Epeira globosa or triaranea.—Length about a quarter of an inch, the male a third smaller. The abdomen is round and as wide as long, and in the female large for the size of the spider. The front half of the abdomen is nearly covered by four white, yellow, or pink spots, partly united into a rectangular figure surrounded by an irregular black line [(fig. 407)]. The hinder half has three or four pairs of black spots. The general color is light brownish yellow. The cephalothorax has a fine middle line from the eyes to the dorsal groove and indistinct dark marks at the sides of the head. The first and second legs have slightly darker rings at the end and middle of each joint, the third and fourth pairs at the ends of the joints only. The male is marked like the female and has the tibia of the second legs slightly curved and thickened with large spines on the inner side.

This spider makes a very large tent, out of which a strong thread runs to the center of the round web [(fig. 406)]. From the tent a loose and irregular web extends downward, sometimes covering half of the round web [(fig. 406)]. Opposite the thread leading to the tent, a segment of the round web is left open or partly open without any sticky threads.

Epeira labyrinthea.—This spider makes a large irregular web in which is a tent connected by a thread with the small round web below, much as in Epeira globosa. The female is a fifth of an inch long. The abdomen is oval and not unusually large, as it is in globosa [(fig. 408)]. The cephalothorax is long, dark brown in the middle and lighter at the sides, and almost white in front around and behind the eyes. The legs are white, with narrow dark brown rings at the ends of the joints and wider yellow rings on patella and femur of the first and second pairs. The abdomen is marked with four long white spots in front and a dark brown middle band behind. At the sides the abdomen is light brown or yellow. On the under side the ends of the mandibles and the maxillæ are black. The sternum is black, with a white middle stripe. The abdomen has a short middle white stripe surrounded by a large dark spot, and there are several yellow spots along the sides and around the spinnerets.
