For several years, as a result of various Insect Faunal Surveys in Nova Scotia, material of an undetermined Epipaschid of the genus Tetralopha has been accumulating in our collection. On a recent visit to Washington I could not match the species with any named material in the United States National Museum; in general appearance it is fairly close to Hulst's unique type of talleolalis but very considerably larger; although of approximately the same size as robustella Zell. it cannot be mistaken for this species on account of the very definitely geminate t. a. line, the paler median space and the clearly cut t. p. line, which latter character would also separate it from militella Zell.
