128 PECKHAM. [Vol. 2, 



Some of the females are much like vernalis, having 

 speckles all over the abdomen, four dark dots, a dark, transverse 

 line in front of the spinnerets, and, behind this line, two small 

 chevrons. Others are more like mitrata, having two pairs of 

 dark spots on the anterior and middle part of the dorsum and 

 one large spot behind these and just in front of the dark, trans- 

 verse line. The whole spider has a light ground color, thickly 

 covered with white down, which is mixed with more or less 

 orange or rufous color. In the abdomen this color appears in 

 speckles. In the cephalothorax it is more evenly mixed with 

 the white. Just back of the lateral eye, on each side, is a stiff, 

 black bristle, which stands out sideways and which is enlarged 

 at the end (mitrata also has bristles in this position). There 

 is a black line around the lower border of the cephalothorax. 

 The pattern on the abdomen, which is most distinct under 

 alcohol, is identical with that of mitrata. There are three or 

 four dark chevrons on a light ground, the first one being 

 divided to form two spots and the two following ones consoli- 

 dated. The legs of the female are white, tipped with black, 

 the first pair being tinged with rufous. The palpi are white, the 

 falces and mouth parts dark and the rest of the under surface 

 white, the venter being covered with down. 



The male (dry) has the cephalothorax bright brown, with a 

 wide, white band on each side. Tliere is a good deal of bright 

 red down on the upper surface, in bands below the white 

 bands, and around the eyes. When looked at from in front 

 and a little to the side one sees a bright red band running 

 back from the lateral eyes ; above and below this are white 

 bands, below the white is a dark band, then another white, 

 then another dark. There are some small, black bristles be- 

 hind the lateral eyes, but these are not so distinct as in the 

 female. The abdomen is bright bronzy brown with a silvery 

 slieen ; on each side is a snow-white band, and below this, and 

 contrasting with it, a velvety black band. The first legs, 

 palpi, falces, mouth parts and sternum are dark brown ; the 

 fang is reddish ; the other legs are pale, with black tips. The
