known. In addition to the normal predacious types which feed upon insects in
general and are more or less beneficial, there are those which invade habitations
in search of bedbugs and other household pests and which often inflict severe
wounds on humans. Triatoma sanguisuga (Lee.), of North America and T. rubro-

jasciata De Geer, a nearly cosmopolitan species, belong to this class. Others,
which suck blood from rodents and other lower animals and man, are carriers
of trypanosomes thai cause serious complications and even death to man.
Triatoma megista (Burm.), T. infestans Klug, T. rubrovaria Blanchard, and
other species transmit Chagas' disease caused by the trypanosome, Trypanosoma
cruzi Chagas, in South America. Triatoma uhleri Nieva transmits Trypanosoma
iriatomre Kofoid and McCulloch among wood rats in California.
Triatoma rubrojasciata (De Geer) is suspected as an agent in the transmission
of kala azar or black sickness in India.
A number of species live under rocks and among debris. The sticky immature
forms are camouflaged under a mass of particles that completely
hide them, as is the case of the masked bedbug hunter, Reduvius personatus
