THE NEW WORLD 
By F. M. Hull

Recent studies of American Syrphid flies have dis- 
closed a number of species of Volucella which appear to 
be undescribed. This paper presents the descriptions 
of these species. The types are in the author’s collec- 
tion. 
Volucella splendens n. sp. 
This bright purplish to bluish species is related to 
macula Wiedemann. It is distinguished by the general 
color of the abdomen and the rusty orange red face with 
conspicuous lateral flattened areas on either side of the 
tubercle. Length 14 mm. 
Male. Head: the face, cheeks and the front, except 
for a small brown triangular callus, are entirely pale 
rusty orange in color. The facial tubercle is large and 
elongate, more abrupt below, with a patch of blackish 
pile in the middle and the remainder of the facial pile red. 
The frontal pile is reddish in the middle and the sides but 
with some black pile in the junction of the eyes. Anten- 
nae light brownish orange, the third segment elongate, 
narrow upon a little more than the apical half and this 
apical portion with parallel sides in the male. Eyes 
holoptic for a long distance, flattened above with the up- 
per facets greatly enlarged and the ocular pile dense and 
long and pale brownish yellow. Vertical pile black. The 
pollen of the face is restricted to the upper portion be- 
neath the antennae and is distinctly pale brownish yellow. 
The sides of the upper portion of the face on either side 
of the tubercle are distinctly flattened leaving a rather 
sharp ridge laterally and a corresponding well marked 
crease beside the tubercle; the intervening area is flat- 
tened. Thorax: the mesonotum is shining black, becom- 
ing diffusely brown on the notopleura, the humeri, the 
intervening area, the margin above the wing and the
