fly during the past season. Owing to the drought the fly had not 

 emerged until the time that wheat was well up. Wheat should 

 not be sown until after rain has broken the drought. 



Mr. Daecke exhibited specimens from Manumuskin, N. J., 

 including .\uthocliaris gcnutici, April 2_|.th. Also a Catocala 

 rclicta from Philadelphia "Neck." 



In connection with these specimens Prof. Smith remarked 

 that among them was one of the rare . l^rot/s I'io/aris. 



The oviposition of Cicada hieroglyphica was referred to by 

 Prof. vSmith. He had found a pupal skin of this species in a 

 decayed cavity inside of a pine log. The pupae usually cling 

 to the bark of trees which they may ascend. 



Mr. H. Wenzel said he had found Cicada canicnlaris com- 

 monly in the latter part of August at Anglesea, N. J. 



Dr. H. Skinner referred to a recent paper on the genus 

 Argynnis, and a criticism by Mr. Lyman thereon. He spoke 

 of the lack of data to specimens on which earlier work on this 

 genus was based, and considered this to be the reason for the 

 errors which had been made. He believed that a study of 

 geographical distribution would settle many points in regard 

 to synonymy in Ar^'vimis, as many so-called species are, no 

 doubt, only geographical variations. 



Mr. Reinick exhibited some tri-color process plates of insects 

 issued by a Boston concern, and referred to errors in names and 

 coloration. As these were issued for educational purposes he 

 thought attention should be called to the matter. 



Mr. Harbeck referred to the abundance of Passaliis corn at its 

 in logs in Fairmount Park, Philadelphia. 



The occurrence of this species was further discussed by H. 

 Wen/el, Smith, Johnson, Harbeck. 



Mr. H. YVen/.el reported that he had recently taken several 

 species of Pselaphidse in the lowlands of New Jersey, which 

 had been described from mountain altitude- 

 Prof. Smith did not believe elevation counts for much in the 

 distribution of insects of this character. 



The probable change of temperature in dead and live trees 

 as effected by external inllucnco was discussed by 

 Daecke, Smith, \Yen/el, Laurent and others.
