rank by some authors, and while the species included here differ from 

 the typical noctuid in many respects, still no structural characters 

 could be found to warrant their separation from the Noctuidae. The 

 entire body surface is very rough and spinose, while the cremaster 

 is short, broad, and decidedly flattened, with its caudo-lateral an- 

 gles produced into rounded lobes, and with the caudal margin often 

 crenulate. There are sometimes short straight setae present along 

 the caudal margin. The antennae, mesothoracic legs, and maxillae 

 usually reach the caudal margin of the wings, or approach it very 

 closely. Each prothoracic leg extends cephalad to the eye-pieces. The 

 epicranial suture is always present. The labial palpi are always visi- 

 ble, but the femora of the prothoracic legs are concealed except in 

 occasional specimens. The abdominal spiracles are somewhat elevated 

 and are surrounded by a heavy, dark, chitinized border. The open- 

 ings appear to be fringed with fine setae. The genera of this sub- 

 family may be separated as follows : 



a. Antennae always reaching the caudal margin of the wings; the row 



of spines along the caudal margin of the abdominal segments not 



larger than the spines of the segment; ninth abdominal segment 



never with scattered spines larger than those of the other segments. 



b. Dorsum of the abdominal segments rugose and densely spinose on 



the first nine segments Euthisanotia Hiibner. 



bb. Dorsum of abdominal segments rugose and moderately spinose 

 on the first seven segments; the eighth and ninth segments 



roughened, but with very few spines Alypia Hiibner. 



aa. Antennae never reaching the caudal margin of the wings; the row 

 of spines along the caudal margin of the abdominal segments 

 larger than those of the segment; ninth abdominal segment with 

 scattered spines larger than those of the other segments.

Subfamily Acronyctinae 



The subfamily Acronyctinae as typified by the genus Acronycta 

 has little to distinguish it from other subfamilies except that the cre- 

 master is short and usually mound-like and the setae are always of 

 the same size and length. With this genus there are here included 

 several others, which probably do not form a natural group, though 

 all possess cremastral setae of the same size and length and in all the
