reject the name Cimex, which Olivier proposed for the bedbug (or chincli) 

 in 1789. They also reject Pentatoma of this author, using Cimex instead.

Fam. 15. Capsidce. This family contains Capsus, Phytocoris, ajid other 

 genera of small and ornamental insects found upon plants, upon the juices 

 of which they seem to feed. They run and fly well ; they have no stem- 

 mata, the ovipositor is contained in a groove of the abdomen, and the 

 rostrum is four-articulate. 



Fam. 16. LygceidcB. This family is allied to the preceding, the species 

 are small or of medium size, and the colors varied. They inhabit plants. 

 P.yrrhocoris apterus [pi. SO, fig. 60). 



Fam. 17. Coreidce. The first articulation of the antennae is as long as 

 the head or longer, and the last one thickened or lengthened in this family. 

 These insects are large, of varied colors and active habits, and they 

 frequent plants. In some species the hind feet have various forms and 

 foliaceous expansions. Coryzus hyoscyami {pi. 80, fig. 61). 



Fam. 18. Scutelleridce. Some of the members of this family have the 

 scutellum so large as to cover the abdomen and wings. The body is 

 robust, sometimes subglobular, the antennae long, and the feet slender. 

 Some of the species are above the medium size, and many of them are 

 ornamented with brilliant colors. They are vegetable feeders, sucking the 

 juices of leaves, and some of them have glands which secrete a fluid with 

 a very disagreeable scent. There are three sub-families corresponding to 

 the genera Scutellera, Cimex, and Cydnus {fig. 62). The first have a 

 very large scutellum ; the second and third a smaller one ; and the third is 

 distinguished from the second by having spinose feet. Fabricius left the 

 name Cimex for insects subsequently named Pentatoma, with which Amyot 

 and Serville agree, although they admit a genus Pentatoma. Other authors 

 improperly reject the name Cimex entirely. Cimex rufipes {pi. 80, fig. 

 66). This species is also referred to the genus Tropicoris of Hahn, and to 

 Pentatoma. Pentatoma juniperinus {fig. 63) ; P. haccarum {fig. 64) ; 

 Acanthosoma {fig- 65). 



Order 10. Strepsiptera. This order of Kirby was subsequently named 

 Rhipiptera by Latreille. It includes a limited number of insects of small 

 size, which are parasitic in the bodies of Hymenoptera. The anterior 

 wings are replaced by a kind of twisted halteres, and the posterior ones are 

 large and folded like a fan. The mouth has two small awl-shaped jaws, 

 and two bi-articulate antennas ; the eyes are large, prominent, and lateral, 

 with a few large facets, and these separated by partitions raised above 

 their surface. The antennae are simple or furcate, with few articulations ; 

 the thorax very robust, the metathorax very long, removing the posterior 

 feet far back. The tarsi have from two to four articulations. Specimens 

 of certain wasps and bees may be sometimes seen with the abdomen 

 distorted, and an examination discloses one or more heads of a minute 

 insect sticking from between the segments, which belong to these parasites 

 when near the time of their appearance. Siebold has discovered the 

 winged individuals to be males, and the females to be without wings, and
