A common species in our region. I have a very large series before me, showing 
great variation in colour—from bright chrome-yellow to almost white. Costa Rican 
specimens are generally paler than those from elsewhere. 
4. Heterusia basilata.

(Ribbe), Volcan de Chiriqui 2000 to 3000 feet (Champion), Veragua (Arcé, in mus. D.). 
—Co.LomBiA; Ecuapor; Braziu}, Rio Janeiro 2. 
I consider H. basilata (Guen.), of which I have a very large series before me, to be 
quite distinct from H. conduplicaria, Hiibn., with which species Walker has placed it. 
HT. basilata is a much whiter insect. 
5. Heterusia anicata.

Hab. Mexico, Jalapa (I. Trujillo), Las Vigas (coll. Schaus); Guatemala, Duefias 
(Champion).—CotomB1a, Bogota; Ecuapor. 
I have only seen four specimens of this insect from within our limits; but from 
Ecuador I have a good series.
