surface ; cephalic end of body not elevated between the an- 

 tennae ; short eremaster sometimes present. 



Apatclodes Packard, 

 cc. Abdominal segments 2-7 never with flanged plates; appen- 

 dages distinctly elevated ; cephalic end of body elevated be- 

 tween the antennae ; eremaster never present. 



Harpyia Ochsenheimer. 

 aa. Maxillae ahvays more than one third the length of the wings; never 

 with both prothoracic and mesothoracic legs meeting on the meson ; 

 abdomen usually rather coarsely punctate, 

 b. Maxillae from one half to three fifths the length of the wings; 

 mesothoracic legs meeting on the meson caudad of the maxillae ; 

 appendages roughened with deep indeterminate striations ; ab- 

 dominal segments coarsely punctate ; a distinct, deep furrow on 

 the dorsum between the ninth and tenth abdominal segments; 

 eremaster short, bifurcate, each half with several short spiny 



processes, usually directed laterad Batana Walker. 



bb. Maxillae more than three fifths the length of the wings ; neither 

 prothoracic nor mesothoracic legs meeting on the meson caudad 

 of the maxillae ; appendages usually with shallow indetermi- 

 nate striations; a distinct furrow never present on the dorsum 

 between the ninth and tenth al)dominal segments ; eremaster not 

 as described above, 

 c. Entire body surface with coarse, deep punctures ; cephalic mar- 

 gin of the movable abdominal segments with large lunate 

 punctures and a distinct ridge with a row of large, very dis- 

 tinct punctures just caudad of the ridge; eremaster short, 

 rugose, slightly bifurcate, bearing six long hooked setae ; meso- 

 thorax never with a deeply pitted caudal margin. 



Synimerisfa Hlibner. 

 cc. Body usually punctate on the abdomen, but not on the appen- 

 dages; movable abdominal segments sometimes with a slight 

 ridge along the cephalic margin, but never with a distinct 

 row of large punctures caudad of the ridge ; eremaster bifur- 

 cate, but never with hooked setae ; mesothorax with a row of 

 deep pits along its caudal margin with smooth quadrangular 

 areas between, and partly covering them. 

 d. First abdominal segment with a small tubercle on each side of 

 the meson at the cephalic margin of the segment ; entire dor- 

 sal surface of the tenth segment distinctly elevated and very 

 rugose ; points of the eremaster divergent. 



Hyparpax Hlibner. 



dd. First abdominal segment without tubercles ; entire dorsal 



surface of the tenth segment not elevated and rugose. 



e. Wings always touching on the meson ; maxillae never as 



long as the wings ; cephalic end of body sometimes with 



two sharp, heavily chitinized spinous projections. 



Scliizura Doubleday.
