Genus Ituxa, Doubleday. 



IlUNA ALBESCENS, U. SJ). 



Front wings pale oclireous, transparent, with the following dark fuscous 

 opaque markings : — A wide streak occupies one-half of the interno-median 

 interspace. A somewhat broad band extends from costa through middle of 

 cell, along first median nervule, to outer margin; a second band of about 

 the same width commences on subcostal nervure and crosses end of cell 

 along second median nervule to outer margin. These two bands coalesce 

 on the median nervure. A somewhat obscure and interrupted band crosses 

 wing between apex and end of cell. The costal and outer margins are of 

 the same colour, broadest at the apex and least at the costa between the 

 first and second bands. Inner margin rufous. Hind wings ochreous, trans- 

 parent, a dark fuscous opaque costal margin extending along second subcostal 

 nervule to outer margin, which is broadly of the same colour. Under sides 

 as above ; the dark fuscous is of a bright chocolate colour ; a few white 

 spots at apex of front wing, and a marginal row of same coloured spots to 

 hind wings. Exp. 4 in. 2 lin. 



Dr. Staudinger has kindly examined this species, and says it is quite 

 distinct from a similar form he has lately described from Pebas, and which 

 was a true Eutresis.

Size and general appearance of 21. Lycidice, Bates, from which it prin- 

 cipally differs by the less elongate and more rounded form of the wings, the 

 greater narrowness of the three yellow belts, and in the hind wings by the 

 only rudimentary and obscure appearance of the black discal stripe, and 

 the total absence of the yellow streak on the disk. The general colour is 

 also somewhat brighter and more pronounced.
