334 THE WHITE COFFEE—LEAF MINER. 
It was referred to under the same name by Nietner in his 
pamphlet on the enemies of the coffee-tree in Ceylon. 
Vernacular names. — Guérin-Méneville, who described it as com- 
ing from the Antilles, called it “ L’Elachiste du Cafier.”* 
In Brazil it is called “ A Borboleta do Cafezal,” the coffee-plan- 
tation butterfly or moth, but I should think it much more satis- 
factory to unite accuracy with definiteness by giving it the name 
of the White Coffee-leaf Miner, because other species of moths 
are found also living on the cdffee-tree, and a black coffee-leaf 
‘miner (Gracilaria? coffeifoliella) is known in Ceylon. 
Erroneous names.— This is probably the insect referred to 
doubtfully as a Bucculatrix (?) by Stainton in the “ Entomologist’s 
Weekly Intelligencer,” vol. iv (1858), p. 70. 
mago.—The outspread wings of the perfect insect (imago) 
measure from tip to tip between four and six millimeters. The 
body is about two millimeters long. Silvery white scales cover 
the head and face, the body below, the upper side of the front 
wings, and the legs, except the tips of the first, second and 
fourth foot-joints (tarsi), upon the upper side of which the scales 
are black. In my specimens, which are not in good condition, me 
upper side of the hind-body (abdomen) is bare and of a yellowish 
brown color. The antennæ are smoky black, except at the base 
The front wings are long in proportion to their breadth. On the 
upper side of each, at the extremity of the inner edge (inal OF 
gle) is a large steel-blue or black spot, which has a violet lustre. 
This spot is bordered on the sides towards the base and front peel 
of the wing by a golden-yellow band, which is continued "e 
the end of the wing. At more than half the distance from 
base of the wing to the tip, arises from the front edge = 
another golden-yellow band, with converging sides, bene 
each edge with black scales, which runs obliquely toward the black 
spot, and sometimes almost reaches the golden edging of f 
spot. Beyond an interval of about the width of this band gee 
the tip of the wing (apex) arises another band of the same Hi ' 
but wider and shorter, and bordered only on the inside with 
scales. This band runs less obliquely toward the bla a 
but does not meet the other bands. About as far beyond eo 
ond band as that is beyond the first, a line of black scales
