Ichthyura inversa n. sp. 



Smaller and of a darker color than the preceding species, and with 

 the costa of the fore wings more convex. The light portions of the 

 primaries of /. inciusa are in this species densely dusted with brown 

 scales. The reddish brown line from the vertex on to the crest is nar- 

 rower than in that species. The basal line is dislocated as usual, but 

 the lower portion is slightly waved, as are the lines without, which are 

 situated as in /. inciusa, but waved. The inverted V on the discal 

 nervules is more distinct; the brownish tinged subapical region border- 

 ing the upper half of the fourth line is narrower, and of a deeper red 

 than in the preceding species, while the submarginal series of linear 

 spots is not so distinct. A lighter line crosses the secondaries beyond 

 their middle. 



Beneath a little darker ; a common line much more distinct than in 

 /. inrhis'i is margined with reddish on the costa of the primaries. 



Length of the body S .55, 9 .65; exp. wings % 1 inch, 9 1.30 inch.

 broad brown line from between the antennae to top of the crest. Basal 

 line straight, with an outward fold. Second line arcuated outwards, 

 meeting the short third line on the median nervure. The fourth line 

 extends only to the second, making a short Y. On the outer third of 

 the costa a deep white oblique spot, which is the termination of the 

 partially obsolete fourth line. This spot is surrounded by deep reddish 

 brown, which is much darker towards the apex. A submarginal slightly 

 arcuated series of dark spots. Secondaries with no transverse line. 

 Beneath concolorous with the upper side of the secondaries. Indented 

 spot margined with brown on the costa, but fainter than on the upper
