Agrotinae. The prothoracic leg extends cephalad to the eye-piece, but 

 there is never a long point extending cephalad between the antennae 

 and the sculptured eye-piece. The genera of Hadeninae may be sep- 

 arated by the following table : 



a. Dorsum of movable abdominal segments with a row of deep pits along 

 the cephalic margin. 



b. Caudal end of body with a very short cremaster ending in two 

 straight sharp setae with four slender hooked setae at the prox- 

 imal end, the hooked setae about half the length of the straight 



ones CirpJiis Walker. 



bb. Cremaster very short, with a long straight seta inserted in each 

 caudo-lateral angle; hooked setae never present. 



Monima Hiibner. 

 aa. Dorsum of movable abdominal segments never with a row of deep 

 pits along the cephalic margin. 

 b. Mesothoracic leg never reaching cephalad to the eye-pieces; pro- 

 thoracic femora always exposed, 

 c. Caudal end of the abdomen with four closely approximated spines 



of the same size and shape RJiodopJiora Guenee. 



cc. Caudal end of body with only two spines. 



d. Spiracles noticeably modified, usually with a prominent de- 

 pression near their caudal margin ; spiracular opening di- 

 rected somewhat caudad; cephalic third of the movable 

 abdominal segments usually slightly elevated and densely 

 punctate, 

 e. Cremaster slender, pointed, spines closely approximated ; 

 abdominal spiracles with a darker, elevated, crescent- 

 shaped area almost surrounding the spiracle and with a 

 deep cavity larger than the spiracle directly caudad of it ; 



mesothoracic spiracles not modified Meliana Curtis. 



ee. Cremaster short, blunt; area around each abdominal spir- 

 acle slightly elevated and darker in color, a prominent cav- 

 ity caudad of the spiracle with a chitinized ridge along the 

 caudal margin of the spiracle; mesothoracic spiracles also 

 modified, the opening extending half the distance between 

 the antennae and the meson, 

 f . Chitinized ridge along the caudal margin of the abdominal 

 spiracles distinctly serrate ; clypeal region not promi- 

 nently elevated and without deeply impressed lines. 



LapJiygma Guenee. 

 ff . Chitinized ridge along the caudal margin of the abdominal 

 spiracles not distinctly serrate; clypeal region promi- 

 nently elevated and with deeply impressed lines. 



Prodenia Guenee.
