The Ckib met for an hour at 5 o'clock p. m. in one of the rooms of 

 the Massachusetts Institute of Technology, a large and commodious build- 

 ing which was almost entirely given up to the work of the Association. 



The short time at the disposal of the Club- was occupied by the con- 

 tinuation of the Rev. H. C. McCook's lecture on the Honey-Ants of the 

 Garden of the Gods, Colorado, the first portion of which he delivered on 

 the previous afternoon. At its conclusion some remarks were made by 

 Prof. Cook and others on birds versus insects. 



Thursday was devoted by the Association to a visit to Cambridge. 

 Many of the Entomologists took the opportunity of visiting the rooms of 

 the Cambridge Entomological Club, where they were received by Mr. B. 

 P. Mann, the Secretary. 



FRIDAY AFTERNOON SESSION. 



The Club met in their room in the Institute of Technology at 4 

 o'clock p. m., Mr. A. R. Grote, Vice-president, in the chair. 



Dr. LeConte moved that, owing to a resolution passed at the general 

 session of the Association that morning, the Entomological Club do now 

 organize as a permanent sub-section of the Association ; he proceeded to 

 congratulate the Club on the honor thus conferred upon it. It was due 

 to the importance of the subject and the large attendance of Entomologists, 

 no less than to the number of interesting papers offered for their discus- 

 sion. The resolution was unanimously adopted and the Club at once 

 organized as a Sub-section with the officers elected on the first day of 

 meeting. 



Mr. E. Burgess, of Boston, gave an account of the structure of the 

 mouth organs of Butterflies, describing especially and illustrating with 

 diagrams on the blackboard, the proboscis, etc., of the Archippus. 

 Remarks were made upon the paper by Dr. Hagen and Messrs. Mann, 

 Cook and Riley. 



Dr. Hagen read a paper on the anatomy of Prodoxus decipiens, in 

 which he confirmed Mr. Riley's statements. 



Prof. Fernald read a paper on Phoxopteris angulifasciana, a small Tor- 

 trix feeding upon clover. 



Mr. O. S. Wescott, of Racine, Wis., gave by request an account of a 

 moth trap for collecting insects by light, which he had employed with 

 much success. Dr. Hoy and Mr. Mann also described insect traps that 

 they had found useful.
