9) was found under leaves in damp earth in woods. Pupae taken on 
une 8, 1874, emerged as adults on the 13th. The species was found 
Iso in the sandy mud of a small brook bed. EH. (E.) flavescens (Beling, 
879:50) was found in sandy, damp earth, H. (£.) sordida (Beling, 1879: 
6, mention only) in wet, sandy earth along brooks, and EH. (L.) lutea 
Beling, 1886: 192-193) in woods, in damp hollows, and along the margins 
f brooks, usually under leaf mold. Edwards (1919 a) has recorded a 
ecies of Erioptera as being associated with the larvae of the mosquito 
aeniorhynchus at the roots of water grass (Glyceria fluitans) in 
ngland. 
In America, EL. chlorophylla, E. vespertina, E. caloptera, and other 
ecies inhabit wet mud in open swamps; LH. septemtrionis and EH. megoph- 
alma, rich organic mud in cool, shady woods; EH. armata, HE. near 
abi, and other species, the soil along the sandy banks of streams. FH. 
cyphona) graphica was considered by Hart (1898 [1895]:197) to be 
miaquatie. 
The writer has before him the larvae of only two species of the genus, 
chlorophylla and E. megophthalma. These are readily separated by 
eir color, EH. chlorophylla being pale green, EH. megophthalma pale 
llow and more elongate. The pupae of the Nearctic species of the 
nus may be separated by the following key:

The adult flies of Hrioptera megophthalma are not uncommon in 
ol, shaded, and boggy woods during the months of early spring.
