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

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

If this be fairly representative of the prevailing habit of this widely 

 distributed species, we have among the Laterigrades also an example of
