304 INSECTA, 
whose caterpillars have fourteen legs, and roll up leaves. In the 
perfect Insect the inferior palpi are elongated and recurved. Its 
wings and body, on the sides of which the former are extended hori- 
zontally, form a sort of delta, marked by a re-entering angle in the 
posterior side, or appearing to be forked. The antenne are usually 
pectinated or ciliated. 
The Deltoides form the subgenus 
Herminia, Lat., 
Which belongs to the division of the Pyralides of Linnzus, and 
is composed of the genus Hyblaa, Fab., and of several of his 
Crambi*. 
The ninth section cf the nocturnal Lepidoptera, that of the Tr. 
NEITES— TJineites, Lat.; Phalena tine, L., and most of his P. py- 
ralides—comprises the smallest species of this order. Their cater- 
pillars are always closely shorn, furnished with sixteen feet at least, 
and rectigrade, living concealed in dwellings fabricated by them- 
selves, either fixed or movable. Here the wings form a sort of elon- 
gated and almost flattened triangle, terminated by a re-entering 
angle; such are the Pyra/ides of Linnzeust; they have four distinct 
and usually exposed palpi. ‘There, the superior wings are long and 
narrow, sometimes moulded on the body, and forming a sort of 
rounded roof to it, sometimes almost perpendicularly decumbent and 
laid on the sides, and frequently raised or ascending posteriorly like 
the tail of a cock. In both cases the inferior wings are always wide 
and plaited. These species also frequently have the four palpi ex- 
posed. 
All the caterpillars, whose habitations (sheaths) are fixed or im- 
movable, are the Pseudo- Tinee of Reaumur; those which construct 
portable ones, which they transport with them, are true Tinez, 
The substances on which they feed, or on which they reside, fur- 
nish the materials of the structure. 
Of those sheaths which are composed of vegetable matters, many 
are very singular. Some, like those of the Adele, are covered ex- 
teriorly with portions of leaves laid one over the other and forming 
a sort of flounce: others are in the form of a bat, and sometimes den- 
tated along one of their sides. The material of some of them is 
diaphanous, and as if cellular or divided by scales. 
The caterpillars of the true Tineze, commonly called Moths, clothe 
themselves with particles of woollen stuffs, which they cut with their 
jaws and on which they feed, hairs of furs, and those of the skins of 
animals in zoological collections, united by silk. They know how 
to lengthen their sheath, or to increase its diameter by slitting it and 
adding anew piece. In these tubes they undergo their metamor- 
phoses, after closing the orifices with silk. 
Those who wish to become well acquainted with the manner in 
which they construct these habitations, and to acquire a knowledge of 
their various forms and materials, must have recourse to the Memoirs 
of Reaumur, Reesel, and De Geer.
