the right size for Hortensia, and I compared the wing with Oman’s (1949a; 
plate 32, fig. 7) illustration. It agreed fairly well, including the extent of the 
membrane. I place it in Hortensia provisionally.

KEY TO MALES OF HORTENSIA 
(H. innotata (Walker) not included) 
Aedeagus in caudal view with shaft not abruptly broadened apically 
sumilis (Walker) (figs. 654, 655) 
Aedeagus in caudal view with shaft abruptly broadened apically 
dilatata, n. sp. 
Hortensia dilatata, NEW SPECIES 
FiGuRE 656, PAGE 810 
Length 6.0-6.2 mm. Head in lateral view with anterior margins of antennal 
ledges vertical; face with muscle impressions distinct. Thorax with pronotal 
width less than transocular width of head, lateral margins parallel. Other ex- 
ternal structural characters as in generic description. Male with style ex- 
tending posteriorly farther than apex of connective; aedeagus in caudal view 
with apex membranous and bearing a number of denticulate ornaments, the 
whole apical one-third abruptly broader than shaft; other male genital charac- 
ters as in generic description. Female abdominal sternum VII as in H. similis 
(Walker) (fig. 654:). 
Ground color of crown, pronotum, and scutellum olive-yellow except 
pronotal disk which is dull green; head and anterior submarginal area of 
pronotum with dark markings that are weak and disjunct except a median 
postapical black marking which is more pronounced; face yellow with a 
mediobasal spot, and arcuate markings on muscle impressions, black; fore- 
wings green except membrane; venter and legs, yellow. 
Holotype male and one female, La Forestiére, French Guiana, upper 
Maroni River; and one specimen, lower Maroni River, July (NCS). Holotype 
on indefinite loan to USNM. 
H. dilatata, n. sp., can be separated with certainty from H. similis (Walker), 
only by the shape of the aedeagus, which is never abruptly broadened apically 
in the Walker species. In addition to the type-series, I have seen a male (not 
presently at hand) from Tocumen Province, Panama. The species appears to 
be rare.
