Specimens Examined. — Two males. One, merely labelled 
“Bras.,” in V. v. Roder’s collection at the Zoological Insti- 
tute of the University of Halle a. S., is a very old faded 
specimen, on a short pin, and may have been one of Wiede- 
mann’s cotypes. The other is labelled “Chapada,” a locality 
in the southern part of the State of Matto Grosso, Brazil. 
This appears to be the first definite locality for the species. 
Lichtwardt only saw Wiedemann’s cotypes at the Berlin and 
Vienna Museums. 
Both males I have seen agree in having a well-developed, 
though narrowed frons below the ocellar triangles; their 
venation is practically identical. The specimen from 
Chapada is the larger, its wing being 10.5 mm. long; that of 
the other specimen measures 8.5 mm. 
Subfamily Hirmoneurinae 
The Hirmoneurinae should contain all nemestrinids with 
a well-developed, but short and broad proboscis, the labium 
ending in large, fleshy labella. The alula of the wing is al- 
ways broad and the ovipositor of the female is telescope- 
shaped, consisting of several narrow segments capable of 
retraction within one another. In North America, this sub- 
family is represented by two genera, Hirmoneura Meigen 
and Hyrmophlaeba Rondani.
