SOME OBSERVATIONS ON THE WEBBING CLOTHES 

 MOTH {TINEOLA BISELLIELLA HUM.).i 



By M. T. Smulyan, 

 U. S. Bureau of Entomology, Melrose Highlands, Massachusetts. 



Two larvae, 7 and 11 mm. long, respectively, discovered working 

 in the writer's overcoat October 25, 1917, were placed in a glass jar 

 lined, except at the top, with a layer of gray felt, and placed in his 

 sleeping room where his clothes-closet was located, for rearing and 

 observation. The room was then receiving, and continued to do so 

 until well into April, some furnace heat during the day, but was 

 quite cool during the night and early forenoon, when it was freely 

 ventilated. Owing to the writer's regular duties, most of the 

 observations dealing with the behavior of the larvse were made 

 at the close of the day, by artificial light — ^which, as will be seen 

 below, may have had a bearing on the behavior of one of them. 



October 28, both larvse feeding freely. November 1, the smaller 

 within a substantial cocoon, at the bottom of the jar. November 

 2, had moulted — found the cast shell of the head just outside the 

 cocoon, at one end, and the remainder of the skin just outside at 

 the opposite end — but when the jar was brought closer to the light 

 (gas) in order to verify the observation, the larva hurried out of the 

 cocoon and crawled away. November 4, the same individual in 

 the process of constructing another cocoon ; the other — the larger — 

 was still feeding freely. November 7, found the latter encased in a
