[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, 
Rhipiphoridae, Stylopidae, Cleridae, Malachidae, Meloidae and Bu- 
prestidae in the Coleoptera; the Scathophagidae, Sepsidae and Ephy- 
dridae in the Diptera, and the large series of exotic Noctuidae 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 Cicadidae has been rearranged in accordance with identifica¬ 
tions made by Mr. Win. T. Davis, and in the Hvmenoptera 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 Eumastseinae, 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.
