Professor Smith made the speech of the evening on " Our 

 Twentieth Birthday," in which he gave the history of the 

 Society in every particular, referring to Messrs. Simon Seib, 

 the Society's first President and Julius Bunsow, its first Secre- 

 tary, both of them members to this day ; he also spoke of the 

 Society's ups and downs and the good standing of it at the 

 present time with thirty and some odd members, most of them 

 active, enthusiastic collectors, and new ones added at nearly 

 every meeting. 



Mr. Engelhard gave a very interesting account of his and

 maculatus, C. diastatops and Libelhda quadrhnaculata, from 

 Poyntelle, Wayne County, Penna., June, 1904, being the first 

 records of those species in Eastern Pennsylvania. The two 

 cordulegasters were taken along the same brook, C. dias- 

 tatops in the open meadow, C. maculatus in the woods ; a cor- 

 relation between the different amounts of light in the two 

 localities and the size of the eyes (larger in niaculatiis) was 

 suggested. The 9 C. diastatops was observed to make the 

 same motions of oviposition as seen in the Libellulinse and 

 Gomphinae, by striking the water of the brook repeatedly with
