SYNOPSIS. Dissections of Triatoma infestans and Rhodnius prolixus at various intervals after experimental infection with insect Trypanosomatidae of the genera Blastocrithidia and Crithidia (B. euschisti, C. luciliae, C. acanthocephali and C. mellificae ) disclosed the protozoa to be surviving and in most instances undergoing reproduction in the experimental bugs for as long as 2 months following infection. Epimastigotes and amastigotes were seen in bugs infected with B. euschisti and choanomastigotes and amastigotes were observed in insects experimentally infected with the Crithidia. Since C. acanthocephali and C. luciliae were from clones, this is the 1st finding of these 2 structural types in this genus using cultures originating from a single choanomastigote. In view of the loose host specificity of the insect Trypanosomatidae as further emphasized by this work, it would appear that the necessity is increased for field workers in trypanosomiasis and leishmaniasis areas of the world to become well acquainted with the infective potentialities of the insect trypanosomatids of their areas for the vectors of Trypanosoma and Leishmania along with the possible association in nature of these vectors with insects which might harbor insect‐limited Trypanosomatidae.
