SIMOES (Mem. Inst. Oswaldo Cruz, 39 (1943), No. 3, pp. 279-290, illus. 1; Eng.
abs., p. 289).-Notes on the geographic distribution of the reduviid vectors and
prevalence of Chagas' disease in this region are reported. Five new localities for
Triatoma infestans spontaneously infected with Schisotrypanum cruzi were found.
Verificagao de flagelados semelhantes ao Trypanosoma rangeli Tejera, em
Rhodnius prolixus alimentados em caso de doenca de Chagas na Venezuela

on a case of Chagas' disease in Venezuela], E. DIAS and J. F. TORREALBA
(Mern. Inst. Oswaldo Cr1uz, 39 (1943), No. 3, pp. 265-278, illus. 35; Eng. abs.,
pp. 276-277).-Large crithidia morphologically like T. rangeli and metacyclic forms
of Schizotrypanum were observed in the feces' of laboratory-bred R. prolixus 65
days after feeding on a case of Chagas' disease. A strain of Schizotrypanum identical
with that found in an inoculated guinea pig fed on the patient's blood was
isolated from the intestinal contents of this infected reduviid bug. In the gut of
this and other species fed on animals infected with that strain, only S. cr uzi-like
flagellates were encountered. The theory is' suggested that T. rangeli is a Schizotrypanum
pathogenic to man and that certain of its forms in the insect vector are

reduviid bugs T. rubrofasciata and Panst.rongylus megistus with flagellates of the

CAMPOS SEABRA (Mem. Inst. Oswaldo Cruz, 39 (1943), No. 3, pp. 301-329, illus.
95; Eng. abs., pp. 324-325).-An adult reduviid bug (T. rubrofasciata) was found
infected with flagellates referable to T. conorrhini; the detailed findings and their
significance are discussed. The authors believe T. conorrhini to be the only species
of Trypanosoma transmitted by reduviid bugs; a list of some 13 others species
tested under experimental conditions by various authors-all with negative resultsis
