We have now described typical specimens of our collection. It 
must be borne in mind, that they are all from one limited locality, 
except one axe, and that collectors may now have or may discover

Psyche helix, Solenobia triquetrella and lichenella, Apus cancriformis

gist desirous of knowing how to observe and how to study. 
There are twenty-one observations concerning Apus reported from 
the years 1857 to 1869 at four different localities, in Bohemia, 
Croatia, Poland and Italy. The number of collected and investi-
