The curator. Dr. Lutz, reported that Mr. Sherman had prepared a list of 

 the aqviatic Coleoptera in the local collection and that he. Dr. Lutz, had pre-

 these synoptic tables. 



Mr. Schaeffer, for the Publication Committee, reported that all manuscript 

 for the fourth number of the Journal had been sent to the printer with the

 to the late Otto Seifert, particularly some of the specimens with which Dr. 

 Seifert conducted experiments with temperature effects on the early stages.

 bers of the Society and present the collection to the Museum in appreciation of 

 what it had done for the Society.
