go BRITISH MOTHS 



wliicli, like the Fiiniea', has a wingless female furnished with antennaj and feet. Fumea difi'ers 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 antennre of tlie males are very strongly 

 pectinated. Tiie mouth is obsolete. The species arc termed Sack-triigers by the Germans, in consequence of 

 the larvte residing in cases formed of bits of twigs, grass, &c., fiistened together with silk, which tliey 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 iu their case, so that the moth is able to force its chrysalis 

 )Kirtly out of the opposite end, so as to enable it to make its escape. From various observations it moreover 

 a])pears that the females have the power of producing fertile eggs without a previous impregnation, as is also 

 the ease with the Aphida\ 



The species of the present genus are rare, and rather confused in their synonymes. I have adopted the 

 nomenclature given by JVIr. Curtis, who had the opportunity of examining Mr. Ilaworth's typical specimens 

 previously to their dispersal.

Synonymes. — Bombyx putlu, E&per ; Orliscnheiau-r; BoIsJuval ;

Fumea mvscea^ Ilawortli. 



This is the smallest species in the genus, not measuring more than five lines in e.xpanse ; it has the wings 

 rounded, blnek-brown, unspotted, with the entire margin hairy ; the antcnn;e are but slightly pectinated. This 

 species is very rare. 



The larva case, figured between figures 1 and 4, is very long and slender, and of a pale-greyish bufif 

 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. — Pst/ehe plumel/a, C'uitis (Iliiljncr, t. 1, f. 7?) Fumea pectinea, Ilawortl]. 

 Fmnca pectiiiellu, Stejilieiis ; Fabriciiis. 



This very rare species is rather larger than the preceding, the wings are rounded, ashy brown, and 

 somewhat transparent ; they arc without siiots, but have the entire margin darker. The antennie of the 

 males, according to Curtis, are twenty-jointed, sixteen having rays which ajipear to be shorter than in P. radiella, 

 the wings are rather browner, and the superior scarcely so broad as in that species. It is to be observed, 

 that Ochsenheimer and Boisduval give Iliibner's T. plumella as identical with pulla, the plumella of those 

 authors and of the Wiener Verzeichniss being a distinct but closely allied species. 



SPECIES 3.— FUMEA PECTINELLA. Plate XVI., Fig. 15. 



SvNONYMFa. — Sombi/i pcciinelld , Fdhtmus ; Hiibncr; Ocljsenlieimer ; Curtis. Fumea plumea, iluworth ? 



Fumea pulla? Stephens. 

 This species resembles P. plumella, but is rather larger; all the wings are of an ashy colour, and hyaline, 

 with the margin brown ; the antennse are clear brown, and the body clothed with black hairs ; the cilia of the 

 wings is yellowish grey. This species is very rare in this country. 



SPECIES 4— FUMEA RADIELLA. Plate XVI., Fig. 13.
