Exhibition of Autogenous and Stenogamous Characteristics by Theobaldia subochrea, Edwards (Diptera, Culicidæ)

Abstract

OF the various idiosyncrasies of mosquitoes, laying fertile eggs without a previous meal of blood (autogeny) and mating within very small cages (stenogamy) are among the most unusual. Exhibitions of the former peculiarity have hitherto been provided exclusively by different strains of the mosquito which Roubaud has named Culex pipiens var. autogenicus¹ but for which (as previously stated) we advocate the adoption of a different specific name². The latter peculiarity—stenogamy—is known to be a characteristic of the above-mentioned species and also of two others, namely, Aedes aegypti and Anopheles maculipennis var. atroparvus.
