MAIOIDEA. 91 



medial line, is somewhat raised longitudinally, and bears minute tuber- 

 cles, which give origin to tufts of setae. The part of the front below 

 the outer antennas is broader than long, and the breadth by the 

 second of the lateral angles is greatest. The female abdomen, ex- 

 cluding the first two joints, is orbicular and ciliate. The outer antennas, 

 as exposed in a front view, have the first of the two moveable basal 

 joints oblong and stout and densely hirsute on either side, the second 

 about half shorter and slender. The flagellum is five or seven jointed. 

 Anterior legs slender; others stout and somewhat compressed. The 

 hand is slender, tapering somewhat from the base, and the fingers are 

 mostly contiguous, or touch only along outer half.

SUBFAMILY CHORINEO3. 

 GENUS CHORILIA, Dana. 



PisEe Chorinoque affinis. Carapax anymtus, triangulate ovatus, gib- 

 bosus, paulo annatus, rostro lonyo, furcato, cornubus gracilibus. Oculi 

 in orbitis retractiles. Antennae externce sub rostro latentes, articulo 

 pi'imo angusto, apice externo acuto. Orbita infra interrupts, supra 

 angustd unifissa, spind prceorbitali acutd. Pedes \mi 2di# breviores, 

 8 postici similes, 2di Stiis non multo longiores. 



This genus differs from Pisa in having the outer antennas concealed, 

 and from Chorinus, in the second feet not being much longer than the 

 third, and the first shorter than the second.
