THE IDENTITY OF AN INTRODUCED PSYCHID, 
FUME A CASTA PALLAS (Lepidoptera, Psychidse) 
By Frank Morton Jones and Donald W. Farquhar 
When in 1931 the larvae and larval cases of this small 
Psychid were first observed in the Boston area in Mass., it 
was apparent that the insect could not be identified with 
any known North American species of the family. A very 
few adult males were secured in 1932, and these sufficed to 
refer the insect to the European genus Fumea, hitherto un- 
recognized in the western hemisphere, and to indicate that 
we were dealing with an introduced species. Abundant 
material of both sexes, bred in 1933, confirmed the generic 
reference and permitted a careful comparison with exotic 
material and the literature of the genus. Since the insect 
has already extended its range in two States and is destined 
to take permanent place in our fauna, it seems advisable, 
in addition to the biological notes included in the preceding 
paper, to put on record those details of its structure which 
should suffice for its ready recognition in this country. 
Fumea , in much of its extensive European literature, 
obviously has been made to include species structurally 
divergent, and even under identical specific names there 
has been such lack of agreement that mixed series or mis- 
taken identities seem the only explanation. We have prof- 
ited by the careful work of Chapman, of Tutt, and of Bur- 
rows, and have accepted their identifications of casta Pallas, 
the most abundant and widely distributed species of the 
genus, as the basis of our comparisons. That some of the 
characters we describe and illustrate should be generic 
rather than specific, is necessitated by the confusion of 
literature we have indicated. In| addition to the general 
habitus of the insect, we have found useful for comparison 
the following characters :

is an 11-7 veined insect. In both wings the media divides
