in the same plane, being bent upwards beyond point of origin and then 
recurved, almost reaching apex of clasper. Uncus short, pointed. Clavus 
very minute. Juxta a thin plate. Aedoeagus with rectangular apex, the 
lateral walls slightly thickened with chitinous plates, no armature. 
The genus Amphitrota was erected for our North American species 
with abdominal foveae in the female sex; as, however, the male genitalia 
of the two included species, clandestina Harr. ( unicolor Wlk.) and havilae 
Grt., are very similar to those of ravida, the genotype of Spaelotis Bdv., 
this name is preferred. The genital organs are quite unique and show no 
close affinities to those of any other species; on general characters, how- 
ever, the writer inclines to group the genus with the typical Agrotids. It 
might be pointed out that the name clandestina Harr. (1841) has priority 
over unicolor Wlk. (1856) and that the present listing, following Hampson’s 
error, should be altered. 
Choephora Grt. 
1868, Trans. Am. Ent. Soc. II, 199 (type, Jungorum Grt.). 
Eyes naked. Palpi upturned, wfith third joint somewhat porrect; 
both joints heavily fringed below with long hair. Front smooth. Male 
antenme strongly bipectinate. Tibiae all spined; fore tibia longer than 
first tarsal joint, with a row of moderately stout spines on each side, neither 
of which extends completely to base; on outer side a fringe of long hair in 
basal portion. Mid tarsi without fourth row of spines. Thoracic vestiture 
very rough and hairy. Wings broadly triangular.
