Male genitalia. — Harpe broad and short (when compared with 

 those of other members of the genus) , clothed over most of the sur- 

 face with fine hairs; cucullus rounded (in one specimen from Cali- 

 fornia the cucullus is long and slender) ; clasper long and slender, 

 reaching to, or slightly beyond, the costa; occasionally the clasper 

 is slightly hooked at the distal end. Anellus an oblong-oval plate; 

 posterior edge nearly straight with shallow median cleft; lateral lobes 

 well developed. Vinculum rounded, with dorsoanterior process. 

 Aedeagus slender, tapering distally to a point just past the middle, 

 then becoming larger and finally terminating in a sharp point. At 

 the base of the aedeagus is a bifid arm by which it articulates with 

 the anellus. Transtilla a broad sclerotized band, with large, hairy, 

 lateral lobes. Gnathos a slender spined cone. Socii large hairy 

 flaps. 



Female genitalia. — Genital plate broad. Ostium small, at ex- 

 treme anterior margin of plate. Ductus bursae long, membranous;

 oval plate.
