LEPIDOPTERA. 301 
are called Lichinées, on account of their colour, which resembles 
that of a Lichen. Their four anterior membranous feet are the 
shortest, and they walk in the manner of the Geometre. 
N. pacta, Fab. Distinguished from the others by the red co- 
lour of the under part of its abdomen. It is only found in the 
north of Europe *. 
The caterpillars of some have but twelve feet. The superior 
wings of the perfect Insect are frequently ornamented with 
golden or silver spots. Such are the two following species f. 
N. gamma, Fab., Rees., Ins. I, Class III, Pap. Noct., V. The 
thorax crested; superior surface of the upper wings brown, 
with lighter shades of the same colour, and a golden spot form- 
ing a lambda or gamma, laid on the side, in the middle. By 
pressure, two tufts of hairs may be made to protrude from the 
extremity of the male’s abdomen. The caterpillar lives on va- 
rious culinary vegetables. 
N. Chrysitis, Fab.; Esp., Noct., cix, fig. 1—5. Superior 
wings light brown, traversed by two bands of the colour of 
polished brass. 
Some caterpillars, like those of the V. Verbasci, N. Artemisia, 
N, Absinthit, &c., have the habit of feeding on the flowers of 
plants peculiar to them f. 
Other species of Noctuz have pectinated antenne, like the 
N. graminis—P. gramminis, L.—whose caterpillar sometimes 
ravages the fields of Sweden. 
The sixth section of Nocturnal Lepidoptera, or that of the Pua- 
Lan& Torrricrs, L., is closely allied to the two preceding ones. The 
superior wings, of which the exterior margin is arcuated at base and 
then narrowed, their short and wide figure forming a truncated oval, 
give a very peculiar appearance to these Insects. They are called 
in France, Phalénes a larges épaules, and Phalénee & chappe. They 
have a distinct proboscis, and their inferior palpi are usually almost 
similar to those of the Noctuew, but somewhat salient. 
They are small-and prettily coloured; their wings are tectiform, 
but flattened almost horizontally, and always laid on the body. In 
this case the upper ones are slightly crossed along the inner margin. 
Their caterpillars have sixteen feet, and their body is closely shorn, 
or but slightly pilose. They twist and roll up leaves of trees, con- 
necting various points of their surface at different times by layers of 
silken threads running in one direction, and thus form a tube, in 
which they reside, and feed in tranquillity on their parenchyma. 
Others form a nest by connecting several leaves or flowers with silk. 
Some of them inhabit fruits. 
* These two species belong to the genus Catacola, Ochsenheimer. P 
+ Genus Plusia of the same. 
{ They belong to the genus Cucullia of Schrank and other Lepidopterologists. For 
the other species see Olivier, Encyc. Méthod., art Noctuelle; Lat. Gener. Crust. 
et Insect., IV, p. 224, and in particular Ochsenheimer’s work on the Lepidoptera of 
Europe, and the Hist Nat. des Lépid. de France of Godart, now continued by M. 
Duponchell, well known to entomologists by his interesting Monograph of the genus 
Erotylus already quoted, and other Memoirs.
