alchimiella Scopoli. He also makes it synonymous with the 

 American maple-feeding Gracilaria packardella Chambers, 

 and with the American oak-feeding species of Frey. 



This is not the case ; szipcrbifrontella Clemens must be re 

 tained as a good species attached to Hamamelis. So must pack 

 ardella Chambers (= elegantella Frey, Stett. ent. Zeit., xxxiv, 

 p. 202, 1873), attached to Acer, while the American oak-feeding 

 species, determined by Frey as supcrbifrontella, may or may 

 not be the same as the European alchimiella Scopoli. I have 

 not sufficient bred material to settle this last point with cer 

 tainty. All of these species are very close and somewhat vari 

 able. Bred specimens, compared with Clemens' type, are in the 

 U. S. National Museum. 



Gracilaria fulgidella Clemens. 



One type, lacking the right fore wing, Clemens' No. 45 ; alar 

 exp., 7.5 mm. 



This is different from any other described American Graci 

 laria, and I have no specimen like it. Clemens' description is 

 very accurate, though it would seem more natural to regard the 

 dark color as the ground color, marked with white, dark- 

 margined fascia?. The species is nearest to Gracilaria asteri- 

 cola Frey and Boll. 



Gracilaria venustella Clemens. 



One type, lacking abdomen and left wing, Clemens' No. 46; 

 alar exp , 6.5 mm. 



There is anotherof Clemens' specimens, labeled 197, the same 

 as this type, and also lacking the left wings. This is evidently 

 the specimen from which Clemens redescribed the species.* 



This is, as determined by Chambers himself,f the same as 

 Gracilaria eupatoriella Chambers. Specimens collected at 

 light in Kentucky and at Washington, D. C., by the writer, and 

 compared both with Chambers' type in the Cambridge Museum 

 of Comparative Zoology and with Clemens' type, are in the U. S. 

 National Museum. The species belongs in Walsingham's genus 

 Dialectica,\ but may remain in Gracilaria Ha worth until the 

 group is worked up. 



Gracilaria strigifmitella Clemens. 



One type, left fore wing missing. Clemens' No. 47 ; alar exp., 

 8.5 mm. 



This is the same species described by Chambers as Gracilaria 

 duodecemliniella and also the same as his Ornix quercifoliella.
