196 J. IS. Emerton — New England Drassidm, 



Hahnia bimaculata, new sp. 



Plate VII, figures 8, 8a, to 8/. 



Length, 2-5""°. Eyes lai-ge, both rows with the lateral eyes low- 

 est. Lateral eyes much nearer together than the middle pairs. 

 Front eyes a little the larger, both rows strongly curved, the middle 

 eyes highest. Maxillae short and wide, the front edge straight 

 except on the inner corner. Sternum as wide as long, widest oppo- 

 site the second legs. The spinnerets are long, the terminal joints of 

 the outer pair nearly as long as the basal joint. The tracheal open- 

 ing is nearer the epigynum than the spinnerets. Plate vii, fig. 8. 



The cephalothorax, sternum, and mouth parts are reddish brown. 

 The abdomen is light gray with many irregular pale spots and a 

 double row of pale oblique markings in the middle. In the middle 

 of the front half of the abdomen are two orange colored spots. The 

 under side of the abdomen is pale with a few gray spots. The legs 

 are pale with gray rings, two rings on the femur, tibia, and metatar- 

 sus. The skin over the epigynum is very transparent and shows 

 two convoluted tubes almost always unsymmetrical, figs. 8c, c?, e, _/'. 

 The male palpus has on the outside of the tibia, near the end, a 

 pointed process as long as the diameter of the tibia. At the base of 

 the patella on the outer side is a small pointed black process curved 

 a little forward, fig. 8^. The tarsus is nearly as wide as long but 

 slightly pointed at the tip. The palpal organ is flat with a long 

 thin tube extending along the inner side around the end, fig. 8a. 



Common under dead leaves. Massachusetts, Connecticut, and Mt. 

 Washington, N. H. 



Hahnia radula, 



new sp. 



This spider resembles II. bimaculata but is nearly twice as large. 

 On the under side of the first and second legs and pal])i of the male 

 the hairs are raised on short transverse ridges so that the leg ajjpears 

 serrated when seen from the side. Plate vii, figs. 10, 10a. The gray 

 markings of the abdomen and rings around the legs are less distinct 

 than in hiinaculata. The little spine at the base of the patella of 

 the male palpi is shorter than in bimaculata and sharply turned for- 

 ward. The appendage of the tibia is the same as in bimaculata, and 

 the tarsi and palpal organs are very similar. 



One male, Jaffrey, N. H., Aug. I.
