EXOTIC MICROLEPIDOPTERA, 
Diptychophora azanalis Walk. 
Of this species (Brit. Mus. Cat. xix, 967, 1859) I regard parvalis 
Walk. Cat. xxxiv, 1316, 1865, and Kuhlweini Zell., Stett. Ent. 
Zeit. 1866, 154, pi. i, 13, as synonyms ; it is the type of the genus. 
There is some geographical variation, but the forms are not separ¬ 
able, and the species is quite distinct from any other ; I have it 
from Gfuiana, Brazil, and Peru.
