make a round patch of web with the hole near the center, but usually 
the shape of the web depends on that of the plant on which it is 
made. The principal threads of the web, if they are parallel or 
radiating slightly, are often crossed by a number of parallel short 
threads, like a segment of a web of Zpeira (PI. x1, fig. 3) and the 
curled band is carried back and forth on these as in the figure of 
the web of Amaurobius. Pl. x, lg.

Length about 3"". The cephalothorax is dark brown, a little 
lighter on the top of the head with a few gray hairs in longitudinal 
rows. The abdomen resembles that of D. volucripes Keys, but the 
middle dark markings are wider in front and more broken behind. 
In the middle of the front half is a wide dark patch, extending about 
to the middle of the abdomen. Behind this are two rows of dark 
spots connected by transverse lines, more or less complete, forming 
an Epeira-like marking. PI. 1x, figs. 1 to le. 
The markings of this species and of volucripes vary greatly, so 
that they often cannot be distinguished by them. The metatarsus 
of the hind legs is nearly straight, not so much curved as in volw- 
cripes. : 
The males are darker, but usually have the same markings. Their 
abdomen is smaller than that of the females, but the cephalothorax 
is fully as large. The male palpi resemble those of volucripes Keys. 
The tibia is similar in shape, but is proportionally longer, and the 
two-spined process shorter than in volucripes. Pl. 1x, Lf, 14g. 
This spider is found all over New England. It is the most com- 
mon species on fences, but is found also on plants, and, in winter, 
under leaves. It sometimes tries to fly, oftener in the spring than in 
the fall, which is the usual flying time of most spiders. I have speci- 
mens from Mt. Washington, N. H.; Portland, Me.; Salem, Mass.; 
Albany, N. Y.; New Haven, Conn.; Wood’s Holl, Mass.; and several 
places around Boston. 
A female in the Museum of Zodlogy, Cambridge, Mass., named by 
Keyserling, D. arwndinaceocides Keys., is perhaps this species. It 
has the abdomen very much distended, so that the epigynum shows 
much plainer than usual. The spider first described by Keyserling 
as D. arundinaceoides came from Colorado, and I have not seen it 
and do not feel sure enough of its identity to adopt the name for this 
species.
