KEPORT OF THE ENTOMOLOGICAL SECTION. 



The usual meetings liave been held and entomological communi- 

 cations of interest and scientific value have been made by members 

 and associates. The attendance has been good, the average being 

 fourteen persons. 



Seven associates have been elected during the year. 



The Entomological News and Froeeedings of the Entomological 

 Section of The Academy of Natural Sciences of Philadelphia has 

 been continued with increased success. During the year the 

 twelfth volume has been completed with three hundred and 

 twenty-eight pages and thirteen plates. 



The Section has had a very eventful year, due to the large and 

 valuable additions of specimens to the collections of the depart- 

 ment. Two representative collections of Hymenoptera have been 

 presented: the Cresson Collection and the collection of Gallflies 

 made by INIr. Homer F. Bassett, of Waterbury, Conn. The 

 former collection contains 2,867 types and 3,511 species and the 

 number of specimens is estimated at 87,775. The Bassett Collec- 

 tion contains 315 boxes, estimated to contain 6,300 specimens and 

 over 300 types. The collection of Orthoptera made and presented 

 to the Section by Mr. J. A. G. Rehu numbers 1,653 specimens. 

 In addition the Academy has purchased 3,500 specimens. These 

 collections, in conjunction with the material already in the posses- 

 sion of the Section, form the best museum collection of these 

 insects in America. The Conservator has added over a thousand 

 specimens collected in San Miguel county, N. M., during the 

 summer. About forty species of these are new to science, and 

 many are new to the collection. The specimens added to the cab- 

 inets during the year will number nearly 104,000.
