distad. Uncus setigerous, stout, narrowing acutely distad and tipped 

 with a short sharp curved tooth; gnathos naked, slender, exceeding the 

 uncus, at tip widening and the margins upturned forming a pocket into 

 which the tip of uncus fits when closed. Harpes (Fig. II, 5) broad 

 at base, the costa of the harpes proper free but greatl}^ reduced to chit- 

 inized angular lobe extending at right angles to the base of the cucullus 

 which is a broad rounded, lightly chitinized process, hairy within and 

 separated from the sacculus by a narrow chitinized carina. Sacculus 

 broad and almost rectangular, slightly concave, sparingly setigerous on 

 both margins with a portion of the inner margin thickened and inturned 

 and terminating in a small rounded lobe. Vinculum a broad sub- 

 triangular, weakly chitinized area supporting the sacculi. Aedoeagus 

 (Fig. II, 4) subconical, smaller and rounded at the base, flaring 

 somewhat at the open end, very feebly chitinized, bearing inside about 

 midway a small acute chitinous spine with a broad flat base, and just 

 within the open end and projecting far' beyond a huge, heavily chitinized 

 curved, flattened spine longitudinally carinate at the base and covered 

 with minute acute points inclined toward the tip, this spine or comutus 

 equalling in length the aedoeagus proper. The anellus is a mere mem- 

 brane attached to the aedoeagus ventrad.
