groove. The legs are yellow, darker at the ends of the joints. The 

 abdomen is pale, with a dark middle band divided into segments, the 

 anterior one usually darker and the second lighter than the others. 

 The sternum and under side of abdomen are yellow broAvn like the 

 dorsal markings. The epigynum is covered by a slightly convex 

 plate, twice as wide as long, and straight at the posterior edge 

 through which the openings show as dark spots. The males have 

 longer legs and darker coloring than the females. The male palpi 

 have on the patella a long process somewhat like that of L. lohry- 

 giana, but longer and sharper and more cui'ved inward at the tip. 

 Eig. 5. PI. I. 



Found in a grove of spruce trees at Fort Fairfield, Me., Aug., 



1913, and July, 1914, and by Miss E. M. Esterbrook at Stevens- 

 ville Crossing, Newfoundland. Webs like those of L. phrygiana. 



Epeira labyrinthea, Hentz, Bog variety. 



This variety was found on the upper part of Mt. Lincoln, Colo., 

 by F. C. Bowditch in 1877. In 1902, H. C. Britcher found it 

 at Lunksoos, east of Mt. Katahdin, Me. My first acquaintance 

 with it was in August, 1913, on the bog at Crystal, Me., where I 

 found an old female with nests and eggs. The next year, July, 



1914, I visited the same bog earlier in the season, and found both 

 sexes. On this bog these spiders live in the stiff narrow-leaved 

 grass, Scirpus caespitosus, growing about a foot high over the 

 open parts of the bog. In July their nests are small, attached to 

 two or three grass leaves drawn together, and differing from the 

 typical labyrinthea nest only in having around it a smaller 

 "labyrinth." At this time males have nests like the females. In 

 August, after the females have laid eggs, the nests are enlarged 

 and improved, and hang down from the bunch of grass leaves, held 

 in place by strong threads extending in several directions to other 

 leaves, often three or four inches distant. In the typical bush nest 

 of labyrinthea (see photograph in Comstock's Spider Book, pages 

 464-465), the egg cocoons are attached outside the nest, sometimes 

 partly united with it, but in the bog variety the cocoons are 

 enclosed in the upper part of the nest, forming a cone of light 

 brown silk on the outside of which are scattered lumps composed 

 of the remains of insects and sometimes leaves from neighboring 

 plants. 



This A^ariety differs from the usual labyrinthea in its deeper 

 color and greater contrasts between the black and white markings.
