Agrotis haesitans Wlk. — Placed by Hampson in Epipsilia. According 
to a sketch of the right clasper of the type, kindly made by Mr. Tams, the 
genitalia are typically Agrotid. 
Epipsilia pi/rsoaramma Dyar. — 1916, Proc. U. S. N. M. } LI, 9; B. 
and B., 1924, Cont. V, 115. 
Lycophotia triphaenoides Dyar. ( Rhynchagrotis orbipunda B. and McD.) 
— Benjamin placed this in Agrotis between larga Sm. and subporphyria 
Wlk. 
Rhizagrotis epipsilioides B. and B. — -1926, Pan. Pac. Ent., II, 106. 
Agrotis scaramangoides B. and B. — -1926, Pan. Pac. Ent., II, 107. 
Agrotis tedoides Corti. — -1926, Rep. 3rd Int. Ent. Cong. II, 132. 
Possibly a synonym of scropulana Morr., but the species is too insufficiently 
diagnosed to determine accurately.

(8) Harpe entirely lacking Heptagrotis gen. nov. 
Harpe present 9 
(9) Harpe bifid, one strong arm curved downward and projecting over a hollowed 
out portion of the ventral margin of clasper, the other arm weak, oblique, 
and slightly projecting over costa Hemieuxoa gen. nov. 
Harpe simple 10 
(10) Harpe a slightly recurved corneous hook, attached to the apex of the sacculus 
and lying mostly in a groove of the clasper subparallel to sides of same, 
rarely oblique or projecting over dorsal edge, but if so never excurved. ... 11 
Harpe excurved, attached, more or less at right angles to the plane of the 
clasper, either directly to the apical portion of sacculus by a curved rod of 
chitin or to a foot-like base a short distance above same 29
