labelled type, so we selected the best and supplied it with a type label 

 bearing a note of the circumstance. We are not acquainted with the 

 European teticrii with which Walsingham compares his species, and 

 so must accept his decision that they are distinct.

 Bright golden brown, about the same color as pcriscclidactylus. Antennae 

 white with brown spots above. Palpi brown at the sides, the vestiture of the 

 second joint produced into a point below which almost reaches tip of third. 

 Legs brown and white striped, fore and middle tarsi with each joint partly 

 brown on one side. Hind legs banded and striped as in the preceding species. 

 Abdomen with diverging white dashes above and some white scales in the 

 posterior half below. 



Wings marked as in raptor, from which they differ conspicuously in color. 

 Expanse 13-20 mm. 



Distribution: N. J. to ^Mass. and Quebec. S. Cal. to B. C. Early 

 Tune to early Aug. We have seen a single speciinen from \'an-

This is the only North American species belonging to the group 

 characterized by the tufted second papal joint and weak, membra- 

 nous claspers. 



Zeller described this species from a single male from the Dela- 

 ware River which should now be in the British jMuseum. Unfor- 

 tunately we had not yet placed the species when we submitted speci- 

 mens to Mr. Meyrick for comparison with the types in that institution, 

 but from Walsingham's notes in the "Pterophoridae of California and 

 Oregon" we feel that its identity is sufficiently well established. The
