Genotype. — Mulona lapidaria Walker. Monobasic. 



Labial palpus, antenna, and venation as described on page 221. 



Male genitalia (pi. 10, figs. 2-6) with uncus slender, curved and 

 hooklike in some species and broad and hoodlike in others, terminating 

 in a short constricted point in all species, this point usually blunt; 

 gnathos weakly sclerotized and divided, forming two broad short 

 lobes; anellus bifurcate with stongly sclerotized arms and these arms 

 nearly as long or longer than harpes; trans tilla present and wholly 

 or partially fused; vinculum triangular to nearly round; aedeagus 

 thick throughout, distally broad and blunt and armed with various 

 broad, sometimes dentate lobes; ductus ejaculatorius entering anterior 

 end of aedeagus; vesica with numerous scobinations; harpe with an 

 apical lobe or arm (the cuiller) and with a clavus and with a third 

 arm from base of costa (except in M. schausi where apex of harpe is 

 a broad rounded lobe and clavus is greatly reduced). 



Female genitalia (pi. 11, figs. 8-11) with ductus bursa nearly flat 

 and only partially sclerotized, with two separate sclerotized latero- 

 ventral plates near ostium bursae or with ductus bursae flat and 

 almost entirely sclerotized, triangular or subtriangular; bursa copu-
