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 1, 

 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, PI. 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 murarium. The 

 colors are less bright than in those species and more like T. tepi- 

 dariorum. The legs are pale, with light yelluwbrown, 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 coxae and base of the fe- 

 mora pale.
