AET. 5 GENERIC EEVISION OF THE FOSSOBIAL WASPS — PARKER 25 



STICTIA HEROS (Fabricius) 



Bemhex hcros Fabricius, Syst. Piez , 1804, p. 222. 



Monedula lieros Handlirsch, Sitz. Wissensch. Wien, Math. -Nat. CI., vol. 99,

/Stictia heros and tiie two species immediately following, viedea 

 and antiopa, are distinguished by having only widely separated 

 lateral spots on the tergites and relatively few or no maculations on 

 the thorax and propodeum. The maculations on the tergites of 

 heros are a pale creamy color, almost white, whereas those on medea 

 and antiopa are decidedly yellowish and the wings of heios are less 

 heavily infumated than are those of the other two species. I have at 

 hand 2 males and 11 females of this species, of which one female 

 bearing the label, " Panama " has been determined by Handlirsch. 



.SFKCI.MENS EXAMINED 



Ecuador: Posorja. 



Panama: Ancon, Canal Zone (L. H. Dunn) ; Old Panama (May 15, 1909, A. H. 

 Jennings; Jan. 31, 1911, A. Busck). 



Handlirsch reports this species from Montevideo, and also from 

 Rio Grande do Sul and Santa Catherina. Brazil. 



STICTIA MEDEA (Handlirsch) 



Monedula medea Handi.iksch, Sitz. Akad. Wissensch. Wien. Math.-Nat. CI., vol. 

 99, 1890, p. 109.— Daixa Torre, Cat. Hym., vol. 8, 1891, p. 498. 



I have before me from Brazil four females that I have referred to 

 this species. All bear fasciae on the metanotum; on three the curved 

 fascia on the propodeum is continuous, on the fourth interrupted; 

 on one the fascia on the scutellum is continuous, on a second it is nar- 

 rowly interrupted, and on the other two it is reduced to lateral spots. 

 On all four the maculations are a bright light yellow. 



I have before me also a male from Surinam determined by Kohl 

 as belonging to this species. Handlirsch did not have a male at hand 

 when he described the species, and if Kohl has published a descrip- 

 tion of the male, I have not seen it. The maculations on the tergites 

 of this specimen are more yellowish than in the case of the males of 

 heros, but the difference is not so great as in the case of the females 

 of the two species. The sixth segment of the flagellum and also the 

 three apical segments are deeply excavated, much more so than is 

 true of heros. Furthermore, the apical surface of the lateral spine 

 on the seventh tergite of heros \% distinctly excavated, whereas in 

 the case of medea the lateral spine is bluntly rounded at the apex.
