A favorite site of this sort is the trunk of an old hickory tree, whose flaky outer bark, curled up at the free ends, offers an acces- sible retreat. A cocoon of Insularis, in my col- lection, spun within a small paper box, is a globular ball of Cocoon of ijq silken plush three- Insularis. -i. • i • i- fourths or an nicli in di- ameter and of a light yellow color. (Sec riate IV., Vol. II.) It is hung against the side of the box (Fig. 56) in the midst of a maze of short right lines an inch and a half wide and high. These lines are knotted to- gether at innumerable points, which are marked by little white dots. This meshed envelope extends nearly to the cocoon, and certainly appears to be a sufficient barricade against hymenopterous invaders, although it was not able to save the eggs from those universal and well nigh irresistible pests of collections, the Dermestida). I have another cocoon of this species similarly disposed within an inverted glass tumbler, under which' tlie mother had been confined. She attached herself to the bottom of the glass (the top when inverted), and, as is the custom of her kind, hung there back downward until the period of cocooning. (Fig. 57.) Not long after she died, and her dried up form is partly shown in tlie drawing. The spots upon the glass represent the points of attachment for the supporting lines of the co- coon, and are little pats of adhering silk. Sometimes cocoons are found laid against a leaf which has been dra
