in the Museum of Comparative Zoology. 
Volucella pallidithorax n. sp. (Plate 1, Fig. 8) 
Female. Length 12 mm. 
Head : face descending into a slender cone, quite pointed 
at apex. The tubercle prominent, leaving a concavity below 
antennae but apart from the tubercle the profile of the face 
from antennal base to tip of epistoma is almost perpendicu- 
lar. Front not wide; nowhere wider than length of third 
antennal joint, at vertex over three times the width of ocellar 
tubercle; the ocelli very small and close set. Head every- 
where, except the posterior occiput, post vertex and above 
the cheeks, pale shining yellow. Antennae entirely orange 
brown. Aristal rays long and loose, twenty-one to twenty- 
two above. Pile of eyes not half as high as vertical pile, the 
former pale, the latter black, merging into the long, pale, 
upright pile of lower front. Pile of face short, appressed, 
sparse, golden. Thorax: pale greenish yellow, a brown pair 
of stripes medially, stopping well before the scutellum, an 
outer pair black, interrupted at suture, pointed posteriorly, 
nearly reaching the scutellum. Pleurae and scutellum pale 
yellow, the latter translucent with four very long, black 
bristles on either side not arising from noticeable tubercles. 
Four similar bristles on posterior calli, one on mesopleurae 
and four on sides of mesonotum. Abdomen: pale yellow, 
translucent, a narrow black border posteriorly on the second 
segment, wider at the angles, with a suggestion of a narrow 
median streak. There is a wider similar border on the third, 
with a median black prolongation that reaches the anterior 
margin of the segment. The fourth segment marked much 
as the third. The yellow of the third reaches the margin 
very narrowly but on the fourth reaches the margin in full 
width; pile of yellow areas yellow, of black areas black. 
Legs: yellow, the bases of all of the femora, distal fourth of 
the fore and mid tibiae and greater part of hind tibiae and all 
its tarsi black. Wings: with a yellowish tinge.
