them apart, or could you distinguish them if sent for determination? 

 No reply is expected. Not one of these important species should be 

 absent from any of our collections. By a little cooperative exchange 

 we might all have them, along with many others. 



The accumulation of the State fauna each must look after for his 

 own region, but the general economic collection can be made only 

 through some sort of cooperation. There are a large number of seri- 

 ous pests in rather restricted localities which should also be represented 

 in all economic collections so far as possible. In Colorado the bean 

 beetle {EpiJachna corrupta) is as bad on the wax beans as is the potato 

 beetle on potatoes; the fruit-tree leaf -roller {Cacoecia argyrospilci) I 

 have known to entirely defoliate whole orchards, and its close relative, 

 the box-elder leaf -roller {Ckiccecia semiferana)^ is equally destructive 

 to the foliage of the box-elder; the currant and gooseberry fruit fly 

 {Epochra canadensis) sometimes destroys three-quarters of the goose- 

 berry crop, and the plum gouger {Coccotoras prumcida) punctures 

 fully nine-tenths of our plums on the eastern slope, and still it would 

 not be surprising to learn that in many of the States not one of these 

 pests is represented in the station or agricultural-college collections. 

 This does not seem right. 



If the best way to build up our collection is by individual exchanges, 

 then let us follow that plan. If we can adopt some general method 

 and all work to it. let us do that. It seems to me this is a good prob- 

 lem for a committee to work out for us. In any case, let us all collect 

 large series of duplicates of those insects that are specially injurious 

 or beneficial in our different localities, and then endeavor by some 

 plan to better our economic collections, and those of other States, 

 through exchanges. I should be glad to hear of any who would like 

 to have Colorado's injurious and beneficial insects in their collections 

 and are willing to exchange species from other States for them. And 

 then, it is often important to have the same species from different 

 localities to note variations. 



Let us talk freely of our plans, and let us hear suggestions from 

 any and all in regard to methods and lines of investigation that seem 

 to you to be specially important. In this way we shall broaden our 

 horizon and get a larger view of the scope and importance of our work. 



The next object as stated in our constitution is ''to suggest when 

 possible certain lines of investigation upon subjects of general inter- 

 est." Such work would in large part be cooperative, but not entirely 

 so. Nothing, perhaps, would be of more general interest than infor- 

 mation and suggestions as to best methods of putting information 

 upon applied entomology into the hands of the connuon reader. To 

 what extent is it advisable to use the newspaper and the press bulletin? 

 Is it best to put out bulletins in two series, one for the farmer and one 

 for the station worker and specialists Shall we publish all data from
