deflected away from the eye-margins and narrowed ; posterior orbits 

 broad below; narrow posterior border of pronotum; sides of pro- 

 thorax, except irregular bjack spot in front of tubercles; short 

 lateral lines above base of wings and pair of narrow longitudinal 

 discal lines on scutum ; narrow fascia on posterior border of scutellum ; 

 narrow fascia on posterior border of metanotum; curved fascia on 

 propodeum, broadened and interrupted at midline on posterior sur- 

 face ; lateral angle continuous with Jarge spot on side of propodeum ; 

 large spot on metapleura; smaller spot on mesopleura; broad, con- 

 tinuous fasciae on tergites 1-5; fascia on first tergite with a median 

 anterior emargination extended to right and left, thus producing a 

 large, flattened, heart-shaped area in the fascia; second fasciae 

 with a wider but shallower median anterior emargination partly 

 inclosed; third and fourth fasciae each ajso with a shallow median 

 anterior emargination; large apical heart-shaped spot on sixth ter- 

 gite ; lateral spots connected by narrow apical lines on sternites 2-5 ; 

 spot on anterior coxa; femora in part; tibiae, except line above and 

 one below on anterior pair and line below on middle pair; and 

 tarsi ; pale tinged toith light creamy yellow. 



The flagellum is black, paler below. The frons is broad and the 

 inner eye-margins are parallel. The dorsal border of the clypeus at 

 the midline is extended upward between the antenna, forming an 

 angle whose apex is above a line marking the lower level of the inser- 

 tion of the antennae on the frons (fig. 96). Although this modi- 

 fication in the form of the dorsal border of the clypeus is not unique 

 with this species, it is more pronounced than on any species I have so 

 far seen. The frons between the antennae and the dorsal part of the 

 clypeus are distinctly carinate. The anterior matatarsus bears six 

 spines. The wings are hyaline. The sixth tergite is triangular in 

 outline, rather narrow, and roundly pointed at the apex. The second 

 sternite is uniformly, closely, and finely punctate throughout its 

 entire surface, with here and there a few somewhat larger punctures 

 scattered over it. 



With the type I have associated as a paratype a single female that 

 may prove to be a female of another species. It is more slender than 

 the type ; this is particularly evident with regard to the thorax. The 

 color of the maculations on the abdomen is distinctly greenish yellow. 

 In other respects, including the form of the clypeus and the punc- 

 tation of the second sternite, it agrees so closely with the type that 

 under the circumstances I am forced to regard it as a variant of this 

 species. 



Length about 17 mm. Described from two females, of which the 

 type bears the label, " Brasilien, St. Cath. Joinville, Schmalz S. V.," 

 and the paratype, the labels, " Brasilien, Freir. S." and " 3738 Bras."
