only slightly pectinated. On the hind-wings the lowest dis- 

 coidal nervule is widely separated at its base from the upper 

 sub-median nervule, instead of being stalked with it, as in the 

 typical Arctiida. In shape and general appearance these 

 Moths greatly resemble some of the Ithomiince or Hiliconina 

 among the Butterflies, and several species are more or less 

 transparent, like many of the Ithomiince. 



GENUS CALODESMA. 



Calodesma^ Hiibner, Verz. bek. Schmett. p. 177 (1822?)

In Calodesma the fore-wings are shorter and less rounded at 

 the tips than in some of the allied genera. The moths are 

 black, more or less suffused with brilliant blue, especially 

 towards the base, and are generally marked with a broad 

 transverse hyaline-white band on the fore-wings, and some- 

 times also on the hind-wings. 



Other species have bright scarlet bands instead of white 

 ones.

This species was brought from the Tapajos, a tributary of the 

 Amazons, by the late Mr. H. W. Bates. It measures nearly 

 two inches in expanse.
