LEPIDOPTERA. 209 
xiii. Cinereous-grey; superior surface of the upper wings finely 
striped with brown and yellowish, with a large spot of golden- 
red. 
The caterpillar feeds on the seeds of the apple, and the female 
deposits her eggs on their germ. 
P. vitis, Bosc., Mem. de la Soc. d’Agric., Ii, iv,6. Superior 
wings deep greenish, with three oblique, blackish bands, the 
last terminal. 
Its caterpillar is very injurious in vineyards. 
P. prasinaria, Fab.; Rees., Insect., IV, x. The largest spe- 
cies known; superior surface of the upper wings light green, 
with two oblique white lines. 
On the Oak, &c. Its caterpillar is one of those that Réaumur 
compares toa fish. Its cocoon has the form of a batteau(1). 
The seventh section of the Nocturna, that of the GromerrRa— 
Phalenites, Lat.; P. geometrz, L.—comprises Lepidoptera in which 
the body is usually slender, the proboscis either nearly wanting, or 
generally but slightly elongated, and almost membranous. The in- 
ferior palpi are small, and almost cylindrical. The wings are am- 
ple, extended, or tectiform and flattened. The antenne of seve- 
ral males are pectinated. The thorax is always smooth. The cater- 
pillars usually have but ten feet; the others present two more, and 
those at the anus always exist. Their peculiar mode of progression 
has caused. them to be styled Arpenteuses, Geometrx, or Measurers. 
When about to advance, they first cling with their anterior or squa- 
mous feet, then elevate their body so as to form a ring, in order to 
approximate the posterior extremity of the body to the anterior, or 
that which is fixed; they cling with the anal feet, disengage the first, 
and move the body forwards, when they recommence the same ope- 
ration. Their attitude when at rest is singular. Fixed to a branch 
of some plant by the anal feet only, their body remains extended in 
a straight line in the air, and absolutely motionless. So closely does 
the skin resemble the branch in its colour and inequalities, that it 
Finally, others again in which the wings are narrow and elongated, and the infe- 
rior palpi longer and salient, species which closely resemble the Crambi of Fabri- 
cius, near which they must probably be placed, constitute a third subgenus, Pro- 
cerata, of which the Pyrulis saldonana, Fab., is the type. 
For the other species, see Fabricius and Hiibner. 
(1) Messrs Lepeletier and Serville, with the Pyralis Godarti, previously de- 
scribed by them, have formed the new genus Marronuta, differing from others 
of this division in the following characters; the labial palpi shorter than the head, 
with rather indistinct and almost glabrous joints; anterior coxe strongly com- 
pressed, and at least as long as the thighs. -
