Female : Total length, 12.5 mm. ; cephalothorax, 5 mm. long by 5 nnn. wide ; aljdomen, 

 8 mm. long by 6.5 mm. wide. The general color is grayish brown, which in gome speci- 

 mens is deepened into iron gray upon the abdomen, cephalothorax, and terminal joints of 

 legs. The cephalothorax and abdomen are usually uniform in color. 



Cephalothora.y : A rounded oval, truncated at the base ; the median fosse is a deep 

 lateral pit placed back of the middle point, which is the highest ; the sides of the corselet 

 are rather steeply sloped, the head depressed, the caput inclined from its insertion to the 

 eye space ; color glossy black brown, covered sparsely along the sides with gray hairs, which 

 form a thicker band at the margin, and are spread out more thickly along the sides of the 

 caput forming heavy eyebi'ows, and covering the clypeus. Sternum shield shaped, longer 

 than wide, but of nearly equal width to the third cox;e ; glossy l)lack, covered particularly 

 at the sides with gray hair ; labium wider than long, the tip triangular ; the maxilUe as 

 wide as, or wider than long, inclined towards each other, rounded on the sides, and, like the 

 labium, dark glossy brown, light yellow at tips. 



Eyes : The ocular quad upon a rounded prominence most decided in front, whicli is 

 decidedly wider than the rear, and about as wide as the sides. MF are separated by about 

 two diameters, and are larger than MR, which are separated by more than one diameter. 

 Side eyes upon tubercles, separated by about the radius of SR, which is slightly smaller 

 than SF, and situated almost upon a line with it ui:ion the side face, thus, as in the case of 



* Strictly adhered t-o, the law of priority would give this name to the species, as it appears first in 

 order of paging in Clerck's book. This seems to have led Koch and Blackwall, as below, to adopt the 

 name Epeira sericata, the latter, however, subsequently abandoning that for the more generally accepted 

 one. As the change would not affect the credit due to the first author, and would cause much confusion, 

 the better known title is here retained.
