It has the same habits and practically the same life cycle as _Cimex lectularius_. Mackie, in India, has found that it is capable of transmitting the Asiatic type of recurrent fever. Roger suggested that it was also capable of transmitting Kala-azar and Patton has described in detail the developmental stages of _Leishmania_, the causative organism of Kala-azar, in the stomach of this bug, but Brumpt declares that the forms described are those of a common, non-pathogenic flagellate to be found in the bug, and have nothing to do with the human disease. Brumpt has shown experimentally that _Cimex hemipterus_ may transmit _Trypanosoma cruzi_ in its excrement. _Cimex boueti_, occurring in French Guinea, is another species attacking man. Its habits and general life history are the same as for the above species. It is 3 to 4.5 mm. in length, has vestigial elytra, and much elongated antennæ and legs. The extended hind legs are about as long as the body. _Cimex columbarius_, a widely distributed species normally living in poultry houses and dove cotes, _C. inodorus_, infesting poultry in Mexico, _C. hirundinis_, occurring in the nests of swallows in Europe and _Oeciacus vicarius_ (fig. 19i) occurring in swallows' nests in this country, are species which occasionally infest houses and attack man. [Illustration: 71. Conorhinus sanguisugus.] _Conorhinus sanguisugus_, the cone-nosed bed-bug. We have seen in our consideration of poisonous insects, that various species of Reduviid bugs readily attack man. Certain of these are nocturnal and are so commonly found in houses that they have gained the name, of "big bed-bugs." The most noted of these, in the United States, is _Conorhinus sanguisugus_ (fig. 71), which is widely distributed in our Southern States. Like its near relatives, _Conorhinus sanguisugus_ is carnivorous in habit and feeds upon insects as well as upon mammalian and human blood. It is reported as often occurring in poultry houses and as attacking horses in barns. The life history has been worked out in considerable detail by Marlatt, (1902), from whose account we extract the following. [Illustration: 72. Beak of Conorhinus sanguisugus. After Marlatt.]
