 "Face, i)alpi, under surface and leg.s silvery wbite, the legs marked on their 

 anterior surface with golden and brownish spots and bands: tuft white, golden 

 at the side.s; antennse silvery white beneath, above golden brown, faintly annu- 

 late with whitish ; thorax and anterior wings bright golden ; upon the wings is 

 a short snow-white median basal streak strongly dark margined behind and 

 within. (Sometimes tlie anterior margin and sides of the thorx are also white.) 

 Two snow-white fascise, one at about the ba.sal one-fourth, the other about the 

 middle, both strongly dark margined behind, and sometimes slightly so inte- 

 riorly; and both strongly angulated posteriorly near the costa ; with the first 

 sometimes slightly interrupted at the angle, and the dark margin of the second 

 posteriorly produced. A long oblique snow-white dorsal streak at the base of 

 the dorsal cilia posteriorly dark margined, and a smaller costal one a little behind 

 it at the base of the costal cilia, similarly dark margined. This dorsal streak is 

 sometimes posteriorly produced, and confluent with a straight dorso-apical 

 streak, which is faintly dark margined behind, but is sometimes entirely want- 

 ing. When present it forms the interior border to the apical dusting. Some- 

 times the costal streak is produced so as to be confluent with it also, and opposite 

 to it there is sometimes a costo-apical white spot which is separated from it by 

 the apical dusting, which extends thence to the apex and is black upon a white 

 ground. Hinder marginal line in the cilia dark brown. Cilia golden. Alar 

 expanse one-fourth to one-third inch." 



The species, of which the above is the original description, is 

 common iu the eastern United States. 



The larvae form large blotch mines on the upper surface of leaves 

 of white oak, Querciis alba L. One mine will often contain from 

 several to a dozen larvie. The loosened epidermis is brownish yel- 

 low, somewhat puckered, and often covering nearly the entire leaf.
