Color (in alcohol). — Cephalotho7'ax above with a very narrow white 

 median line in the eye area extending back to the dorsal groove; the 

 extreme margin white; a broad siibmarginal band of orange on each 

 side, not extending to the head; a small reddish-yellow area around 

 the dorsal groove (and extending back to the posterior margin of the 

 thorax as a narrow band), from which broad radiating bands extend 

 to the submarginal band, about fom* of these bands on each side, and 

 each band narrowly white in front, black behind this, then reddish- 

 brown in its posterior half. The ocular area is blackish; the clypeus 

 and cheeks whitish above, poster o-ventral margin of each cheek with 

 a black spot. Sternum deep black. Abdomen above on its anterior 

 half with a broad median dark band edged with black, this band nar- 

 rowest anteriorly with sinuate margins and concavely truncated pos- 

 teriorly; it is bordered b}" orange-brown. At each antero-lateral mar- 

 gin of the dorsum arises a broader, interrupted black stripe which 

 extends almost to the spinnerets, and in its posterior half is simply an 

 area of black spots. Behind the median band is a series of four nar- 

 row, transverse black bands, whose lateral margins confluesce with the 

 lateral black stripes. Sides orange-brown, marked posteriorly with 

 blackish spots, ^^enter pale greenish, with a sharply boimded, deep 

 black band extending from the rima epigastrica in front to a little an- 

 terior to the spinnerets behind, this black covering the whole venter 

 behind the lungs but not extending up the sides. Chelicera black with 

 orange hairs anteriorly, labium and maxillce black with paler tips. 

 Legs above yellowish, femora of I and II with two almost contiguous, 

 parallel dark lines above, and another on the posterior aspect, these 

 represented by lines of black spots on III and IV; the patellae and 

 distal ends of the tibiae are brownish, the metatarsi and tarsi of I and II 

 pale brownish. Below the coxae are chocolate-brown, the femora A-ery 

 pale yellow, the patellae and distal ends of the tibiae deep black, the 

 metatarsi and tarsi reddish-brown. Palpi yellow, femora above with 

 two longitudinal darker stripes, patella below slightly darker than 

 above, whole tarsus almost black. 



Comparisons.- — Of all the species of the genus it comes closest to 

 texana, but apart from the differences in coloration and the palpal 

 organ it may be distinguished by tarsus I being more than one-half the 

 length of the metatarsus, while in texana this joint is decidedly less than 

 one-half this length.
