second segment; the remainder of the second and the 
whole of the third and fourth segments are shining black. 
The pile is yellow upon the yellow areas of the first seg- 
ments, widely yellow on the third segment, except imme- 
diately along the posterior margin, and yellow upon the 
fourth segment. Second sternite and narrow base of the

Volucella palmyra n. sp. 
A small species related to zephyrea Curran but dis- 
tinguished by the yellow pilose pleura and the entirely 
black front tarsi. Moreover, the entire hind tibiae are 
unicolorous brownish black, not half brown. The de- 
pression of the scutellum is very shallow and oval. 
Length 6 mm. 
Female. Head: the face is rather deeply conical, the 
tubercle moderate but the face very deeply excavated 
above. The face and cheeks are pale yellowish brown 
with a faint trace of a slender brown stripe from epi- 
stoma to eye margin. The facial pile is sparse and short 
and yellow, the yellow pollen restricted to the area be- 
neath the antennae. The front is shining black with only 
the area about the preantennal callus reddish brown. 
The pile of the front and ocellar region is sparse, short 
and yellow, the upper occipital pile behind the ocelli 
black. Eyes with sparse, short yellowish white pile.
