RECORD OF PROCEEDINGS. 23 



growing in Duck Creek. In and about Chippiannock Cemetery, 

 south of Rock Island, lie found great numbers of ferns, among 

 them several rare species. In company with J. D. Putnam he 

 had made a trip to Walcott on June 10th, and collected several 

 new plants, but was not prepared to report to-night. 



Mr. J. D. Putnam reported a considerable number of insects 

 collected during the month, among them several not before re- 

 corded from this locality. A very pretty myriapod with re- 

 markably long legs and appendages i^Cermatia forceps^'afR.') has 

 been several times brought in, but it does not appear to be com- 

 mon. The large, uncouth insect, known as the helligramite fly 

 {Cory dolus cornutus Linn) seems to be particularly abundant 

 this year, and a large number of specimens have been brought 

 to the rooms by various persons. A small collection of insects 

 was made at Walcott, Iowa, June 10th, while on a visit there in 

 company with Mr. Haupt and Dr. Byrnes. Besides the insects 

 a few small fishes, tadpoles, a crawfish, and a number of speci- 

 mens of Succinea avara. These latter were attached to the 

 decaying stems of weeds and rushes partly immersed in the 

 water. A single dead shell of Planorbis trivolvis was noticed 

 in the same slough. Butterflies continue to be remarkably scarce 

 this year, and during the entire trip to Walcott and back — 

 twenty miles — -scarcely a dozen were seen. 



Mr. J. D. Putnam also made the following renuii-ks : 



On the Young of a Species of Lycosa. 



At the meeting of this Section, May 27th, Mr. Pratt brought in a tin 

 baking powder box containing a number of living land snails, and also a 

 large, dark-colored spider of the genus Lycosa, wiiich was carrying about 

 a large cocoon filled with eggs. The cocoon was fully five-eighths of an 

 inch in diameter, and was attached to the abdomen by the spinnerets. 

 He found it that morning, in company with, others, while looking for 

 shells under a log on Rock Island. I took the box home, but did not look 

 into it again until about June 15th. The eggs had then all hatched, 

 and the young spiders had crawled upon the back of the motlier, and 

 made her appear two or three times as large as natural. It remained in 

 this condition for upwards of a week. I did not disturb the box again 

 until June 22d, when it was noticed that a considerable number of the 

 young spiders had crawled out of a small hole in the top of the can, and 

 had begun to spin webs from the top of the can to the table on which it 

 stood. The spiders were somewhat larger than when I first saw them.
