[Illustration: FIGS. 377, 378. Ceratinopsis interpres.--377, head of male. 378, end of palpus of male.] $Ceratinopsis interpres.$--Length about a tenth of an inch. Color bright orange, with a little black around the eyes and the spinnerets. In the female the height of the head equals the length of the mandibles, and in males it is greater. The size of the sexes is about the same. The upper middle eyes are a little larger and farther apart than the front middle pair, and between them is a flattened space covered with stiff black hairs, longer in the male than in the female (fig. 377). The male palpi have the femur as thick as the femur of the first leg and the tibia very short and wide, with a little recurved point on the front edge. They live on low bushes in summer and under leaves in winter. THE EPEIRIDÆ The Epeiridæ are the makers of the familiar round cobwebs. Like the Therididæ and the Linyphiadæ, they live always in their webs or nests back downward or, when in the round web, head downward. The cephalothorax is generally short, as in Therididæ, and low and wide in front, with the eyes near the front edge, the lateral pairs close together and farther from the middle eyes than the latter are from each other. The mandibles are large and strong. The maxillæ are short, often as short as wide, and parallel or a little divergent and rounded at the ends, never pointed or turned inward. The labium is shorter than wide and rounded or slightly pointed at the end. The legs are usually long and, more commonly than in the other cobweb spiders, stout and furnished with spines.
