Erechtites hieracifolius. Fire-weed. 



Phyllocnistis erechtitisella, Cham. Imago unknown. Larva in a long, 

 narrow, linear, winding mine in upper surface of the leaves.

* In Washington, D. C, in January, I have found empty mines of two species of Ti- 

 neina, both of which are undescribed. They were found in leaves of different species 

 of Holly. One mine is probably that of a Lithocolletis larva, of the flat group, in leaves 

 of I. opaca. The other is probably that of a Nepticula, and was in leaves of another 

 species.
