description alone I can find no means of distinguishing them. The 
status of the former will have to await study of further material, 
especially of male specimens, from Argentina. 
10. EUDEJEANIA NUDITIBIA, new species 
A species of the group with silvery hairs on the tibiae and tarsi, 
differing from all other known species by the absence of anterodorsal 
bristles on the hind tibia. 
Male, female—Typical habitus and structure of Hudejeania, speci- 
fically characterized as follows: Head predominantly yellow, the 
frontal stripe black, parafrontals brown, face whitish, epistoma deep 
brown, parafacials, cheeks, and occiput smoky golden; occipital hairs 
yellow above, whitish below; palpi black; antennae black, sometimes 
the second segment slightly reddish at the extreme apex, the third 
segment of the male not broadened at the base; width of the front at 
the vertex in the male approximately one-third the width of the head 
(0.33) ; female with proclinate frontoorbital bristles (2 pairs in the 
holotype, 1 pair in each of the female paratypes). 
Body black in ground color, the thorax brown-pollinose above and 
gray on the sides; no acrostichal bristles, and 2 or 8 pairs of pre- 
sutural and one of postsutural dorsocentral bristles, at least in the 
type series. 
Wings brown, the veins reddish; subepaulet (basicosta) orange. 
Legs: Femora and tibiae black, the tarsi bright yellow, pulvilli 
sometimes brown; tibiae and tarsi covered with silvery white, ap- 
pressed hairs, which are especially dense on the tibiae and conceal 
the ground color except in certain aspects; femoral bristles and hairs 
and the tibial bristles black, tarsal bristles yellow, and claws yellow 
with black tips; hind tibia without anterodorsal or other bristles 
except at the extreme apex. 
Length of body (exclusive of spines), 15-16 mm. (Ecuador fe- 
male only 13 mm.) 
Type.—Female, U.S.N.M. No. 58280. 
Holotype, female, Usaquén, Cundinamarca, Colombia, 2,700-3,000 
m., October 3, 1939 (H. Osorno). Allotype, Bogota (B. Guevara). 
Paratypes: female, Bafios, Oriente, Ecuador, 8-10,000 feet, January 
4, 1923 (F. X. Williams) ; female, Venezuela, 1923 (De Ballard). 
Type series in the United States National Museum. 
11. EUDEJEANIA ANDEANA, new species 
Similar to nuditibia and argyropus, differing from the former in 
having anterodorsal bristles on the hind tibia, and from the latter by 
bright yellow tarsi.
