I am unwilling to see in this species a variety of E. lugubris, as Dr 

 Herrich-Shaeffer is disposed to regard it. The specimens are constant 

 in the differences I have noted and seem to me sufficiently specifically 

 distinct.

 The excavations of the anterior wings are modified from either of 

 the above species, while more nearly approaching E. Oamertus. On 

 the posterior wings the excavations before anal angle are diflFerent, the 

 tegument at the submedian nervure being more produced so as to form 

 very plainly a double excavation between the medio-posterior nervule 

 and the internal nervure. 



The coloration is very dark brown, while the discal dot is not black 

 but pale brown on anterior wings. On posterior pair in the male 

 there is a small patch of pale yellowish hair at extreme base of the 

 wing along internal margin ; in the female this patch is much larger, 

 spreading nearer to anal angle. The whole body is somewhat slenderer 

 than in the preceding species. Two specimens % and 9 . Exp. % 2.40,

Professor Burmeister's description differs as to the ornamentation of 

 the posterior wings from both Cramer's figure and my specimens, which 

 agree together. It is not improbable that his specimens are errone- 

 ously referred to the present species. His description of the internal 

 margin of the posterior wings does not correspond, and if by "Auf 

 der Unterseite der Oberfliigel ist ein weisser Punkt" he alludes to that 

 on the costa before the apex, the species does not differ in this respect 

 from the preceding two. If, however, a discal spot is meant, it is cer- 

 tainly wanting in my specimens of E. danum, where there is in the 

 female a mere trace of a paler shade on the discal cross-vein. Dr. 

 Clemens does not mention this species, probably since Mr. Walker 

 merely gives " Surinam" as the habitat. I have expressed my opinion 

 that perhaps under E. Iwjubris " Var y. Nigro-fusca ; alseposticse striga
