190 GROTE & ROBINSON. 



while the outer limb or third and corresponding sinus only attains the 

 subuiedian nervule. The transverse anterior line and the above-de- 

 scribed inflections are easily lost or overlooked, and are only to be de- 

 tected in fresh and well marked individuals. There is a distinct, black 

 sinuate median shade line, running from costa to internal nervure over 

 the first sinus of the transverse anterior line, and preceded by a faint 

 blackish discal dot. This line is always to be detected; its most pro- 

 minent sinuation is on the discal cell, whence it is 8-shaped. The cos- 

 ta, over the discal cell, is often touched with cinereous. The trans- 

 verse posterior line is preceded by a dark shade, distinctly limited in- 

 wardly ; this limitation appears as a second median shade line, not ex- 

 tending below median nervure, where it joins the upward inflection of 

 the transverse posterior line. The tremulous transverse posterior line 

 above described, is closely followed by a short series of black diffuse 

 dots over the middle of the wing. A very distinct and nearly perpen- 

 dicular subterminal line, always present, consisting of a series of black 

 nervuhir spots obsoletely united. A faint, evenly lunulatc, terminal 

 line rests on external margin. Fringes, discolorous with the wing, 

 griseous. Secondaries, much as in D. erichtea, Iliih., being largely of 

 an obscui'e smoky testaceous cinereous basally. A median paler and 

 wide band, beyond which a deep colored band, diffusely margined in- 

 wardly and distinctly limited externally, where it borders a second 

 very narro.w pale shade; beyond this the narrow terminal space is 

 again of an obscure color. The external margin is edged narrowly by 

 a dark line. Fringes, concolorous with the wings, shaded with testa- 

 ceous at base. 



Beneath, both wings are pale ochreous, with a powdery appearance. 

 All markings have vanished, except two faint darker transverse sub- 

 terminal shades on either wing. Apically the wings tend to be more 

 obscurely shaded.

We have examined a number of 9 specimens of this species which 

 is subject to variation in the distinctness of the ornamentation of the 

 upper surface of the primaries, but in its characters is very distinct 

 from either E. erichtea, Hiibn., or D. erichto, Gue7t6e, its congeners, 

 and with which it associates. Its exclusive specific characters are 

 these: the purely brown super-thoracic and alar coloration; the ab- 

 sence of the distinctly expressed inception of the subterminal line 

 which forms in the other species superposed preapical marks. In its
