CICADELLINAE: PART 2, NEW WORLD CICADELLINI 967 
of two more distal tarsomeres, and with two parallel rows of minute setae on 
plantar surface. 
Male genitalia: Pygofer moderately produced posteriorly, apex varying from 
broadly rounded to narrowed and subacute, macrosetae from few to many, 
located on posterior half of disk and in most species on the dorsal portion of 
that region. Plates extending posteriorly as far as, or farther than pygofer 
apex, usually with uniseriate macrosetae (without macrosetae in H. balloui 
Metcalf and Bruner) and usually with a number of microsetae. Style ex- 
tending posteriorly to a varying degree in comparison with connective, but 
never extending as far as apex of latter, truncate apically, with lateral lobe oc- 
curing almost opposite articulation with connective. Connective T- or Y- 
shaped with arms widely divergent. Aedeagus with shaft short, with or 
without processes, occurring near midlength when present. Paraphyses absent 
or present, symmetrical or not, in some species with only a single apical 
ramus. 
Female abdominal sternum VII with posterior margin moderately produced 
-and rounded, angulate, or slightly concave at apex. Genital chamber without 
-sclerites. Pygofer usually as in Hortensia (fig. 654c) (exception: ballout, in which 
the macrosetae are more numerous and more closely set and arranged dif- 
-ferently). Ovipositor with second valvulae each expanded throughout portion 
beyond basal curvature and with large quadrate teeth usually extending 
almost to apex (exception: H. ¢trinitalis Metcalf and Bruner) and bearing 
minute secondary denticles, with a number of anteapical dorsal denticu- 
lations, apex angulate or narrowly rounded, with or without an anteapical 
posteroventral angle. 
Species of Hadria Metcalf and Bruner occur in Cuba, Haiti, and the 
Dominican Republic. Hadria is closely related to Apogonalia Evans, sharing 
with it the presence of the subantennal sclerite which rests along the lateral 
clypeal suture. The structure is usually less distinct than in Apogonalia and ap- 
pears to be wanting in H. maestralis (Metcalf and Bruner) and obscure in 
some other species. The peculiar venation of the forewing, with its two very 
short anteapical cells both lying entirely more distal than the claval apex, will 
readily separate Hadria from other genera. Of the species moved to Hadra, 
from Arezzia, in the list below, there might be some hesitancy in following this 
disposition of maestralis (Metcalf and Bruner) which is the type-species of the 
nominal genus Arezzia. But the venation of the forewing of maestralis is like 
that described above for Hadria, and the genitalia of a male paratype of 
maestralis are so much similar to the present illustration of H. trinitalis Metcalf 
and Bruner that I cannot find specific differences (although I believe they are 
distinct species). 
The present interpretation of Hadria ballou. Metcalf and Bruner is based on 
paratypes of both sexes compared with the female holotype. Arezzza baracoa 
Metcalf and Bruner is known to me only from the male holotype, of which the 
_ forewings are missing, and from the allotype of which the abdomen and a 
fragment of the thorax bearing one hindwing are all that remain (I have not 
dissolved the balsam in the gelatin capsule in which the genitalia of the holo- 
type are imbedded).
