MAY 5, 1898. 



Vice-President Dyar in the chair. There were present, also, 

 Messrs. Ashmead, Heidemann, Pratt, Banks, Busck, Marlatt, 

 and Dr. Yngve Sjostedt, Assistant to the Royal Entomological 

 Institute, Albano, Stockholm, Sweden. 



Under "Notes and Exhibition of Specimens," Mr. Pratt 

 exhibited a large series of specimens representing the different 

 stages of a pyralid moth ( Clydonopteron tecomce Riley) which 

 he had reared from the seed pods of the trumpet vine ( Tecoma 

 radicans} , its food plant. He stated that it was a rather rare in 

 sect. Discussion followed on the species by Messrs. Ashmead 

 and Dyar. 



Mr. Dyar exhibited the full-grown Iarva3 of the Xyela minor, 

 which he stated developed inside of the flowers of the pine, reach 

 ing full growth before the flowers fall. At this date most of the 

 larvae had already escaped from the flowers to enter the soil. 

 Larvae of this common saw-fly have never before been discovered. 

 In discussion, Mr. Ashmead commented on the larval character 

 istics, which he said supported and justified his classification in 

 which he had given the Xyelidas as a distinct family. The fact 

 of the abundance of the adults of these species about pine trees in 

 early spring was commented on by various persons, and the fact 

 that it had often been referred to was also recalled. In further 

 discussion of the structure of these larvae, Mr. Dyar pointed out 

 that in the two free feeding genera of this Xyelniaa rudimentary 

 abdominal feet are found, whereas in the other genus the abdom 

 inal feet are wanting. 



Mr. Banks exhibited a new species of Prosalpia, for which 

 he proposes the name pacifica. The species was collected in 

 California, and represented a genus new to this continent. The 

 peculiar' characteristics of the genus and its affinities were pointed
