Lebertia (fig. 92) (and its subgenera) has many species in Europe, one of which has been recorded from Canada, but the American form has much longer hairs than the European specimens. Tyrrellia (fig. 83) was based on a round-bodied, short-legged species from Canada; the palpi are rather short, and the second joint has a spine beneath. To Thyopsis (near Thyas, but without median eye) belongs a remarkable species, T. cancellata Koenike. The entire dor- sum is densely reticulate, the central part with a large and heavy reticulation. Koenikea is represented by one species ^videly distributed in the northern parts of our country. The species of Hygrobates (figs. 87, 88) have soft bodies, the slender legs.
