1934 ] Identity of an Introduced Psychid 35 
Pupa of male (Plate 3, figs. 9 and 10) . — In the male pupa 
of Fumea, the fore wings, the legs, and the antennae are 
free at their apices, standing out slightly from the abdomen, 
so that according to the degree of its extension they may 
overlap the fifth abdominal segment or may barely reach 
its anterior margin. As far as we have been able to make 
comparison, the general characters of the pupa as shown 
by our illustration are in accord with English casta. 
We are aware that the form of the generic name (Tutt, 
British Lepidoptera, II, 317, 318, 1900), its genotype, and 
the properly included species, are all subjects for differ- 
ences of opinion and will require review, and that in the 
European literature the status of casta Pallas, with refer- 
ence to its synonyms, its geographical races, and the num- 
ber of possibly distinct but closely related species remains 
a matter of opinion. Tutt follows Chapman in treating in- 
termediella Bruand as a race intergrading with casta, while 
Seitz considers intermedieila a pure synonym. By Tutt’s 
analysis, in this “protean species represented by various 
local races,” our insect in size and structure comes nearest 
to variety intermedieila, which is supposed to be of more 
frequent occurrence on the European mainland rather than 
in England. In view of the impossibility of determining the 
place-origin of our insect and of the intergradation of the 
partially localized and illy-defined varieties or races of 
casta, we believe that for the present this recent addition 
to our fauna may be most satisfactorily designated in our 
literature by the oldest and best-known name for this 
widely-distributed insect, Fumea casta Pallas.
