186 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 



hairs marks the middle, and the seminal chambers (Plate XL, 6) are well displayed. Tlie 

 scapus is longer than that of E. gemma, which it resembles. 



Male: Total length, 12.5 mm. (in one specimen 15 mm.); abdomen, 6.3 mm. long, 

 4.9 mm. wide; cephalothorax, 7 mm. long, 5.4 mm. wide; face, 2 mm. wide; resembles in 

 form and color the female. (Plate X., 3 ; Plate XL, 9b.) The legs are much longer relatively 

 than those of the female, as follows: Two specimens, 38 (41) mm., 34.5 (40) mm., 19.5 (23) 

 mm., 29.5 (32) mm. These members are indeed enormously long; in one specimen the first 

 leg measures 48 mm., the second 43 mm. The thighs and femur of legs-I, II, are formid- 

 ably armed with spines ; a slight hook marks coxse-I. The tip of tibia-II is not thickened, 

 nor armed with special clasping spines; but legs-I and II are both provided with numerous 

 long spines, bristles, and hairs, especially on the femora beneath. 



Distribution: I have not collected this spider elsewhere than in the Adirondacks of 

 New York, in New England, and in New Jersey, where it was colonized. It has been 

 taken in Maine, New Hampshire (Mrs. Mary Treat), and is found in New England gen- 

 erally. Dr. Marx records it as collected in Kentucky and Tennessee. Its distribution is 

 probably limited to the more northern belt of States, particularly along the seaboard, and 

 it will probably be found to prefer mountainous and elevated locations.

Female: Total length (two specimens), 17 mm. (21); abdomen, 10 (14) mm. long,

 With some hesitation I have placed this spider as a variety of the well known European 

 E. angulata, which it closely resembles. I note these differences: On the venter, in front 

 of the female genital cleft, are two decided cones (Plate XL, Id), between which the scapus 

 passes.' In a large number, from all parts of the United States, which I have examined, 

 there is no trace of this peculiarity. The American variety, especially in the Southwest, is 

 much larger than the typical European form, and much more hirsute; the legs particularly 

 are thickly covered with bristles and formidable spines, the latter stouter and stronger than 



* I have examined only one specimen, from Moscow, Russia, sent me by Professor W. Wagner, but in 

 this these cones are very decided.
