Occurs among elms in May and June. I have seen at the end 

 of August minute mines on ehn-leaves, probably caused by this 

 species, but was unable to meet with the larva. The larvae were 

 found by ]\Iann on elms.

Head and face white. Antenaaj white, annulated with fuscous. 

 Anterior wings white, towards the apex irrorated with fuscous, with 

 four costal spots and one dorsal spot fuscous ; the first costal spot is 

 near the base and very small (sometimes entirely wanting), the second 

 and third are obliquely placed, one on each side of the middle, the 

 fourth lies in the apex ; the dorsal spot is opposite the second and 

 third costal spots, and uniting with them forms an angulated fascia ; 

 on the inner edge of this spot in tlie fold is a black (ht, and a black 

 dot lies beyond the apex of the third costal spot ; cilia whitish, tra- 

 versed by two dark hinder-marginal lines. Posterior wings grey, with 

 paler cilia. 



Abundant in June and July among buckthorn, the leaves of 

 which plant are at first mined, and afterwards eaten from the ex-
