Pechliam — Spiders of the Family Attidae. 341 



a dark colored ceplialotliorax Avith a Avliite band just behind the 

 first row of eyes, another, shorter and somewhat crescent-shaped, 

 behind the third row, and wide white bands on the sides, which 

 run forward and curve around in front of the dorsal eves. The 

 markings on the abdomen are less constant, although the gen- 

 eral impression is of a dark background transversely banded 

 with white. In some cases the anterior and posterior ends are 

 dark bevond the white bands. The central white band is be- 

 hind the middle of the abdomen. The sides are entirely white 

 and a slender, central, longitudinal vdiite line, which is often 

 indistinct, runs over the dorsum throughout its length. In 

 many specimens the white regions at the anterior and posterior 

 ends are indistinct, and the central white band has a small dark 

 triangular spot in the middle. In some cases the abdomen 

 might be described as white with two dark transverse bands. 

 There are no fringes on the legs. 



When dry, the more perfect specimens show the cephalic part 

 covered with snow^ white hairs, while bright red hairs grow on 

 the clypeus and cheeks and around the middle eyes of the first 

 row, the clypeus having an edge of white hairs. The small, 

 vertical, iridescent falces have some short white bristles on the 

 front surface. The palpus has snow vvdiite hairs on the femur 

 and patella. The sanne joints on the first leg are of a beauti- 

 fully metallic steel blue color. The abdomen is jet black with 

 a transverse white band near, but not at, the anterior end, and 

 another behind the middle, and a patch of white just above the 

 spinnerets. In some specimens the black parts are covered with 

 yellow hairs. In one male the hairs on the abdomen and the 

 top of the cephalothorax, instead of being white, are of the soft 

 yellowish color known as ''old gold.'' 



In this species the quadrangle of the eyes is plainly wdder in 

 front than behind, and the eyes of the second row are very 

 slio'htly nearer the third than the first row. 



We have tvro males and numerous females from Brazil, col-
