354 PROCEEDINGS OF THE ACADEMY OF [DeC, 



accessions for the year amount to 2,953 specimens, most of which have 

 been incorporated in the collection. 



A number of families have been rearranged: the Scarabsediae, 

 Rhipiphoridse, Stylopidse, Cleridse, Malachidse, Meloidae and Bu- 

 prestidse in the Coleoptera; the Scathophagidse, Sepsidse and Ephy- 

 dridse in the Diptera, and the large series of exotic Noctuidse among 

 the Lepidoptera. Some valuable material in the last order col- 

 lected by Dr. Skinner in the White Mountains of New Hampshire 

 was incorporated in the collection. In the order Hemiptera the 

 family Cicadidse has been rearranged in accordance with identifica- 

 tions made by Mr. Wm. T. Davis, and in the Hymenoptera the 

 H. L. Viereck types of Andrena have been placed in the type series. 



In the Orthoptera besides the mounting and rearrangement of 

 material, studies have been made of an extensive series of Brazilian 

 material and three papers prepared and published upon it. A study 

 has also been made of our African material as well as of several Afri- 

 can collections loaned for identification, of which the Academy will 

 receive a series of duplicates. A paper was also published in the 

 Proceedings on the North American Eumastseinse, while corre- 

 spondence by Mr. Rehn has resulted in the receipt of valuable 

 material in return for determination. 



Several visiting entomologists, especiallly Dr. E. C. Van Dyke, have 

 made use of the collections and material has been loaned to J. R. 

 Malloch, J. S. Hine and R. W. Dawson. 



Plants. 



Mr. Stewardson Brown, who has had charge of the herbarium, 

 reports that during the year the herbarium of the late Charles S. 

 Williamson, presented by his sister Miss Mary Williamson, has been 

 distributed throughout the herbarium so that the specimens are now 

 readily accessible with the other material. The J. J. Carter her- 

 barium, the gift of Mr. H. S. Gatchell, has been in a great part mounted 

 ready for stamping and distribution. Numerous other collections 

 received from various sources have been mounted by Miss Ada 

 Allen, who has been continued as an aid in this work. 



The local collection has received considerable attention from 

 Mr. S. S. Van Pelt, who has mounted many specimens that have been 

 received. Mr. Bayard Long has also given the collection considerable 

 critical study. 



Minerals and Rocks. 



The Curators are indebted to Mr. F. J. Keelej'", Curator of the 

 William S. Vaux collection, and to Mr. Samuel G. Gordon, a student
