The species which I recognize as pallipes Macquart (=pallipes of 
Van der Wulp and Aldrich, not of Engel) is characterized as follows: 
Body color black; parafacials and cheeks smoky golden to brown; 
occiput and occipital hairs dark gray-yellow; palpi black; antennae 
black to dark brown, the second segment narrowly reddish apically; 
subepaulet orange-yellow; legs predominantly yellow, the tarsi whitish 
yellow, tibiae yellow to orange, the femora deep orange becoming fus- 
cous toward the base; tibial bristles black; hind tibia typically with 
three anterodorsal bristles, the basal one weak and sometimes not evi- 
dent; tibial and tarsal hairs silvery white, but the tibiae less thickly 
covered than in argyropus and others, and ground color readily evi- 
dent; dorsal surface of the hind tibia with two rows of silvery hairs. 
Material examined, 89 specimens: Cotomsra: 16 males, 67 females, 
Bogota (B. Guevara) [U.S.N.M.]; male, 2 females, Monserrate, Bo- 
gota, 2,700-3,000 m., May 2, 1940 (#), and August 7, 1939 (H. 
Osorno) ; 2 females, Usaquén, Cundinamarca, 2,700—3,000 m., October 
8, 1939 (H. Osorno) [Inst. Cien. Nat.]; female, above Guasca, Cun- 
dinamarca, 3,300 m., February 20, 1942 (E. A. Chapin) [U.S.N.M.].

The essential characters of E'. melanaz are as follows: Body color 
black; parafacials and cheeks silvery white except for a small trian- 
gular area posterior to the vibrissa; occiput silvery white, the hairs 
white; palpi black; antennae black, the second segment obscurely red- 
dish at the apex; males with subpyriform third antennal segment, 
about 1.7 times as broad at the base as at the apex; subepaulet brown 
to black; femora and tibiae entirely black, the tarsi more or less 
infuscated apically, at least the metatarsi yellow, in extreme cases 
only the distal tarsal segment infuscated above; tibiae and tarsi densely 
covered with silvery white appressed hairs; tibial bristles black; hind 
tibia typically with three anterodorsal bristles, the basal one weak; 
dorsal surface of the hind tibia densely covered with hairs on its 
entire length. 
The strongly developed third antennal segment mentioned by 
Walker is characteristic only of the males, though the females have 
the segment slightly more expanded than in some of the other species 
of the genus. The females can be distinguished from those of argy-
