Family Mycetophilidce 
Sciara sp. One specimen, July 17. Some species of this 
genus are mycetophagous, developing in fleshy fungi. 
Family Chironomidce 
Culicoides sp. One specimen, July 16. Accidental; this is a 
phlebotomic type with aquatic larva. 
Family Scatopsidce 
Reichertella femoralis Meigen. One specimen, July 17. 
Family Scenopinidce 
Scenopinus fenestralis Linne. Three specimens, July 20-28, 
September 26. This is the common “window-fly” frequently 
seen in houses. The larva is carnivorous and has been reared 
from the preparatory stages of the clothes-motm 
Family Phoridce 
Aphiochceta pulicaria Fallen. Eight specimens of both sexes, 
July 14-August 23. 
Aphiochceta agarici Lintner. One female, July 17. The 
larvae live in various fleshy fungi. 
Aphiochceta sp. One female, July 28. This is probably an 
undescribed species with swollen, heavily chitinized proboscis. 
Aphiochceta sp. Eight specimens, July 18-August 23. Sim- 
ilar to A. iroquoiana Malloch, but probably an undescribed 
species. 
Family Muscidce 
Muscina stabulans Linn. Two specimens, August 8. The 
larvae of this fly are predatory upon other dipterous larvae. 
Family Trypetidce 
Pseudotephritis vau Say. Two specimens, July 23 and August
