THE JOINTED ANIMALS 



Calocoris stria tell us (much enlarged). 



presenting a considerable variety of color, 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 through- 

 out 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. affinis 

 may be recognized by the brown color 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 color, with pale 

 yellow or white elytra, marked with a 

 brown spot at the base and another at the 

 extremity. Aradus corticalis is a com- 

 mon species, found under bark, which we 

 figure to give an idea of the flattened 

 form and membranous appearance of the 

 bugs of the subfamily Aradince. These 

 bugs have a longer rostrum and more 



cylindrical antennae than those of the Tingitina:. The bedbug (Cimex ledularius} , 

 which also belongs to this family, is a wingless species, with four-jointed antenna, 

 and a beak composed also of four joints, which can be turned back to lie in a groove 

 under the throat. The shape of the insect may be seen from the figure, as well as 

 the two lobes lying at the sides of the scutellum, which are all it has in the way of 

 elytra. Closely-allied species are found in dovecots, and in the nests of martins 

 and bats. The Rednviidce are predaceous bugs, in which the head, narrowed be- 

 hind in the form of a neck, carries two ocelli in addition to the compound eyes. 

 Their antennae are composed of four joints, though these are often subdivided in 

 such a way that the number may appear much greater. The rostrum is short 



Tingis affinis (X8); 2. Aradus corticalis (X6); 3. Cimex 

 lectularius (much enlarged).
