Note 1211 — LETTER XLVII.
Reading edition
From θριξ, τριχος, hair. Mr. MacLeay, thinking it indisputable that the Perlidæ should be included in this Order, suggests the propriety of changing its name, both as inapplicable, and as being preoccupied by a Dipterous genus. As I do not think the Perlidæ belong to the Order, and as the great body of the Trichoptera are distinguished by hairy upper wings, I cannot think the name improper: but to apply a name to a Genus which terminates like the denominations of Orders, I think leads to mistakes, and should not be tolerated.—K.
