A NEW GRACILARIA ON AZALEA 



{Lepidoptera, Gracillariida) 

 By AUGUST BUSCK 



Gracilarla azaleae, new species. 



Second joint of labial palpi light golden yellow, terminal joint yellowish 

 white with the tip blackish brown in front. Face silvery white, irides- 

 cent. Head and thorax light golden yellow, mixed with dark purple. 

 Forewings dark purplish brown with a large yellow costal area, begin- 

 ning at basaJ fourth and reaching, attenuated, to just before apex; the 

 yellow area is broad at its basal fourth, extending from this space down 

 to the fold, but it becomes abruptly narrow at the middle of the cell and 

 from there outward covers less than a third of the width of the wing ; 

 the yellow area is, however, not very sharply limited except toward base ; 

 the dark purple part is more or less sprinkled with yellow scales in some 

 specimens, so much as to make it the dominant color ; on the extreme 

 costal edge is a series of minute purplish black dots. Cilia dark purplish 

 brown. Hindwing dark purplish fuscous. Abdomen dark silvery fus- 

 cous above wath yellowish white underside. Legs dark purple. Tarsi 

 white with narrow black annulations at the joints ; tibiae on middle legs 

 somewhat thickened with scales. 



Alar expanse : 11-12 mm. 



Habitat: Yonkers, New York, and New Brunswick, New Jersey. 



Foodplant; Azalea. 



Type. No. 16851, U. S. Nat. Mus. 



Received from Dr. E. P. Felt, who has bred a series of the species, 

 March. 1912, from leaf-mining larvae on azalea, and who has asked me 

 to furnish a ncime for the species. 



It was also lately received from Prof. T. J, Headley, New Brunswick, 

 New Jersey, with the note : " On azalea, imported from Germany."
