. American spiders and their spinning work. A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits. Spiders. Fig. 189. Cocoon of Huntsman spider, as clasped and carried by the mother. (View from above.) flat circular plate which is attached to the object, rock, bark, or wood on which the cocoon is spun; and, second, a convex covering which fastens above the eggs like a cap. The inside is lined with pure white silk, but the outside is often of a grayish brown, and ap- parently is purposely soiled in order to subdue the color. Usu- ally there is no flossy pad- ding for the eggs. I am not sufliciently acquainted with co- coons of this tribe to enter largely into a comparison with those of others, but the forms known to me and above de- scribed are probably typical, and substantially represent the maternal industry of the Laterigrades of the United States, and i)robably of the globe. The well known tropical species, Heterapoda venatoria, or the Hunts- man spider, is one of the largest of the Laterigrade species, and may 2>roperly be classed with the spider fauna of the United States, "^^^ as I have specimens from Florida. It abounds in the West ""^ ?1 Indies. The cocoon is a large double convex or piano convex 1118(11 rlBb- _ . 1 ,1 • 1 erapoda. object, resembhng those of Ihomisus and other species when woven against various surfaces. It appears, however, to be car- ried by the mother; at least, one female {)reserved by me in a box wove a cocoon of this sort which she carried in the manner represented at Fig 189, which gives a view from above, and Fig. 190 a view from beneath. The button like cocoon was put beneath the body, which it almost entirely covered; at one end it appeared to be attached to the spinner- ets, and at the other was held tightly by the outspread palps. The mother made an awkward appearance as she straddled about the box, holding her Fio. 190. Cocoon of Huntsman spider, c
