Spintharus flavidus.—A sixth to a quarter of an inch long. The cephalothorax is nearly circular, and the head small and narrow like that of Argyrodes, with the hinder middle eyes very far apart. The abdomen is widest across the front third, where it is two thirds as wide as it is long, and from here it tapers to a blunt point over the spinnerets [(fig. 302)]. On the back the abdomen is flat and marked with white stripes each side, and between them a large pattern in black and red, lighter toward the middle, where there are two or three pairs of white spots. The legs are slender like those of Argyrodes, the first and fourth pairs the same length and twice as long as the second pair. The tibiæ of the first and second legs are bright orange color, and the rest, like the cephalothorax, pale yellow. The male has longer legs and more slender abdomen. They live on low plants, and the web is unknown. They have been found from Massachusetts to Alabama.

Euryopis funebris.—A little dark-colored spider, with a flat abdomen pointed behind and bordered with a silver-white stripe. It is almost an eighth of an inch long. The cephalothorax is small and as wide as it is long, with the sides rounded. The head is half as wide as the thorax, a little raised and extended forward over the mandibles [(fig. 303)]. The front middle eyes are largest and are farther apart and farther forward than the others. The abdomen is flat and nearly as wide in the middle as it is long, and tapers to a point behind. The general color is black or dark gray. The cephalothorax is yellowish under the abdomen and black in front. The abdomen has a bright silvery stripe around the hinder half, and inside this the color is black, broken by light spots in the middle. The legs and palpi are light yellow, with dark rings on the ends of the joints. The fourth legs are longest. It is shaken from bushes in summer, or from dead leaves on the ground in winter, and its web is unknown. It is found from the White Mountains to Alabama.

Theridula sphærula.—This is a very distinct and easily recognized species, although it is less than a tenth of an inch long [(fig. 304)]. The cephalothorax is yellow, with a wide black stripe in the middle. The abdomen is high and round and wider than it is long; it is yellowish gray, with a greenish white spot in the middle and a black spot on a slight elevation at each side. There is also a black spot around the spinnerets. The legs are light yellow. In the male the light parts of the cephalothorax and legs are orange color, and the markings of the abdomen less distinct than in the female. It lives on bushes all over the country.
