ated unfavorably, though good collecting was found along the moist bank of 

 the river, where apparently insects had congregated. The same result seemed 

 to be indicated by the collecting in the dry bed of a stream, where the few 

 rockbound pools and muddy spots afforded good collecting. Sifting, turning 

 boards, etc., proved unprofitable here and elsewhere, presumably on account 

 of the abundance of insectivorous centipedes, lizards, etc. 



Leaving the mountainous interior after ten days' collecting there, the 

 party spent a few days at Ponce, finding good collecting at a little place called 

 Tallyboa, reached easily by train, where enormous cactus and century plants 

 abounded. Mr. Barber pointed out that on the southern side of the island, 

 near Ponce, the coastal plain is usually sandy with only an occasional marsh, 

 qvtite different in this respect to the abundant mangrove swamps of the 

 northern shore. 



There is much cultivated land, especially sugar cane, with little other 

 vegetation and few waste places, while the open fields and denuded hills are 

 equally unfavorable to insects in their wind-swept dryness. 



The next station, reached by railroad, was Mayaguez, where the U. S. 

 Experiment Station was placed at the disposal of the travelers and the ento- 

 mologist R. H. van Zwaluenberg pointed out good collecting places. 



The results were excellent although the most ambitious excursions, 

 climbing back into the mountains, was rather unproductive, from lack of 

 time, for collecting purposes. 



Following around the western and northern coast back to San Juan, the 

 only stop was made at Arecibo, where again the dry season prevented the best 

 results. 



In closing, Mr. Barber spoke of the kindness of Major Dutcher and of the 

 staff at the Porto Rican Experimental Station at Rio Piedras, near San Juan ; 

 and promised to review the scientific results of the month's work at a future 

 meeting. 



At the close of his remarks, Mr Watson exhibited a large number of 

 the butterflies, of which large series had been obtained and spread. 



The paper was discussed by Mr. Davis, who commented on the uniformly 

 smaller size of some species as compared with American examples, by Dr. 

 Osburn and Messrs. Angell and Engelhardt. In reply to their questions, Mr. 

 Barber said collecting at lights was not very satisfactory in the towns on ac- 

 count of interference by people. 



Mr. Leng and Mr. Davis jointly described a recent \isit to Ithaca, speak- 

 ing of the methods used in the collections and of the large staff of ento- 

 mologists there occupied in teaching and research work. The numerous 

 ravines and waterfalls and the more northern character of the locality were 

 shown by photographs, and Mr. Davis commented on the uniformity of the 

 rocks as compared with the varied glacier-born rocks of Staten Island. The 

 block system used in the collections was explained, also the tents devised by 

 Professor Needham for environmental study. Mention was also made of the 

 three places that had been selected for field work in the western part of
