 showing a tiny white cocoon suspended by two or three slen- 

 der threads from a small branch of evergreen. The author 

 thought it might be the cocoon of Hyptiotes, and suggested 

 further observation to verify the conclusion. 



It was my good fortune the past year, during the progress

 cocooning habits of spiders in general, to settle the question 

 finally, though not in favor of the cocoon referred to above. 

 That probably belongs to one of the smaller Theridiids. Two 

 females of Hyptiotes, imprisoned in glass tubes the first week

 cocoon each on the cork stopper. After that, by careful search,
