714 Paradulichia, Hyperioi^sidae, Hyperiopsis 



Q . In close agreement with Dulichia (p. 708), except that uropod 2 

 is quite rudimentaiy, peduncle and rami belüg represented by a Single 

 conically tapering Joint (Fig. 127). Antennae not so elongate as in Dulichia. 

 Maxiila 2 has the inner plate not fringed with setae on the inner margin. —
