Three specimens from Wood's Hole, cephalothorax 6.5-7.5 mm. 

 Nine specimens from Crosswicks, cephalothorax 7.8-10.5 mm. 

 Twelve specimens from West Chester, cephalothorax 8-9 mm. 

 One specimen from Philadelphia, cephalothorax 8.2 mm. 



A large female in the McCook collection (described in my preceding- 

 paper) had a cephalothoracal length of 9.2 mm. 



The color of the vmder surface of the abdomen in the females varies 

 from a pale yellowish-brown with a few small scattered black spots 

 to darker with spots much more numerous, and sometimes arranged into 

 three bands converging toward the spinnerets, to blackish. All these 

 variations are found in the same locality. The sternum varies from 

 brown to black, sometimes with a distinct light median band or an- 

 terior half (all specimens from Wood's Hole and one from West Ches- 

 ter), or without such a band. In the largest female from Crosswicks 

 the annulations on the legs and the converging dark bands on the 

 venter are as distinct as in L. inhonesta (Keys.). 



The males also differ considerably in size, as shown by two recently 

 acciuircd mature specimens from Philadelphia: 



Length of cephahjthorax, 4.3 mm.- 6.6 mm. 



Length of abdomen, 4 "-5 " 



Length of first leg 16 '' -24 



Length of second leg, 16.2 " -22 " 



Length of third les, 15.5 " -20 



Length of fourth leg, 21 " -27 



The color in life of these two males is as follows: Cephalothorax 

 blackish, a narrow buff-brown median line extending from the fore- 

 head to the end of the thorax, barely as wide as the space between the 

 eyes of the second row, in one specimen to each side of the anterior 

 end of this stripe a narrower parallel stripe; an interrupted broader, 

 marginal band of the same color, and composed of long hairs. Sternum 

 pale greenish, covered with long hairs. Abdomen above anteriorly 

 with a blackish median mark largest just l:)ef()re its termination at 

 the middle of the dorsum, l^ordered by Ijuff-brown broad stripes, and 

 each of the latter by a blackish stripe which extends to the spinnerets; 

 posterior portion of the dorsum blackish, with indistinct buff-brown 

 spots, in one specimen with a pair of white s])ots; sides pale yellowish; 

 venter pale yellowish, in one specimen with black spots. Legs pale 

 yellowish-brown, metatarsus of the first pair blackish, distal end of 

 the tarsi of the other pairs blackish. Palpi colored like legs, but the 

 tarsi blackish on the inferior aspect. Chelicera yellowish-brown,
