Length of abdomeu, d, 5.2 mm. ; ?, 8.5 mm. 



Length of first leg, d", 19 mm, ; 9, 19 mm. 



Length of second leg, cf, 17 mm. ; ?, 18 mm. • 



Length of third leg, cf, 16,5 mm.; ?, 17.2 mm. 



Length of fourth leg, d, 23 mm. ; ?, 23.3 mm. 



These are dimensions of unusually large individuals. In the same 

 locality occur mature ? 9 with a cephalothoracal length of only 

 5.5 mm. 



Color ill Life, <d. — Cephalothomx above black, a grayish-brown 

 median band from the posterior eyes to the end of the cephalo- 

 thorax, a broader marginal band of the same color divided longi- 

 tudinally in its anterior half by a black strii^e, the ventral margin 

 of the forehead and the space between the second eyes also gray ; 

 all these grayish markings are due to long haii's. Sternum uearlv 

 black, covered with grayish-brown hairs. Abdomen black on its 

 anterior declivity, a broad light band extends on the dorsum from 

 the anterior end nearly to the spinnerets where it ends in a point, 

 this band buff-brown anteriorly and nearly white at its posterior 

 end ; in the anterior half of this baud is a dark-brown mark edged 

 with black and terminating bluntly at the middle of the dorsum, and 

 on each side of the median light band is a row of large black spots; 

 the sides are buff above and gray below ; the venter nearly white 

 with two black stripes diverging from the spinnerets forward, and 

 each at its antei'ior end (just behind the lung slits) deflected 

 mediad at a i-ight angle so as almost to meet its fellow of the oppo- 

 site side. Spinnerets reddish-brown, blackish at base. Chelicera 

 almost black, with buff hairs anteriorly and a light prominence at 

 the supero-lateral angle. Labium Ijlack. Maxillm brown. Jjcys 

 yellowish-brown with buff hairs on the femora, shorter white hairs 

 elsewhere, the latter thickly grouped on the tarsi and metatarsi of 

 the first and second legs. Palpi colored like legs. 



The 9 9 are colored somewhat less brightly than the dd. The 

 coloration is quite variable in this species. Sometimes the dark 

 stripe included in the pale median band of the abdomen is lacking. 

 The coloration of the venter is particularly variable; in four 

 specimens the venter from the epigynuni to the spinnerets is en- 

 tirely black with no buff markings ; in four othei-s there is a pair 

 of buff spots in the black ; two others have one large buff spot in 

 the venter; others have the black in the shape of a U on a light 

 ground. All these colorations are found in the same locality.
