PROCEEDINGS OF MEETINGS. 



January 25. 1894. 



A regular stated meeting of the Entomological Section of the Academy 

 of Natural Sciences was held in the Hall, S. W. cor. Nineteenth and Race 

 Streets, this evening, Dr. G. H. Horn, Director, presiding. Members 

 present: Liebeck, Seiss, Calvert, Ridings and Skinner. Associates: Fox, 

 Boerner and Dr. Griffith. Mr. Calvert spoke of the work by Prof. Corn- 

 stock on evolution and taxonomy, and read passages therefrom. The 

 only previous work of any moment on this subject and relating specially to 

 wing structure was that of Redenbacher, written in 1886. Redenbacher's 

 views on the primitive structure of the wing were given by the speaker. 

 The views of Prof. Comstock on this subject were also given and explained 

 by the aid of blackboard sketches. Reference was made to the neuration 

 of dragonflies, and comparisons made with the wing structure of some of 

 the other orders. Dr. Horn considered the methods pointed out by Prof. 

 Comstock as the proper way to study. The question should always be 

 asked oneself when any new anatomical structure is found, why is it ? what 

 d(jes it mean ? Mr. Calvert exhibited a Coleopterous larvae collected last 

 September in a small stream in Delaware County, under and clinging to 

 stones. At first glance it appeared to be an Isopod crustacean, but Mr. 

 Liebeck had identified it as a Parnid larva, Dryops sp. Specimens were 

 also taken by Mr. Moore at West Spring Hill, Delaware County, Pa. Dr. 

 Horn stated that the larva had been actually described as a crustacean.
