GREATER ANTILLES 1

The material on which this paper is based was collected a 
few years ago by Dr. P. J. Darlington in the hilly country of 
Hispaniola and Puerto Rico, and is deposited in the Museum of 
Comparative Zoology. The two groups discussed — the Neo- 
tropical Paricanine Tropiduchidae and the Kinnaridae — ap- 
pear to have their maximum number of genera and species in 
the western Caribbean area and to be comparatively poorly 
represented in the Americas outside this region. Whether the 
Paricanini of the Old World form a natural group, and whether 
they are truly co-tribal with the Caribbean generic complex are 
problems which must wait for solution until the Asiatic species 
have been critically studied. For the time being the writer pro- 
poses to regard the tribe as extending to America, and lists the 
following characters as being common to the Neotropical genera 
that are assigned to it: vertex usually longer than wide, pos- 
terior margin deeply concave, disc depressed, ecarinate, or with 
median carina very prominent in the depressed area, or re- 
placed by a vertical plate; frons much longer than wide (1.5 to 
1 or longer) with a broad longitudinal median raised band, 
lateral margins sinuately expanding to near fronto-clypeal 
suture that incurved; head in profile usually with lateral mar- 
gins curving evenly from vertex into frons; pronotum short, 
median carina prominent, disc not bounded by lateral carinae, 
or if so bounded then narrow and strongly eminent; mesonotum 
short, flattened, scarcely half as wide as long; tegmina with a 
nodal and an apical line of transverse veins, apex of clavus situ- 
ated near or basad of middle of commissural margin, subapical 
cells not exceeding six, apical rarely exceeding twelve; post-
