Cocoon of Epeira thaddeus, swung upon a line. tough silken tent, and this appeared to belong to the spider, who, moreover, looked as though she might soon make another cocoon. The question was started, but was not solved, does Triaranea weave more than one cocoon? The cocoon was a little ilossy ball, flattened, of course, on the side attached to the rock. I captured one of the fe- males, which cocooned in a box, thus showing that the cocoons above described were those of this species. A cocoon of Epeira thad- deus was sent to me from Vineland, by Mrs. Mary Treat. It had been spun upon some potted ferns within her lodgings. It is a subglobose sac, of a delicate pearl gray color, one-fourth Epeira -j gj millimetres) in diameter. It is attached at the top to thaddeus. . .j ribbon, or rather it widens out at the top into two triangular points, by which it is fastened upon a cord stretched between two sprigs of fern. The egg ball thus swings free. (Fig. 68.) I have secured cocoons of this species, by confinement within the trying box, which differ from the above. They are globular or subglobular masses of flossy yellow silk, about three-eighths of an inch in diameter. I believe that, ordinarily, Thaddeus will be found to weave a cocoon of this sort upon a leaf or other surface, probably enclosing it within a curled leaf, or over- spinning it in the manner of Epeira triaranea. I have not been fortunate enough to identify tlie cocoons of our common Zillas; but a species which I observed in Florida made a cocoon shown at Fig. G9, top of the cut. It was a flossy ball, about three-eighths of an inch thick, and was woven within the silken tent which formed t
