WE have long felt the inconvenience of having a number 
of unnamed species of Rhopalocera in our collection and 
the consequent difficulty of referring to them. We 
propose in this and similar papers to describe such 
species as require names and when necessary to give 
figures of the more notable forms. 
We begin with the American Ithomiine, which require 
a good deal of attention. 
Tithorea furina, sp. 0. 
T. furix, Staud. similis sed fascia anticarum mediana omnino 
maculosa distinguenda. 
Hab. COLOMBIA. 
This is a form of 7. fuwria, Staudinger, but it differs in 
having the band, which crosses the middle of the pri- 
maries through the end of the cell to the middle of the 
outer margin, split up into six separate small spots. In 
T. furia these are partially run ‘together and form a 
, broken band. 
We have six specimens including both sexes, most of 
them obtained by the late T. H. Wheeler during his 
travels in the interior of Colombia. One specimen was 
unnamed in Bates’s collection. 
Lithorea flacillu, sp. n. 
T. furix quoque similis sed quoad maculis anticarum ZT. furine 
proxima, anticis ad basin fere omnino nigris; fascia posticarum 
mediana nigra margine externo conjuncta, maculis tribus flavidis ad 
angulum apicalem differt. 
Hab, COLOMBIA.
