New Spiders from New England 

 r,Y J. H. Emerton. 



This paper describes 25 new species and 15 described species of 

 spiders found in New England since the completion of the Supple- 

 ment to the New England Spiders publislied in the Transactions 

 of the Conn. Acad., Vol. 14, January, 1909. Two of these are Euro- 

 pean species apparently lately introduced: Teutana grossa, found in 

 a museum basement in company with T. triangulosa and Epeira 

 diademata, found at Newport, R. I., and evidently well established 

 around the house of the Historical Society and for several blocks 

 along the adjoining street. The two European species of Zilla are 

 now abundant : Z. x-notata ail over Cape Cod and the South shore 

 of Massachusetts and Rhode Island and Z. atrica on Cape Ann and 

 the adjoining country as far south as Fall River and Newport, but 

 not far inland. Zora spinimana, a European spider, has been found 

 several times in one locality only, but in a situation where there 

 seems little probability of its being introduced. Four species first 

 described from the Canadian Rocky Mountains have now been found 

 in Northern New England. Of these Linyphia humilis is abundant 

 among the dwarf firs and spruces at a height of 2000 to 4000 ft. 

 on Greylock, Mass., Mt. Mansfield and Camel's Hump, Vt., Mt. 

 Washington, N. H., and at the sea level in eastern Maine at Eastjiort. 

 Pedanostethus fuscus described first from the Rocky Mountains under 

 the name of Steatoda occurs at several places at about 2000 ft. ele- 

 vation around Mt. Washington. The otlier two species are L3'cosa 

 quinaria and L. beanii found at Bangor and on Mt. Desert, Me. Ot 

 the native species, two were formerly included in others to which 

 they are nearly related, Ceratinella carinata in C. laetabilis and 

 Pisaura brcvijie? in P. (Ocyale) undata. The two species formerly 

 included in Plinirolitlius alarms have been separated and the larger 

 one named P. borealis. The .systematic relations of several species 

 are doubtful, especially Tmeticus armatus Bks. which has pits in 

 the sides of the head like Lophocarenum and male palpi like Erigone 

 or Gongylidium with long setae at the base of the tarsus as in 

 Tmeticus longisetosus and flaveolus. Histagonia nasutus resembles 

 H. (exechophysis) palustris Bks. but has the peculiar character of
