February, '14] NEWELL: FILING CORRESPONDENCE 87 



.enemies of both moths, and during the past season arrangements 

 were made at the request of the Entomologist of the Dominion of 

 Canada so that parasitic material was collected in Massachusetts by 

 his assistants and shipped to New Brunswick and Nova Scotia, in 

 order to determine whether the species concerned would be useful 

 in contolling the brown-tail moth which has become established there. 

 Several shipments of parasitic material have also been sent to other 

 parts of the United States, where serious insects occur and where it 

 seemed probable that parasites would be useful in reducing the pests 

 concerned. 



Mr. Henry Skinner: I would like to ask whether anj^ stages of 

 the gipsy moth have been found where it has not become established. 



Mr. a. F. Burgess: I do not quite understand the question. 



Mr. Henry Skinner: Some time ago I had a full-grown gipsy 

 moth larva brought to me for identification from Philadelphia, and 

 this is the reason why I asked whether there have been other cases 

 where single caterpillars have been found in territory where the species 

 has not become established. 



Mr. a. F. Burgess: I am very sorry that you did not report 

 this case at the time so that we could have had the matter thoroughly 

 investigated. Not long ago specimens of brown-tail moth webs were 

 received from Philadelphia, but on investigation it was found that 

 they came originally from an infested orchard in Maine. 



It is possible for gipsy moth caterpillars to be shipped moderate 

 distances and survive, and possibly this is what happened in the case 

 which has been mentioned by Doctor Skinner. As a rule if one 

 caterpillar is found on the property more will be located if a thorough 

 investigation is made. I should be glad to get all information possible 

 concerning this matter so that we can have it thoroughly investigated. 



Mr. Henry Skinner: This occurred several years ago and there 

 is no way by which I can fix the date. 



President P. J. Parrott: We will now take up the next paper 

 by Mr. Wilmon Newell entitled, "A Simple and Economical Method 

 of Filing Entomological Correspondence." 



A SIMPLE AND ECONOMICAL METHOD OF FILING ENTO- 

 MOLOGICAL CORRESPONDENCE 



B}^ Wilmon Newell, College Station, Texas 



The handling of correspondence is a necessary part of the work of 

 the economic entomologist and by this means much valuable property 

 is saved from destruction by insects. At the same time, it must be 

 conceded that in offices or departments where the correspondence is
