New Spiders from Neiu England, XI. 137 



raiicli spread apart at tlie end, and have a thick tooth half as long 

 as their diameter, only a short distance from the claw. In some 

 individnals there is a smaller tooth between the large one and 

 the end of the mandible, but it varies in size and position, and is 

 often absent on one or both sides. Fig. 2e. PL I. The mandibles 

 are shorter and less divergent than in sexpunctatus, and less vari- 

 able. The palpi of the male resemble closely those of sexpunctatus. 

 This species is swept from low bushes or sifted from dead leaves 

 on the ground. Crawford Notch, Franconia !N^otch, Adirondacks, 

 Aroostook County, Maine, Maine Woods, south to Portland, Maine, 

 and Manchester, N. H., often in company with T. sexpunctatum, 

 with which species it has been usually confused. 



Theridion sexpunctatum. Em. 



This species is now known across the continent to the Rocky 

 Mountains, VancouA'er and Sitka. The long mandibles of the 

 male are found to vary in length and shape but without any rela- 

 tion to locality. The male mandible always has a large tooth 

 on the inner side just beyond the end of the maxillae and the 

 variable part is the distal end beyond this tooth. Sometimes this 

 is as long as the basal part and tapering and divergent and it then 

 has three or four teeth differing in size, position and number 

 sometimes differing on opposite mandibles of the same individual. 

 In others the distal part of the mandible is half as long as the 

 basal and the teeth are very small. In others the distal part is 

 still smaller. One from Sitka in the collection of Nathan Banks 

 has mandibles like this but still shorter. Figs 3, 3a, 3b. PI. I. 



Tmeticus rectangulatus. new sp. 



A translucent spider 1.5 mm. long, resembling T. entomologicus 

 from Tyngsboro, Mass., 1911; T. digitatus, Em., from Ithaca, 

 N. Y., Journal N. Y. Ent. Soc, 1914, and T. acummatus, Em., 

 from New Jersey, Bulletin Am. Museum, N. Y., 1913. It differs 

 from these species in the tibia of the male palpus, which is truncate 

 and has three small teeth across the end. Fig. 4. PI. I. 



One male each from Mt. Mansfield, Vt., and Brimswick, Me. 



Linyphia limitanea. ne^v sp.
