 Since the foregoing pages were written, I have been suc- 

 cessful in rearing N. saginella from leaves of oaks, collected 

 during the latter part of July ; and I am therefore able to 

 say definitely, that while the Nepticuliform mines in the 

 leaves of the chestnut may be produced by the larva of Buc- 

 culatrix trifasciella, those in the leaves of oaks are certainly 

 the work of a Nepticula miner. 



The mines in chestnut leaves are shorter than those in oak 

 leaves, although very similar in appearance. 



The following is a table of the species described to the 

 present time. 

 Fore-wings without spots or fascia?. 



Pale ochreous, dusted with blackish- sacjinella. 

 brown. [p. 175.] 



F. w. with a white spot and a costal streak. 



Dark brown. Platanella. 



[pp. 173 & 183.] 

 F. w. with pale or silvery fasciae. 



Blackish-brown ; fascia median, curved. Rubifoliella. 



[p. 152.] 

 Purplish-fuscous ; fascia oblique, rather fuscotibiella. 

 broad. [p. 182.] 



Bronzy-green ; with two fasciae. hifasciella. 



[p. 183.] 



* Here stress is laid upon the " white tarsi," but in the table of the genus 

 we read " legs with white tibia" Either tarsi or tibia is probably a mis- 

 print, but without knowing the insect described it is impossible to say which 

 is the erroneous expression. H. T. S.
