apical segment short with many spinelike setae mesally; aedeagus

Brotoagy.—This species seems to be restricted to the fast waters of 
small highland streams, and it may also breed around the rocky 
margins of Boeri Lake. The larvae make typical trap-nets and sand- 
enclosed retreats. Pupation takes place in a silk and sand cocoon 
attached tightly to a rock in the substrate.

Leptonema albovirens (Walker).—Mosely, 1933, p. 45.—Fischer, 1963, p. 166. 
The species is known from the extreme northeast of Mexico through- 
out Central America, across northern South America to Trinidad, and 
north in the Lesser Antilles to Grenada and St. Vincent. I give only 
a few more pertinent references to this species; a complete bibliography 
is to be found in Fischer (1963).
