 Pardosa montana Emerton, New Eng. Lycosidse, 1885. 



The specimen described by Thorell was much rubbed and faded, 

 but its size and markings, and especially the shape of its epigynum 

 show it to belong to this species. 



In size it is a little larger than uncata, and smaller than the 

 smallest groenlandica, both of which it resembles when preserved in 

 alcohol. Judging from the best specimens its markings when alive 

 are similar to those of P. uncata (PI. iii, fig. 8), the middle of the 

 cephalothorax and abdomen being light gray with the sides darker 

 and marked with black, and the legs ringed with gray and black, 

 darkest on the femora. The under side is covered with light gray 

 hairs. In alcohol the cephalothorax is almost black, except in the 

 middle behind the eyes, and in rubbed specimens the light markings 

 of the abdomen are absent, except the middle portion over the dorsal 

 vessel. The legs generally preserve the ringed markings. The 

 epigynum (PI. iii, fig. <da) has a middle ridge, narrowing backward, 

 ending in an opaque, brown, blunt point, and at the front end two 

 brown pits, the width of the epigynum apart. This differs from the 

 epigyna of all the other Lycosidae with which it is likely to be 

 found. 



The male palpal organ (PI, iii, fig. 6) resembles that of P. lapidi- 

 cina, the common black Pardosa of New England, the difference 

 being mainly in the larger size and wide end of the basal hook. 



Pardosa luteola, new sp. 



Female 6™"™ long; light yellow with brown markings. The cepha- 

 lothorax has two wide brown longitudinal stripes, united at the 

 front of the head, where they are nearly black, and a fine dark line 

 each side, next the legs. The sides of the abdomen are brown, with 

 a very distinct light spot over the dorsal vessel, and a row of trans- 

 verse light spots behind. The sternum is brown with a light spot 

 in the middle. The abdomen is light beneath, with a narrow brown 

 stripe half its length, each side. The epigynum is bright orange- 

 brown, and the front pair of spinnerets are black. The legs are 

 spotted with brown, the spots sometimes grouped in rings ; the 

 tibiae are the darkest parts of the legs. 



The epigynum has the middle lobe short and wide, but this part 

 is transparent and the overlapping sides are not easily seen, so that it 

 appears narrow. PL iii, fig. ^b.
