Meetings.] 490 [1883. 



General Meeting, November 21, 1883. 



Prof. W. H. Niles in the chair. Twenty-four persons pres- 

 ent. 



Mr. E. Burgess showed a remarkable fabric spun by the larvae 

 of a Tineid moth. These larvae had woven a complete lining to 

 the top and sides of a bucket containing some corn on which 

 they fed. The lining was easily removed whole from the bucket, 

 and showed a wonderfully uniform texture, which, though ex- 

 tremely delicate, was found to be of considerable strength. Mr. 

 Henshaw identified the species as Euphestiainterpunctella Hiibn. 



General Meeting, December 5, 1883. 



The President, Mr. S. H. Scudder, in the chair. Twenty per- 

 sons present. 



The President announced the death of Dr. John L. LeConte, 

 for many years a Corresponding Member of the Society. 



Mr. George H. Barton read a paper on the lava fields and 

 streams of the Sandwich Islands, and presented one of two very 

 curious worm-like laval concretions, quite different from any 

 specimens before noticed. Mr. Barton showed other specimens 

 and photographs in illustration of the subject. 



Prof. Niles spoke of the causes of turns in lava streams, which 

 often occur independently of the formation of the ground over 

 which they flow, and which he believed were caused by sudden 

 congelation of the lava at some point, resulting in a dam which 

 would turn the course of the laval stream in another direction. 



A vote of thanks to Mr. Barton for his gift was unanimously 

 passed. 



Mr. S. H. Scudder alluded to the fossil genus Kamptecaris 

 from the Old Red Sandstone which Peach now shows is not a 

 Crustacean, as formerly supposed, but a Myriapod much older 

 than any previously described member of the group.
