MICRO-LE PIDOPTER A. 
Tins division contains an immense host of minute 
Fig. 165 o. 
Social larvffi of Hyponomeuta padella feeding on the apple tree, 
moths, upwards of six hundred species being British, 
They frequently swarm to an extent that renders their 
appearance quite a pest, from the great mischief they 
cause, particularly to woollen goods — cloth, carpets, furs, 
&c. Tinea pellionella feeds on old clothes, in the larva 
state. Tinea biselliella is very destructive to furs of all 
sorts. It also attacks skins, and is a great pest in 
zoological collections. Tinea tapetzella, the Tapestry 
moth, is a most terrible pest in houses, attacking any 
kind of woollen fabric, as does also Tinea sarcitella. 
The larva of Tinea granella is veiy destructive in 
granaries, committing great havoc on grain, upon which 
they feed, and fasten it together with their silken web, 
covering it sometimes as it were with a sheet. Many of 
the species of this family are perfect gems, such as 
Gelechia Ultorella, and several other species of that 
beautiful genus. The larvae of some of these insects 
frequently prove very injurious to trees. The Chry- 
soclista Linneella, in the larva state, feeds under the 
bark of lime tree.s, and commits great damage. The 
genus Lilhocolletes contains a perfect assemblage of 
insect gems. They mine the leaves of trees, shrubs, 
and plants, in their larva state, a single leaf furnishing 
all the food they require ; but their numbers often 
render their depredations serious. 
Fig. 165 a, represents the larvae of Hyponomeuta 
padella feeding on the apple tree, under a common 
web. These fruit trees are frequently entirely defoliated 
by them. 
The following are the families contained in this 
division of the Lepidoptera : — 
1. Exapatidce; 2. 2'ineidm; 3. Hyponomentidm ; 4. Plutellidm ; 
5. Gelechidm ; 6. Glyphipierygidoe ; 7. Argyresthidce ; 8. Grad- 
lariidce; 9. Coleophoridce ; 10. Elachistidx; 11. Lithocolletidiai; 
12. Lyonetidoi; 13. Nepticulidce. 
Order II. — RHYNCHOTA. 
The insects of this order, generally named Hemiptera, 
are called Rhynchota by Fabricius, from the straight 
beak which they have on the under side of the head. 
There are two sections, named Hemiptera and Homop- 
tera, though writers have named the ioxm&v Hemipitera 
Heteroptera, and the latter Hemiptera Homoptera. 
Sub-order — HEMIPTERA. 
The sub-order Hemiptera contains a very large 
number of insects, nearly all of which emit a pecu- 
liarly disagreeable odour. Hahn, Hope, Burmeister, 
Amyot and Serville, Dohrn, Stahl, Dallas, and others, 
have specially signalized themselves by their attention 
in modern times to this order. 
I give Mr. Westwood’s arrangement of the families 
of Hemiptera : — 
Sect. I. Hydrocorisa. 
Family 1. NotonectidcB ; 2. Nepidce. 
Sect II. Aurocorisa. 
Family 1. Gulgulidm; 2. Acanthiidm; 3. Hydrnmetridce; 4. 
Reduviidm; 5. Cintiddm; 6. Tingidm; 7. Capsidce; 8. 
Lygceicke; 9. Coreidce; 10. Scutelleridce. 
voE. II. 90 
Families— SCUTELLERID^ and PENTA- 
TOMIDAE. 
The first family is named Shield-bug, from the enor- 
mously developed scutellum — a part of the insect gene- 
rally of large size, also, in the Pentatomiclae. 
Many of the exotic species of Scutellera are most 
brilliant when alive ; and by immersing the dried, 
faded specimens a sufficient time in alcohol, much of 
their pristine beauty may be regained. Well is the 
genus Callidea called beautiful. On Plate 8, fig. .3, 
is figured the red and black striped European Tetyra 
nigrolineata. 
Fig. 166, a, is that of Chairocydnus foveolatus, with 
a remarkably broad head and abbreviated body. The
