Of the genera included in the group Delenece the members of this genus come nearest to Heteropoda Latr., with which they were included by L. Koch. Neither the cephalothorax nor abdomen show any signs of compression ; the coloration and patterns are often vividly bright and varied, and the patterns of the female vulva are of rather diversified form, though roughly a sunken area, more or less divided longitudinally by a wedge-shaped ridge, enclosed in a cliitinous frame. The male palps, however, in all the species of which I have been able to obtain specimens, are of the spiral conductor and flagellum type, more or less elaborated and varying from two or three spirals in If. calligaster Thor, and If. diana L. K., to nine or ten in If. salacius L. K. The cephalothorax is generally high, the highest point of the curve being between the eye-space and middle of cephalothorax, thence sloping posteriorly, and in this differs from Heteropoda Latr., where L. Koch placed the species. Owing, however, to the an°le at which the cephalothorax is often set on to the abdomen, the front part appeal's more prominent than it really is with respect to the plane of its legs. Besides the palpal difference from the type species of Sparassus, they differ in having legs in order 2 1 4 3, instead of 4th longer Pediana E. Sim. (2) Neosparassus, nov. gen. (1) Zachria.
