Baccha cybele n. sp. 
A black species, the wings sepia brown with only the 
apical fourth hyaline. Second, third and fourth seg- 
ments of the hind tarsi white. Related to clarapex 
Wiedemann. Length 9.5 mm. 
Male. Head: the vertex is bluish black and shining, 
moderately raised, the black pile lies in a single row ; the 
posterior lateral eye margins are deeply incised in the 
middle; there is a long row of silvery occipital pile be- 
hind, tine and non-scalose, long in the middle becoming 
blackish towards the top of the occiput; along the in- 
dented area of the eye there is a double row of long tine 
black hairs which are replaced by white ones on the lower 
part of the occiput. The occipital pollen is greyish white 
but the black hairs arise from minute black punctate 
spots. Front black, faintly bluish and in some lights 
with an azure blue reflection. The upper third of the 
front is opaque black bordered by brown pollen and in 
turn the brown pollen bordered with a spot of silvery 
pollen which lies on the upper eye margin and is visible 
only from above. The antennal callus is large, shining 
brownish black, narrowly and diffusely brownish yellow 
along the sides in the middle of the face only. The cheeks 
are metallic black; the sides of the face are widely white 
pubescent or pollinose; the tubercle is rather sharp, 
gently sloping above, somewhat more abruptly below. 
The antennae are dark brown, reddish brown below at the 
base of the third segment. The arista is dark brown but 
lighter at the immediate base. The frontal pile and 
nearly all of the basal is black. Thorax: the mesonotum 
is black, moderately shining with a pair of very obscure, 
reddish brown pollinose spots on either side of the middle 
of the anterior margin ; the entire anterior margin is more 
narrowly but similarly pollinose. There is a still more 
obscure, narrow, greyish streak down each side of the 
mesonotum reaching nearly to the transverse suture. 
The pleura are wholly metallic black, thinly whitish polli-
