I have noticed the larva and its mines in abundance at Providence 
in September and October. " 
The following notes have been furnished by Professor Eiley: 
Received July 5, 1SS4, from X. H. Bishop (Griswold collection), Daveuport, Iowa, a 
lot of leaves of different kinds of oak. badly infested with larva of the above insect. 
On some of the large leaves the entire upper surface was undermined. The same in- 
sect is also very common on all kinds of oak on the Agricultural grounds at Wash- 
ington, D. C. The moths commenced to issue July 12 to July IS. and at the same 
time quite a number of four different species of parasites issued. | Unpublished notes.) 
The moth has white front wings, with three broad irregular bronze bauds across 
each one. each band being bordered with black on its inuer side. The hind wings 
«ry. The wings expand .2S inch. (Comstock.)

The mine of this insect is represented at A in Fig. 62, which has been 
identified by Mr. W. Beutenmuller, who thinks that the other mine (at 
C) is the work of a Nepticula.
