TWO NEW SPECIES OF CADDICE-FL1ES.

By NATHAN BANKS.

The _following two

_species of caddice-flies

were

collected at

Wellington,

^British

Columbia, by two

local collectors,

Rev. G.

W. _Taylor and Mr. Theo.

Bryant.

Both

_{are large}

and

_striking species,

one handsomely marked

^{for a} caddice-fly^; the otherof rather peculiar shape.

One

of

them

constitutes a

new _genus, GlypJtopsyche, which

includes also a species recently described as Glyphotcelius ^{bellus. I}

have named

the species ⁱⁿ

honor

ot the collectors,

who have done

so

much

to

make known

the insect fauna of theirregion.
