24 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxn. 



The larva pupates within the mine without much of a cocoon, and 

 the adults go through the characteristic undulating motion before 

 settling down to the typical position of rest. 



1 have very little hesitation in identifying this species as the one 

 described by Packard as a Bucculatrix for the following reasons: No 

 species of Buccalatrix is known to feed on evergreens; the descrii)tion 

 fits the present species very well, as does the figure, which, although 

 poor, looks like an Argyrestlda., but could hardly have been drawn 

 from a Bucculatrix. Packard had rather vague ideas of the genera 

 of Microlepidoptera, as is abundantly proven by his description of 

 Nepticula pomivorella as a Mlcrojjteryx, and of Tinea fuscipuncteUa 

 Haworth as Oecophora frigidella; a large number of the small, very 

 peculiar parasite Pentacneinus hucculatricis Howard, which was de- 

 scribed from Packard's specimens, were also bred from my material; 

 the cocoons which Packard descril^ed and associated with his species 

 did, according to his description, not look like those of a Bucculatrix 

 and probably belonged to the Recurvaria tkuyella., common on the same 

 plant and also bred from Doctor Fletcher's material. 



However, there is, of course, a possibility of a Bucculatrix feeding 

 on Thuja, and if such is ever found Packard's name must revert to 

 that species; but I consider this very improbable.
