THE MYCETOPHILIDA. 147 
at the tip of the radial vein. Length 2} to 3 lin. Common in most 
places. 
B. maculipennis, Wik. 
B. fusca, Mg. = -, M. hybrida, Mg. 
Viteteds Saundersii, Curt. 
This is a larger species than the former. Schiner describes 
it as brown, Walker as ferruginous; the only one I have seen 
is brownish. Thorax with three dark longitudinal stripes. Head 
brown, palpi pale or yellowish. Antennz brown, pale at the base. 
Fic. 31.—Bolitophila fusca. A=base of antenna enlarged. 
Legs yellow, tibiz and tarsi brown. Wings pale, grayish-yellow in 
colour, with a gray spot at the tip of the prebrachial areolet, and a 
large brown spot by the costa at the tip of the second longitudinal 
vein. This is a rarer species than the former, and may be known by 
its lighter colour and the presence of the spots (2) on the wings. 
The habits of the larvee of this genus seem to resemble those of 
Mycetophila. “The larva spins a cocoon which remains on the sur- 
face of the ground, or among the fragments of the decayed fungus.”* 
SECTION 7.—Mycetobine. 
Antenne 17-jointed, not long. Brachial vein long. Sub-costal 
rudimentary, third, fourth and fifth veins forked.
