1941] New Species of Syrphidse 
blunt knob. Wings: tinged with pale brown, darker about 
the stigma. 
One male. Tjibodas, Mt. Gede, Java, 7800 ft., 1909 
(Bryant and Palmer). Type in the Museum of Compara- 
tive Zoology. 
A very remarkable resemblance to Eristalis tenax and to 
a honey bee. It is certainly very close to Shiraki’s species 
mimica. Nevertheless, it appears to me that the hind femora 
of apimima are more strongly thickened and incrassate and 
that the arista has some forty dorsal bristles to twenty-four 
or twenty-five in mimica, judging by Shiraki’s figure. 
Volucella nitidithorax n. sp. 
A large shining black species with yellowish brown face 
and yellow tinted wings. It belongs to the V. nigricans 
group. 
Male. Length 18.5 mm. 
HeoA: eyes densely black hairy, the black pile of the 
vertex twice the length that of the eyes, fine and bristly. 
Front protuberant, small, black bristly. Antennse and thick 
plumose arista orange brown, the third joint small, short, 
barely longer than broad and tapering quickly to a rounded 
point. The face has the appearance of being dark shining 
brown with a wide, shining, brownish-yellow middle stripe 
from base of antennse to oral margin. Yellow stripe covered 
with numerous fine black bristles interspersed in which are a 
few pale ones, all beginning just above the tubercle. The 
tubercle or knob is prominent but flat, leaving the face deep- 
ly excavated below the antennse. Occiput black, black 
pruinose, with very short black pile. Thorax: and scutellum 
shining black, covered on the former with very dense, erect, 
fine black, bristly hair. There are some quite long black 
bristles on the upper pteropleurse, sides of thorax and scutel- 
lum. Humeri dark brown. Abdomen : dorsally and ventrally 
shining black, covered with thick, short, black bristles, quite 
appressed, a little longer on fourth and fifth segment. Legs: 
entirely black, black pilose. Hind femora quite slender. 
Wings: suffused with yellow. More prominent on the veins 
and brownish along the posterior terminations of the veins.
