 One male, four females, May 7, 1872. 



Incurvaria labradoriella Clem. 



The type of this species in the collection of the American Entomological Society 

 at Philadelphia had only one fore-wing and one hind-wing remaining in 1871, and I 

 was somewhat doubtful whether it was a true Incurvaria. I have had no recent oppor- 

 tunity of examining the specimen. 



Incurvaria acerifoliella Fitch. 



The neuration of this species differs from that of the typical Incurvarice, in that veins 

 5 and 6 of the hind- wings arise from the same stem. The case-bearing habits of the 

 larvae, rather than the structural appearance of the imago, probably influenced Clemens 

 and Chambers in placing it finally in this genus. 



Incurvaria mediostriatella Clem. 



'=:Lecithocera? flavistrigella Wlsm. 



When describing Lecithocera ? flavistrigella I was practically unacquainted with Jw- 

 curvaria mediostriatella Clem. The type examined by me in 1871 having only two wings 

 remaining and these much worn, I failed to recognize my species by the description, 

 and was guided chiefly by the long and stout antennte in placing it in the genus 

 Lecithocera. I have now examined the neuration of a specimen and am bound to ad- 

 mit that it does not belong properly to that genus. The apical vein of the fore-wing 

 is furcate near the base, as stated by Clemens, and in this respect it differs from the 

 type of the genus in which he has placed it ; nevertheless, I think that the position is 

 approximately correct. 



CECOPHORA Latr.
