Characters of the Family. 
Habits, (See. 
The larvae of the Mycetophilidse are generally cylindrical, 
attenuated towards both extremities, soft, fleshy, smooth or a little 
wrinkled, moist, often viscous, more or less translucent, witli 
twelve more or less clearly determinable segments in addition to 
the head. Stigmata placed one [)air on the first segment of the 
thoracic region and one pair on each of the abdominal segments 
from the first to the seventh inclusive. Head horny. Short palpi 
and mandibles occasionally present, and also generally rudimentary 
antennso. 'I'lie above is a very general summaiy of the characters; 
a more preci.se one it is ditlicult to dr<aw for the reason that the 
larvse vary somewhat in form. Comparatively little appears to 
have been observaul and recorded with regard to the liist stages 
and life-histories of the Mycctophilidac, and nothing whatever has 
yet been dope in thi.s direction in Australia.
