spots. Toward the front, tlie folium is a little reddish and at the 

 sides yello'.v. The legs are yellowish, nearly covered by irregular 

 dark rings and spots. The sternum is bright yellow in the middle 

 and black around the edge. The abdomen is black beneath. Another 

 specimen is much paler with the legs almost white, and the markings 

 of the back broken up into a few gray spots. 



Both specimens are females.

Microepeira, new. 



This genus is distinguished by its small size and large epigynum 

 and palpal organs, and also by its web, which according to McCook 

 has the rays united in groups of three or four, and is drawn into a 

 conical shape by a thread attached to the center,

This spider is only 2"'"' long. The cephalothorax is gray without 

 any distinct markings, except black rings round the eyes and slightly 

 darker stripes on the thorax. The legs are yellowish white, darker 

 at the ends of the joints. The abdomen is nearly spherical. The 

 back is white with brown markings. The folium is not well defined 

 but is plainer behind than in front, and consists of two rows of irreg- 

 ular brown spots, the pair on the first segment being separate from 

 the others. In the middle is an irregular brown line. The sternum 

 has a light stripe in the middle and is brown at the sides. The 

 under side of the abdomen is dark. The epigynum is very large and 

 triangular seen from behind. The opening is round and partly cov- 

 ered by a thin plate that extends across the abdomen just behind the 

 epigynum. 



The male differs but little in size and color from the female. The 

 palpal organs are very large. The tube is black and long, sup}>orted 

 by a hard brown appendage. Fig. 1. 



I have this species from the White Mountains, N. H., and from 

 Waverly near Boston, Mass.; and from H. C. McCook from Phila- 

 delphia, Pa. 



I have never noticed the web, but according to Mr. McCook (Proc. 

 Phil. Acad. Nat. Sci., 1881) the rays instead of all pointing to one 

 center are united in groups of three or four, each group connected 

 with the center by a single thread. The web is drawn into the shape 

 of an inverted umbrella by a thread extending from the center to a
