Mrs. Treat found the males of our Triangle spider at home with the females during two seasons. They were not in webs of their own, but always in the upper corners of the nets of females where the foundation lines are fastened to the trees. They were thus opposite their mates, who were waiting beyond the apex, and apparently were watching all their movements with great interest. This is the custom with males of most Orbweavers during the pairing season. It is a mis- take, however, to suppose that the males do not spin snares. I have fre- quently found them upon webs of the same construction and operated in the same way as those of females. At one time, I found in a fir tree a group of ten males, with their snares spun close together. A curious behavior was noticed in a Triangle spider observed in a pine wood in the Allegheny Mountains. Numbers of snares were there found on liemlock trunks and dead standing saplings. I cut the trap- IVEuscTil8>r • c7 X o 1 Rie-id't ° ° ' these webs to see how it would aifect the spider. She was hanging at the time with her hind legs quite near the trunk of a tree. Instead of dropping downward when the support of the fore part of her body was broken, she simply settled backward a little so that the end of her abdomen rested against the tree. In this position her body extended straight out from the trunk in a line at right angles thereto. The fore legs were slightly bent and held but a remnant of the trapline, which was greatly ruffled in the man- ner of a taut string when suddenly untwisted. Both pairs of hind legs in the meantime were holding tightly to t
