on the posterior wings the median blackish shade lines are especially 

 very distinct. On the upper surface, the anterior wings show a series of 

 black dots in the interspaces, increasing in size towards internal angle, 

 absent in the foregoing species; the internal margin of anterior wings 

 is straighter, and the external margin of posterior wings more exca- 

 vate before anal angle, than in E. Merianse.

Erinnyis melanoholica, n. s. (Plate 2, fig. 4, % .) 



Anterior wings dark cinereous in the female, much shaded with 

 blackish-brown in the male, traversed by many confused, inconspicu- 

 ous lines. No paler patches at apex and on internal margin, are per- 

 ceptible, while the transverse lines are more distinct terminally, and 

 especially before internal angle, where they are margined with pale 

 cinereous, showing the ordinary ornamentation of the genus in this 

 respect; external margin denticulate. 



Posterior wings, reddish-ferruginous, with rather narrow blackish 

 borders, the nervules within, touched with blackish dots, much as in 

 the two preceding species ; external margin more excavate before anal 

 ansile than in E. Merianse. much as in E. amotrus, which E. melan- 

 cholica more nearly approaches. 



Under surfiice brownish, with ferruginous scales on the disc of ante- 

 rior pair ; posterior wings whitish at base, below costal region, along 

 internal mai-gin, reddish over the discal region. The under surface 

 very generally resembles that of the two preceding species, while the 

 transverse median and subterminal dark shade bauds, crossing both 

 pair of wings, are most distinct in E. cenotnis, in which the median, on 

 anterior pair, is more appreciably sinuate. In E. mdancholica the 

 inner (median) bands are less distinct, becoming macular, especially in 

 the female — in E. Merianse, the inner bands are obsolete and generally 

 imperceptible. 



Tho'-ax. bi-crested; head, and thoracic region above, brownish-black 

 in the male, in the female cinei-eous-black. paler laterally in both sexes, 

 tegulre with an interior cinereous stripe. Abdomen, paler brown, not 

 banded, very similar to that of E. venotrus, alike in color in both sexes. 

 The segments are fringed with mixed paler and darker hairs, and two 

 dorsal longitudinal shade lines are very distinct. Underneath the ab- 

 domen is paler than in either E. Merianse or E. cenotrus.
