Figures 24-40. — Female antennae of Stilobezzia species (only antennomeres VI-XI 

 and XV shown). 24-34. Subgenus Neostilobezzia: 24, insolita; 25, xanthogaster; 26, miripes; 

 27, magnitheca; 28, parvitheca (XV omitted); 29, crassivenosa; 30, parvaeungulae; 31, 

 constans; 32, speculae; 33, subnebulosa; 34, venefica. 35-40. Subgenus Eukraiohelea: 35, 

 punctifemorata; 36, fuse iter ga; 37, minuta; 38, clarifemorata; 39, fuse ipes; 40, brevicostalis. 



Wing: Rather long (in female, well over twice the breadth) ; micro- 

 trichia distinct throughout, usually well sclerotized adding to the 

 wing shading; macro trichia absent on wing surface (subgenera 

 Eukraiohelea and Stilobezzia) or present at wingtip and variably in 

 extent toward base of wing {Neostilobezzia) ; radius usually with a seta 

 near basal arculus and often with setae scattered variably along its 

 length and on its branches; venation strong on radius and its branches, 

 on base of media and r-m crossvein, but weak posteriorly. Inter- 

 calary fork distinct only in exceptional species; costa extending to 

 two-thirds or more of wing length as a rule, never exceeding tip of 

 vein R 4+5 ; first radial cell (IRC) may be totally absent, poorly 

 formed, or quite spacious but only a third or less of the length of the 

 second radial cell (2RC), which is long and spacious; stem M dis- 

 tinctly petiolate, long, subequal to, or shorter than r-m crossvein,
