Tmeticus plumosus Em , New Eng. Therididse, 1882. 



Montreal. Mt. Washington, N. H. Beverly, Massachusetts. 



Tmeticus pectinatus, new sp. 



This species resembles closely T. plumosus, but is twice as large. 

 The eyes are smaller in proportion to its size. The length is nearly 

 3™"^ and the form and color are like plumosus. The male palpi, 

 which are usually the best marks of species in this family, resemble 

 closely those of T. plumosus, but the tarsus is more angular (Plate ii, 

 fig. 4), and the tarsal hook a little shorter and wider. The general 

 form of the palpal organ is like that of plumosus, but the feather- 

 like appendage is thicker and has along its middle several long black 

 teeth (PI. II, fig. 4a). The mandibles have the front tooth longer 

 (PI. II, fig. 45). 



Two males from Laggan. 



liinyphia humilis, new sp. 



Male and female S'o"^"^ long. The cephalothorax of the female is 

 low and without markings except a little darker color around the 

 eyes and along the edges. The cephalothorax and legs are light 

 brownish yellow, darker and grayer toward the tips. The abdomen 

 is white with the usual middle purplish brown marking (PI. ii, fig. 3) 

 increasing in width from front to back without any break across it 

 like that in marmorata. The under side of the abdomen and the 

 sternum are very dark brown. 



The epigynum has tlie usual wide opening partly divided by a 

 short process in the middle (PI. ii, fig. 3c). 



In the male the head is a little elevated and the mandibles longer 

 than in the female (PI. iii, figs. 3a and 3^), the legs are longer than 

 those of the female but shorter than the legs of marmorata (PI. iii, 

 fig. 3a). The legs and cephalothorax are light orange brown. The 

 abdomen is black or dark gray without markings. The male palpus 

 is also black at the end and resembles that of L. marmorata.
