$Icius elegans.$--A little bronze green spider, from a sixth to a quarter of an inch long. The cephalothorax is two-thirds as wide as long, with the sides nearly straight and parallel in the female but widened behind the middle in the male. The abdomen of the female is oval and nearly twice as long as wide. The color is bronze green, changing in some lights to copper red. The legs are yellow, with longitudinal dark stripes, except the front femora, which are dark brown. The males are much more brightly colored. The legs are orange, darker toward the ends, with fine dark longitudinal stripes. The ends of the front tibiæ are dark brown and have long brown hairs on the inner and upper side. The palpi are orange, darker toward the end. The sides and hinder part of the cephalothorax are orange, and there is a white line over the coxæ. The upper part of the cephalothorax and abdomen is covered with greenish yellow scales. On the front of the head are two tufts of long hairs, yellow mixed with black, pointing forward and a little inward between the middle and lateral eyes. On the hinder end of the abdomen is an iridescent purple spot. The abdomen is green on the under side, and the sternum and coxæ are orange. In alcohol all the colors become dull. The mandibles are slender, and the claw short and strongly curved inward toward the point. In the male the mandibles are a little longer and hollowed a little on the inner side. The male has the first pair of legs much longer and larger than the others. In the female the fourth legs are longest. [Illustration: FIG. 152. Mævia vittata.--Female enlarged six times.] $Mævia vittata.$--This is a brightly colored spider about a third of an inch long and with unusually long legs for this family,--the fourth pair longest in the females and the first and fourth of equal length in the males. The female (fig. 152) has the legs and palpi translucent yellow or greenish white. They are marked with indistinct light gray rings and black spots at the base of the hairs and spines. The cephalothorax is dark brown between the eyes and translucent like the legs in the thoracic part. There is a fine black line in the middle and one on each side and a few gray marks radiating from the dorsal groove. The whole top of the cephalothorax is covered with greenish yellow scales mixed with gray hairs. The eyes are black, and sometimes there is a red stripe under the eyes at the sides. The abdomen is covered with scales which in the middle and at the sides are gray and mixed with black hairs. There are two longitudinal bands of light red and indistinct angular marks of the same color in the middle of the hinder half. On the under side the colors are light gray and yellow, with spots of darker gray on the abdomen. [Illustration: FIGS. 153, 154.
