74 Report of the President 



An extensive exhibit has been installed in the Hall of In- 

 sects, which consists of representative specimens illustrating 

 the insect fauna of the northeastern United 



Insects and States. Pages from the "Field Book of In- 

 Spiders 



sects," by Dr. Lutz, are used as labels for this 



exhibit, and by this unique method the value to the student 

 is greatly increased. Cooperation with specialists outside of 

 the Museum has been continued with mutual advantage, es- 

 pecially in the case of the New York Entomological Society, 

 which has charge of the Collection of Local Insects. The col- 

 lections at large are in better condition than ever before, and 

 their growth during the last year has been greater than the 

 average of 50,000 per annum for the last decade. The staff 

 have been unusually successful in caring for the current acces- 

 sions, and in the prosecution of their researches. Dr. Bequaert 

 has continued his services as a temporary assistant. Mr. A. 

 C. Kinsey, of the Bussey Institution, has devoted considerable 

 time to the arrangement of the cynipid wasps and the charac- 

 teristic galls made by them, especially on oaks and roses ; his 

 important papers concerning these insects and the curious 

 alternation of generations in their life history will be pub- 

 lished in the Bulletin. Mr. Carl Heinrich, of the United 

 States Department of Agriculture, spent three weeks at the 

 Museum arranging the Kearfott Collection of Microlepidop- 

 tera which the Museum acquired several years ago, partly by 

 purchase and partly by gift. In general, these are the moths 

 whose larvae roll leaves or live inside the substance of leaves 

 or stems. This collection contains a great many type speci- 

 mens, but, aside from that feature, its importance in facilitat- 

 ing the work of identifying subsequently received material is 

 its completeness, as indicated by the fact that, in the family 

 Olethreutidse, it contains 485 of the 533 species listed from the 

 United States. The collection was received in a somewhat 

 confused condition, but Mr. Heinrich's work makes it avail- 

 able for use.
