 journment o( Section F on Thursday. 



Prof. Comstock appointed ^Messrs. Smith, Cnok and Hulst a 

 committee to obtain papers and prepare programmes lor liie meetings of 

 the Club. 



Mr. Hassett asked whether an}- one could tell linn positively how 

 many broods of the Curiant Worm there are annually. 



Prof. Cook said in Michigan ihcre are iv.ti; Dr. Morris said two 

 near Baltimore ; Prof. Riley said probably three in the South — this is not 

 certain, for the insect is rareh injuiious diere, and attracis less attention, 

 he believes that from information iie has reccivetl, but that norlhwarcllv 

 where it is injurious, there are t\\o broods only. Prof Coinstock said 

 the\' have two broods. 



Mr. Ba.ssett said that until recently he had believed llie same, but 

 last Summer a friend brought him every few days eggs and larvae in all 

 stages throughout the season — whereat he was very much surprised and 

 thought it indicated more than two generations. 



Prof Riley replied that this was true — they did appear in that way 

 but that was merely a difference in the time required for development, 

 some running through their transfoimations much more rapidly than 

 others. There are however only two well marked broods which overlap 

 and leave probably none (-)r only a short interval between tliem. 



Prof. Cook confirmcil this statement. They have in Laboratory ex- 

 periments carried over the pupa> of the spring brood until the following 

 Summer, and in the same way the Cotidling moth has lieen carried over. 



Prof Cook asked for information regarding the whereabouts of the 

 early broods of the Hessian fly- — stating that he failed to account for the 

 large numbers there appeared, by what he found in Volunteer wheat, and 

 that he hatl f^nind them nowhere else. 



Prof. Riley said the subject is too large a one for discussion in the 

 few minutes l)efore adjournment and proposed an adjournment of the 

 matter, to which Prof Cook agreed. 



Mr. Angell on behalf of Mr. E. L. Graef invited the members to an 

 informal recepdon at his house in Brooklyn. 



The meeting then adjourned to Thursday, after the adjournment of 

 the BioloKfical Section.
