which, like the Fumez, has a wingless female furnished with antenne and fect. Fumea differs from Psyche in 
the very broad and hairy fore wings (occasioned by the singular dilatation of the costal region, which drives the 
. veins far backwards), as well as in the arrangement of the veins. The antenne of the males are very strongly 
pectinated. The mouth is obsolete. The species are termed Sack-triigers by the Germans, in consequence of 
| the larve residing in cases formed of bits of twigs, grass, Xc., fastened together with silk, which they carry about 
with them. When full fed, they fasten the end, previously occupied by the fore part of the body of the cater- 
pillar, to the leaves of branches of the trees on which they reside ; and they have the further instinct, previous to 

undergoing their transformations, to turn themselves in their case, so that the moth is able to force its chrysalis 
partly out of the opposite end, so as to enable it to make its escape. From various observations it moreover 
appears that the females have the power of producing fertile eggs without a previous impregnation, as is also 
the case with the Aphid. 
The species of the present genus are rare, and rather confused in their synonymes. I have adopted the 
nomenclature given by Mr. Curtis, who had the opportunity of examining Mr, Haworth’s typical specimens 
previously to their dispersal.

SPECIES 1.—FUMEA PULLA. Puare XVI., Fie. 12. 
Synonymes.—Bombyx puila, Esper; Ochsenheimer; Boisduval ; Fumea Bombycella, Stephens 4 
Stephens ? ? Tinea plumelia, Hiibner ? ? 
Fumea muscea, Haworth. 
This is the smallest species in the genus, not measuring more than five lines in expanse ; it has the wings 

rounded, black-brown, unspotted, with the entire margin hairy ; the antenne are but slightly pectinated. ‘This 
species 1s very rare. 
The larva case, figured between figures 1 and 4, is very long and slender, and of a pale-greyish buff 
colour ; the empty chrysalis of the male is represented as partly protruding from the extremity, the male moth 
having made its escape. 

SPECIES 2.—FUMEA PLUMELLA. 
Synonymes.— Psyche plumella, Curtis (Hiibner, t. 1, f. 7?) Fumea pectinea, Haworth. 
Fumea pectinella, Stephens ; Fabricius. 
This very rare species is rather larger than the preceding, the wings are rounded, ashy brown, and 
somewhat transparent; they are without spots, but have the entire margin darker. The antenne of the 
males, according to Curtis, are twenty-jointed, sixteen having rays which appear to be shorter than in P. radiella, 
aia the wings are rather browner, and the superior scarcely so broad as in that species. It is to be observed, 
sao that Ochsenheimer and Boisduval give Hiibner’s T. plumella as identical with pulla, the plumella of those 
authors and of the Wiener Verzeichniss being a distinct but closely allied species.
