Museum specimens of Aedes (Neomelaniconion) circumluteolus (Theobald, 1908) and unidentatus McIntosh, 1971 and museum and living specimens of Ae. (Neo.) mcintoshi Huang, 1985 were exposed to daylight. The yellow or golden yellow scales of the vertex and scutum and all pale scales on other parts of the body were completely or nearly completely bleached to white or silvery white in eight days in males and in 14 or 15 days in females. In some specimens the integument faded and in circumluteolus the brown scales of the scutum became paler. The bleached museum specimens of circumluteolus and mcintoshi agree in all significant details with the types of Ae. (Neo.) albothorax (Theobald, 1907),and pallidus (Theobald, 1907), respectively. The names circumluteolus and mcintoshi are, therefore, junior subjective synonyms of albothorax and pallidus. Reasons for conserving the names albothorax, circumluteolus and mcintoshi are given.
