margins almost to midline, black; pronotum with a pair of longitudinal lines, 
interrupted (holotype) or nearly so in anterior half, and a small spot near 
middle of each lateral margin, black; scutellum with basal angles black; fore- 
wings with inner margins of clavi black-bordered almost to their apices, a 
black stripe beginning in outer basal angle of each clavus, crossing claval 
suture near midlength and extending into anteapical cells, thence curved 
laterally to costal margin; costal margin narrowly, and membrane, black; cly- 
peus with an elongate median black spot. 
Holotype male and one additional male, Cairo, Costa Rica, March 22-26, 
1932 (Sofia and C. H. Ballou) (NCS). One female, Musawas, Waspuc River, 
Nicaragua, October 13, 1955 (B. Malkin) (UCAL). Holotype on indefinite 
loan to USNM. 
S. fucatus, n. sp., may be separated from all other species in the genus by its 
lack of an angular spot on the humeral margin of the forewing, by the 
presence of a black spot on the clypeus, by the form of the paraphyses, and of 
the aedeagus. 
Soosiulus fulgidus, NEW SPECIES 
FicuRE 317 
Length of male 8.0 mm, of female 8-3-8.4 mm. Head with median length of 
crown one-half or slightly less than one-half interocular width and ap- 
proximately three-tenths transocular width, ocelli located before a line be- 
tween anterior eye angles, each approximately equidistant from adjacent an- 
terior eye angle and median line of crown; clypeus with muscle impressions 
distinct. Thorax with pronotal width approximately equal to transocular 
width of head. Male pygofer narrower apically than in most species in the 
genus, with a large number of microsetae along basiventral margin; plates not 
extending nearly as far posteriorly as pygofer apex, with very few uniseriate 
macrosetae; style extending posteriorly to a point much less than half length 
of connective, with distinct preapical lobe; connective very elongate, slightly 
narrowed in basal third, thence tapering gradually to rounded apex; aedeagus 
symmetrical, almost straight, ventral and dorsal margins subparallel, the ven- 
tral margin very slightly concave in lateral view, apex abruptly narrowed and 
subacute, without aedeagal processes; paraphysis consisting of very short me- 
dian longitudinal bar at apex of connective. Female abdominal sternum VII 
elongate and with posterior margin produced and regularly convex except 
medially where it is very slightly concave. 
Crown with a basal black marking extending from eye to eye including 
ocelli, and a median apical black spot; disk of pronotum black, broadly 
margined with orange laterally and posteriorly, scutellum black except orange 
apex; forewing orange with an angular spot on humeral margin, an elongate 
angular marking occupying most of clavus, a longitudinal marking beginning 
in basal third of corium and extending almost to base of apical cells, and 
costal margin narrowly, black; face with apical spot of crown continued ven- 
trally as a broad median black spot on clypeus.
