Habitat. — Peru. Holotype, 9 , Matucana, Peru, altitude 7788 
feet, July 14, 1914 (Parish coll.). 
The specific name is that of the native Indian nation of 
Peru. 
This interesting species is readily separable by the gray thorax 
with the prominent dorso-median brown vitta and the gray and 
white diversified wings. The subterminal yellow annulus to the 
femora is a character not found in the near relatives of this 
insect. 
Tipula carizona Alexander 
1913. Tipula carizona Alexander, Journ. N. Y. Ent. Soc, xxi, p. 208, pi. 7, 
fig. 7 (wing), figs. 2 to 4 (genitalia). 
A male from Matucana, Peru, altitude 7788 feet, July 14, 1914, 
collected by Parish; another male from Huancayo, Peru, alti- 
tude 10,636 feet on June 27, 1914, Parish, collector. 
This species is quite widely distributed in the Andes; it differs 
from Van der Wulp's description of ornaticornis by the light gray 
color of the thorax instead of opaque rufous.
