208 INSECT A. 
Other species of Noctuz have pectinated antennz, like the 
N. graminis—P. graminis, L.—whose caterpillar sometimes 
ravages the fields of Sweden. 
The sixth section of Nocturnal Lepidoptera, or that of the Pua- 
Lanz Torrrices, 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 trun- 
cated oval, give a very peculiar appearance to these Insects. They 
are called in France Phaléenes & larges épaules, and Phalénes a chappe. 
They have a distinct proboscis, and their inferior palpi are usually 
almost similar to those of the Noctuz, 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. 
The posterior extremity of the body is narrow in several; they are 
styled by Reaumur ** chenilles en forme de poisson.”? Their cocoon 
has the figure of a bateau, and is sometimes of pure silk, and at 
others mixed with foreign matters. 
The Tortrices compose the subgenus 
Pyratis, Fab.(1) 
P. pomana, Fab.; Rees., Insect., I, Class IV, Pap. Noct., 
Lepidoptera of Europe, and the Hist. Nat. des Lépid. de France of Godart, now 
continued by M. Duponchel, well known to entomologists by his interesting Mo- 
nograph of the genus Erotylus, already quoted, and other Memoirs. 
(1) Certain divisions established in our Gen. Crust. et Insect., IV, 230, divis. 2 
and 11, it has appeared to us—Fam. Nat. du Rég. Anim., 476—might be formed 
into separate subgenera. 
Those species—Toririx dentana, Hiibn.—in which the wings have a peculiar 
appearance, the upper ones being somewhat raised at the exterior ‘margin, and 
inclined on the opposite one, and of which the caterpillars have membranous feet 
of a peculiar form, compared by Reaumur to wooden legs, compose the subgenus 
Xytoropsa. Others—Pyralis rutana, wmbellana, heracleana—in which the inferior 
palpi curve over the head like horns and terminate ina point, form that of the 
Volucre—Voxvcra.
