A European plum leaf -miner . — Nepticida slingerlandella, the American 

 form, is closely related to the European species A'', plagicolella Stainton, 

 which also feeds on the cultivated plum. The moth of A'', slingerlandella 

 differs from plagicolella in having the marginal cilia of the wings much 

 whiter ; the facia across the forewing is a silvery white, while in plagicolella 

 it has a distinctly golden hue. In the American species the color of the fore- 

 wing is distinctly black with a bronzy hue, while in plagicolella it is narrowly 

 before the fascia and altogether beyond it of a reddish purple bronzy hue. 



The following account of the European pltmi leaf -miner is condensed 

 from an extended summary of its habits by J. W. Tutt (British Lepi- 

 doptera, i, pp. 272-275. 1899). 



Adult. — Head reddish. Anterior wings 4-5 mm. ; shining fuscous with 

 a purple tinge nearly from the base; beyond the middle is a nearly straight, 

 shining, rather silvery, transverse fascia; cilia dark blackish gray. Pos- 

 terior wings and cilia pale gray. 



The egg is laid on the upper side of a sloe leaf.
