posteriorly) differs from epacra (smoothly curved dorsally). The paraphyses dif- 
fer greatly in length in the two species, those of epacra being short. The ante- 
ocular black line extends farther forward in caucaensis than in other species of 
the genus. 
Fusigonalia yapacapa, NEW SPECIES 
FicurE 465, PAGE 566 
Length of male 5.1-5.5 mm, of female 5.6-6.0 mm. Head with median 
length of crown varying from slightly more than three-fourths to eight-tenths 
interocular width and from slightly less than one-half to slightly more than 
one-half transocular width, antennal ledges in lateral view with anterior 
margins convex. Thorax with pronotal width approximately equal to trans- 
ocular width of head. Male plates with uniseriate macrosetae; style extending 
posteriorly approximately as far as apex of connective, narrowly rounded at 
apex; connective Y-shaped; aedeagus in lateral view abruptly broadened just 
posterior to base, extending posterodorsally and slightly bisinuate, apex 
slightly broader and broadly convex, shaft without processes; paraphyses with 
a short basal unpaired portion, rami contiguous, extending dorsally, their 
apices slender, tapering, slightly divergent. 
Crown with median black vitta not unusually broad for genus, its lateral 
margins slightly convergent anteriorly, the median vitta at posterior margin of 
head with width approximately equal to combined adjacent widths of yellow 
vittae which separate it from the anteocular black vitta on each side; the 
yellow vittae extending posteriorly over pronotum to include basal scutellar 
angles and to unite with yellow claval vitta (see generic description); corial 
yellow vitta not extending anteriorly very far into anterior half of wing; trans- 
verse anteapical band extending to outer margin of inner apical cell, mid- 
costal marking weak, amber; face with black anteocular band extending 
across anterior margin of antennal ledge and tapering to a point; remainder of 
face, venter, and legs, pale yellow, dorsal portion of thoracic pleura black and 
continuous with black lateral pronotal margin. 
Holotype male and twenty-six additional specimens representing both sexes, 
Santa Cruz, Bolivia (J. Steinbach) (MCZ); and one male, Las Juntas, Bolivia 
(Steinbach) (CM). 
F. yapacapa, n. sp., is similar in many respects to F. lativittata (Fowler), from 
which it may be easily separated by the form of the paraphyses (fig. 465h) of 
the male, and externally by the corial pale vitta which extends more an- 
teriorly in Jativittata. 
Fusigonalia metaensis, NEW SPECIES

Length of male 5.8 mm, female unknown. Head with median length of 
crown approximately seven-tenths interocular width and more than four- 
tenths transocular width, antennal ledges in lateral view with anterior margins
