distinctive nomenclature in cases in which peculiar features 

 were present, even if little value had been assigned to them 

 elsewhere. 



November 7, igoi. — Twenty-nine persons present. Prof. 

 John B. Smith presiding. Mr. John Kalbert was elected a 

 member. 



Prof. Smith spoke upon the structure, life history and de- 

 struction of certain species of mosquitoes. He made detailed 

 explanation of their methods, the result of their attack and 

 their position as purveyors of various febrile and malarial 

 diseases. His remarks were illustrated by lantern views and 

 embodied many of his original investigations and observations. 



December ^^ igoi. — Twenty-five persons present. Prof . John 

 B. Smith presiding. The death of Dr. Herman Strecker was 

 announced, and Messrs. Graef, Love and Weeks were appointed 

 a committee to prepare suitable resolutions. 



Dr. Love exhibited a box of Ichneumonidae, and suggested 

 the propriety of noting and preserving carefully all parasites 

 emerging from pupae, for the purpose of increasing our knowl- 

 edge of this family. 



Dr. Seifert exhibited some 750 bred specimens of Arctia nais 

 supposed to be var. vittata, and related his experience in breed- 

 ing from a gravid female which he took in Florida in March, 

 and his inability to mate its progeny with vittata in this local- 

 ity. He had also made experiments in rearing the larvae of 

 nais upon various food plants, and had subjected the pupae of 

 different broods to extremes of heat and cold. 



Discussion as to effects of heat and cold and aestivation, by 

 Prof. Smith, Messrs. Franck, Graef, Meeske and Weeks. Mr. 

 Weeks instanced an Acronycta chrysalid found in March, 1901, 

 the larva of which undoubtedly pupated in the fall of 1900, 

 and which had so far failed to emerge, though still alive. (The 

 moth proved to be A. americana'zw^ appeared in May, 1902). 



Mr. Franck exhibited a second specimen of P. philenor, var. 

 wasmuthi, which had been taken in Flatbush the previous 

 summer, and stated that a .S. cynthia $ had been found in 

 copulo with a P. cecropia.
