Theridium differens, Em. Trans. Conn. Acad. 1892. (Plate I, 
figure 7.) 
The epigynum of this species is wrongly described and figured 
in N. E. Therididae. The openings are really on the outer side, 
as they are in Theridium spirale, and differ only in being a little 
smaller and farther apart. See fig. 7. 
Theridium zelotypum, Em. Trans. Conn. Acad. 1892. (Plate I, 
figure 5.) 
This species has been found in the White Mountains and all over 
Maine, as far north as Moosehead Lake, but not south of Portland, 
Me., and westward as far as Winnipeg, Manitoba. At Monhegan, 
Me., July 1, 1901 adult males were abundant in webs with the 
females under spruce branches. The males are as large as the 
females, and have the abdomen similarly marked. The cephalo- 
thorax, legs and palpi are bright orange color, and the legs only. 
slightly darker at the ends of the joints. The dark middle stripe 
of the cephalothorax is usually shorter than in the female, and does 
not extend forward to the eyes. The male palpus resembles that 
of murarium with all the appendages more elongated, Pl. 1, fig. 5. 
At pairing time the webs do not contain the characteristic tents 
covered with spruce leaves and scales; these are made later and 
in the last of July and first of August are found in nearly all the 
webs, hiding the females and eggs. The females remain in the 
nests with the young as late as September. 
Theridium kentuckyense, Keys. Spinnen Amerikas, 1884. (Plate I, 
figures 6, 6a.) 
The same size and general form as differens and muraritum. The 
colors are less bright than in those species and more like 7. fepi- 
dariorum. The legs are pale, with light yellowbrown, wide rings 
at the ends of the joints, and less distinctly in the middle. The 
cephalothorax is brown, darker at the sides, and lightest between 
the eyes and the dorsal groove, without any stripes. The sternum 
is brown, without markings, and the coxe and base of the fe- 
mora pale.
