Locality. — New Hampshire !. 



"This very distinct species is abundant among the moss and low 

 slirubs on the upper part of Mt, Washington, New Hampshire, and the 

 neighboring mountains," 



The descriptions above are based upon the type specimens. 



Lyoosa fumosa Emerton, 1894. 



(Tr. Conn. Acad. Sci., 9, p. 421, PI. 3, figs. 1, la.) 



Female. — Cephalothorax nearly black, of a reddish tinge. Chelicerce 

 the same color as cephalothorax. Labium and endites lighter in 

 color than cephalothorax, pale distally. Sternum similar to cephalo- 

 thorax but lighter. Coxm of legs beneath brown, clearly paler than 

 sternum. Legs a little lighter and more reddish than cephalothorax, 

 the femora slightly darker than other joints, all joints unmarked 

 or the femora with a few faint light spots. Palpi like legs. Cephalo- 

 thorax, sternum and legs clothed with gray-brown pubescence, being 

 probably bleached in the alcohol. Ahdomen entirely black, slightly, 

 paler beneath especially in front of lung-slits, clothed with brown 

 pubescence; pubescence of entire bod 3^ and legs rather dense. 



Cephalothorax comparatively low, angularly depressed in profile at 

 dorsal groove. Face one-half as high as the length of the chelicerje. 

 Anterior row of eyes of the same length as the second or very nearly so, 

 nearly straight, the center of lateral eyes being but slightly lower; 

 anterior median eyes slightly smaller than the lateral ; the tubercles of 

 the lateral eyes increase their apparent size: anterior median eyes 

 their full diameter apart, same distance from the lateral eyes, more 

 than their diameter f i-om eyes of second row ; anterior lateral eyes more 

 than their diameter from eyes of second row (nearly one and one-third), 

 closer, but little more than diameter, from front margin of clypeus; 

 eyes of second row not fully their diameter apart; eyes of third row 

 three-fourths as large as those of second; quadrangle of posterior 

 eyes a little wider in front than long (11.5 : 10) unusually wide behind, 

 being there nearly twice as wide as long (19 : 10), the pars cephalica 

 being wider than usual and the third eyes set well out laterally; the 

 quadrangle of posterior eyes between one-fifth and one-sixth as long as 

 the cephalothorax (about 1 : 5.6). 



Lower margin of the furrow of the chelicerce with three stout teeth, 

 the third being a little stouter than the others; the first two with 

 posterior face more curved than the anterior and so appearing bent 

 forward; upper margin with three teeth, the first minute, the middle 

 stout and acute as usual, the third as long as median but more slender.
