LECTOTYPES OF HAGEN SPECIES 
BELONGING TO CERTAIN FAMILIES OF 
TRICHOPTERA 1 
By Herbert H. Ross

During the course of study of the Hagen material be- 
longing to the primitive families of Trichoptera it appeared 
desirable to designate lectotypes of those species repre- 
sented by a type series. This material is in the collection 
of the Museum of Comparative Zoology at Harvard Uni- 
versity, Cambridge, Massachusetts. Lectotype specimens 
have been so labelled. In addition to these, a few unique 
types have been recorded here for convenience. 
The species treated belong primarily to the families 
Philopotamidae, Psychomyiidae, Hydropsychidae and Rhy- 
acophilidae, plus one or two in other families. The species 
are listed alphabetically, first by the genus in which they 
were originally described, then by the species names given 
by Hagen. In certain genera such as Macronema, Hagen 
included species of great taxonomic diversity; for clarity 
all species described by Hagen in such genera are treated 
here. 
In addition to the labels indicated the specimens noted 
bear also the Hagen Collection label. The English transla- 
tion of the label is given.
