The four families which constitute this group in Britain areclosely related together; the first three represent three separatelines of development, rising nearly simultaneously from acommon origin in the Ocneriadae, which family is clearly de-rivable from an early form of the Psychidae. The Syntomi-didae (probably not authentically found in Britain ) are anadvanced development of the Arctiadae.
Imago with forewings more or less elongate-triangular, termennot very oblique ; hindwings broad-ovate.
Type of markings. —Forewings with five transverse lines,viz. : subbasal (not reaching dorsum), first, median, second,and subterminal, and three discal spots, viz.: a roundish
