Ohservations. The spots and bands in this, as well as in 

 most of the other species of this sub-genus, are produced by 

 scales or hairs which are quite deciduous, and hence there are 

 many varieties of markings. This spider moves with the 

 rapidity of lightning.

10. Herpyllus variegatus. 

 PI. 11, fig. 12. 



Description. Cephalothorax rufous ; abdomen blackish, with 

 three whitish bands, the middle one as an inverted ± ; feet, 

 varied with piceous and rufous. 



Observations. This spider, drawn fi'om a specimen collected 

 by Prof. Peck of Massachusetts, was immersed in spirits ten or 

 twelve years at least, before it was painted. The colors may 

 not be correctly represented in consequence of that. A speci- 

 men was found in North Carolina, and also one in Kentucky, 

 in a silk tube, which had only two bands on the abdomen, and 

 the external eyes of which were placed nearer together. 

 These will probably be found to belong to another species.
