INSECTS. 
met with in Britain, which may he known by its red and black colours, and the 
want of hind-wings, as well as of a membranous part to its elytra. The plant- 
bugs ( Phytocoridce ) have the following characters. Head triangular in shape, 
tricarinate above, and without ocelli; antennae long, four- 
jointed, with the second joint longest, and the last two very 
slender; rostrum four-jointed, resting against the under side 
of the thorax, and almost reaching to the end of it; tarsi 
three-jointed; elytra with an appendix, or small angular 
piece, divided off by a transverse suture from the rest of 
the coriaceous part of the elytra, and coming between it and 
the membrane. This family is well represented in temperate 
regions, and about three hundred European species are known. 
They are mostly soft-bodied, fragile bugs, presenting a con¬ 
siderable variety of colour, of which green is in many cases 
the predominant tint. They live principally on honey, and 
are to be found on flowers and in meadows. Phytocoris 
tripustulatus, a species with black elytra, marked with three 
orange spots on the outer margin, is common on nettles. We give an enlarged 
figure of another species ( Calocoris striatellus), widely distributed throughout 
Europe, and met with chiefly on umbelliferous plants. The Acanthiidce form a 
family of mostly very small bugs, which are usually without ocelli, and have a 
three-jointed beak—lodged in a groove along the under side of the head—and 
two-jointed tarsi. These bugs frequently have a somewhat peculiar appearance, 
owing to the membranous or vesicular lobes with 
which the thorax, abdomen, and elytra are often 
furnished. For this reason they are sometimes 
known as membranaceous bugs. The species of the 
genus Tingis are seldom more than one-sixth of an 
inch long, and distinguished by the knob-like ends to 
their antennae, as well as by the foliaceous expansion 
of their thorax, and the extension of the latter behind 
to cover the scutellum. The common T. ciffinis may 
be recognised by the brown colour of its body, its 
transparent borders, with transverse brown nervures, 
and the X -shaped spot on the middle of each elytron. 
This species may be found on sandy soil among the 
roots of grasses, or under plants, such as wormwood, 
belonging to the genus Artemisia. Another species ( F.'. pyri) is noted for the 
injury it does to pear trees, by pricking holes in hundreds on the under side of 
the leaves and extracting the sap. It is of a brown colour, with pale yellow or 
white elytra, marked with a brown spot at the base and another at the extremity. 
Arad us corticalis is a common species, found under bark, which we figure to give 
an idea of the flattened form and membranous appearance of the bugs of the sub¬ 
family Aradince. These bugs have a longer rostrum and more cylindrical antennae 
than those of the Tingitince. The bed-bug ( Cimex lectidarius), which also belongs 
to this family, is a wingless species, with four-jointed antennae, and a beak composed 
Calocoris striatellus (much enlarged). 
Pyrrhocoris apterus (three 
times the nat. size).
