LITERATURE AND HISTORY IN EUROPE. 13 
In some individuals the flesh tints are almost wanting; in others 
they are so marked as to give the impression of a body color of pink 
and even purplish. Individuals reared from the interior of English 
walnuts, where they were concealed from the light, were as a rule 
lighter in color than those that had fed, in a more exposed position, 
upon flaxseed, and the latter were also more strongly marked with 
flesh color. 
The cocoon and pupa.—The cocoon of the fig moth varies accord- 
ing to its location. The specimens that “spun up” in corn meal and 
were covered with particles of the meal varied from 10 to 20 mm. 
in length, outside measurement, but were only about 6 mm. in 
length, inside measurements. Cocoons “spun up” without the cover- 
ing measured from 10 to 12 mm. in length and were 3.5 mm. wide. 
Inside they are lined with exceedingly fine, delicate white silk. 
The pupa, as would naturally be expected, resembles closely that 
of LF. huehniella, but is of a lighter color and smaller, measuring 
between 7 and 8 mm. in length, and is about four times as long as 
wide. 
LITERATURE AND HISTORY OF THE SPECIES IN EUROPE. 
This species was first described by Francis Walker in 1863,!¢ and 
later redescribed by Zeller in 1867,? from two examples from Cairo, 
Egypt, as E'phestia cahiritella. It was subsequently redescribed in 
1875 by Barrett,’ who called it /. passulella from its occurrence in 
the so-called Corinthian raisins or currants (“ Passule corinthiace”». 
This is a fruit of a small variety or species of grape, in this country 
universally called “currants.” To distinguish it from other species 
that infest dried fruits the writer suggested calling it, after the 
later Latin name, the dried-currant moth. 
Walker and Zeller in their descriptions say nothing of the habits 
of this moth, and Barrett said only that it was “ locally common in 
currant warehouses ” in London and that it fed upon dried currants. 
He observed, however, that it had the singular hovering flight, 
common to the Indian-meal moth (Plodia interpunctella) and Ephes- 
tia elutella, that it was “ exceedingly active and lively, flying freely 
in the afternoon,” and that “the air often seemed alive with these 
insects.” In 1882 William Buckler * made some study of the habits 
of the species, which he fed upon the “ locust bean” of commerce, 
describing the eggs, larva, pupa, and cocoon. During the same year, 
and in the same periodical,’ Mr. George T. Porritt published a 
supplementary note expressing the opinion that the species is double 
brooded, and mentioned dried figs as a food material. To this the 
same writer added the observation that the larve remained in their
