Engel considered pallipes, sensu stricto, to be a form with whitish- 
yellow tarsi, tibiae gray black in ground color but covered with silvery 
hairs, and brown-black femora. In the light of present knowledge of 
variation in the group, Macquart’s brief description (“Pieds d’un 
jaune pale; cuisses antérieures testacées”) shows that Engel quite 
probably misidentified the species. 
Macquart’s type came from Bogota, and we are fortunate in having 
in the National Museum collection a long and unusually fine series of 
specimens of H'udejeania from that vicinity. Two species are present 
in numbers, presumably being common there, and either of these might 
have been the original of Macquart’s species. One species, labeled 
pallipes by Aldrich, has orange tibiae with black bristles and orange to 
brownish femora. This is apparently the form determined as pallipes 
by Van der Wulp,‘ who also had material from Bogota in addition to 
specimens from Costa Rica and Panama. ‘The other species has en- 
tirely reddish-yellow legs with bristles and hairs of the same color. 
The latter might have been pallipes of Macquart, but since the type of 
the species was long since lost and that point can never be determined 
I believe it best to continue the Van der Wulp and Aldrich identifica- 
tion of the species. ; 
Engel recognized only one species of the black form with black palpi, 
namely £’. pallipes (Macquart), and considered melanawz as a synonym 
and argyropus and pyrrhopoda as varieties.. Townsend (1939, p. 79), 
on the other hand, expressed the opinion that these “varieties” of Engel 
“are no doubt valid species, which interbreed at times to produce hy- 
brids with intermediate characters.” The present study corroborates 
Townsend’s view that several distinct species are involved.
