dent, Wm. H. Ashmead ; Vice-Presidents, Theodore Gill and 

 C. L. Marlatt; Recording Secretary, L.O.Howard; Corre 

 sponding Secretary, F. H. Chittenden ; Treasurer, E. A. Schwarz ; 

 additional members of the Executive Committee, George Marx, 

 B. E. Fernow, and C. V. Riley. 



The delivery of the annual address of the outgoing President, 

 Prof. C. V. Riley, was postponed for one month. 



The first paper of the evening was by Mr. C. L. Marlatt, en 

 titled " Revision of the genus Pontania, Costa, with Descriptions 

 of New Species." The relationship of this genus, which is a 

 subdivision of the old genus Nematus, was explained, and its 

 characters pointed out. A list of seventeen species which will 

 belong to it in the North American fauna was given, and the 

 prominent characters which may be used in the classification of 

 these species and in their differentiation were explained. The 

 genus includes small species of the old genus Nematus of gall- 

 making habits, so far as known, and include the well-known 

 species salicis-pomum and pisum making the common leaf-galls 

 of the willow. Seven of the species are new. In answer to a 

 question by Prof. Riley, Mr. Marlatt pointed out the salient 

 characters separating the genus Pontania from Euura, the species 

 of the latter genus, in gall-making habit, being closely allied to 

 the former. 



Mr. Chittenden presented, by title, the following paper : 



ON THE HABITS OF SOME LONGICORNS. 

 By F. H. CHITTENDEN. 



The notes which follow are based on the writer's personal ex 

 perience, and the dates of rearings given are, for the most part, 

 as in nature. In very many instances the material from which 

 the species herein mentioned were reared was gathered but a few 

 days before the transformation of the insects and kept in an un- 

 heated room. 



In referring to published records the observer's name is men 

 tioned for authority, as most of these records are to be found in 

 Dr. A. S. Packard's report on forest insects (Fifth Report U. S. 

 Ent. Comm.) and that of Mr. A. D. Hopkins (Bull. 33, W. 

 Va. Agl. Expt. St.). Other records are given in articles by 

 Dr. C. V. Riley and Dr. J. L. LeConte in the third volume of 

 the American Entomologist.
