A NEW SPECIES OF THE TORTRICID^. 



BY PROF. C. H. FERNALD, AMHERST, MASS. 



Argyroploce abieta?ia, n. s. — Expanse of wings, 21-23 mm. Head, 

 thorax and fore wings dark brown, varying somewhat in intensity of colour, 

 some specimens being lighter than others, caused more or less by yellowish- 

 brown scales intermixed with the dark brown. This is especially notice- 

 able in specimens taken in Amherst, Mass., as compared with specimens 

 taken in Maine. The fore wings are crossed by three silvery-white bands, 

 the first of which, arising from the basal fourth of the costa and ending at 

 the basal third of the hinder border, is divided by about three fine, 

 thread-like, irregular dark brown lines extending across the wing through 

 this band which receives, near the middle, an outward angle or tooth of 

 varying form, from the basal brow^n part of the wing, and there is some- 

 times a similar one on the outer side. The second band arises from two 

 small geminate white spots on the costa above the end of the cell, the 

 stripes from which unite at the end of the cell, and this band ends at the 

 outer fourth of the hind margin, and has a dark brown tooth extending 

 into It on the inner side on the median vein. The sides of this band are 

 irregular, caused by indentations from the dark brown on each side. On 

 the costa, beyond the costal origin of the middle band, are two equidistant, 

 geminate, silvery-white streaks, the first of which is short, while the other 

 extends downward, giving off two branches in succession, to the outer 

 margin above the middle, and is often connected below with a similar 

 stripe extending up from the anal angle, and also giving off branches to 

 the terminal margin. Fringes dark fuscous, with a darker extrabasal line. 



Hind wings and abdomen above fuscous, with lighter fringes, wiiich 

 have a darker extrabasal line. Under side of fore wings fuscous, w^ith the 

 geminate costal spots reproduced beneath. Under side of hind wings, 

 thorax, abdomen and all of the legs fuscous, the tarsal segments tipped 

 with w'hitish. 



Described from three male specimens taken in Amherst, Mass., one 

 of which I make the type, and four males from South Paris, Maine, sent 

 to me by Miss Edith M. Patch, Entomologist at the Maine Agricultural 

 Experiment Station at Orono, Me. Miss Patch wrote me as follows : 

 "On May 20 I received from South Paris, Maine, webbed twigs of spruce 

 containing pupae of a Tortricid which had ruined some small spruces. 

 The moths began to emerge May 29."
