New Species of Syrphidse

the metanotum. Abdomen: black, everywhere thickly punc- 
tate, the middle of the second segment brownish, the post 
border of this segment completely and of the third segment 
incompletely in the center with narrow pale yellow bands. 
First segment half as long as second, third a trifle shorter 
than fourth and first two segments a trifle longer than third 
and fourth, if viewed laterally. The yellow bands encircle 
the venter and the sides of the last ventral segments are 
emarginate. The first two segments are very slender, and 
the last two suddenly swell at base of the third into a com- 
pact subglobose body amazingly suggestive of certain wasps. 
The third and fourth segments are thus fused and the fourth 
bears faint whitish interrogation marks. Legs: brown, 
marked with light yellow, the basal and apico-dorsal and 
medial parts of the first femora, last two fore and mid tarsi, 
base and ventral surface of mid femora and a basal annulus 
of hind femora are light yellow. Legs punctate. Wings : 
margined with yellow, a darker spot apically and a smaller 
one about the stigma. 
One female, Camerouns, Mete (G. Schwab). Type in the 
Museum of Comparative Zoology. 
Cerioides multipimctata n. sp. 
Allied apparently to Cerioides tredecempunctata Brun, to 
which it traces in his key. It differs in the reddish color of 
abdomen, additional spots on thorax, besides minor differ- 
ences. 
Male. Length 15 mm. including antennae. 
Head: eyes touching for distance of front, which is short. 
Vertical triangle very swollen, yellow, confluent with the 
swollen and thickened upper occiput. Face pale yellow. A 
median black stripe, red on its lowest part, encircles the base 
only of the antennal process and sends out a black diagonal 
downward projecting spur toward but not reaching the eye. 
Cheeks yellow, separated from face by a wide black stripe, 
the middle of which is a reddish stripe. Antennae pedicel as 
long as first and second joint, the first barely longer than 
second. The second and third subequal, the color reddish 
brown ; first and second joints slightly darker than the third ; 
style whitish. Thorax: black, ground color of pleurae black.
