$Dictyna frondea.$--This resembles _volupis_ and is likely to be mistaken for it. It is a little smaller, not over a tenth of an inch long, and there is less difference between the sexes. The legs are pale, and the cephalothorax light brown, lighter on the head. The abdomen is gray at the sides, not as red as in _volupis_, and the middle light stripe is narrower and not as bright yellow (fig. 479). The sternum and under side of the abdomen are gray, as dark as the upper part and sides, while in _volupis_ they are generally lighter. The males have the cephalothorax larger, and that and the legs a little brighter colored than in the female, and the abdomen darker. The mandibles are not as long as in the male _volupis_, and the ends of the male palpi are much smaller and the tibia longer and straighter than in _volupis_ (fig. 481). [Illustration: FIGS. 482, 483. Dictyna cruciata.--482, female enlarged eight times. 483, cephalothorax and palpi.] $Dictyna cruciata.$--About a tenth of an inch long, with the abdomen large and oval, as in _muraria_. The cephalothorax is light brown above and below, and the legs the same color, but still lighter. The abdomen is gray beneath and at the sides, and silvery white on the back, sometimes over the whole upper surface, but oftener in a stripe widened in the middle so as to form a white cross on a gray ground (fig. 482). The males are darker colored, with the light spot on the abdomen smaller. The male palpi are short and slender, the ends large and rounded and carried close to the head (fig. 483).
