Observations. Much as the sexes differ from each other, 

 I cannot doubt their constituting one species, having repeat- 

 edly found them enclosed quietly in the same silk tube, and 

 having always found the males and the females with the char- 

 acters given above. The spots and markings of these spiders 

 are formed by hairs or scales, which have certain metallic 

 reflections. The motions of this spider are slow, and exhibit 

 caution ; it is found usually on trees, and often hibernates 

 under the bark of decaying trunks. The male, remarkable 

 for his enlarged, nearly horizontal cheliceres, is a very bold 

 little fellow, always ready for action, and determined to see 

 all things for himself, raising and turning his head towards 

 the object that approaches him, and usually jumping upon his 

 enemy instead of ingloriously retreating. This species is a 

 common one.

6. Attus multicolor. 



PI, 7, fig. 13. 



Description. Cephalothorax black, with a pale, irregular 

 band each side of the disc ; abdomen metallic green, with a 

 band at base, and a diagonal spot each side, orange, and with 

 eight small white spots ; underneath obscure gray, with inflec- 

 tions of green on the pectus ; feet rufous or pale, varied with 

 piceous, 1. 4. 2. 3. 



Observations. This species is related to A. otiosus and wiys- 

 taceus, but distinct from both by the absence of the tufts of 

 hair on the cephalothorax, and other characters. The palpi 

 are pale yellow, and there is a black band more or less visible 

 on each side of the abdomen. 



Habitat. Alabama. June - August.
