Coloration: Ceplialo thorax, clypeus, abdomen and venter black, thinly- 

 covered with short yellow hairs; on the abdomen the thickening of 

 these hairs forms two yellow spots on the anterior part, and three 

 transverse yellow bands. Falces, mouthiDarts, sternum and coxse 

 light brown. Palpi and legs brown with some short yellow hairs. 



The following remarks are from a letter written by Col. John J, Young, 

 of Allegheny, Pa., to whom we are indebted for this species: 



" These spiders are found at this season (November) under the bark of 

 trees, usually hickory and sycamore. You will note that the general color 

 of the spider corresponds with the rusty brown of the under side of the 

 bark of the shag-bark hickory when first pulled off. In that hibernating 

 locality it covers itself with a thin bluish envelope. The spider is so nearly 

 of the bark color, and so small that we would often overlook the speck in 

 the centre of the envelope, supposing it to be merely the empty tube or 

 ceU of some young spider." 

 Habitat: Pennsylvania.

Cephalothorax not high, convex, a little contracted behind dorsal eyes, 

 sides nearly vertical in front, rounded behind; cephalic part much 

 inclined; thoracic part sloping from just behind dorsal eyes. Ocular 

 area occupying more than one-half cephalothorax, less than one-fifth
