notched brown spot below it extending to the sinuous margin of the pronotum. The 
outline by the profile view is very convex and tapers to a sharp point. Tegmina

with one small apical area at the tip, and also three others less remote. The discoidal 
areas two. Legs tawny ; abdomen black.

ARGANTE SEMIFASCIA. 
(Plate XLI. fig. 1, the ? .) 
Genus : ANTIANTHE, Fowl. 
Janthe. Stal Ofv. Kongl. Yet, Ak. Forh. 1867, p. 554. Fowl. l.c. p. 137. 
One characteristic of this genus is that the pronotum is laminated almost like the 
genus Membracis proper, and that the metopidium is carried perpendicularly to a 
considerable elevation, even slightly overhanging the head. The corium has two 
discoidal areas, and the hind tibiae are furnished with spines. Species are difficult 
to determine with precision. The tibiae are not spatulate. 
ANTIANTHE EXPANSA.

Janthe expansa, Stal, l.c. p. 554. 
Pronotum elevated, compressed, of an obscure or greenish yellow ; the dorsal 
ridge marked with conspicuous but small dots; suprahumerals sharp and long. 
A common and widely spread species, occurring over all Central America. In 
some localities the examples are very small, but the size is not dependent on sex, for 
many small individuals prove to be females, which commonly are the larger forms 
of sex amongst the Membracidae. 
Size, 1G x 8 to 7 x 4 mm. 
Habitat. —Mexico, Vera Cruz, Belize in Honduras, Costa Bica, Bogota, Columbia.
