The genus Dolichopeza is a small group of flies including about a score 
of species, most numerous in the Oriental and Australian regions. The 
immature stages of the European Dolichopeza albipes Strém, a species 
that is very close to the American species D. americana Needm., have 
been described by Beling (1879, 1886). He found larvae in and beneath 
moss cushions covering the piles of waste copper slag in the Harz Moun- 
tains. On June 11, 1878, larval and pupal material was taken from a 
tussock of the Jungermanniales liverwort Alicularia scalaris Corda. ‘The 
pupal period was found tobe six days. Females were noted depositing their 
eggs in these hummocks, and small swarms of males were observed dancing 
near by. It appears that the larvae feed on the upper side of the moss 
cushion at night, withdrawing into the interior at other times. A larva was 
found in earth, which shows that these larvae are not dependent on mosses. 
The larva is described by Beling (1886:189-191) as being about 12 
millimeters long and 2.3 millimeters in diameter. The body is almost 
terete. The color is a rather bright green, the dorsum being marked 
with two zigzag dark brown stripes. The spiracular disk has but five 
lobes; the three dorsal lobes are long and narrow, the median tooth being 
formed by the apparent fusion of two teeth; the ventral lobes are very 
short, are tuberculate, and have a small, dark brown, triangular mark 
at the inner tip. There is a small dark cross-stripe at the base of each 
lateral lobe. The spiracles are small, are circular, and are separated by 
a distance equal to about one and one-half the diameter of one. Beneath 
each spiracle is a rather large, irregular, blackish brown spot. The anal 
gills are strongly protuberant. The pupa measures about 14.5 millimeters 
in length and 2.5 millimeters in diameter. The pronotal breathing horns
