NEW SPECIES OF EXOTIC SYRPHID FLIES 
By Frank M. Hull 
U niversity of Mississippi 
Some time ago, Professor Nathan Banks placed in my 
hands for study an interesting collection of Syrphid flies 
that had accumulated in the collections of the Museum of 
Comparative Zoology. These flies have come from many 
sections of the world and, as was to be expected, include a 
number of new species, the descriptions of which are pre- 
sented in this paper. Notes on the occurrence and distribu- 
tion of other species will perhaps be published at a later 
date. I wish to thank Prof. Banks for the opportunity of 
studying this interesting assortment of Syrphids as well as 
for the facilities for study in the Museum which he so kindly 
placed at my disposal. 
Meromacrus melmoth n. sp. 
Male. Eyes narrowly joined. Vertex slightly raised, 
black. Face and front black, conspicuously yellowish white 
pilose along the sides of the front, on the eye margins, run- 
ning down the sides of the eyes and thence to the oral margin 
as a diagonal facial stripe. This leaves the face obscurely 
shining black, the black as a V-shaped wedge below antennae, 
reaching to oral margin, its widest part at the base of the 
antennae. Cheeks shining blackish. The facial stripe be- 
neath the sparse pile is whitish pruinose and much more 
conspicuous than the pile. The pile on the sides of the front 
assumes the curious appressed character typical of the genus. 
Occiput and lower part of vertical triangle below the ocelli, 
similarly colored, pilose and pruinose. Face somewhat cari- 
nate. Antennae blackish brown, the third joint lighter 
brown, extraordinarily truncated dorso-apically and coming 
to a rounded point, the arista basally thickened, yellow, quite 
pale at tip, and twice as long as the third joint. 
Thorax, pleurae, and scutellum dull black, except that the
