ANNETTE F. BRAUN. 333 



verse streak, made up of a cloud of black dusting, narrowly separated from the 

 dusting of the second costal streak. Cilia yellowish gray, yellowish around the 

 dusted portion, and without lustre. 



Hindwings gray, their cilia lighter. None of the markings reappear upon the 

 underside of the forewings. 



ID addition to the above description, Zeller has noted another 

 form of this variable species, in which the dusting, especially that 

 in the apical portion, is much less dense. 



Very widely distributed, occurring from New Jersey to Ohio, 

 southward and westward to Texas and California. 



The larvae form blotch mines on the upper side of leaves of vari- 

 ous species of oak. The pupa is formed under a flat, nearly circu- 

 lar silken cocoon. I have a series bred from live oak, Quercus Vir- 

 giniana Mill, from Fortress Monroe, Va., showing all intergrades 

 between specimens having the deflexed dorso-basal streak extending 

 unbroken nearly to the costa, and those in which it is nearly over- 

 laid with black dusting. The figure represents a specimen of the 

 former variety. There is a median white streak on the thorax not 

 mentioned in the description. The character "hind tarsi pure 

 white" is by no means constant or reliable, as several specimens 

 have the first tarsal joint very distinctly tipped with black. 



A series in the National Museum, bred by Mr. Busck on live oak 

 from Willis, Texas, is darker, more densely dusted, and has the 

 antennal joints very distinctly annulate all the way to the base. 



Alar expanse 7.5-9 mm.

"Face and palpi silvery white, tuft white, intermixed with golden. Antennae 

 silvery white, the apical two-thirds annulate with brownish. Legs and under 

 surface silvery white. Anterior wings bright golden, inclining to orange, with a 

 white streak along the dorsal margin from the base to the cilia, where it is de- 

 flexed and passes on to the dusted portion of the apex which is near the posterior 

 margin, and is dark brown on a white ground. There are three small costal sil- 

 very streaks, the first and second being near the middle of the costal margin, 

 and the second one the largest, while the third is small and near the apex. 

 There is some variation in the size of the third costal streak and in the extent of
