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. Antenna brown, pale at the base. 



Fig. 31. — Bolitophila fusca. A = base of antenna enlarged. 



Legs yellow, tibiae and tarsi brown. Wings pale, grayish-yellow in 

 colour, with a gray spot at the tip of the pra;brachial 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 larvae 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."*

Antennae 17-jointed, not long. Brachial vein long. Sub-costal
