NEW SPIDERS FROM CANADA AND THE ADJOINING STATES, No. 2. 



HV J. II. EMERTON, BOSTON, MASS. 



The fust pajXT of this series was published in August, 1917, and described 

 a numlxT of spiders from tlie Pacific coast, eastern Canada and northern New 

 York and New England, part of them collected in the summer of 191 (>. The 

 present paper describes a few new species collected and identified from the 

 same parts of the country since 1916. In addition to the new species, the male 

 of Fardosa vancotiveri, described in the paper of 1917, has been found, and its 

 palpus is now figured. Diplostyla canadensis Emerton, described in Trans. 

 Conn. Acad., 1882, from Montreal, has been again found, at Lake Tear on Mt. 

 Marcy in the Adirondacks, N.Y., at an elevation of 4,500 feet. 

 Lophocarenum minakianum, n. sp. 



Hardly 2 mm. long. Light brown with the legs and palpi and underside 

 of the abdomen pale. The whole upper half of the abdomen is thickened and 

 covered with small depressions in which are minute hairs. The head of the 

 male has a hump which carries the posterior middle eyes. It is about as high 

 as wide, and rises abruptly before and behind. It is rounded on top and has a 

 slight groove in the middle, but is not as deeply divided as in L. sculptuni Em., 

 (Can. Ent., Aug., 1917,) which this species closely resembles. At each side of 

 the hump is a deep groove as in sculptuni and excavatum. The male palpus '"s much 

 like that of scidptiim, but the process on the top of the tarsus is longer and more 

 narrowly pointed. (PI. 7, Fig. 1, a and b.) ^ 



Minaki, Ontario. Sifted from leaf mould near Minaki Inn. 



Ceratinopsis obscurus, n. sp. 



Male 2 mm. long. Legs and cephalothorax yellow brown and the abdomen 

 dark grey. The cephalothorax is nearly as wdde as long and narrowed in front. 

 The male palpi resemble those of C. nigripalpis, but the outer process of the 

 tibia is wide and flat. The tarsus has, as in nigripalpis, a wide, thick ridge on 

 the outer edge, at the side of which is a -narrower groove. The palpal organ 

 resembles that of nigripalpis and nigriceps. (PI. 7, Fig. 2, a, b.) 



In leaf mould in pine and birch woods at Minaki, Ontario. 



Grammonata semipallida, n. sp. 



Scarcely 2 mm. long. Legs pale, cephalothorax but little narrowed in 

 front, pale on the hinder half and darker gray in front. The palpi are also 

 dark grey. The abdomen is gray, pale in front and marked behind with alternate 

 dark and light transverse spots. (PI. 7, Fig. 3, a.) The male palpi are large and 

 the tarsus round. The tibia has a short, blunt process extending over the 

 tarsus, which has a distinct groove in which the process fits. The tarsal hook 

 is curved in a half circle. The tube of the palpal organ is slender and abruptly 

 curved backward in the middle. (PI. 7, Figs. 3, b, c, d.) 



Winnipeg, Manitoba, June, 1917. F. W. Waugh. 



Diplostyla crosbyi, n. sp. 



Male 4 mm. long. First femur 3 mm. Height of head and mandibles 

 nearly equal to length of cephalothorax. (PI . 7 , Fig. 4, a.) The cephalothorax and 

 legs are brown and the abdomen gray with light markings in pairs, as in nigrina. 

 The tarsus of the male palpus is but little longer than wide. The tarsal hook 

 has a sharp angle near the end and the terminal part is thin and flat and curved,
