INSECTA. 407 
Family XXVIII. Diurna. Wings mostly erect when the in- 
sect is seated, never bridled by a retinaculum. Antenne in by far 
the most clavate, abruptly terminated by a capitulum, in a few 
filiform or subsetaceous, with apex more slender, uncinate. Ocelli 
none. The caterpillar always with sixteen feet. Chrysalis almost 
always naked, angulate, attached posteriorly by threads, or sus- 
pended vertically, or affixed by a transverse silken cord expanded 
above the middle of the body. Flight of Imago diurnal. 
Butterflies (Rhopalocera Poispuv.) These insects have usually 
clubbed antennz, which is the case with all our domestic species ; 
when at rest they erect their wings, so that the upper surface of the 
wing is turned inwards. The genus Papilio of Linnxus corresponds 
to this family of later writers.

Phalanx I. — Posterior tibie, as in the preceding families, 
spinose not only at the extremity, but also on the inside before the 
extremity. (Caterpillar very often living among leaves that have 
been spun together. Chrysalis smooth, folliculate, or tied up by 
a transverse thread.) 
Urania Fasr. Antenne filiform, more slender at the apex, 
and arcuate or uncinate. Labial palps triarticulate, elongate, slen- 
der, with second joint greatly compressed, third slender, subcylin- 
drical, almost naked. Wings broad, large.

the pupa figured in Trans. of the Zoolog. Soc. I. 2, 1834, pp. 179—189, Pl. 
26. The larva is thick, with a few hairs, in form not unlike a caterpillar of 
Callimorpha, but with a very large head; the web is thin, so that the pupa 
is visible through the meshes. These species belong to the genus Cydimon 
of Dauman, Pap. (Zques) Orontes L. (CRAMER, UVitl. Kap. Tab, LXXx11. figs. 
A, B) to the genus Nyctalemon of the same.

DUVAL, Nouv. Ann. du Muséum, 1. 1833, Pl. 14, figs. 1, 2, has a spiny 
caterpillar with the first four membranous feet short, so that it moves like 
a geometric caterpillar. It does not spin itself up when about to change 
to a pupa, but affixes itself by means of a thread stretched transversely over 
the body, like the caterpillars of the genus Pieris, &c. This species, placed
