AMERICAN LEPIDOPTERA. 199 



transverse posterior line is incepted above the reniform, runs out- 

 wardly straiglitly along the costal region, thence downwardly over the 

 nervules, bending inwardly beneath the reniform spot. It is gemi- 

 nate, faint, the lines enclosing a paler space and interspaceally lunulate. 

 Subterminal line pale, preceded by a dark shade, forming the usual 

 M-shaped mark at the middle, the points of the M attaining the ex- 

 ternal margin. The dark shading is sometimes tinged with olivaceous 

 before the internal angle as is the inferior shading of the longitudinal 

 streak connecting the median lines. The terminal space is blackish 

 brown and black interspaeeal marks precede the terminal line. The 

 fringes are uneven ; the external margin of the wing retires inwardly 

 before internal angle. 



Beneath pale. The wings terminally and along costal edges are 

 covered with powdery squamation with intermixed dark scales bringing 

 the nervules into relief. The primaries show three ante-apical white 

 dots and the white subterminal shade line emanates from a fourth and 

 larger dot just before the apex, these latter at times hardly diseerna- 

 ble. Faint discal dots; sometimes traces of dark median lines can 

 be seen on both wings. Above the secondaries are smoky black- 

 ish, paler towards the base, without discernable discal mark or lines. 



Expanse, 35 — 39 mil. Length of body, 15 — 17 mil. 



Habitat — Atlantic District. The imago flies in July and August. 



Allied to Hadena distincta and H. xylinoides, but readily distin- 

 guished by the details of ornamentation and general color, while quite 

 similarly sized. The antennae are inipectinate. 



CHOEPHOKA, E.g. 



Antennae rather short, strongly bipectinate. Maxillae weak. La- 

 bial palpi thickly scaled, hardly exceeding the front, apical joint con- 

 cealed. Caputal and thoracic squamation long and thick, tufted be- 

 hind the " coll'ar" and the scales are raised on the vertex. Legs mode- 

 rately long; anterior tibiae with an unequal pair of spurs at the ex- 

 tremity of the joint; hind tibiae with two unequal pair of spurs, one 

 at the middle and one at the extremity of the joint. Abdomen 

 smoothly and closely scaled, exceeding the secondaries. 



Wings entire and ample. Costal edge of primaries straight and 

 thickened ; apices acuminate. Neuration : Costal nervure simple, 

 straight ; fii'st s. c. nervule thrown off on the upper side of the ner- 

 vure at basal third and adjoining the costa at a point beyond the ex- 

 tremity of the costal nervure ; second s. c. nervule thrown off from 

 the upper side of the nervure, its base forming the upper side of an
