64 H AUSTELL ATA. — LEPIUOPTEKA. 



Larva various, with from fourteen to eigliteen legs, naked or pilose; either ex- 

 posed, or concealed within a convoluted leaf, or between the surfaces of one; 

 or in some few instances within the pith of plants, or in woollens, flannel, 

 and other stutFs, of which it forms its cocoon ; or the latter is placed in a 

 folliculus amongst its pabulum or beneath the earth: sometimes suspended, 

 after the manner of some of the Duima, with a slender thread. 



This division is unquestionably the most numerous portion of this 

 beautiful order of insects, at least in these temperate regions ; the 

 groups of which it is composed differ considerably in appearance ; 

 nevertheless they may be recognised from the other sections by their 

 general habit : in some the anterior wings are broad, with the costal 

 margin more or less dilated at the base, the wings during repose in 

 these forming with the body a broad obtuse triangle, the rayed sides 

 being deflexed, accompanied generally with two short, horizontally 

 porrected, palpi; others have the anterior wings narrow and slender, 

 and while at rest convoluted round the body, with the palpi some- 

 times very short and depending, or elongate, slender, incurved, and 

 two in number : another group has four distinct, sometimes porrected, 

 palpi : others again have the wings cleft into plumeleto, varying in 

 number. It is therefore evident that, from these discrepancies of 

 form and structure, these insects require furtlier subdivision ; the 

 following families may consequently be formed therefrom, and may 

 be recognised by the annexed concise characters. 



From the greater portion of the species appearing on the wing in 

 the evening, I have given them their present appellation ; though 

 many of them, especially those of brilliant metallic colours, delight in 

 flying in the full glare of sunshine, while some fly in the night, as 

 hereafter more particularly pointed out.
