364 J. H. Emerton — Spiders of the Family TJiomisidm. 



The male palpus has the tube stout and extending almost entirely 

 around it. The processes of the bulb are small and the posterior 

 one blunt and notched at the end. Fie-. Id. 



This is a very common species in grass and low plants all over 

 New England, In Psyche, vol. v, I have described the pairing of 

 this species. The female held herself on a blade of grass, head 

 downward, with the abdomen turned away far enough for the male 

 to reach under, from above, to the epigynum, 



Xysticus graminis, new sp. 



Plate XXIX, figures 2-26. 



This species resembles in color and markings the male of X. 

 trlguttatiis. It is a little larger and darker, and there is less con- 

 trast between the light and dark portions. The legs are shorter and 

 stouter and the patella and tibia of the first and second legs, as well 

 as the femur, are dark brown. The ends of these legs, as well as 

 the third and fourth pairs, are light yellow brown, not as white as 

 in trlfjvttatus. The dark bands on the cephalothorax are not so 

 distinctly broken into black marks as in triguttatus^ nor are the 

 thi'ee spots as distinct. The markings of the abdomen do not extend 

 across the front half and the lighter parts are not as white as in 

 trigiittatus. PI. xxix, fig. 2. 



The male j^alpus resembles that of triguttattis, but the processes 

 of the bulb are longer and both pointed and directed inward. 

 Fig. 2a. 



The female is 6'"'" long and the cephalothorax is 3""" long and 3""" 

 wide. The legs are short and stout. The color is dark brown with 

 very small light markings. The front of the head is wide and light 

 colored, with a distinct white band under the upper row of eyes, 

 behind which is a very dark brown line. The dark patches on the 

 sides of the thorax are partly divided into two, the inner halves 

 ending in darker spots, as in trigiittatus and stomachosiis, but less 

 distinctly marked. In the middle of the cephalothorax is a triangu- 

 lar dark area narrowing to a dark spot behind, and each side of this 

 a light line narrowing forward to the eyes. The abdomen is dark . 

 with alternate narrow darker and white markings across the hinder 

 half and obliquely down the sides. The legs are covered with small 

 brown spots. The first and second femora are lighter on the front 

 side, and the third and fourth legs have a light line on the dorsal 

 side. The femora of the third and fourth legs have a dark spot at 

 the end. The under side is dark with small brown " spots, and the
