Entomological Section. 



The Recorder reports that the meetings of the Section, at which 

 Interesting communications were made, have been well attended 

 during the year. One member and one associate were elected. 

 The Entomological News, the journal published by the Section, has 

 been continued, 334 pages and 15 plates having been issued. The 

 collections have been useful to our own students, and a number of 

 investigators from other scientitic institutions have visited the 

 Academy to study them. Over 37,000 specimens have been added 

 during the year, 25,000 having been collected by an expedition 

 sent out by the Academy. Many species new to science have been 

 described by the members of the Section and a few have been sent 

 to specialists elsewhere for study and description. The collections 

 are in a good state of preservation and improved boxes and cabinets 

 have been added. Additional floor space has been granted and 

 enclosed by the Academy to provide for the growth of the Section.

 have been received, the greater number being donations. 



The most important of these is a collection of Western American 

 plants, consisting of 1,925 species and numbering considerably over 

 2,000 mounted sheets, representing most of the characteristic genera 

 and a large number of the species of the Rocky Mountain region, 

 presented by Mr. Benjamin H. Smith, the collection having been 

 made by him some years ago while living in that district. It com- 

 prises, besides plants of his own collecting, those of Pringle,
