I have examined four specimens of this species, two males and two 

 females, all from Argentina, South America. Two of these, a male 

 and a female, determined by Kohl, agree quite closely with Hand- 

 lirsch's description of the species. Of the other two specimens that 

 I have referred to this species, the male has the fascia on the scutel- 

 lum interrupted at the midline and also has the discal spots on 

 tergites 4 and 5 separated from one another as well as from the 

 lateral spots on these same tergites. On the female the discal spots 

 on tergite 4 are separated as on the male. On both male and female 

 the maculations on the sternites consist of rather widely separated 

 lateral spots and the sixth sternite of the female is wholly black. 



SPECIMENS EXAMINED 



Argentina: Mendoza (H. Rolle, Berlin W. Det Kohl). 

 Handlirsch reports this species also from Montevideo, Uruguay. 



TRICHOSTICTIA VIJLPINA (Handlirsch)

Monedula vulpina Handlirsch, Sitz. Akad. Wissensch. Wien, Math.-Nat. CI., 

 vol. 99, 1890, p. 138.— Dalla Torre, Cat. Hym., vol. 8, 1897, p. 501. 



Of this species I examined two males and two females, all from 

 Chile. The species resembles the preceding but is not quite so slender 

 and the maculations on the thorax are less extensive. The macula- 

 tions on the sternites are almost pure white and the pubescence on 

 the propodeum is long, dense, and white, characters that serve to 

 distinguish this species from the other two belonging to the genus. 



SPECIMENS EXAMINED 



Chile: Santiago (December, 1922, A. Faz) ; Southern part (M. J. Rivera). 

 Handlirsch reports this species also from Peru. 



TRICHOSTICTIA BRUNNERI, new species 



Type (male). — Black: labrum; mandibles, except tips; clypeus, 

 except small pair of discal spots and narrow border on baso-lateral 

 margins; spot between antennae; scape and first two segments of 

 flagellum below; narrow vertical stripe below anterior ocellus; 

 broad anterior orbits deflected inward above anterior ocellus;
