Holotype and one additional male, Volcan, Chiriqui, Panama, 6,000 ft., 
June 1939 (VJ. R. Slevin) (USNM). 
S. rhypha, n. sp., may be distinguished readily from S$. prava by the male 
pygofer processes and the darker color.

Type-species: Hortensia filicis Metcalf and Bruner (1936a:928). 
Length of male 5.5-5.9 mm, of female 6.3 mm. 
Head moderately produced, median length of crown varying from one-half 
to seven-tenths interocular width, and from slightly less than one-third to 
four-tenths transocular width, anterior margin obtusely subangulate in dorsal 
view, without a carina at transition from crown to face, ocelli located before a 
line between anterior eye angles, each closer to median line of crown than to 
adjacent anterior eye angle, crown convex and without a transverse concavity 
across ocelli, without a median fovea and without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins oblique and rectilinear, 
ledges not carinate dorsally; clypeus flattened, muscle impressions not dis- 
tinct, transclypeal suture entire or obsolete at middle, clypellus not strongly 
produced, its contour continuing profile of clypeus. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae usually incomplete, 
posterior margin concave, disk without sculpturing or pubescence; scutellum 
not striate behind transverse sulcus. Forewing with membrane variable but in- 
cluding inner apical cell and not including basal portion of third apical cell 
nor any part of outer apical cell, veins not elevated, distinct, with three closed 
anteapical cells, with four apical cells of which the base of fourth is more 
proximal than base of third, without an anteapical plexus of veins, texture 
coriaceous and without sculpturing; forewing of female in rest position ex- 
ceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1; length of 
first tarsomere equal to or greater than combined length of two more distal 
tarsomeres, and with two parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced posteriorly, apical margin 
smoothly convex, with a number of elongate macrosetae on apical half. Plates 
triangular, extending posteriorly as far as pygofer apex, with uniseriate 
macrosetae. Style not extending posteriorly as far as apex of connective, nar- 
rowly rounded apically. Connective Y-shaped with arms widely divergent. 
Aedeagus simple, short, without processes. Paraphyses variably vestigial. 
Female abdominal sternum VII with posterior margin produced posteriorly 
in approximately a right angle but slightly more acute at tip. Genital chamber 
without sclerites. Ovipositor with broad, toothed portion of each second 
valvula extending through most of length beyond basal curvature, teeth few, 
widely separated and with numerous denticles between teeth, with dorsal 
anteapical denticles; apex narrowly rounded.
