have been examined, also a specimen from Malaga, New Jer- 

 sey, taken by Mr. E. Daecke. It appeared as Nehalennia 

 integricollis, a nomen nudum, in the New Jersey List of 1910. 

 The female of the new species is more nearly related to the 

 European speciosa, in the same genus than to any of the Amer- 

 ican species. The differences between the species were pointed 

 out and illustrated by sketches. 



A letter was read from Mr. Nathan Banks requesting the 

 Section to appoint two persons to represent it on the Nomen- 

 clature Committee of the International Entomological Con- 

 gress. Mr. J. A. G. Rehn and Mr. E. T. Cresson, Jr., were 

 elected to act in this capacity. 



Mr. John Enburg was elected an Associate of the Section. 



Meeting of September 25th, 1913. Mr. H. W. Wenzel, 

 Vice-Director, in the chair; twelve persons present. Mr. J.

 care necessary to determine these points accurately. He men-

 Diptera and compared the work of himself and another en- 

 tomologist working on the same group and said their work 

 was quite dissimilar. He mentioned the numerous local lists 

 published in England and the many local societies there. 



Dr. Calvert referred to Hagen's figure in the Zoologischer 

 Anzeiger for 1889 of an Odonate wing (Epiaeschna heros] 

 split into its two laminae and exhibited a similar preparation 

 of a wing of Libellula luctuosa Burm. mounted as a lantern 

 slide. The wing of a teneral specimen was cut off close to 

 the body and the two laminae separated at the base of the 

 large veins enough to admit of the entrance of the nozzle 

 of a pipette. The wing was then immersed in water and 

 water forced in between the laminae by the pipette until the 

 laminae were completely separated and the wing resembled 

 a sack or bag. The laminae were then cut apart along their
