remainder; scutellum brown with a pair of large basal spots and most of 
apical half yellow; forewing brown with three slender spots in clavus and 
three large spots in corium, one on disk near midlength, one bordering costal 
margin opposite claval apex, and the third extending diagonally from near 
claval apex to near base of outer apical cell, orange, and with smaller 
yellowish-orange spots in both clavus and corium; face dull yellow with weak 
brown longitudinal shading over muscle impressions of clypeus, thoracic 
pleura and legs dull yellow except dark apical half of each posterior tibia. 
Holotype and one additional male and one female, Jacareacanga, Para, 
Brazil, October, 1959 (M. Alvarenga) (OSU). 
O. alvarengai, n. sp., is similar in appearance to O. elegantula, n. sp., but dif- 
fers from the latter in its more nearly angulate head in dorsal view, in lacking 
a large median coronal orange spot, and in the more strongly curved aedeagal 
shaft of the male. 
Oragua elegantula, NEW SPECIES 
FiGuRE 511, PAGE 629 
Length of male 7.2 mm, of female 8.4 mm. Head with median length of 
crown varying from slightly more than four-tenths to one-half interocular 
width and approximately one-fourth transocular width, other characters of 
head and pronotum as in Oragua alvarengai, n. sp.; scutellum transversely 
rugulose on posterior portion; forewings as in alvarengai. Male pygofer with 
macrosetae on posterior half and the group extending basiventrally to basal 
half of pygofer; plates extending posteriorly as far as pygofer apex, each with 
uniseriate macrosetae; style not extending posteriorly as far as apex of con- 
nective, without preapical lobe, apex very broadly foot-shaped; aedeagus 
without dorsal apodemes, shaft almost horizontal in lateral view, with a pair 
of apical divergent tapering processes; paraphyses very short-stalked, rami 
more strongly divergent than in other species in the genus, each ramus with a 
short dorsal process near its base. Female abdominal sternum VII as in 
alvarengat. 
Crown black with a broad band bordering each eye and a cuneate median 
spot, orange, apex yellow to orange; pronotum marked as in alvarengar; 
scutellum dark brown with a median basal and an anteapical orange spot; 
forewing brown with basal, middle, and anteapical elongate spots in clavus, 
three oval spots in corium and a transverse vitta across anteapical cells at 
their midlength, orange, a short elongate spot near midlength of costal margin 
and a spot near apex of brachial cell, dull yellow; face, pleura, and legs as in 
alvarengat. 
Holotype and one additional male, Fonteb6a, Amazonas, Brazil (RMS). 
O. elegantula, n. sp., is closely related to O. alvarengai, in the discussion of 
which diagnostic characters are given.
