they 

 lasted, and may be the same species as that reported from Wood- 

 stock. This moth is called the snow-white linden moth (Ennomos 

 subsignarius Hiibn.), and in some books is mentioned under the 

 name of elm span worm. It feeds upon a variety of forest and 

 shade trees, and is reported as causing much damage to beech 

 trees in New York State in 1907,* though linden, ehn, maple, 

 chestnut and horse chestnut are often damaged. 



This moth is pure white, has a wing expanse of about one 

 and one-half inches and is shown on Plate LIX a. It is frail, 

 with angulated wings, and belongs to the moth family Geo- 

 metridas, the larvae of which are measuring worms or loopers. 

 There is one generation each year, and both sexes have wings. 

 Spraying the foliage with arsenical poison is about the only 

 remedy.
