the transition to the following. The contours of the wings correspond about to those of venosa. Body and wings 
are black with a blue lustre; basal palpal joint, sides of the head, shoulders, and anus yellow. Expanse of wings:

white spot at the cell-end, the hindwings a small one below the cell-end. Brazil (<$). 
C. subsemistria Strand from Argentina is closely allied to the preceding. The hindwings are dull black sub-

C. editha Wkr. (26 e) is a relatively broad-winged species with intensely lustrous blue body and wings, editha. 
Palpal base, chest, venter, and the dorsum of the 2nd to 5th abdominal rings are scarlet. Known only 
from Hayti.

The body is greenish-black, the abdomen with whitish ring-indentations. The head is orange, so are the margins 
of the collar and shoulder-covers. Brazil (Rio cle Janeiro, Rio Grande do Sul), Chile, Argentina. — In lativitta lativitta.

suffused with metallic blue, the hindhead scarlet, the shoulder-covers are striped orange. A very common 
animal from North America, supposed to be distributed as far as Ecuador. How far the southern habitats 
refer to the forms of the following species is a mooted question. The southernmost habitat to be determined 
to a certainty by myself, is Mexico. 
C. rubrovenata Rothsch. is smaller than venosa, the wings shorter and more obtuse, the head black, rubrove-
