I have bred a specimen of this species from a mine on nod- 

 ding wild rye, Elymus canadensis L. At first the mine is a 

 mere thread-like line, but gradually increases in breadth until 

 it comes to occupy almost the entire breadth of the leaf. The 

 length of the mine is about 10 or n cm. The pupa is attached 

 to a leaf beneath a few criss-cross threads of silk, not suf- 

 ficient to be termed a cocoon. 



There are several generations a year and specimens appear- 

 ing in the middle and the latter part of summer are duller and 

 have the white markings less distinct and less clearly limited, 

 due to the encroachment of the grayish scales upon them. 



I have not been able to verify Chambers' surmise that the 

 larva of this species mines the blades of "blue grass," al- 

 though I have often captured specimens on lawns and in pas- 

 tures almost exclusively of blue grass; other species of grass, 

 among them the food plant recorded here, are, however, al- 

 ways present. 



Leucanthiza dircella n. sp. 



Head golden, with dark brown hairs behind. Antennae dark brown 

 with the tips silvery white. 



Thorax golden, dark brown in front. Fore wings orange-yellow, 

 with the apical portion dark brown, and a dark brown patch occupy- 

 ing the basal part of the wing on the costa and at the base, but not 

 reaching the dorsal margin. This patch is bordered behind by an 

 almost straight golden fascia extending from costa to dorsum which 

 thus encloses on the dorsal margin, a small patch of the orange-yel- 

 low ground color. Basal angle sometimes with a few golden scales. 

 An oblique somewhat curved golden streak, dark margined on both 

 sides extends from the basal third of the wing near the costa to the 

 middle of the costa. At the beginning of the cilia is a small golden 

 costal streak. Near the middle of the dorsum, is a short golden streak, 

 margined toward the base by an oblique line of dark brown scales. 

 At the tornus is an inwardly oblique and longer golden streak. There 

 is a streak of golden scales just within the margin along the termen, 

 not very distinct in some lights. Cilia dark brown. Hind wings and 

 cilia dark brown. 



Abdomen dark brown above. Legs golden, tarsi dark brown. 



Expanse : 5-6 mm.
