HEMISTEPHANIA. 
Doryfera, Gould, P. Z. 8. 1847, p. 95 (nec Illiger, Coleoptera). 
Hlelianthea, «. Hemistephania, Reich. Aufz. d. Col. p. 9. 
Hemistephania, Elliot, Syn. Troch. p. 81 (ex Reich.). 
A well-defined genus, distinguished by its long, straight, even slightly upturned bill, 
the tomia of both maxilla and mandible being finely serrated ; the nasal covers are fully 
exposed, the frontal feathers only reaching their proximal ends. The tail is short and 
rounded. In several respects Hemistephania resembles Androdon, especially in the 
form of the tail; but the latter genus shows much more strongly serrate edges to the 
cutting-edges of the bill, and the male has a well-defined terminal hook to the 
maxilla. 
Four species of Hemistephania are now recognized, three of them being closely allied, 
whereof the only species in our region is one. The fourth member of the genus, 
H. johanne, is more distinct, and enjoys a wide range, extending from the Andes of 
Colombia and Ecuador to Guiana. 
As Gould’s name Doryfera for this genus, though an appropriate one, has been 
previously used by Illiger for a genus of Phytophagous Coleoptera, Reichenbach’s 
subgeneric title, Hemistephania, raised to generic rank by Mr. Elliot, must be 
employed. 
The range of Hemistephania extends from Costa Rica to Bolivia, and eastwards to 
the mountains of British Guiana.
