428 J. H. JEmerton — Canadian Spiders. 



In the male, the cephalothorax and abdomen are darker, and the 

 legs lighter, except at the base, where the upper sides of the coxae 

 and part of the femora are darker than in the female. The head 

 and palpi are black, with the patella and tibia a little lighter on top, 

 and probably having some light hairs when alive. 



The male palpi are large, the tarsus being about as long as tibia 

 and patella. The palpal organ is dark colored and projects a little 

 from the bowl of the tarsus. The basal hook is rounded in the 

 middle and curves in a point toward the base, PI. in, figs. V, 7a. 



This species is about the same size and color as P. pallida Em., of 

 New England. The sternum is dark, with a light median stripe on 

 its front half, while in pallida the sternum is light with four dark 

 lines or rows of spots converging behind. In the males, the palpi, 

 mandibles, and maxillae are darker than in pallida. The epigynum 

 resembles that of pallida^ but is shorter and wider. The male palpi 

 have the basal hook short and turned down at the point, while in 

 pallida it is long and slender, and extends across the whole width 

 of the palpus, supporting the tube.
