recorded biological and ecological facts, thereby adding, fraction- 

 ally to be sure, but none the less positively, to our meager store 

 of knowledge. These lists frequently serve as a sort of assay- 

 piece or apprenticeship to catalogue writing, since no carefully 

 prepared list is a mere slap-dash, hodge-podge concatenation of 

 names, but rather is the result of a certain amount of careful 

 research in the matter of classification, nomenclature and distri- 

 bution. 



The fact that the faunal list as such has had eminent advo- 

 cates — among hemipterists such men as Osborne, Van Duzee, 

 Uhler, and other lesser lights — is evidence not only of its useful- 

 ness, but of its importance as well. 



MANUAL OF THE HEMIPTERA OF EASTERN NORTH 

 AMERICA IN PREPARATION. 



The special studies of the undersigned have now reached the 

 point where it seems possible to produce an extensive and approx- 

 imately complete work on the Hemiptera (Heteroptera) of the 

 eastern portion of the continent, and rapid progress is now being 

 made on it. It is intended that the work v/ill not only provide 

 the means for the identification of the species, but also include full 

 treatment of the biology and literature of the group. The au- 

 thors will be glad to receive collections for study and identifi- 

 cation.
