Indusia Comminuta, new species
Plate 2, fig. 12
Case cylindrical, straight, about 8 mm. long and 3 wide, ar first sight appearing as if made of sand grains, but under the microscope seen to be covered with minute irregular vegetable fragments, not so closely disposed as to hide the entire surface. Only in one case is avery small short piece of Sequoia leaf employed. Some specimens are distinctly narrower at one end. Very abundant in Tertiary of Kudia River, Siberia. The name Indusia is employed for caddis-cases which cannot be referred to a definitive genus. The reference of this and the next to Limnephilidae is provisional.
