Supplement to the New England Spiders. ill 



such as probatus and trilobatus, approach Erigone by their wide 

 maxillae and long palpi and the tibia widened toward the tarsus, 

 and the males have a strong single spine on the front of the man- 

 dibles. Maximus, tibialis and brunneus resemble each other in size 

 and proportions, but differ in their mandibles and palpi. The other 

 species have little in common except their general size and color, 

 arrangement of eyes and form of mandibles and maxilla?. 



Erigone now includes four species ; longipalpis, dentigera, autum- 

 nalis and the new brevidenlatus with wide maxilla;, large mandibles 

 and long male palpi with widened tibia, and a spur directed down- 

 ward on the patella. 



In the Therididct there are but few additions. Tlieridium ken- 

 tuckyense has been found in a few places. The male of T. zelo- 

 typum is described and the species found to be common in Maine 

 and New Hampshire. Latrodectus mactans has been found in several 

 localities, but is nowhere common. The new Enoplognatha rngosa 

 has been found rarely but in localities far apart. The same is true 

 of the new Pedanostethus pumilus, and P. spiniferns. 



In the Agalcnid<v, Hahnia brunnea is described from a single 

 specimen, but there is a second one in the collection of Mr. Banks. 

 Cryphceca montana appears to be common in northern New Hamp- 

 shire, and from description is very near the C. peckhamii Simon of 

 the Pacific coast. 



The larger Clubionas have been better defined and new figures 

 are given of the epigynum of several species. The two new species 

 are one from a single specimen C. spiralis and the other C. pre- 

 matura a common species from the summit of Mt. Washington, the 

 female of which has long been known as a variety of C. ornaia Em. 



The North American Lycosidce and Pisauridce have been described 

 and their classification much improved by T. H. Montgomery in 

 Proceedings of Philadelphia Acad., 1902-3 and 4. Lycosa relucens 

 Montg. is a common species in New England. Dolomedes idoneus 

 Montg. and D. fontauus Em. have both been described as D. tene- 

 brosus Hentz, which agrees equally well with either. The new 

 D. vcrnalis appears to be common in Maine and New Hampshire. 

 Pirata remains a difficult group and each author has his own species. 

 P. minuta is the most distinct, montana and insularis have been 

 again identified and three new species are described. In N. E. Ly- 

 cosidae 1885 I have described under the name of L. nidifex what 

 I now consider as two species named by Marx in the Am. Naturalist, 

 1881. L. nidifex and L. Pikci. Nidifex is the inland species which 

 ordinarily makes a ring or turret at the mouth of its burrow ; Pikei
