front and onter edges. The middle of the cephalothorax has a light 

 marking tapering behind to the dorsal groove which is marked by a 

 dark spot. The legs have a distinct fine light line on the dorsal side 

 and are marked all over with small light brown spots without any 

 distinct bands or patches except that the fonrth femur and tibia are 

 darker at the ends. In the adults the markings are less distinct and 

 that of the middle of the cephalothorax darker so as to obscure the 

 lateral stripes. PI. xxvin, figs. 1, la. The males have the same 

 markings but darker. Fig. la. The epigynum, figs. \d, \e, ]/", has 

 a simple opening of various shapes, sometimes with a low and indis- 

 tinct ridge thi'ough the middle. The male palpus has a large and 

 complicated hook under the tibia turned a little toward the outer 

 side so as to be visible from above. Fig. \h. The processes of the 

 bulb are large and dark colored, the under one pointed and directed 

 inward, and the other wide at the end and turned backward to the 

 base of the bulb. Fig. \g. 



Males from Medford and Peabody, Mass. Females, Dedham, Pea- 

 body, Cambridge, Maiden, Salem, Mass ; Simsbur^^, Conn. Both 

 sexes from Brooklyn, Long Island, N. Y., N. Pike. A female with 

 cocoon partly covered by a folded leaf Avas found June 10. 



The specimens in the Museum Comp. Zool. at Cambridge, named 

 by Keyserling, are all females. The male which I suppose to belong 

 to this species is not the limhatus Keys., but probably X. elegans 

 Keys. 



XystiCUS gulosus Keys.

The female is 6 to 8™'" long with the cephalothorax 3""" wide. 

 The color is grayish brown and very uniform, the usual marking 

 showing indistinctly among the fine brown spots that nearly cover 

 the body. The femora are light on the ventral side and have two or 

 three large spots along the middle. The femora are darker toward 

 the end, those of the fourth pair having a distinct black spot near the 

 end. The abdomen has usually only a pair of irregular black lines 

 across near the middle, and several smaller and less distinct behind 

 it. PI. xxviii, figs. 2, 2a. 



The epigynum has an oval oj^ening wider than long, in which are 

 two oval ridges directed backward. Fig. 2c. 



The male palpus has the under tibial process wide and turned out- 

 ward at the end. The tube of the palpal organ is unusually long aud
