The most familiar British species is what is commonly known as the Colewort Bug (_Strachia oleracea_), a very pretty insect, which lives on cruciferous plants, and is said sometimes to be injurious in gardens. [Illustration: Fig. 82.--Catacanthus Incarnatus.] [Illustration: Fig. 83.--Euthyrhynchus Floridanus (Mag.)] Some of the Chinese Bugs belonging to the genus _Tesseratoma_ are the largest species known. _Family 2, Coreidæ._--This family contains a great number of plant-feeding native and exotic species, varying considerably in shape and structure. The majority of European species are, however, of small size in comparison to those found in tropical parts of the world. The insects of this family are rarely adorned with bright colours, different shades of brown being the prevailing tints, although a few of them are gaily adorned. [Illustration: Fig. 84.--Trigonosoma Desfontainei.] In their general habits they much resemble the Shield Bugs. Two British species are _Syromastes marginatus_ and _Verlusia rhombea_. _Family 3, Lygæidæ._--The members of this family are, on the whole, much smaller than the _Coreidæ_, some of the smallest forms of which many of them resemble. [Illustration: Fig. 85.--Cantao Oceliatus (Mag.)] These insects are generally of a red colour, with black bands and spots. Several species are very injurious to cultivated plants. One of the most destructive of all is _Blissus leucopterus_, a black insect with white fore wings, each of which is marked with a large black triangular spot on the outer edge. It measures about an eighth of an inch in length. The young larva is red. In the United States this insect, which abounds to a considerable extent, is called the "Chinch Bug." [Illustration: Fig. 86.--Menenotus Lunatus.] [Illustration: Fig. 87.--Copius Intermedius.] _Family 4, Pyrrhocoridæ._--This family of bugs abounds in all parts of the world, and in Europe and Britain is undoubtedly the most numerously represented of all the families of bugs. A very common species in this country found on nettles is _Phytocoris tripustulatus_, which is about one-sixth of an inch in length, and generally yellowish in colour. _Family 5, Capsidæ._--This family contains a great number of small species of variegated colours, which feed exclusively on the sap of plants or the juice of fruits. A rather small species (_Capsus ater_) is common upon herbage. The male is entirely black; in the female the head and thorax are reddish. The genus _Miris_ and its allies include elongated species, which are found chiefly in grassy places. _Family 6, Tingididæ._--The species of this family differ considerably among themselves in size, structure, and habits; and although the majority of them are carnivorous, others, especially among the smaller species, are herbivorous. One species (_Tingis pyri_), found in our own country, is sometimes very injurious to pear trees. [Illustration: Fig. 88.--Tingis Pyri (Mag.)]
