female, 12°8 mm.; pronotum 11°5 mm.; posterior femora 7°6 mm. 
One example from Paramba, Ecuador; Rosenberg. 
Genus ScaARIA, Bolivar. 
1. S. fasciata, sp. nov. 
This is a remarkably graceful species, narrow between the 
shoulders, and having the pronotum anteriorly only little ascendant. 
Body granulate, flavo-ferrugineous, on either side bearing a broad, 
black, longitudinal fascia, the face, lower part of lateral lobes of 
pronotum and sides flavous, legs flavous, often tinged with fuscous. 
Eyes strongly globose; face oblique; vertex subtruncate, nearly 
equal in width to one of the eyes, scarcely advanced so far as the 
eyes, little narrowed forward and smooth, the median carina wanting; 
the frontal costa starting at the vertex little lower than the eyes, 
divides between the posterior ocelli and is arcuately protuberant 
forward between the eyes; superior ocelli large, conspicuously 
showing in profile just in advance of the middle of the eyes. 
Pronotum anteriorly acute spiniform produced, the antero-dorsal 
margin on either side of the spine roundly excavate, posteriorly 
lengthily extended beyond the apices of the hind femoral knees ; 
dorsum between the shoulders convex, narrow; humeral angles 
bicarinate ; anterior prozonal carinz only little expressed, slightly 
divergent backward ; median carina somewhat undulate, often little 
compresso-elevated forward between the shoulders, nearly horizontal, 
and forward at the front margin with the spine little ascendant and 
uncinate. Elytra oblong, with a pale spot near the apices varying 
in intensity and size ; wings fully explicate, extended beyond the 
pronotal apex. Posterior femora elongate, knees black, the superior 
carinz forward black, with pale spots ; tibize black but pale annulate 
toward the base and the apices, the canthi serrulate and rather feebly 
plurispinose ; the three pulvilli of the first tarsal articles equal in 
length. Length of the body entire, male and female, 13-15 mm.; 
pronotum 11-14 mm.; posterior femora 5:5-6°3 mm.
