Spiders. ajSNEKAL COCOONING HABITS OF SPIDERS. 151 black. I named the species Attus opifcx, but according to Professor Peck- ham it belongs to the genus Pliidippus.^ I present in this connection a fac simile drawing of perhaps the earliest sketch of a Saltigrade cocooning nest. July 26th, 1745, Baron De Geer found among the needle like leaves of a pine tree a large, oval cocoon nest of white silk, which was woven around the branch and interlaced with the leaves. (Fig. 18G.) The spider was inside along with her little ones, who were present in great number. In the middle of the cocoon nest, at the side, was a door, at which the spider stayed on guard ; but generally she was within the tent with her little ones, preferring the back or middle part thereof, near the supporting branch. De Geer found at the entrance detritus of flies and other insects which had been devoured by the mother, such as the legs, wings, etc. The spiderlings accompanied the mother, and appeared to live on good terms with her. They were about a line long, but otherwise quite resem- bled the mother, having black bodies and brown legs. They moved with great vivacity and appeared to be nourished, in common with their mother, by the prey captured by the mother. The species appears to be Dendry- phantes hastatus Clerck.'^ VI. Among Laterigrades a very general habit is to si)in a piano convex cocoon of tough silk fibre, which is attached to some surface. Sometimes a light shelter tent is spun over this, and the spider will be found dwelling within. (See Vol. I., page 347, Fig. 338.) Thomisus cristatus Clerck, of Europe (Xysticus audax Koch), secludes her- self in the leaves and stretches some isolated threads ai'ound her, and there sometimes she sus- pends herself. In this retreat the female lays her eggs in a flat cocoon, one-fourth inch in dia
