antly and here, far out of reach, gorgeous butterflies and other 

 insects occurred in multitudes, and could only be induced to 

 descend by various lures. One species, Morpho heaiba, one of 

 the rarest of this genus, refused every enticement for a long 

 time until, quite by accident, it was discovered that it could be 

 attracted by the reflection of a small piece of looking glass 

 lying upon the ground. Butterflies of various species occa- 

 sionally congregated in such numbers in moist places that not 

 even space remained to insert a finger between them. At such 

 times one could sit down and select what he wished. Some of 

 the tributaries of the Amazon were infested with poisonous 

 weeds which impregnated the water to such an extent that 

 dangerous and even fatal effects resulted from wading in them. 

 During the dry season the river was lowered some thirty feet, 

 having broad sandy shores on either side. Many of the Lepi-

 that the final effect was that of a lace pattern. The narrator 

 exhibited a number of leaves thus bitten showing many inter-

 Chicago Academy of Sciences was held as usual at the John 

 Crerar Library on the 20th, eight members and one visitor 

 being present. The recorder read a letter from Mr. John Com- 

 stock enclosing a specimen of Terias mexicana which he had 

 taken October gtli at Williams Bay, Lake Geneva, Wisconsin. 

 This is unusually far north for this species, but the recorder 

 has since learned that Mr. Beer also captured two specimens 

 this year, one October 9th within the Chicago city limits and 

 one at Hessville, Indiana, south-east of Chicago, on October 

 1 6th. Mr. Higley announced the arrival of twenty Comstock 

 cases for the Academy collection. 



Mr. W. L. Tower gave a very interesting talk on his expe- 

 riences while collecting in Southern Mexico about sixty miles 

 south-east of Mount Orizaba. The locality was a fertile valley,
