and emarginate anteriorly, at the sides narrowed ; pubescence pale, 

 that of the occiput and pronotum somewhat yellowish ; apical mar- 

 gins of dorsal and ventral segments 2-5 distinctly fringed, the color 

 of which fringe is white except on the dorsal segments medially and 

 the fifth ventral (which have it golden-brown) ; the first dorsal is 

 rather densely pubescent; clypeus punctured at the sides, bearing 

 two longitudinally parallel carinse down the middle ; front strongly 

 and closely punctured, the vertex and occiput, with exception of a 

 few scattered punctures, impunctate ; scape with scattered punctures ; 

 thorax subopaque, the dorsuluni strongly punctured laterally and 

 anterior!}', impunctate medially ; scutellum and metanotum with 

 scattered punctures ; middle segment above with strong separated 

 punctures, with a smooth, longitudinal, narrow space in the middle ; 

 posterior face concave, impunctate at extreme sides, the lateral mar- 

 gins somewhat sharply carinated ; spines of the legs whitish-testa- 

 ceous, calearia darker ; hind tibite beset with strong, black thorns 

 externally, their longer spur more distinctly spatulate than in con- 

 spicua; wings subhyaline, subfuscous anteriorly and apically, with 

 a purplish iridescence, nervures and stigma testaceous, apex of 

 second submarginal cell very sharply angular in the middle; dorsal 

 segments punctured tow'ard the sides, rather opaque, ventrals shining, 

 the second and third with two, and the fourth with one, transverse 

 series of strong punctures ; pygidium nude, sculptured in such a way 

 as to appear shingled, its apical margin narrowly smooth and testa-

Santarem. One specimen. The strongly angulatpd apex of sec-

 from consplcua and auripilis.

Likely to be confused with angulata, but differs in its golden 

 pubescence of front and dorsulum, the semi-yellowish wings and

 and a fascia on dorsal abdominal segments 1-4, or 5, yellow, those 

 on the second and third, or fourth broad, emarginate anteriorly and 

 narrowly incised with black at the sides, else a small black spot is 

 enclosed by the yellow on each side, on the first segment the fascia 

 narrow and sometimes interrupted medially, on the fourth more or 

 less variable, on the fifth narrow and inconstant; front, occiput, 

 pronotum and dorsulum bearing golden pubescence, that of cheeks,
