1220 J. II. Emerton, 



the epigynum is constant and characteristic. It does not extend 

 backward in a point as in ornata and rubra, but is transverse with 

 a deep notch in the middle, Fig. 7 b. 



The male has the cephalothorax narrower in front than the fe- 

 male, and the palpi short, with little resemblance to those of ornata. 

 The tibia is widened into a large process on the outer side, without 

 any sharp teeth. The tube of the palpal organ is short and turned 

 backward, and the other appendages are short and blunt, Fig. 7. 



This species is very abundant under stones all over the top of 

 the Mt. Washington range. The females make thin silk nests and 

 lay their eggs about the first of July, by which time the males are 

 scarce. 



Agroeca pratensis, Em. Trans. Conn. Acad., 1890. 



Females with epigynum like A. rcpens Em. Trans. Conn. Acad., 

 1894, have been fond in several New England localities at the same 

 time with males of pratensis which makes it probable that pratensis 

 and repens are one species with two forms of epigynum.

 (Plate IX, figures 8 to 8 c.) 



The males of this species as well as the adult females are rarely 

 found, because they mature very early in the season. A young- 

 male that had wintered under leaves was taken in Franklin Park, 

 Boston, April 17. and moulted April 22. 



The males differ but little from the females in size and color, 

 but as usual are a little more slender and have longer legs and 

 longer and straighter mandibles. The male palpi have a long pro- 

 cess on the outer side of the tarsus, curved outward and slightly 

 notched at the end, and in some individuals sharply pointed. The 

 palpal organ swells out from the tarsus at the base. The tube 

 begins on the inner side and curves around the base of the palpal 

 organ and along the outer side of the tarsus nearly to the tip, Fig. 8. 



Apostenus acutus, new. (Plate IX, figures 7 to 7-c.) 



Immature males 4 mm. long. An adult male, which is dried and 

 shrunken is of the same size. The cephalothorax is oval and much 

 narrowed in front, so that the head is only one-third as wide as 

 the widest part of the thorax. The eyes are low and arranged as in 

 Agraxa pratensis, except that the front middle pair are much smaller. 

 The front row is slightly curved upward, the middle eyes less than
