 characters of the aedeagus. Harpe moderately broad and clothed with 

 fine hairs, especially in apical half; clasper divided, one arm parallel- 

 ing sacculus, the other transverse, arising well before middle of harpe, 

 reaching nearly to costa, and without lateral process ; sacculus heavily 

 sclerotized; anellus a sclerotized plate with median trough on which 

 the aedeagus articulates ; lateral hairy lobes present. Aedeagus stout, 

 only slightly curved ; cornuti numerous, strong, in an elongate patch. 

 Vinculum rounded, broad. Transtilla a narrow sclerotized band with 

 lateral hairy lobes. Gnathos an oval spined knob. Socii fleshy hairy 

 lobes. Apex of tegumen with median cleft. 



Female genitalia. — Ostium moderately large, located near anterior

 anterior to ostium. Ductus bursae membranous except for two sclero-
